Introduction





Reef
Global Energy VI, L.P. (the Partnership) is the first in a series of four Nevada
limited partnerships comprising a program called Reef Global Energy Ventures II
(the Program). The Partnership was formed in the state of Nevada on July 18,
2005.  The Partnership purchased working interests in oil and gas
prospects and participated in the drilling of wells on those prospects. The
primary objectives of the Partnership are to generate revenue from the
production of crude oil and natural gas, distribute cash to the partners, and
provide tax benefits. Reef Oil & Gas Partners, L.P. (Reef) is the managing
general partner of the Partnership.





The
Partnership was formed to drill, complete and own working interests in oil and
gas wells located onshore in the continental United States or in U.S. coastal
waters in the Gulf of Mexico. The Partnership purchased working interests in
twenty developmental prospects (as defined below) upon which it drilled
twenty-seven developmental wells. The Partnership purchased working interests in
fourteen exploratory prospects upon which it drilled sixteen exploratory and
eight developmental wells. These prospects are located onshore in Texas,
Louisiana, Oklahoma, New Mexico and in U.S. coastal waters in the Gulf of
Mexico. In 2008, the Partnership completed drilling operations with the capital
previously raised by the Partnership. The Partnership will not purchase
additional prospects. In accordance with the Partnership’s limited partnership
agreement (the Partnership Agreement), the Partnership may conduct additional
drilling operations to fully develop those prospects already owned by the
Partnership.





Other
partnerships formed as a part of the Program also own working interests in some
of the prospects owned by this Partnership. Reef also purchased working
interests in certain partnership prospects for some of the other partnerships it
manages. In instances where the percentage ownership of the Partnership and
Reef-affiliated entities in a prospect is large enough, Reef Exploration, L.P.
(RELP), an affiliate of Reef formed in 2005, serves as operator of the prospect.
RELP serves as operator of eight developmental and four exploratory Partnership
prospects. RELP operates one successful developmental well and two successful
exploratory wells located on three Partnership prospects.  In this
Annual Report on Form 10-K (Annual Report), we use the term “successful” to
refer to wells that are drilled, tested, and either capable of or actually
producing in commercial quantities. We use the term “unsuccessful” to refer to
wells that do not meet one or more of these criteria.





Acquisition
and Drilling of Undeveloped Prospects





The
Partnership purchased working interests in eight developmental and four
exploratory prospects internally sourced by RELP, and twelve developmental and
ten exploratory prospects generated by and purchased from third parties. A
"prospect" is generally defined as a contiguous oil and gas leasehold estate, or
lesser interest in a leasehold estate, upon which drilling operations may be
conducted. A prospect may be characterized as "exploratory" or "developmental"
based upon the type of well to be drilled on the prospect.  A
developmental well is a well drilled within a proved area of an oil or gas
reservoir to the depth of a stratigraphic horizon known to be productive.
Generally an exploratory well is any well that is not a developmental well,
including wells drilled to find and produce crude oil or natural gas in an
unproven area, wells drilled to find a new reservoir in a field previously found
to be productive of crude oil or natural gas, or wells drilled to extend a known
reservoir.





Prospects
were evaluated utilizing data generated by RELP or provided by unaffiliated
third parties to RELP. This data included well logs, production records from
other area wells, seismic, geological and geophysical information, and such
other information available and considered useful. Prospects in which the
Partnership purchased a working interest were evaluated by petroleum engineers,
geophysicists, geologists, and other technical consultants employed by or
retained by RELP on the Partnership's behalf.





The
Partnership prospects were acquired pursuant to an arrangement in which the
Partnership purchased part of the working interest. A working interest bears a
specified portion of the costs of development, operation and
maintenance.  A working interest is subject to landowners' royalty
interests and may be subject to other royalty interests payable to unaffiliated
third parties. Where the Partnership acquired less than 100% of the working
interest, costs were reduced proportionately. The Partnership Agreement
prohibits Reef or any of its affiliates from retaining any overriding royalty
interest, that is, any royalty interest that would be paid out of the
Partnership's working interest, in any working interest purchased by the
Partnership. The Partnership is a non-operator working interest owner in all
prospects purchased by the Partnership.

Consulting
Agreements for Prospect Acquisitions





Reef
entered into three agreements (the CMI Agreements) with Challenger Minerals Inc.
(CMI), a subsidiary of GlobalSantaFe Corporation and a screener of oil and gas
prospects in the Gulf of Mexico and North Sea regions. Under the terms of these
agreements, Reef had the opportunity to review and selectively participate in
exploratory and developmental prospects either originated or previewed by CMI.
Reef paid CMI an annual fee for the geological and geophysical services provided
by CMI. Two of these agreements expired in January 2006, and one expired in
November, 2006.





Reef also
entered into an agreement with Access Exploration Corp. (AEC), a screener of
domestic oil and gas prospects both onshore and in the Gulf of Mexico. This
agreement provided Reef the opportunity to review and selectively participate in
exploratory and developmental prospects previewed by AEC. Reef paid AEC an
annual fee for the geological and geophysical services provided by AEC. This
agreement expired in October 2007.





Prospects
approved for acquisition by Reef under these agreements were assigned to this
Partnership as well as other limited partnerships formed as part of the Program.
Each partnership formed as a part of the Program paid Reef, on a pro rata basis,
a portion of the fees paid by Reef under these agreements during the term of the
Program. Total reimbursements to Reef by the partnerships formed as a part of
this Program were equal to the actual fees paid by Reef under these agreements.
The Partnership paid Reef $240,658 as its pro rata share of these fees. This
amount has been capitalized as geological and geophysical costs in accordance
with the full cost method of accounting for oil and gas properties.





Drilling
and Completion Phase of Operations





RELP is
currently the operator of eight developmental and four exploratory prospects,
and serves as operator of three successful wells in which the Partnership has a
working interest. As a well operator, RELP receives operator fees during the
drilling and production phase of each well at the competitive rate in the
geographical area where the prospect is located.  These fees are
charged as a monthly fee per well as agreed to in an operating agreement signed
by the Partnership and participating third parties in the well. The wells are
subject to a model form operating agreement issued by the American Association
of Petroleum Landmen and an accounting procedure for joint operations issued by
the Council of Petroleum Accountants Societies of North America.





On all
prospects currently operated by RELP, drilling operations were contracted to
independent third party drillers, and the costs of the wells to the Partnership
were determined by actual third party costs, plus monthly operator fees charged
at the competitive rate for the geographical area where the wells are
located.





The
Partnership generally pays drilling and completion costs as incurred. Wells
drilled that fail to result in the discovery of commercial quantities of crude
oil or natural gas are plugged and abandoned in accordance with applicable
regulations.  Twenty development wells and eight exploratory wells
drilled by the Partnership were unsuccessful.  Of the twenty
unsuccessful developmental wells, eight developmental wells on the Sand Dunes
prospect in which the Partnership participated have not been plugged and
abandoned at this time.





Production
Phase of Operations





Wells
capable of producing quantities of crude oil and/or natural gas in commercial
quantities were completed by installing all surface equipment necessary to
control the flow of production or to shut down the well, and by installing any
storage facilities, gathering lines, or sales lines required to produce and sell
the crude oil and/or natural gas production from the well. The Partnership
drilled fifteen successful developmental and eight successful exploratory wells.
Five of the successful developmental wells and three of the successful
exploratory wells have ceased production. Twelve developmental and eight
exploratory wells were unsuccessful and have been plugged and abandoned. Eight
developmental wells on the Sand Dunes prospect in which the Partnership
participated and which were classified as unsuccessful during 2008 have not been
plugged and abandoned.


4





The
Partnership has entered into agreements with third party marketers to sell the
crude oil and/or natural gas produced from successful wells on a competitive
basis at the best available terms and prices.  In some cases the
Partnership has elected to sell its production under marketing arrangements
entered into by the operator of the well. Generally, purchase contracts for the
sale of crude oil are cancelable on 30 days' notice, but purchase contracts for
the sale of natural gas may have a longer term.  The Partnership sells
natural gas discovered by it at negotiated prices domestically, based upon a
number of factors, such as the quality of the gas, well pressure, estimated
reserves, prevailing supply conditions and any applicable price regulations
promulgated by the Federal Energy Regulatory Commission (FERC).





Historically,
the oil and gas market has experienced significant price fluctuations. Prices
are impacted by local weather, supply in the area, availability and price of
competitive fuels, seasonal variations in local demand, limited transportation
capacity to other regions, and the worldwide supply and demand balance for crude
oil.





The
Partnership has not and does not expect to engage in commodity futures trading
or hedging activities, or enter into derivative financial instrument
transactions for trading or other speculative purposes. Accordingly, the
Partnership is at risk for the volatility in commodity prices inherent in the
oil and gas industry, and the level of commodity prices has a significant impact
on the Partnership's results of operations.  See "Item 7A.
Quantitative and Qualitative Disclosure About Market Risk."





The
Partnership's share of revenue from productive wells is burdened by and/or
subject to royalties and overriding royalties, monthly operating charges, and
other operating costs.  These items of expenditure involve amounts
payable solely out of, or expenses incurred solely by reason of, production
operations.  The Partnership deducts operating expenses from the
production revenue for the corresponding period.





Major
Customers





The
Partnership sells crude oil and natural gas on credit terms to refiners,
pipelines, marketers, and other users of petroleum commodities. Revenues are
received directly from these parties or, in certain circumstances, paid to the
operator of the property who disburses to the Partnership its percentage share
of the revenues. During the year ended December 31, 2009, one marketer and one
operator accounted for 51.3% and 31.17% of the Partnership’s crude oil and
natural gas revenues, respectively. During the year ended December 31, 2008, one
marketer and two operators accounted for 57.2%, 17.4%, and 11.4% of the
Partnership’s crude oil and natural gas revenues, respectively. During the year
ended December 31, 2007, one marketer and two operators accounted for 53.9%,
23.0%, and 10.4% of the Partnership’s crude oil and natural gas revenues,
respectively. Due to the competitive nature of the market for purchase of crude
oil and natural gas, the Partnership does not believe that the loss of any
particular purchaser would have a material adverse impact on the
Partnership.





Insurance





The
Partnership is a named insured under blowout, pollution, public liability and
workmen's compensation insurance policies obtained by RELP. Such insurance,
however, may not be sufficient to cover all liabilities.  Each unit
held by general partners represents an open-ended security for unforeseen events
including, without limitation, blowouts, lost circulation, and stuck drill pipe
that may result in unanticipated additional liability materially in excess of a
general partner's initial investment in the Partnership.





The
Partnership is a named insured under various insurance policies and intends to
maintain such policies subject to its analysis of their premium costs, coverage
and other factors.  In the exercise of Reef 's fiduciary duty as
managing general partner, Reef has obtained insurance on behalf of the
Partnership to provide the Partnership with such coverage as Reef believes is
sufficient to protect the investor partners against the foreseeable risks of
drilling and production.  Reef reviewed the Partnership insurance
coverage prior to commencing drilling operations and periodically evaluates the
sufficiency of insurance. In no event will the Partnership maintain public
liability insurance of less than two times the Partnership's
capitalization.Subject to the
foregoing, Reef may, in its sole discretion, increase or decrease the policy
limits and types of insurance from time to time as Reef deems appropriate under
the circumstances, which may vary materially.


5





In
accordance with the Partnership Agreement of the Partnership, all general
partner units held by investors were converted into limited partner units during
the third quarter of 2008. At that time, Reef amended the Certificate of Limited
Partnership to effectuate the conversion of the interest of the former non-Reef
general partners to that of a limited partner. Non-Reef general partners will
have limited liability as a limited partner for any Partnership operations
conducted after their conversion date. However, non-Reef general partners that
converted to limited partners continue to have unlimited liability regarding
partnership activities that occurred prior to their conversion
date.





Competition





There are
thousands of oil and gas companies in the United States.  Competition
is strong among persons and entities involved in the exploration for and
production of crude oil and natural gas.  Reef expects the Partnership
to encounter strong competition at every phase of business.  The
Partnership competes with entities having financial resources and staffs
substantially larger than those available to it.





The
national supply of natural gas is widely diversified, with no one entity
controlling over 5% of the supply.  As a result of deregulation of the
natural gas industry enacted by Congress and FERC, natural gas prices are
generally determined by competitive market forces.  Prices of crude
oil, condensate and natural gas liquids are not currently regulated and are
generally determined by competitive market forces.





Markets





The
marketing of crude oil and natural gas produced by the Partnership is affected
by a number of factors that are beyond the Partnership's control and whose exact
effect cannot be accurately predicted.  These factors
include:





·
            the
      amount of crude oil and natural gas
imports;


·
            the
      availability, proximity and cost of adequate pipeline and other
      transportation facilities;


·
            the
      success of efforts to market competitive fuels, such as coal and nuclear
      energy and the growth and/or success of alternative energy sources such as
      wind power;


·
            the
      effect of United States and state regulation of production, refining,
      transportation and sales;


·
            other
      matters affecting the availability of a ready market, such as fluctuating
      supply and demand; and


·
            general
      economic conditions in the United States and around the
    world.





The
supply and demand balance of crude oil and natural gas in world markets has
caused significant variations in the prices of these products over recent
years.  The North American Free Trade Agreement eliminated trade and
investment barriers between the United States, Canada, and Mexico, resulting in
increased foreign competition for domestic natural gas
production.  New pipeline projects recently approved by, or presently
pending before, FERC, as well as nondiscriminatory access requirements could
further substantially increase the availability of gas imports to certain U.S.
markets.  Such imports could have an adverse effect on both the price
and volume of natural gas sales from Partnership wells.





Members
of the Organization of Petroleum Exporting Countries (OPEC) establish prices and
production quotas for petroleum products from time to time with the intent of
affecting the global supply of crude oil and reducing, increasing or maintaining
certain price levels.  Reef is unable to predict what effect, if any,
such actions will have on the amount of or the prices received for crude oil
produced and sold from the Partnership's wells.





In
several initiatives, FERC has required pipelines to develop electronic
communication and to provide standardized access via the Internet to information
concerning capacity and prices on a nationwide basis, so as to create a national
market.  Parallel developments toward an electronic marketplace for
electric power, mandated by FERC, are serving to create multi-national markets
for energy products generally.  These systems will allow rapid
consummation of natural gas transactions.  Although this system may
initially lower prices due to increased competition, it is anticipated to expand
natural gas markets and to improve their reliability.

Regulation





The
Partnership's operations will be affected from time to time in varying degrees
by domestic and foreign political developments, and by federal and state laws
and regulations.





Regulation of Oil & Gas
Activities.  In most areas of operations within the United
States the production of crude oil and natural gas is regulated by state
agencies that set allowable rates of production and otherwise control the
conduct of oil and gas operations. Operators of oil and gas properties are
required to have a number of permits to operate such properties, including
operator permits and permits to dispose of salt water. RELP possesses all
material requisite permits required by the states and other local authorities in
areas where it operates properties.  States control production through
regulations that establish the spacing of wells or limit the number of days in a
given month a well can produce.  In addition, under federal law,
operators of oil and gas properties are required to possess certain certificates
and permits such as hazardous materials certificates, which RELP has
obtained.





Environmental
Matters.  The Partnership's drilling and production operations
are also subject to environmental protection regulations established by federal,
state, and local agencies that may necessitate significant capital outlays that,
in turn, would materially affect the financial position and business operations
of the Partnership. These regulations, enacted to protect against waste,
conserve natural resources and prevent pollution, could necessitate spending
funds on environmental protection measures, rather than on drilling operations.
If any penalties or prohibitions were imposed on the Partnership for violating
such regulations, the Partnership's operations could be adversely
affected.





Climate Change Legislation and
Greenhouse Gas Regulation.Studies in recent years have indicated that
emissions of certain gases may be contributing to warming of the Earth’s
atmosphere. Many nations have agreed to limit emissions of greenhouse gases
(GHGs) pursuant to the United Nations Framework Convention on Climate Change,
and the Kyoto Protocol. Methane, a primary component of natural gas, and carbon
dioxide, a byproduct of the burning of crude oil, natural gas, and refined
petroleum products, are considered GHGs regulated by the Kyoto Protocol.
Although the United States is currently not participating in the Kyoto Protocol,
several states have adopted legislation and regulations to reduce emissions of
GHGs. Restrictions on emissions of methane or carbon dioxide that may be imposed
in various states could adversely affect our operations and demand for crude oil
and natural gas. On December 7, 2009, the Environmental Protection Agency (EPA)
issued a finding that serves as the foundation under the Clean Air Act to issue
rules that would result in federal GHGs regulations and emissions limits under
the Clean Air Act, even without Congressional action. On September 29, 2009, the
EPA also issued a GHG monitoring and reporting rule that requires certain
parties, including participants in the oil and gas industry, to monitor and
report their GHG emissions, including methane and carbon dioxide, to the EPA.
The emissions will be published on a register to be made available on the
Internet. These regulations may apply to our operations. The EPA has proposed
two other rules that would regulate GHGs, one of which would regulate GHGs from
stationary sources, and may affect the oil and gas exploration and production
industry and the pipeline industry. The EPA’s finding, the GHG reporting rule,
and the proposed rules to regulate the emissions of GHGs would result in federal
regulation of carbon dioxide emissions and other GHGs, and may affect the
outcome of other climate change lawsuits pending in United States federal courts
in a manner unfavorable to the oil and gas industry.





Natural Gas Transportation and
Pricing.  FERC regulates the rates for interstate
transportation of natural gas as well as the terms for access to natural gas
pipeline capacity. Pursuant to the Wellhead Decontrol Act of 1989, however, FERC
may not regulate the price of natural gas. Such deregulated natural gas
production may be sold at market prices determined by supply and demand, Btu
content, pressure, location of wells, and other factors. Reef anticipates that
all of the natural gas produced by the Partnership's wells will be considered
price-decontrolled natural gas and that the Partnership's natural gas will be
sold at fair market value.  However, while sales by producers of
natural gas can currently be made at unregulated market prices, Congress could
reenact price controls in the future.





Proposed
Regulation.Various legislative proposals are being considered in
Congress and in the legislatures of various states, which, if enacted, may
significantly and adversely affect the petroleum and gas industries. Such
proposals involve, among other things, the imposition of price controls on all
categories of natural gas production, the imposition of land use controls, such
as prohibiting drilling activities on certain federal and state lands in
protected areas, as well as other measures. At the present time, it is
impossible to predict what proposals, if any, will actually be enacted by
Congress or the various state legislatures and what effect, if any, such
proposals will have on the Partnership's operations.


7





Employees





The
Partnership has no employees, and is managed by its managing general partner,
Reef. RELP employs a staff including geologists, petroleum engineers, landmen,
and accounting personnel who administer all of the Partnership’s operations. The
Partnership reimburses RELP for technical and administrative services at
cost.  See "Item 11- Executive Compensation."

            RISK
      FACTORS





Our
business activities are subject to certain risks and hazards, including the
risks discussed below. If any of these events should occur, it could materially
and adversely affect our business, financial condition, cash flow, or results of
operations. The risks below are not the only risks we face. We may experience
additional risks and uncertainties not currently known to us or, as a result of
developments occurring in the future, conditions that we currently deem to be
immaterial may also materially and adversely affect our business, financial
condition, cash flow, and results of operations.  Consequently, you
should not consider this list to be a complete statement of all of our potential
risks or uncertainties.

Crude
oil and natural gas prices are volatile, and fluctuate due to a number of
factors outside of our control.





The
financial condition, results of operations, and the carrying value of our oil
and gas properties depend primarily upon the prices received for our crude oil
and natural gas production. Crude oil and natural gas prices historically have
been volatile and likely will continue to be volatile given current geopolitical
conditions. Cash flow from operations is highly dependent upon the sales prices
received from crude oil and natural gas production. The prices for crude oil and
natural gas are subject to a variety of factors beyond our control. These
factors include:





·
            the
      domestic and foreign supply of crude oil and natural gas; consumer demand
      for crude oil and natural gas, and market expectations regarding supply
      and demand;


·
            the
      ability of the members of  OPEC to agree to and maintain crude
      oil price and production controls;


·
            domestic
      government regulations and taxes;


·
            the
      price and availability of foreign exports and alternative fuel
      sources;


·
            weather
      conditions, including hurricanes and tropical storms in and around the
      Gulf of Mexico;


·
            political
      conditions in crude oil and  natural gas producing regions,
      including the Middle East, Nigeria, and Venezuela;
  and


·
            domestic
      and worldwide economic conditions.





These
factors and the volatility of the energy markets make it extremely difficult to
predict price movements. Also, crude oil and natural gas prices do not
necessarily move in tandem. Declines in crude oil and natural gas prices would
not only reduce revenues and cash flow available for distributions to partners,
but could reduce the amount of crude oil and natural gas that can be
economically produced from successful wells drilled by the Partnership, and,
therefore, have an adverse effect upon financial condition, results of
operations, crude oil and natural gas reserves, and the carrying value of the
Partnership’s oil and gas properties. Approximately 69.2% of the Partnership’s
estimated proved reserves at December 31, 2009 were natural gas, and, as a
result, financial results are more sensitive to fluctuations in natural gas
prices.





The
Partnership, while not prohibited from engaging in commodity trading or hedging
activities in an effort to reduce exposure to short-term fluctuations in the
price of crude oil and natural gas, has not engaged in such activities.
Accordingly, the Partnership is at risk for the volatility in crude oil and
natural gas prices, and the level of commodity prices has a significant impact
upon the Partnership’s results of operations.





Oil
and gas well drilling is a speculative activity involving numerous risks and
substantial and uncertain costs which could adversely affect the
Partnership.





Drilling
oil and gas wells involves numerous risks, including the risk that no
commercially productive crude oil and/or natural gas reserves will be
discovered. There can be no assurance that wells drilled by the Partnership will
be productive or recover all or any portion of the investment in such wells.
Drilling and completion costs are substantial and uncertain, and drilling
operations may be curtailed, delayed, or cancelled due to a variety of factors
beyond our control, including shortages or delays in the availability of
drilling rigs and crews, unexpected drilling conditions, title problems,
pressure or irregularities in formations, equipment failures or accidents,
adverse weather conditions, and compliance with environmental and other
governmental regulations. Our drilling activities may not be successful and, if
unsuccessful, will have an adverse effect on the Partnership’s results of
operations and cash flow available for distribution to the
partners.





The
recent global economic downturn could have a material adverse impact on our
financial position, results of operations and cash flows.





The oil
and gas industry is cyclical and tends to reflect general economic conditions.
The United States and other countries around the world have experienced an
economic downturn which could impact the industry in 2010 and beyond. The
economic downturn has had an adverse impact on demand and pricing for crude oil
and natural gas. A continuation of the economic downturn could have a further
negative impact on crude oil and natural gas prices. The Partnership’s operating
cash flows and profitability will be significantly affected by declining crude
oil and natural gas prices. Further declines in crude oil and natural gas prices
may also impact the value of our crude oil and natural gas reserves, which could
result in future impairment charges to reduce the carrying value of the
Partnership’s oil and gas properties.


9





We
are subject to substantial operating risks that may adversely affect the results
of operations.





There are
numerous hazards involved in the drilling and operation of oil and gas wells,
including blowouts involving possible damages to property and third parties,
bodily injuries, mechanical failures, explosions, uncontrollable flows of crude
oil, natural gas or well fluids, fires, formations with abnormal pressure,
pollution, releases of toxic gas and other environmental hazards and risks. The
Partnership could suffer substantial losses as a result of any of these risks.
The Partnership is not fully insured against all risks inherent to the oil and
gas business. Uninsured liabilities would reduce the funds available to the
Partnership, may result in the loss of Partnership properties and may create
liability for the general partners. Although the Partnership maintains insurance
coverage in amounts Reef deems appropriate, it is possible that insurance
coverage may be insufficient. In that case Partnership assets may have to be
sold to pay personal injury and property claims and the cost of controlling
blowouts or replacing damaged equipment rather than for drilling
activities.





We
cannot control activities on non-operated properties.





The
Partnership has limited ability to exercise influence over and control the risks
associated with operations on properties not operated by RELP. The failure of an
operator of our wells to adequately perform operations, an operator’s breach of
the applicable agreements, or an operator’s failure to act in ways that are in
our best interest could reduce our production and revenues. The success and
timing of drilling and development activities on properties operated by others
depends upon a number of factors outside of our control, including the
operator’s





·
            timing
      and amount of capital expenditures;


·
            expertise
      and financial resources;


·
            inclusion
      of other participants in drilling wells;
and


·
            use
      of technology.





In
addition, the Partnership could be held liable for the joint interest
obligations of other working interest owners, such as nonpayment of costs and
liabilities arising from the actions of the other working interest owners. Full
development of prospects may be jeopardized in the event other working interest
owners cannot pay their share of drilling and completion costs.





Crude
oil and natural gas reserve data are estimates based upon assumptions that may
be inaccurate and existing economic and operating conditions that may differ
from future economic and operating conditions.





Securities
and Exchange Commission (SEC) rules require the Partnership to present annual
estimates of reserves. Reservoir engineering is a subjective process of
estimating the recovery from underground accumulations of crude oil and natural
gas that cannot be precisely measured, and is based upon assumptions that may
vary considerably from actual results. Accordingly, reserve estimates may be
subject to upward or downward adjustments. Actual production, revenues and
expenditures with respect to reserves will likely vary from estimates, and such
variances could be material.





You
should not assume the present value of future net cash flows referred to in this
Annual Report to be the current market value of our estimated crude oil and
natural gas reserves. The estimated discounted future net cash flows from our
proved reserves as of December 31, 2009 are based upon the 12-month un-weighted
arithmetic average of the first-day-of-the-month prices and costs in effect when
the estimate is made. Actual current prices, as well as future prices and costs,
may be materially higher or lower. Further, actual future net cash flows will be
affected by factors such as the amount and timing of actual production, supply
and demand for crude oil and natural gas, and changes in governmental
regulations and tax rates.





The
Partnership Agreement limits Reef's liability to each partner and the
Partnership and requires the Partnership to indemnify Reef against certain
losses.





Reef will
have no liability to the Partnership or to any partner for any loss suffered by
the Partnership, and will be indemnified by the Partnership against loss
sustained by it in connection with the Partnership if:





·
            Reef
      determines in good faith that its action was in the best interest of the
      Partnership;


10


·
            Reef
      was acting on behalf of or performing services for the Partnership;
      and


·
            Reef's
      actions did not constitute negligence or
  misconduct.





Drilling
exploratory wells is riskier than drilling developmental wells.





Drilling
exploratory wells involves greater risks of dry holes and loss of the partners'
investment than the drilling of developmental wells.  Drilling
developmental wells generally involves less risk of dry holes, although
sometimes developmental acreage is more expensive and subject to greater
royalties and other burdens on production. The Partnership purchased working
interests in fourteen exploratory prospects upon which sixteen exploratory and
eight developmental wells were drilled. Eight exploratory wells were successful
and eight exploratory wells were unsuccessful. Seven developmental wells were
successful and one was unsuccessful. Three of the successful exploratory wells
have ceased production as of December 31, 2009.





The
production and producing life of Partnership wells is uncertain.





Production
will decline. It is not possible to predict the life and production of any well.
The actual life could differ from that which is anticipated. Sufficient crude
oil or natural gas may not be produced for a partner to receive a profit or even
to recover his initial investment. In addition, production from the
Partnership's oil and gas wells, if any, will decline over time, and does not
indicate any consistent level of future production. This production decline may
be rapid and irregular when compared to a well's initial
production.





Extreme
weather conditions may adversely affect production operations and partner
distributions.





The
Partnership conducts operations in the Gulf of Mexico and in coastal regions of
Louisiana and Texas. This area is susceptible to extreme weather conditions,
especially those associated with hurricanes. In the event of a hurricane and
related storm activity, such as windstorms, storm surges, floods and tornados,
Partnership operations in the region may be adversely affected. The occurrence
of a hurricane or other extreme weather may harm or delay the Partnership’s
operations or distribution of revenues, if any.





Our
dependence on third parties for the processing and transportation of crude oil
and natural gas may adversely affect the Partnership’s revenues and,
consequently, the distribution of net cash flows to investor partners.





We rely
on third parties to process and transport the crude oil and natural gas produced
by the Partnership’s successful wells. In the event a third party upon whom we
rely is unable to provide transportation or processing services, and another
third party is unavailable to provide such services, the Partnership may have to
temporarily shut-in successful wells, and revenues to the Partnership and
distributions to investor partners related to those wells may be
delayed.





We
face strong competition within the energy industry.





The oil
and gas industry is highly competitive. Competition is encountered in all
aspects of Partnership operations, including the requisition of drilling and
service contractors. Many of our competitors are larger, well-established
companies with substantially larger operating staffs and greater capital
resources than those of the Partnership, Reef and its affiliates. We may not be
able to conduct our operations successfully, obtain drilling and service
contractors, consummate transactions, and obtain technical, managerial and other
professional personnel in this highly competitive environment. Specifically,
larger competitors may be able to pay more for competent personnel than the
Partnership, Reef and its affiliates. In addition, such competitors may be able
to expend greater resources on the existing and changing technologies that will
be increasingly important to success. Such competitors may also be in a better
position to secure drilling and oilfield services, as well as equipment, more
timely or on more favorable terms. Finally, oil and gas producers are
increasingly facing competition from providers of non-fossil energy, and
government policy may favor those competitors in the future.


11





The
Partnership has limited external sources of funds, which could result in a
shortage of working capital.





The
Partnership expended funds in excess of the previously raised capital in
connection with the drilling and completion of wells and acquisition of the
prospects during the drilling phase of operations. These excess expenditures
have been recovered through reductions in Partnership
distributions.  The Partnership only has nominal funds available for
Partnership purposes until there are revenues from Partnership operations. Any
future requirement for additional funding for drilling will have to come, if at
all, from the Partnership's revenues or from borrowings. Reef cannot assure the
partners that Partnership operations will be sufficient to provide the
Partnership with necessary additional funding.  Reef cannot assure the
partners that the Partnership will be able to borrow funds from third parties on
commercially reasonable terms or at all.





The
Partnership may incur liability for liens against its
subcontractors.





Although
Reef will try to determine the financial condition of nonaffiliated
subcontractors, if subcontractors fail to timely pay for materials and services,
the properties of the Partnership could be subject to materialmen's and
workmen's liens.  In that event, the Partnership could incur excess
costs in discharging such liens.





Other
partnerships Reef sponsors will compete with the Partnership for equipment,
contractors, and personnel.





Reef
plans to offer interests in other partnerships to be formed for substantially
the same purposes as those of the Partnership. Therefore, a number of
partnerships with unexpended capital funds, including those partnerships to be
formed in future oil and gas programs sponsored by Reef, may exist at the same
time.  Due to competition among the partnerships for equipment,
contractors, and Reef's personnel, the fact that other partnerships organized by
Reef and its affiliates may still be purchasing prospects and drilling and
completing wells when the Partnership is attempting to drill and complete wells
on its prospects may make such activities of the Partnership more
difficult.

Drilling
Activities and Productive Wells





Partnership
prospects are located onshore in Texas, Louisiana, Oklahoma, and New Mexico and
offshore in U.S. coastal waters in the Gulf of Mexico. The Partnership purchased
working interests in twenty developmental prospects. The Partnership drilled
eight successful developmental wells on eight developmental prospects located in
Acadia Parish, Louisiana, Pittsburg County, Oklahoma, and Palo Pinto, Jackson,
Harris, Galveston, and Lavaca (2 prospects) County, Texas. One well located in
Lavaca County, Texas ceased production during 2007, two wells located in Acadia
Parish, Louisiana and Jackson County, Texas ceased production during 2008, and
two wells located in Lavaca and Palo Pinto County, Texas ceased production
during 2009. The Partnership drilled eleven unsuccessful developmental wells on
eleven developmental prospects located in West Baton Rouge, Acadia, Calcasieu,
and Cameron Parish, Louisiana, and in Hardin, Upton, Ector, Jefferson, Lavaca,
Reeves, and Dawson County, Texas.





The
Partnership participated in the drilling of eight developmental wells on the
Sand Dunes prospect located in Eddy County, New Mexico during the fourth quarter
of 2007 and the first quarter of 2008. Initial testing confirmed the presence of
crude oil and natural gas in all eight wells. However, the field was temporarily
shut-in because of the lack of electric service and because of the high cost of
trucking offsite the salt water volumes associated with the production of the
crude oil and natural gas from the wells. Electrical service to the eight Sand
Dunes wells was connected in September 2008. Based upon initial testing, larger
bottom hole pumps were placed below the well perforations in three of the wells
and testing was resumed in late September 2008 to determine the three wells’
commercial productivity. Water continued to be trucked offsite, and RELP applied
for and received a permit which would allow for the conversion of one of the
existing eight Sand Dunes wells into a water disposal well. RELP also explored
the possibility of drilling a ninth well as a salt water disposal well for the
field. Testing results on two of the three wells were positive, and salt water
production volumes declined as a result of pumping off the wells using the
larger bottom hole pumps. However, the price of crude oil also declined at a
rapid rate while testing was being conducted. In late December 2008, two of the
three testing wells were shut-in again. Crude oil prices continued declining to
a level below $40 per barrel. In February 2009, following a mechanical failure
in the third testing well, RELP, as operator, shut-in the field. The eight wells
cannot be commercially productive without efficient salt water disposal
capabilities, and none of the options regarding salt water disposal were
economically viable at first quarter 2009 commodity prices. As a result, as of
December 31, 2008, the eight Sand Dunes wells were classified as unsuccessful,
and no crude oil and natural gas reserves for these wells were included in the
December 31, 2008 reserve information presented in this Annual
Report.


12





Beginning
with March 2009, oil sales prices increased from levels below $40 per barrel to
between $60 and $70 per barrel. As a result of this increase in prices, in
October 2009, Reef approved the conversion of one of the eight wells on the Sand
Dunes development prospect located in Eddy County, New Mexico to a salt water
disposal well. The conversion work began in March 2010. Upon conversion of this
well to a salt water disposal well, three of the current Sand Dunes wells are
expected to be placed on full time production during the second quarter of 2010.
RELP believes, based upon testing already performed, that the disposal capacity
of the well to be converted will be such that only three Sand Dunes wells can be
placed on full time production. However, if possible, additional wells may be
placed on production. RELP will determine what actions to take regarding the
other Sand Dunes wells after a period of evaluation of this initial conversion.
The estimated cost of the well conversion to this Partnership is expected to be
approximately $79,290. This cost will be paid for by the Partnership by
retaining a portion of the funds normally paid out in distributions to the
partners. There are 5,330 BBL of crude oil and 8,830 MCF of natural gas reserves
for the three wells expected to be placed on full time production included in
the December 31, 2009 reserve information presented in this Annual
Report.





The
Partnership also has interests in unproved property consisting of un-drilled
leasehold interests (11 potential drilling locations) in the Sand Dunes
prospect. The Partnership fully impaired this unproved property during the
fourth quarter of 2008 based upon the eight already drilled wells being
classified as unsuccessful at December 31, 2008. The Partnership currently has
no plans to conduct any drilling operations on this acreage.





The
Partnership purchased working interests in fourteen exploratory prospects, upon
which a total of sixteen exploratory and eight developmental wells were drilled.
The Partnership drilled eight successful exploratory wells, one unsuccessful
exploratory well, seven successful developmental wells, and one unsuccessful
developmental well on seven exploratory prospects located in Terrebonne and St.
Martin Parish, Louisiana, Sterling, Nueces (2 prospects) and Live Oak County,
Texas, and offshore in U.S. Coastal waters in the Gulf of Mexico. The
Partnership drilled seven unsuccessful exploratory wells on seven exploratory
prospects located in West Baton Rouge, Beauregard, and Cameron Parish,
Louisiana, Brazoria, Lavaca, and San Patricio County, Texas, and offshore in
U.S. Coastal waters in the Gulf of Mexico. Of the fifteen successful wells,
three wells located in St. Martin and Terrebonne Parish, Louisiana and in Live
Oak County, Texas ceased production in 2006 and 2007.





Fifteen
of the twenty-three successful wells in which the Partnership participated in
drilling are currently productive.





Proved
Crude Oil and Natural Gas Reserves





In
January 2009, the SEC adopted new rules related to modernizing reserve
calculation and disclosure requirements for oil and gas companies, which became
effective prospectively for annual reporting periods ending on or after December
31, 2009.  In addition to expanding the definition and disclosure
requirements for crude oil and natural gas reserves, the new rule changes the
requirements for determining quantities of crude oil and natural gas reserves.
The new rule requires disclosure of crude oil and natural gas proved reserves by
significant geographic area, using the un-weighted arithmetic average of
first-day-of-the-month commodity prices over the preceding 12-month period,
rather than end-of-period prices, and allows the use of reliable technologies to
estimate proved crude oil and natural gas reserves, if those technologies have
been demonstrated to result in reliable conclusions about reserves volumes.
Reserve and related information for 2009 is presented consistent with the
requirements of the new rule. The new rule does not allow prior-year reserve
information to be restated, so all information related to periods prior to 2009
is presented consistent with prior SEC rules for the estimation of proved
reserves. The effect of applying the new definition of reliable technology and
other non-price related aspects of the updated rules did not significantly
impact 2009 net proved reserve volumes.  All of the Partnership’s
reserves are located in the United States.


13





The
estimated net proved crude oil and natural gas reserves at December 31, 2009,
2008, and 2007 are summarized below. The estimated quantities of proved crude
oil and natural gas reserves discussed in this section include only the amounts
which the Partnership reasonably expects to recover in the future from known oil
and gas reservoirs under the current economic and operating conditions. Proved
reserves include only quantities that the Partnership expects to recover
commercially using current prices, costs, existing regulatory practices, and
technology. Therefore, any changes in future prices, costs, regulations,
technology or other unforeseen factors could materially increase or decrease the
proved reserve estimates.

Qualifications
of Technical Persons and Internal Controls Over the Reserves Estimation
Process





The
Partnership used an independent petroleum consulting company, Forrest A. Garb
& Associates, Inc., (FGA) of Dallas, Texas, to prepare its December 31, 2009
estimates of net proved crude oil and natural gas reserves.  FGA
estimated reserves for all of our properties as of December 31, 2009. The
technical personnel responsible for preparing the reserve estimates at FGA meet
the requirements regarding qualifications, independence, objectivity, and
confidentiality set forth in the Standards Pertaining to the Estimating and
Auditing of Oil and Gas Reserves Information promulgated by the Society of
Petroleum Engineers. FGA is an independent firm of petroleum engineers and
geologists. They do not own an interest in any of our properties, and are not
employed on a contingent fee basis. FGA’s report was developed utilizing state
reporting records and published production data purchased from third parties,
and data provided by Reef.  Their reserve summary, which contains
further discussions of the reserve estimates and evaluations, as well as the
qualifications of FGA’s technical personnel responsible for overseeing their
estimates and evaluations, is included as Exhibit 99.1 to this Annual
Report.





The
Partnership used an independent petroleum engineer, Gleason Engineering, of
Arlington, Texas, to prepare its December 31, 2008 and 2007 estimates of net
proved crude oil and natural gas reserves.





Reef’s
policies and practices regarding internal controls over the recording of
reserves are structured to objectively and accurately estimate oil and gas
reserve quantities and present values in compliance with SEC regulations and US
GAAP.





Reef
maintains a staff of petroleum engineers who work with FGA. Our accounting
department accumulates historical production and pricing data and lease
operating expenses for our wells, as well as the percentage interest owned by
the Partnership, which is reviewed by our engineering personnel. Reserve
estimates are prepared by FGA. Our engineering personnel meet regularly
with FGA’s
representative to review properties and discuss methods and assumptions used in
the preparation of their estimates. Mr. Byron H. (Howard) Dean, Manager –
Acquisitions and Divestitures of RELP, is the petroleum engineer primarily
responsible for overseeing the preparation of reserve estimates by FGA. Mr. Dean
is a registered petroleum engineer with over thirty years of industry experience
in oil and gas operations and reservoir engineering. He is an active member of
the Society of Petroleum Engineers and the Society of Petroleum Evaluation
Engineers. Any significant reserve changes are approved by Mr. Dean and Mr.
Michael J. Mauceli, Chief Executive Officer of RELP.

Title
to Properties





The
Partnership's interests in producing and non-producing acreage are in the form
of assigned direct interests in leases held by the Partnership or by Reef on
behalf of the Partnership. Such properties are subject to customary royalty
interests and could be subject to liens incident to operating agreements, liens
for current taxes and overriding royalty interests and other
burdens.  The Partnership believes that none of these burdens will
materially interfere with the use of such properties in the operation of the
Partnership's business and that it has or will obtain satisfactory title to all
of its leases. Title will be held by the Partnership or by Reef on behalf of the
Partnership.

              MARKET
      FOR REGISTRANT'S COMMON EQUITY, RELATED STOCKHOLDER MATTERS AND ISSUER
      PURCHASES OF EQUITY
SECURITIES





As of
December 31, 2009, the Partnership had one managing general partner, and 1,150
investor limited partners. Pursuant to the Partnership Agreement of the
Partnership, all general partner units held by investor partners were converted
into limited partner units during the 3rd quarter
of 2008. Reef holds a total of 75.363 general partner units and the investor
partners hold 1,431.897 limited partner units. No established trading market
exists for the units.





Cash
which, in the sole judgment of the managing general partner, is not required to
meet the Partnership’s obligations is distributed to the partners at least
quarterly in accordance with the Partnership Agreement. The Partnership has made
monthly cash distributions to the partners of interest income and crude oil and
natural gas sales revenues, less operating, general and administrative, and
other costs since December 2005.  Cash distributions are distributed
15.45% to the managing general partner (based upon the 11% interest not
represented by units and the 4.45% interest represented by Partnership units)
and 84.55% to investor partners.





Investor
limited partner interests are transferable, subject to certain restrictions
contained in the Partnership Agreement; however, no assignee of a unit in the
Partnership can become a substituted partner without the written consent of both
the transferor and Reef.





The
Partnership has adopted a unit repurchase program. Under the terms of the
program, the managing general partner is obligated to purchase up to 5% of the
units in the Partnership per year during the period set forth in the Partnership
Agreement, unless changes in oil and gas pricing meet certain criteria specified
in the prospectus supplement, dated July 8, 2005. However, the managing general
partner’s obligation to purchase units is limited to $500,000 per year in the
aggregate for all partnerships previously or subsequently organized by the
managing general partner or its affiliates. The Partnership did not repurchase
any units in 2009.





Use
of Proceeds





In
connection with the Registration Statement filed on form S-1 (No. 333-122935)
and declared effective July 7, 2005, Reef filed a final prospectus for the
Program on July 8, 2005. On July 8, 2005, Reef filed a prospectus supplement
describing the Partnership and commenced the offering of units in the
Partnership. All sales of Partnership units were made through the Program's
dealer-manager, Reef Securities, Inc., and a number of soliciting dealers. The
offering terminated October 31, 2005. Under the terms of the offering, a minimum
of 40 Partnership units at a price of $25,000 per unit were required to be sold
in order to form the Partnership. Upon meeting this requirement, the Partnership
was formed on July 18, 2005.

The
Partnership registered a total of 400 units of limited partner interests and
1,600 units of general partner interests. The aggregate offering amount
registered was $50,000,000. During the offering period that terminated on
October 31, 2005, the Partnership sold 1,431.897 units to investor partners,
consisting of 241.336 units of limited partner interest and 1,190.561 units of
additional general partner interest. Reef purchased 75.363 general partner
units, equaling 5.00% of the total Partnership units sold. The Partnership did
not sell the remaining registered units. Total offering proceeds were
$37,398,898. Reef also contributes 1% of all leasehold, drilling, and completion
costs as incurred. At December 31, 2009, Reef had contributed $316,361 in
connection with this obligation.





All units
except those purchased by Reef paid a 15% management fee to Reef to pay for the
Partnership organization and offering costs, including sales commissions. These
costs totaled $5,369,615, leaving capital contributions of $32,345,644 available
for Partnership oil and gas operations. As of December 31, 2009, the Partnership
had expended $33,408,778 on property acquisitions and $138,317 on general and
administrative expenses.  At December 31, 2009, the Partnership had
recovered the $1,201,451 deficit through reductions in partner
distributions.

ITEM
      7.
            MANAGEMENT’S
      DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF
      OPERATIONS





The
following discussion will assist you in understanding the Partnership’s
financial position, liquidity, and results of operations. The information should
be read in conjunction with the audited financial statements and notes to
financial statements contained herein. The discussion contains historical and
forward-looking information.





For a
discussion of risk factors that could impact the Partnership’s financial
results, please see Item 1A of this Annual Report.





Critical
Accounting Policies





The
preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America requires us to make estimates
and assumptions that can affect the reporting of assets, liabilities, equity,
revenues, and expenses. We base our estimates on historical experience and
various other assumptions that are believed to be reasonable under the
circumstances. Actual results may differ from these estimates under different
assumptions or conditions. We are also required to select among alternative
acceptable accounting policies. See Note 2 to the financial statements for a
complete list of significant accounting policies.





Oil
and Gas Properties





The
Partnership follows the full cost method of accounting for oil and gas
properties. Under this method, all direct costs and certain indirect costs
associated with acquisition of properties and successful as well as unsuccessful
exploration and development activities are capitalized. Depreciation, depletion,
and amortization of capitalized oil and gas properties and estimated future
development costs, excluding unproved properties, are based on the
unit-of-production method using estimated proved reserves.  For these
purposes, proved natural gas reserves are converted to equivalent barrels of
crude oil at a rate of 6 Mcf to 1 Bbl.





In
applying the full cost method at December 31, 2009, we perform a quarterly
ceiling test on the capitalized costs of oil and gas properties, whereby the
capitalized costs of oil and gas properties are limited to the sum of the
estimated future net revenues from proved reserves using prices that are the
12-month un-weighted arithmetic average of the first-day-of-the-month price for
crude oil and natural gas held constant and discounted at 10%, plus the lower of
cost or estimated fair value of  unproved properties, if any, for
2009. If capitalized costs exceed the ceiling, an impairment loss is recognized
for the amount by which the capitalized costs exceed the ceiling, and is shown
as a reduction of oil and gas properties and as property impairment expense on
the Partnership’s statement of operations.  No gain or loss is
recognized upon sale or disposition of oil and gas properties, unless such a
sale would significantly alter the rate of depletion and amortization. During
the years ended December 31, 2009, 2008 and 2007, the Partnership recognized
property impairment expense of proved properties totaling $4,629,688, $0, and
$9,466,246, respectively.


17


Unproved
properties consist of undeveloped leasehold interest. Investments in unproved
properties are not depleted pending determination of the existence of proved
reserves. Unproved properties are assessed for impairment quarterly as of the
balance sheet date by considering the primary lease term, the holding period of
the properties, geologic data obtained relating to the properties, and other
drilling activity in the immediate area of the properties. Any impairment
resulting from this quarterly assessment is reported as property impairment
expense in the current period, as appropriate. During the year ended December
31, 2008, the Partnership fully impaired its unproved properties by recognizing
$172,930 of property impairment expense.





The
estimate of proved crude oil and natural gas reserves used to determine property
impairment expense, and also utilized in the Partnership’s disclosures of
supplemental information regarding oil and gas producing activities, including
the standardized measure of discounted cash flows, was prepared by an
independent petroleum engineer at  December 31, 2009, 2008 and 2007,
utilizing prices and costs as promulgated by the SEC. Reservoir engineering is a
subjective and inexact process of estimating underground accumulations of crude
oil and natural gas that cannot be measured in an exact manner, and is based
upon assumptions that may vary considerably from actual results. Accordingly,
reserve estimates may be subject to upward or downward adjustments. Actual
production, revenues and expenditures with respect to reserves will likely vary
from estimates, and such variances could be material.





The
determination of depreciation, depletion and amortization expense recognized in
the financial statements is also dependent upon the estimates of proved crude
oil and natural gas reserves and is computed using the units-of-production
method based upon this estimate of proved reserves. During the years ended
December 31, 2009, 2008 and 2007, the Partnership had depreciation, depletion,
and amortization expense totaling $2,343,937, $2,320,505, and $2,468,104,
respectively.





Asset
retirement costs and liabilities associated with future site restoration and
abandonment of long-lived assets are initially measured at fair value which
approximates the cost a third party would incur in performing the tasks
necessary to retire such assets. The fair value is recognized in the financial
statements as the present value of expected future cash expenditures for site
restoration and abandonment. Subsequent to the initial measurement, the effect
of the passage of time on the liability for the net asset retirement obligation
(accretion expense) and the amortization of the asset retirement cost are
recognized in the results of operations. During the years ended December 31,
2009, 2008 and 2007, the Partnership recognized $0, $35,166, and $66,966 of
asset retirement obligations in connection with successful wells drilled by the
Partnership.





Recognition
of Revenue





The
Partnership has entered into sales contracts for disposition of its share of
crude oil and natural gas production from productive wells. Revenue is
recognized based upon the metered volumes delivered to those purchasers each
month. Any significant over or under balanced gas positions are disclosed in the
financial statements. As of December 31, 2009, 2008 and 2007, the Partnership
had no material gas imbalance positions.





Recently Adopted Accounting
Pronouncements





Modernization
of Oil and Gas Reporting





In
January 2009, the SEC adopted new rules related to modernizing reserve
calculation and disclosure requirements for oil and gas companies, which became
effective prospectively for annual reporting periods ending on or after December
31, 2009. In addition to expanding the definition and disclosure requirements
for crude oil and natural gas reserves, the new rule changes the requirements
for determining quantities of crude oil and natural gas reserves. The new rule
also changes certain accounting requirements under the full cost method of
accounting for oil and gas activities. The changes are designed to modernize the
requirements for the determination of crude oil and natural gas reserves,
aligning them with current practices and updating them for changes in
technology. The effect of applying the un-weighted arithmetic average of the
first-day-of-the-month commodity prices for the preceding 12-month period,
compared to the use of end-of-period prices and costs, decreased net proved
reserves by 5.1%. The standardized measure of discounted future net cash flows
for the year ended December 31, 2009 was lower by $2,019,550 as a result of
using the new rule as compared to amounts calculated using the previous rules.
The effect of applying the new rule resulted in additional depletion expense of
$15,483 and additional impairment expense of $1,503,338.

Accounting
Standards Codification




In
June 2009, the Financial Accounting Standards Board (FASB) issued guidance
on the accounting standards codification and the hierarchy of generally accepted
accounting principles. The accounting standards codification is intended to be
the source of authoritative US GAAP and reporting standards as issued by
the FASB. Its primary purpose is to improve clarity and use of existing
standards by grouping authoritative literature under common topics. The
accounting standards codification is effective for financial statements issued
for interim and annual periods ending after September 15, 2009. The
Partnership now describes the authoritative guidance used within the footnotes
but no longer uses numerical references. The accounting standards codification
does not change or alter existing US GAAP, and there is no expected impact
on the Partnership’s financial position, results of operations or cash
flows.





Fair
Value Measurement of Liabilities




In
August 2009, the FASB issued new guidance for the accounting for the fair
value measurement of liabilities.  The new guidance provides clarification
that in certain circumstances in which a quoted price in an active market for
the identical liability is not available, a company is required to measure fair
value using one or more of the following valuation techniques: the quoted price
of the identical liability when traded as an asset, the quoted prices for
similar liabilities or similar liabilities when traded as assets, and/or another
valuation technique that is consistent with the principles of fair value
measurements.  The new guidance is effective for interim and annual periods
beginning after August 27, 2009.  The Partnership does not
expect that the provisions of the new guidance will have a material
effect on its results of operations, financial position or
liquidity.





Subsequent
Events





In
May 2009, the FASB issued new guidance for accounting for subsequent
events.  This guidance established general standards of accounting for and
disclosure of events that occur after the balance sheet date but before
financial statements are issued or are available to be issued. This guidance is
effective for interim and annual reporting periods ending after June 15, 2009.
The Partnership adopted the provisions of this guidance for the period ended
June 30, 2009. In February 2010, the FASB issued an update to this guidance.
Among other provisions, this update provides that an entity that is a SEC filer
is not required to disclose the date through which subsequent events have been
evaluated. The Partnership adopted the provisions on its effective date of
February 24, 2010. There was no impact on the Partnership’s operating results,
financial position or cash flows.





Recognition
and Presentation of Other-Than-Temporary Impairments





In April
2009, the FASB issued new guidance related to the presentation and disclosure of
other-than-temporary impairments on debt and equity securities.  The
new guidance amends the other-than-temporary impairment guidance for debt
securities to make the guidance more operational and to improve the presentation
and disclosure of other-than-temporary impairments on debt and equity securities
in the financial statements.  The guidance does not amend existing
recognition and measurement guidance for equity securities, but does establish a
new method of recognizing and reporting for debt
securities.  Disclosure requirements for impaired debt and equity
securities have been expanded significantly and are now required quarterly, as
well as annually.  This guidance became effective for interim and
annual reporting periods ending after June 15, 2009.  Comparative
disclosures are required for periods ending after the initial
adoption.  This guidance did not have an impact on the Partnership’s
financial position, results of operations or cash flows.





Interim
Reporting of Fair Value of Financial Instruments





In
April 2009, the FASB issued new guidance related to the disclosure of the
fair value of financial instruments.  The new guidance amends SFAS No. 107,
“Disclosures about Fair Value of Financial Instruments,” to require disclosures
about fair value of financial instruments for interim reporting
periods.  The guidance also amends APB Opinion No. 28, “Interim
Financial Reporting,” to require those disclosures about the fair value of
financial instruments in summarized financial information at interim reporting
periods.  This guidance is effective for reporting periods ending
after June 15, 2009.  The adoption of this guidance did not have any
impact on the Partnership’s results of operations, cash flows, or financial
position.

Overview





Reef
Global Energy VI, L.P. is a Nevada limited partnership formed to acquire,
explore, develop, and produce crude oil, natural gas, and natural gas liquids
for the benefit of its investor partners. The Partnership's primary purposes are
to generate revenues from the production of crude oil and natural gas,
distribute cash flow to investors, and provide tax benefits to investors. The
majority of the Partnership’s proceeds have been used to purchase prospects and
drill oil and gas wells upon those prospects.





The
Partnership raised capital from the sale of Partnership units to investor
partners and Reef, and used those funds for the purchase of working interests in
prospects and for drilling and completion operations and administrative costs
during its drilling phase of operations. The Partnership did not borrow funds
during the drilling phase of operations, and interest income and crude oil and
natural gas revenues from successful wells, net of expenses, are being
distributed monthly to the partners. The Partnership is allowed to borrow funds
in accordance with the Partnership Agreement, or utilize cash flows from
successful wells in order to conduct further development upon prospects
initially purchased by and drilled on by the Partnership during the drilling
phase of operations. The Partnership completed its drilling phase of operations
during the first quarter of 2008. Subsequent to the original drilling phase of
operations, the Partnership drilled two additional exploratory wells on one of
the Partnerships’ prospects located in Live Oak County, Texas. An exploratory
well drilled during the third quarter of 2008 was successful and began
production operations in November of 2008. A second exploratory well drilled
during March 2009 was unsuccessful and was plugged and abandoned. The
Partnership utilized cash flow from existing wells by reducing distributions to
partners in the drilling of these two wells. The Partnership may conduct
additional drilling operations on its prospects in the future.





The
Partnership does not operate in any other industry segment. The Partnership
expended approximately $1,644,000 for the purchase of working interests in
twenty developmental prospects, and expended approximately $1,237,000 for the
purchase of working interests in fourteen exploratory prospects.  The
Partnership has twenty prospects in Texas, ten in Louisiana, one in Oklahoma,
and one in New Mexico, all of which are located onshore, and two prospects
located offshore in U.S. coastal waters in the Gulf of Mexico. The Partnership
has drilled thirty-five developmental and sixteen exploratory wells on these
prospects as of December 31, 2009. Forty-nine of these wells were drilled during
the Partnership’s drilling phase of operations, and two additional wells were
drilled subsequent to the completion of the Partnership’s drilling phase of
operations.  Four wells were drilled during 2005, twenty-seven were
drilled during 2006, fourteen were drilled during 2007, five were drilled during
2008, and one was drilled during 2009. The Partnership has drilled fifteen
successful developmental wells, of which ten are currently productive. The
Partnership drilled twenty unsuccessful developmental wells. The Partnership
drilled eight successful exploratory wells, of which five are currently
productive. The Partnership drilled eight unsuccessful exploratory
wells.





Should
the Partnership elect to borrow monies for additional development activity on
its prospects, it will be subject to the interest rate risk inherent in
borrowing activities. The Partnership is permitted but is not expected to engage
in commodity futures trading or hedging activities, and therefore is subject to
commodity price risk.   See "Item 7A - Quantitative And
Qualitative Disclosure About Market Risk."





Liquidity
and Capital Resources





The
Partnership was funded with initial capital contributions totaling $37,398,898.
Investor partners purchased 1,190.561 general partner units and 241.336 limited
partner units for $35,797,434. Reef purchased 75.363 general partner units, or
5% of the total units sold, for $1,601,464. As of December 31, 2009, Reef has
also contributed $316,361 in connection with its obligation to pay 1% of all
leasehold, drilling, and completion costs. Organization and offering costs
totaled $5,369,615, leaving capital contributions of $32,345,644 available for
Partnership activities. The Partnership was formed on July 18, 2005, and the
last partner was admitted to the Partnership on October 31,
2005.


20


The
Partnership did not borrow additional funds in accordance with limitations set
forth in the Partnership Agreement during the drilling phase of operations. The
Partnership expended $33,101,838 on the drilling of 49 wells and $138,317 on
general and administrative expenses during its initial drilling phase of
operations. The Partnership also expended $306,940 on the drilling of a
successful exploratory well in September 2008 and an unsuccessful exploratory
well in March 2009, subsequent to the completion of the Partnership’s drilling
phase. The $1,201,451 expended in excess of capital raised was recovered from
the cash flow from successful wells by reducing cash distributions to investor
partners. There are no plans to conduct any additional drilling on Partnership
prospects at this time; however, additional drilling activity is permitted on
the Partnership prospects.

The
Partnership had working capital of $816,754 at December 31, 2009. Subsequent to
expending the initial available Partnership capital contributions on prospect
acquisitions and drilling and completion costs of partnership wells, the
Partnership working capital consists primarily of cash flows from productive
properties utilized to pay cash distributions to investors.





Results
of Operations





Year
Ended December 31, 2009 compared to Year Ended December 31, 2008





The
Partnership had a net loss totaling $3,905,994 during 2009, compared to net
income totaling $4,448,003 during 2008. The decline in operating results is due
to two primary factors. First, the Partnership saw significant decreases in the
2009 average sales prices for its crude oil of 46.6% and natural gas of 57.3%
compared to 2008. Second, the Partnership had impairment of proved properties of
$4,629,688 and no impairment of unproved properties during 2009, compared to no
impairment of proved properties and $172,930 impairment of unproved properties
during 2008.





Impairment
of proved properties totaling $2,417,333 occurred during the first quarter of
2009, and was the result of significant declines in commodity prices. The
decline in commodity prices resulted in shorter estimated economic lives for
Partnership properties, which decreased both reserve estimates and the
corresponding future net revenues expected from Partnership
properties.   The estimated discounted future net cash flows of
the Partnership totaled $7,251,567 at March 31, 2009, compared to $10,651,949 at
December 31, 2008.  The Partnership took additional impairment of
proved properties of $709,017 during the third quarter of 2009, due to the
continuing decline in commodity prices.  The Partnership took another
significant impairment of proved properties of $1,503,338 during the fourth
quarter of 2009, due to the effect of applying the new rules regarding reserve
calculation and disclosures. See “Item 7 – Management’s Discussion and Analysis
of Financial Condition and Results of Operations – Recently Adopted Accounting
Pronouncements – Modernization of Oil and Gas Reporting” for more information
regarding the new rules.


21


At
December 31, 2009, the estimated discounted future net cash flows of the
Partnership totaled $3,600,860, compared to $10,651,949 at December 31, 2008.
Approximately $3.7 million of the reduction is the direct result of lower base
sales prices at December 31, 2009, which impacts the estimated economic life of
Partnership wells and estimated economic reserves to be produced from
Partnership wells. The base year end prices for natural gas used in the
Partnership’s reserve studies were $3.83 per MCF of natural gas at December 31,
2009, compared to $5.71 per MCF of natural gas at December 31, 2008. The prices
used at December 31, 2009 reflect the new rules regarding reserve calculation,
in which the prices are based on the un-weighted arithmetic average of the
first-day-of-the-month commodity prices over the preceding 12-month period and
current costs, compared to the end-of-period commodity prices and costs as used
in previous years.  See “Item 7 – Management’s Discussion and Analysis
of Financial Condition and Results of Operations – Recently Adopted Accounting
Pronouncements – Modernization of Oil and Gas Reporting” for more information
regarding the new rules. As approximately 69.2% of the Partnership’s estimated
proved reserves at December 31, 2009 were natural gas, financial results are
sensitive to fluctuations in natural gas prices.  See “Item 7A –
Quantitative and Qualitative Disclosure About Market Risk.” As such, the
Partnership recorded impairment of proved properties during 2009 of
$4,629,688.





During
2009, two Partnership wells accounted for 73.3% of Partnership crude oil and
natural gas sales revenues, and these two wells account for 65.0% of total
Partnership reserves at December 31, 2009.





Production
expenses decreased during 2009 primarily due to decreases in sales prices. As a
result of the decrease in sales prices received during 2009 as compared to 2008,
production taxes decreased by $350,251 during 2009.





General
and administrative costs decreased from $1,012,874 incurred during the year
ended December 31, 2008 to $664,555 incurred during the year ended December 31,
2009, primarily due to decreased legal fees and decreased overhead charges.
Effective April 1, 2008 Reef implemented a new method for allocating overhead
that takes actual overhead and allocates it based upon the summation of
revenues, expenses, and actual capital costs incurred. The administrative
overhead charge to the Partnership decreased from $856,371 for the year ended
December 31, 2008 to $529,185 for the year ended December 31, 2009.





The rapid
decline in crude oil and natural gas prices that occurred during the first half
of 2009 and the impairment of proved properties caused the Partnership’s net
income for the year overall to decline. Average sales prices during the first
quarter of 2010 have continued to increase from 2009 levels. The Partnership
expects that it will generate net income in 2010.





Year
Ended December 31, 2008 compared to Year Ended December 31, 2007





The
Partnership had net income totaling $4,448,003 during 2008, compared to a net
loss totaling $8,288,564 during 2007. The significant improvement in operating
results is due to three primary factors. First, the Partnership had three
significant discoveries during the last half of 2007. These three wells began
production in September 2007, January 2008, and May 2008, and led to a 65.4%
increase in crude oil sales and a 76.3% increase in natural gas sales volumes
during 2008 compared to 2007 sales volumes. Second, the Partnership saw
increases in the 2008 average sales prices for its crude oil of 33.3% and
natural gas of 28.4% compared to 2007. Finally, the Partnership had no
impairment of proved properties during 2008, compared to $9,466,246 of
impairment of proved properties during 2007. The Partnership had $172,930 of
impairment of unproved properties during 2008, compared to no impairment of
unproved properties during 2007.





The
impairment of proved properties during 2007 occurred during the first half of
2007, and was the result of large reductions in estimated reserves from four
2006 Partnership wells as a result of production declines significantly in
excess of original estimates. As shown in the Partnership’s Quarterly Report on
Form 10-Q for the period ended June 30, 2007, estimated reserves declined from
335,435 barrels of oil equivalent (BOE) to 172,111 BOE during the first half of
2007.  Subsequent to June 30, 2007, the Partnership had three major
discoveries for which the discounted future net cash flows was estimated at
approximately $16.3 million at December 31, 2007, accounting for approximately
70% of the total estimated discounted future net cash flows of $23.3 million at
December 31, 2007. The Partnership was not allowed to reverse the impairment
expense taken during the first half of 2007, even though the increase in the
estimated discounted future net cash flows from these discoveries during the
second half of 2007 exceeded the impairment taken during the first half of
2007.





At
December 31, 2008, the estimated discounted future net cash flows of the
Partnership totaled $10,651,949, compared to $23,341,108 at December 31, 2007.
Approximately $7.9 million of the reduction is the direct result of lower base
sales prices at December 31, 2008, which impacts the estimated economic life of
Partnership wells and estimated economic reserves to be produced from
Partnership wells. The base year end prices used in the Partnership’s reserve
studies were $44.60 per barrel of oil and $5.71 per MCF of natural gas at
December 31, 2008, compared to $89.16 per barrel of oil and $7.207 per MCF of
natural gas at December 31, 2007. Even with this drop in estimated discounted
future net cash flows from 2007 to 2008, the Partnership recorded no impairment
of proved properties during 2008 because of the impact of the three significant
discoveries during the last half of 2007.


22


The
impact of the Partnership’s 2007 discoveries began with third quarter 2007
results, when the first of the three significant 2007 discoveries began
producing. Third quarter 2008 volumes were negatively impacted by Hurricanes
Gustav and  Ike, which resulted in several Partnership wells being
shut-in for portions of August and September 2008.





During
2008, four Partnership wells accounted for 82.6% of Partnership oil and gas
sales revenues, and these four wells account for 88.9% of total Partnership
reserves at December 31, 2008.





Production
expenses rose during 2008 in conjunction with new wells placed into production
during 2007 and 2008, and increases in sales prices. As a result of the increase
in sales prices received during 2008 as compared to 2007, production taxes
increased by $350,989 during 2008.





During
2008, the Partnership participated in the drilling of four wells in the Sand
Dunes prospect, which have been classified as unsuccessful during the fourth
quarter of 2008, and drilled one successful exploratory well during the third
quarter of 2008 which began production in November 2008.





General
and administrative costs increased from $227,249 in 2007 to $1,012,874 in 2008
as a result of two primary factors. Reef implemented a new method for allocating
overhead that takes actual overhead and allocates it based upon the summation of
revenues, expenses, and capital costs incurred. Under the prior method of
allocating overhead, not all allocable general and administrative expenses were
charged to the Partnership during 2007. In addition, during the fourth quarter
expenses were incurred in connection with Sarbanes-Oxley compliance and
improvement of financial reporting. The Partnership expects to have continuing
costs during 2009 related to Sarbanes-Oxley compliance, as the Partnership is
required to be Sarbanes-Oxley compliant by December 31, 2009. Third party costs
in connection with improvement of financial reporting ended during January
2009.  The administrative overhead charge to the Partnership for the
year ended December 31, 2008 was $856,371, compared to $141,081 for the year
ended December 31, 2007.





The rapid
decline in crude oil and natural gas prices that occurred during the fourth
quarter of 2008, the impairment of unproved properties, and the significant
increase in general and administrative costs incurred during the fourth quarter
of 2008 caused the Partnership’s net income for the quarter to decline to only
$5,701. RELP and Reef are working to cut overhead costs, and even with costs in
connection with Sarbanes-Oxley compliance, the Partnership expects to incur
overall lower general and administrative costs during 2009. Average sales prices
during the first quarter of 2009 will continue to decline from fourth quarter
2008 levels. The Partnership expects that prior to depletion expense and any
possible impairment charges it will continue to generate net income.
Nonetheless, 2009 results are expected to decline significantly from 2008
results.





Partnership
interest income comes from the short-term investment of unexpended partner
capital contributions, and therefore deceases during the drilling phase of
operations as partner capital is expended to purchase working interests in
prospects and to drill and complete wells. Interest income declined from
$387,479 during 2007 to $15,179 during 2008 as a result of the Partnership
completing its drilling phase of operations during the first quarter of
2008.





Off-Balance
Sheet Arrangements





The
Partnership does not participate in transactions that generate relationships
with unconsolidated entities or financial partnerships, such as entities often
referred to as structure finance or special purpose entities (SPEs), which would
have been established for the purpose of facilitating off-balance sheet
arrangements or other contractually narrow or limited purposes.  As of
December 31, 2009, 2008 and 2007, the Partnership was not involved in any
unconsolidated SPE transactions or any other off-balance sheet
arrangements.

ITEM
      7A.
            QUANTITATIVE
      AND QUALITATIVE DISCLOSURE ABOUT MARKET
RISK





Interest
Rate Risk





The
Partnership has not borrowed any funds to date. The Partnership Agreement allows
borrowings from banks or other financial sources of up to 25% of the aggregate
capital contributions to the Partnership without investor approval, provided the
lender agrees it will have no recourse against individual investor partners, and
allows borrowings in excess of 25% of the aggregate capital contributions to the
Partnership with the consent of investor partners. Should the Partnership elect
to borrow monies for additional drilling activity on Partnership prospects, it
will be subject to the interest rate risk inherent in borrowing activities.
Changes in interest rates could significantly affect the Partnership’s results
of operations and the amount of net cash flow available for partner
distributions. Also, to the extent that changes in interest rates affect general
economic conditions, the Partnership will be affected by such
changes.





Commodity
Price Risk





The
Partnership has not and does not expect to engage in commodity futures trading
or hedging activities or enter into derivative financial instrument transactions
for trading or other speculative purposes.  The Partnership sells a
vast majority of its production from successful oil and gas wells on a
month-to-month basis at current spot market prices. Accordingly, the Partnership
is at risk for the volatility in commodity prices inherent in the oil and gas
industry, and the level of commodity prices has a significant impact on the
Partnership's results of operations.





Assuming
the production levels we attained during the year ended December 31, 2009, a 10%
change in the price received for our crude oil would have had an approximate
$197,915 impact on our crude oil revenues, and a 10% change in the price
received for our natural gas would have had an approximate $273,975 impact on
our natural gas revenues.

the Partnership’s disclosure controls and procedures are effective to ensure
that information required to be disclosed by the Partnership in reports that it
files or submits under the Exchange Act is recorded, processed, summarized, and
reported within the time periods specified in Securities and Exchange Commission
rules and forms, and includes controls and procedures designed to ensure that
information required to be disclosed by us in such reports is accumulated and
communicated to our management, including the principal executive officer and
principal financial officer of our managing general partner, as appropriate to
allow timely decisions regarding financial disclosure.

Management
Report on Internal Control Over Financial Reporting





Management
of the Partnership is responsible for establishing and maintaining adequate
internal control over financial reporting, as such term is defined in Exchange
Act Rule 13a-15(f). Our management conducted an evaluation of the effectiveness
of our internal control over financial reporting based on the framework in
Internal Control - Integrated Framework issued by the Committee of Sponsoring
Organizations of the Treadway Commission. Based on this evaluation under the
framework in Internal Control – Integrated Framework, management of the
Partnership concluded that the Partnership’s internal control over financial
reporting was effective as of December 31, 2009.





This
annual report does not include an attestation report of the Partnership’s
registered public accounting firm regarding internal control over financial
reporting. Management’s report was not subject to attestation by the
Partnership’s registered public accounting firm pursuant to temporary rules of
the SEC that permit the Partnership to provide only management’s report in this
annual report.





Changes
in Internal Controls





There
have not been any changes in the Partnership’s internal controls over financial
reporting during the fiscal quarter ended December 31, 2009 that have materially
affected, or are reasonably likely to materially affect, the Partnership’s
internal control over financial reporting.

committee financial expert or a nominating committee.

ethics.  Employees of the Partnership's managing general partner,
Reef, must comply with Reef's Code of Ethics, a copy of which will be provided
to investor partners, without charge, upon request made to Reef Oil & Gas

Reef's
"partnership interest," as described in the table above, refers only to its
interest as managing general partner and does not include the interest Reef has
as the result of its purchase of units in the Partnership, or the 1% interest
Reef has as the result of its payment of 1% of all leasehold, drilling, and
completion costs.  Reef purchased 5.00% of the outstanding Partnership
units. Reef received a 10% interest as managing general partner of the
Partnership and a 1% interest as a result of Reef’s payment of 1% of all
leasehold, drilling, and completion costs for a total of an 11%
interest.  This 11% interest is not represented by partnership
units.  Reef has a total interest in the Partnership of
15.45%.





Reef is
entitled to receive a management fee equal to 15% of the Partnership
subscriptions exclusive of the units purchased by Reef. From this amount Reef
pays all of the Partnership's organization and offering costs, including sales
commissions. The management fee is payable to Reef in two parts. Reef initially
received an amount not to exceed 13.5% to cover actual sales commissions and
actual organization and offering costs. The remainder of the management fee is
paid to Reef from the net cash flow available for partner distributions, at a
rate not to exceed $1 million per year. The total management fee owed Reef is
$5,369,615. The Partnership recorded $5,319,615 of this amount as offering
costs, and $50,000 as organization costs. Of this amount, $4,564,826 has been
paid to Reef to cover actual sales commissions and organization and offering
costs, and $804,789 has been paid to Reef from net cash flows of the
Partnership.





Reef is
reimbursed for direct costs and all documented out-of-pocket expenses incurred
on behalf of the Partnership, including administrative costs. During the years
ended December 31, 2009, 2008 and 2007, the Partnership reimbursed Reef $1,004,
$126,680, and $754,097, respectively, for technical services costs which have
been capitalized as project costs, and $545,623, $856,371, and $141,081,
respectively, for administrative costs included as general and administrative
expenses.


27


Operator
fees are payable to RELP for the wells on the twelve prospects where RELP serves
as operator.  RELP receives operator fees during the drilling and
production phase of each well at the competitive rate in the geographical area
where the well is located.  These fees are charged as a monthly fee
per well as agreed to in an operating agreement signed by the Partnership and
participating third party working interest owners in the well. During the years
ended December 31, 2009, 2008 and 2007, the Partnership paid operator fees
totaling $17,235, $14,105, and $3,662 to RELP. RELP serves as operator for
twelve Partnership prospects upon which three successful wells and sixteen
unsuccessful wells have been drilled, including the eight Sand Dunes wells
classified as unsuccessful that have not yet been plugged and
abandoned.





Compensation
Committee





Because
the Partnership has no directors, it does not have a compensation
committee.





ITEM 12.
            SECURITY
      OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT AND RELATED
      STOCKHOLDER MATTERS





The
following table sets forth information as of December 31, 2009 concerning all

(1) Reef
Oil & Gas Partners, L.P.’s address is 1901 N. Central Expressway, Suite 300,
Richardson, Texas 75080.





The
managing general partner received a 10% interest in the Partnership as
compensation for forming the Partnership, and also holds a 1% interest in the
Partnership as a result of paying 1% of all leasehold, drilling and completion
costs. In addition to this 11% interest not represented by Partnership units,
Reef purchased 5% of the 1,507.260 Partnership units and, therefore, holds 5% of
the 89% interest in the Partnership (4.45%) held by the unit
holders.





ITEM
      13.

      RELATIONSHIPS AND RELATED TRANSACTIONS, AND DIRECTOR

Report of
Independent Registered Public Accounting Firm





The
Partners


Reef
Global Energy VI, L.P.





We have
audited the accompanying balance sheets of Reef Global Energy VI, L.P. as of
December 31, 2009 and 2008, and the related statements of operations,
partnership equity, and cash flows for each of the three years in the period
ended December 31, 2009. These financial statements are the responsibility of
the Partnership’s management. Our responsibility is to express an opinion on
these financial statements based on our audits.




We
conducted our audits in accordance with the standards of the Public Company
Accounting Oversight Board (United States). Those standards require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. The Partnership is not required to
have, nor were we engaged to perform, an audit of its internal control over
financial reporting. An audit includes consideration of internal control over
financial reporting as a basis for designing audit procedures that are
appropriate in the circumstances, but not for the purpose of expressing an
opinion on the effectiveness of the Partnership’s internal control over
financial reporting. Accordingly, we express no such opinion. An audit also
includes examining, on a test basis, evidence supporting the amounts and
disclosures in the financial statements, assessing the accounting principles
used and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.





In our
opinion, the financial statements referred to above present fairly, in all
material respects, the financial position of Reef Global Energy VI, L.P. at
December 31, 2009 and 2008, and the results of its operations and its cash flows
for each of the three years in the period ended December 31, 2009, in conformity
with accounting principles generally accepted in the United States of
America.





As
discussed in Note 2 to the financial statements, effective December 31, 2009,
the Partnership changed its reserve estimates and related disclosures as a
result of adopting new oil and gas reserve estimation and disclosure
requirements.

1.
Organization and Basis of Presentation





Reef
Global Energy VI, L.P. (the “Partnership”) is the first in a series of four
Nevada limited partnerships comprising a program called Reef Global Energy
Ventures II (the “Program”), pursuant to an S-1 Registration Statement declared
effective by the Securities and Exchange Commission (the “SEC”) on July 7, 2005.
In order to be formed, each partnership was required to sell a minimum of 40
partnership units at $25,000 per unit, including units purchased by the managing
general partner. Each partnership formed as a part of the program offered a
minimum of 1,000 and a maximum of 2,000 units for sale. The Program was
authorized to sell up to 1,600 limited partner units and 6,400 general partner
units during the period beginning July 8, 2005 through July 7, 2007. The
Partnership offered 2,000 units for sale ($50,000,000); consisting of up to 400
limited partner units and up to 1,600 general partner units. Investor funds were
held in escrow and were subject to reimbursement with interest if the minimum
number of units was not sold. The Program filed a prospectus supplement with the
SEC on July 8, 2005 describing the Partnership, and commenced offering units in
the Partnership. Upon reaching the minimum subscription level, the Partnership
was formed on July 18, 2005. The Partnership offering closed October 31, 2005,
with sales to outside investors totaling 1,190.561 general partner units and
241.336 limited partner units, and sales to the managing general partner
totaling 75.363 general partner units.





The
Partnership is a Nevada limited partnership formed under the Nevada Uniform
Limited Partnership Act. Reef Oil & Gas Partners, L.P. (“Reef”) serves as
the Partnership’s managing general partner. Partnership interests are held by
the managing general partner and investor partners who are general and limited
partners (“investor partners”). The managing general partner received a 10%
interest in the Partnership as compensation for forming the Partnership, and
also holds a 1% interest in the Partnership as a result of paying 1% of all
leasehold, drilling and completion costs. This 11% interest is not represented
by Partnership units. In addition, Reef purchased 5% of the Partnership units
and, therefore, holds 5% of the 89% interest in the Partnership (4.45%) held by
the unit holders. The Partnership purchased working interests in exploratory and
developmental drilling prospects and drilled oil and gas wells located primarily
onshore in the continental United States and in U.S. coastal waters in the Gulf
of Mexico. Other partnerships formed as a part of this Program, as well as other
partnerships managed by Reef, also own interests in some of the prospects
purchased by this Partnership. In instances where Reef-affiliated entities own a
majority working interest in a prospect, wells drilled on that prospect may be
operated by Reef Exploration, L.P. (“RELP”), an affiliate of the managing
general partner.





Pursuant
to the Partnership Agreement of the Partnership, all general partner units held
by investors other than the managing general partner were converted into limited
partner units. This conversion of general partner units into limited partner
units occurred during the 3rd quarter
of 2008. The general partner equity at June 30, 2008 was transferred to limited
partner equity, and all income and expense items subsequent to the second
quarter of 2008 were allocated between the managing general partner and the
limited partners.





Under the
terms of the partnership agreement, certain income and expense items are
allocated differently between the managing general partner and the investor
partners.  Allocations of income and expense to the managing general
partner and investor partners are made quarterly based upon the number and type
of partnership units held at the end of the quarter.





Organization
and offering costs are allocated 100% to investor partners, as the managing
general partner purchases its units net of the 15% fee for organization and
offering costs. Monthly cash distributions to partners are based upon the number
and type of partnership units held at the close of the prior month. Cash
distributions to partners of the net cash flow from interest income and crude
oil and natural gas sales revenues, less operating, general and administrative,
and other costs are distributed 15.45% to the managing general partner (based
upon the 11% interest not represented by units and the 4.45% interest
represented by Partnership units) and 84.55% to investor
partners.

Summary of Accounting Policies





Use
of Estimates





The
preparation of financial statements in conformity with accounting principles
generally accepted in the United States of America requires management to make
estimates and assumptions that affect the amounts reported in the financial
statements and accompanying notes. Actual results could differ from these
estimates.





Cash
and Cash Equivalents





The
Partnership considers all highly liquid investments with maturity dates of no
more than three months from the purchase date to be cash equivalents. Cash and
cash equivalents consist of demand deposits and money market investments
invested with a major national bank, which at times may exceed federally insured
limits. The Partnership has not experienced any losses in such accounts, and
does not expect any loss from this exposure. The carrying value of the
Partnership’s cash equivalents approximates fair value.





Risks
and Uncertainties





Historically,
the oil and gas market has experienced significant price fluctuations. Prices
are impacted by local weather, supply in the area, availability and price of
competitive fuels, seasonal variations in local demand, limited transportation
capacity to other regions, and the worldwide supply and demand balance for crude
oil.





The
Partnership has not engaged in commodity futures trading or hedging activities
and has not entered into derivative financial instrument transactions for
trading or other speculative purposes. Accordingly, the Partnership is at risk
for the volatility in commodity prices inherent in the oil and gas industry, and
the level of commodity prices has a significant impact on the Partnership’s
results of operations.





Oil
and Gas Properties





The
Partnership follows the full cost method of accounting for oil and gas
properties. Under this method, all direct costs and certain indirect costs
associated with acquisition of properties and successful as well as unsuccessful
exploration and development activities are capitalized. Depreciation, depletion,
and amortization of capitalized oil and gas properties and estimated future
development costs, excluding unproved properties, are based on the
unit-of-production method using estimated proved reserves, as determined by
independent petroleum engineers.  For these purposes, proved natural
gas reserves are converted to equivalent barrels of crude oil at a rate of 6 Mcf
to 1 Bbl.





In
applying the full cost method at December 31, 2009, the Partnership performs a
quarterly ceiling test on the capitalized costs of oil and gas properties,
whereby the capitalized costs of oil and gas properties are limited to sum of
the estimated future net revenues from proved reserves using prices that are the
12-month un-weighted arithmetic average of the first-day-of-the-month price for
crude oil and natural gas held constant and discounted at 10%, plus the lower of
cost or estimated fair value of  unproved properties, if any, for
2009. If capitalized costs exceed the ceiling, an impairment loss is recognized
for the amount by which the capitalized costs exceed the ceiling, and is shown
as a reduction of oil and gas properties and as property impairment expense on
the Partnership’s statement of operations.  No gain or loss is
recognized upon sale or disposition of oil and gas properties, unless such a
sale would significantly alter the rate of depletion and amortization. During
the years ended December 31, 2009, 2008 and 2007, the Partnership recognized
property impairment expense of proved properties totaling $4,629,688, $0, and
$9,466,246 respectively.





Unproved
properties consist of undeveloped leasehold interest. Investments in unproved
properties are not depleted pending determination of the existence of proved
reserves. Unproved properties are assessed for impairment quarterly as of the
balance sheet date by considering the primary lease term, the holding period of
the properties, geologic data obtained relating to the properties, and other
drilling activity in the immediate area of the properties. Any impairment
resulting from this quarterly assessment is reported as property impairment
expense in the current period, as appropriate. During the year ended December
31, 2008, the Partnership fully impaired its unproved properties by recognizing
$172,930, of property impairment expense.

Notes to
Financial Statements (continued)


Estimates
of Proved Oil and Gas Reserves





Estimates
of the Partnership’s proved reserves at December 31, 2009 have been prepared and
presented in accordance with new SEC rules and accounting standards. These new
rules are effective for fiscal years ending on or after December 31, 2009, and
require SEC reporting entities to prepare their reserve estimates using revised
reserve definitions and revised pricing based upon the un-weighted arithmetic
average of the first-day-of-the-month commodity prices over the preceding 12
month period and current costs. Estimates of the Partnership’s proved reserves
at December 31, 2008 and 2007 have been prepared and presented using previous
SEC rules and accounting standards that required pricing based upon
end-of-period commodity prices and costs. Future prices and costs may be
materially higher or lower than these prices and costs, which would impact the
estimate of reserves and future cash flows. Our proved reserve information
included in this report was based upon evaluations prepared by independent
petroleum engineers.




Reserves
and their relation to estimated future net cash flows impact the Partnership’s
depletion and impairment calculations. As a result, adjustments to depletion and
impairment are made concurrently with changes to reserve estimates. If proved
reserve estimates decline, the rate at which depletion expense is recorded
increases, reducing net income. A decline in estimated proved reserves and
future cash flows also reduces the capitalized cost ceiling and may result in
increased impairment expense.




The
adoption of the new SEC rules and accounting standards at December 31, 2009
resulted in a downward adjustment of $2,019,550 to the estimated discounted
future cash flows from proved reserves, and in a reduction of 9,745 BOE
equivalent of proved reserves. Additionally, the change resulted in increases of
$15,483 and $1,503,338 in depletion and impairment expense,
respectively,  in the fourth quarter of 2009.




Restoration,
Removal, and Environmental Liabilities





The
Partnership is subject to extensive Federal, state and local environmental laws
and regulations. These laws regulate the discharge of materials into the
environment and may require the Partnership to remove or mitigate the
environmental effects of the disposal or release of petroleum substances at
various sites. Environmental expenditures are expensed or capitalized depending
on their future economic benefit. Expenditures that relate to an existing
condition caused by past operations and that have no future economic benefit are
expensed.





Liabilities
for expenditures of a non-capital nature are recorded when environmental
assessments and/or remediation is probable, and the costs can be reasonably
estimated. Such liabilities are generally undiscounted values unless the timing
of cash payments for the liability or component is fixed or reliably
determinable.





Asset
retirement costs and liabilities associated with future site restoration and
abandonment of long-lived assets are initially measured at fair value which
approximates the cost a third party would incur in performing the tasks
necessary to retire such assets. The fair value is recognized in the financial
statements as the present value of expected future cash expenditures for site
restoration and abandonment. Subsequent to the initial measurement, the effect
of the passage of time on the liability for the net asset retirement obligation
(accretion expense) and the amortization of the asset retirement cost are
recognized in the results of operations.





The
following table summarizes the Partnership’s asset retirement obligation for the
years ended December 31, 2009 and 2008.

Recognition
of Revenue





The
Partnership enters into sales contracts for disposition of its share of crude
oil and natural gas production from productive wells. Revenues are recognized
based upon the Partnership’s share of metered volumes delivered to its
purchasers each month. The Partnership had no material gas imbalances at
December 31, 2009, 2008, and 2007.

Income
Taxes





The
Partnership’s net income or loss flows directly through to its partners, who are
responsible for the payment of Federal taxes on their respective share of any
income or loss. Therefore, there is no provision for federal income taxes in the
accompanying financial statements.





As of
December 31, 2009, the financial reporting basis of the Partnership’s assets
exceeds the tax basis of the assets by approximately $4.24 million, primarily
due to the difference between property impairment costs deducted for financial
reporting purposes and intangible drilling costs deducted for income tax
purposes.





Accounting
for Uncertainty in Income Taxes





FASB
provides guidance on accounting for uncertainty in income taxes. This guidance
is intended to clarify the accounting for uncertainty in income taxes recognized
in a company’s financial statements and prescribes the recognition and
measurement of a tax position taken or expected to be taken in a tax return. It
also provides guidance on de-recognition, classification, interest and
penalties, accounting in interim periods, disclosure and
transition.





Under
this guidance, evaluation of a tax position is a two-step process. The first
step is to determine whether it is more-likely-than-not that a tax position will
be sustained upon examination, including the resolution of any related appeals
or litigation based on the technical merits of that position. The second step is
to measure a tax position that meets the more-likely-than-not threshold to
determine the amount of benefit to be recognized in the financial statements. A
tax position is measured at the largest amount of benefit that is greater than
50% likely of being realized upon ultimate settlement.





Tax
positions that previously failed to meet the more-likely-than-not recognition
threshold should be recognized in the first subsequent period in which the
threshold is met. Previously recognized tax positions that no longer meet the
more-likely-than-not criteria should be de-recognized in the first subsequent
reporting period in which the threshold is no longer met. Penalties and interest
are classified as income tax expense.





Based on
the Partnership’s assessment, there are no material uncertain tax positions as
of December 31, 2009.





Fair
Value of Financial Instruments





The
estimated fair values for financial instruments have been determined at discrete
points in time based on relevant market information. These estimates involve
uncertainties and cannot be determined with precision. The estimated fair
value of cash, accounts receivable and accounts payable approximates their
carrying value due to their short-term nature.





Reclassifications





Certain
information provided for prior years has been reclassified to conform to the
current year presentation adopted as of December 31, 2009.





Recently
Adopted Accounting Pronouncements





Modernization
of Oil and Gas Reporting





In
January 2009, the SEC adopted new rules related to modernizing reserve
calculation and disclosure requirements for oil and gas companies, which became
effective prospectively for annual reporting periods ending on or after December
31, 2009. In addition to expanding the definition and disclosure requirements
for crude oil and natural gas reserves, the new rule changes the requirements
for determining quantities of crude oil and natural gas reserves. The new rule
requires disclosure of crude oil and natural gas proved reserves by geographical
area, using the un-weighted arithmetic average of first-day-of-the-month
commodity prices over the preceding 12-month period, rather than end-of-period
prices, and allows the use of reliable technologies to estimate proved crude oil
and natural gas reserves, if those technologies have been demonstrated to result
in reliable conclusions about reserve volumes.  In addition, in
January 2010, the FASB issued guidance relating to crude oil and natural gas
reserve estimation and disclosures to provide consistency with the new SEC
rules.  The Partnership adopted the new standards effective December
31, 2009.  The new standards are applied prospectively as a change in
estimate. The effect of applying the un-weighted arithmetic average of
first-day-of-the-month commodity prices over the preceding 12-month period,
versus applying the 2009 end-of-period price, decreased net proved reserves by
5.1%. The standardized measure of discounted future net cash flows for the year
ended December 31, 2009 was lower by $2,019,550 using the new rule as compared
to amounts calculated using the previous rule.  The effect of applying
the new rule resulted in additional depletion expense of $15,483 and additional
impairment expense of $1,503,338.

Accounting
Standards Codification




In
June 2009, the Financial Accounting Standards Board (“FASB”) issued
guidance on the accounting standards codification and the hierarchy of generally
accepted accounting principles. The accounting standards codification is
intended to be the source of authoritative US GAAP and reporting standards
as issued by the FASB. Its primary purpose is to improve clarity and use of
existing standards by grouping authoritative literature under common topics. The
accounting standards codification is effective for financial statements issued
for interim and annual periods ending after September 15, 2009. The
Partnership now describes the authoritative guidance used within the footnotes
but no longer uses numerical references. The accounting standards codification
does not change or alter existing US GAAP, and there is no expected impact
on the Partnership’s financial position, results of operations or cash
flows.





Fair
Value Measurement of Liabilities




In
August 2009, the FASB issued new guidance for the accounting for the fair
value measurement of liabilities.  The new guidance provides clarification
that in certain circumstances in which a quoted price in an active market for
the identical liability is not available, a company is required to measure fair
value using one or more of the following valuation techniques: the quoted price
of the identical liability when traded as an asset, the quoted prices for
similar liabilities or similar liabilities when traded as assets, and/or another
valuation technique that is consistent with the principles of fair value
measurements.  The new guidance is effective for interim and annual periods
beginning after August 27, 2009.  The Partnership does not
expect that the provisions of the new guidance will have a material
effect on its results of operations, financial position or
liquidity.





Subsequent
Events





In
May 2009, the FASB issued new guidance for accounting for subsequent
events.  This guidance established general standards of accounting for and
disclosure of events that occur after the balance sheet date but before
financial statements are issued or are available to be issued. This guidance is
effective for interim and annual reporting periods ending after June 15, 2009.
The Partnership adopted the provisions of this guidance for the period ended
June 30, 2009. In February 2010, the FASB issued an update to this guidance.
Among other provisions, this update provides that an entity that is a SEC filer
is not required to disclose the date through which subsequent events have been
evaluated.  The Partnership adopted the provisions on its effective
date of February 24, 2010. There was no impact on the Partnership’s operating
results, financial position or cash flows.





Recognition
and Presentation of Other-Than-Temporary Impairments





In April
2009, the FASB issued new guidance related to the presentation and disclosure of
other-than-temporary impairments on debt and equity securities.  The
new guidance amends the other-than-temporary impairment guidance for debt
securities to make the guidance more operational and to improve the presentation
and disclosure of other-than-temporary impairments on debt and equity securities
in the financial statements.  The guidance does not amend existing
recognition and measurement guidance for equity securities, but does establish a
new method of recognizing and reporting for debt
securities.  Disclosure requirements for impaired debt and equity
securities have been expanded significantly and are now required quarterly, as
well as annually.  This guidance became effective for interim and
annual reporting periods ending after June 15, 2009.  Comparative
disclosures are required for periods ending after the initial
adoption.  This guidance did not have an impact on the Partnership’s
financial position, results of operations or cash flows.

Interim
Reporting of Fair Value of Financial Instruments





In
April 2009, the FASB issued new guidance related to the disclosure of the
fair value of financial instruments.  The new guidance amends SFAS No. 107,
“Disclosures about Fair Value of Financial Instruments,” to require disclosures
about fair value of financial instruments for interim reporting
periods.  The guidance also amends APB Opinion No. 28, “Interim
Financial Reporting,” to require those disclosures about the fair value of
financial instruments in summarized financial information at interim reporting
periods.  This guidance is effective for reporting periods ending
after June 15, 2009.  The adoption of this guidance did not have any
impact on the Partnership’s results of operations, cash flows, or financial
position.





3.
Transactions with Affiliates





The
Partnership has no employees. RELP employs a staff including geologists,
petroleum engineers, landmen and accounting personnel who administer all of the
Partnership’s operations. The Partnership reimburses RELP for technical and
administrative services at cost. During the years ended December 31, 2009, 2008,
and 2007 the Partnership incurred technical services and administrative costs
totaling $546,627, $983,051, and $895,178, respectively. Of these amounts
$1,004, $126,680, and $754,097 represent technical services costs capitalized as
project costs, and $545,623, $856,371, and 141,081 represent administrative
costs included as general and administrative expenses.





Reef
contributes 1% of all leasehold, drilling, and completion costs when incurred.
During the year ended December 31, 2009, this 1% obligation totaled $7,605. Reef
also purchased 5% of the Partnership units and pays 5% of the 99% of these costs
paid by the unit holders (4.95%). In connection with the 1% obligation, Reef
owed the Partnership $12,019 at December 31, 2008 and $15,098 at December 31,
2007.





RELP
processes joint interest billings and revenue payments on behalf of the
Partnership. At December 31, 2009 and 2008, RELP owed the Partnership $731,390
and $144,486, respectively, for net revenues processed in excess of joint
interest and technical and administrative charges.





Accounts
payable to affiliates as of December 31, 2009 and 2008 also included $0 and
$144,789, respectively, for the unpaid portion of the 15% management fee due
Reef for organization and offering costs, including sales commissions. The
management fee is payable in two parts. Reef initially received an amount not to
exceed 13.5% to recover actual commissions and organization and offering costs.
The balances payable at December 31, 2009 and 2008 represent the unpaid portion
of the management fee in excess of actual commissions and organization and
offering costs, and is paid to Reef from the oil and gas cash flows available
for partner distributions, at a rate not to exceed $1 million per year. During
2008, the Partnership reimbursed $600,000 of this amount to Reef. The
Partnership completed payment of the December 31, 2008 balance due during March
2009.





If an
affiliate of Reef serves as operator of a Partnership prospect, then operator
fees are payable to the affiliate. Under such circumstances, such affiliate
receives fees at the competitive rate in the geographical area where the
prospect is located during the drilling and production phase of operations.
These fees are charged as a monthly fee per well as agreed to in an operating
agreement signed by the Partnership as well as outside third party working
interest owners in the well. During the year ended December 31, 2007, the
Partnership paid drilling overhead fees totaling $2,149 to RELP. During the
years ended December 31, 2009, 2008 and 2007, the Partnership paid operating
overhead fees totaling $17,235, $14,105 and $1,513 to RELP.

Major Customers





The
Partnership sells crude oil and natural gas on credit terms to refiners,
pipelines, marketers, and other users of petroleum commodities. Revenues are
received directly from these parties or, in certain circumstances, paid to the
operator of the property who disburses to the Partnership its percentage share
of the revenues. During the year ended December 31, 2009, one marketer and one
operator accounted for 51.3% and 31.2% of the Partnership’s crude oil and
natural gas revenues, respectively.  During the year ended December
31, 2008, one marketer and two operators accounted for 57.2%, 17.4%, and 11.4%
of the Partnership’s crude oil and natural gas revenues, respectively. During
the year ended December 31, 2007, one marketer and two operators accounted for
53.9%, 23.0%, and 10.4% of the Partnership’s crude oil and natural gas revenues,
respectively. Due to the competitive nature of the market for purchase of crude
oil and natural gas, the Partnership does not believe that the loss of any
particular purchaser would have a material adverse impact on the
Partnership.

Commitments and Contingencies




The
Partnership is not currently involved in any legal proceedings.





6.  Partnership
Equity





Sales of
Partnership units began on July 8, 2005. Proceeds received were placed into an
interest bearing escrow account until the Partnership reached the minimum
subscription level of 40 units. The Partnership was formed on July 18, 2005, and
the sale of Partnership units was closed on October 31, 2005. The Partnership
raised $35,797,434 from the sale of 1,431.897 Partnership units to investor
partners. Reef purchased 75.363 units (5%) for $1,601,464. Reef also contributes
1% of all leasehold, drilling, and completion costs when incurred, in addition
to having paid its pro rata share (4.95%) of the leasehold, drilling, and
completion costs paid by the Partnership. In connection with this obligation,
Reef has contributed $316,361 to the Partnership at December 31,
2009.





All
units, except those purchased by Reef, paid a 15% management fee to Reef to pay
for Partnership organization and offering costs, including sales commissions.
These costs totaled $5,369,615, leaving net capital contributions of $32,345,644
available for Partnership oil & gas activities. Of the $5,369,615 management
fee, offering costs were $5,319,615 and organization costs were $50,000. The
Partnership has drilled fifty one wells at December 31, 2009, and has completed
drilling operations with the capital raised by the Partnership.





Reef
exclusively manages and controls all aspects of the business of the Partnership.
The Partnership agreement prohibits participation by investor partners in the
Partnership’s day-to-day business decisions.





7.
Partnership Prospects





As of
December 31, 2009, the Partnership owns working interests in twenty
developmental prospects and fourteen exploratory prospects, upon which a total
of fifty one wells have been drilled.





The
Partnership drilled fifteen successful developmental wells, and twenty
unsuccessful developmental wells, including the eight Sand Dunes wells described
below. The Partnership has drilled eight successful exploratory wells and eight
unsuccessful exploratory wells. Five of the successful developmental wells and
three of the successful exploratory wells have ceased production.





The
Partnership participated in the drilling of eight developmental wells on the
Sand Dunes prospect located in Eddy County, New Mexico during the fourth quarter
of 2007 and the first quarter of 2008. Initial testing confirmed the presence of
crude oil and natural gas in all eight wells. However, the field was temporarily
shut-in because of the lack of electric service and because of the high cost of
trucking offsite the salt water volumes associated with the production of the
crude oil and natural gas from the wells. Electrical service to the eight Sand
Dunes wells was connected in September 2008. Based upon initial testing, larger
bottom hole pumps were placed below the well perforations in three of the wells
and testing was resumed in late September 2008 to determine the three wells’
commercial productivity. Water continued to be trucked offsite, and RELP applied
for and received a permit which would allow for the conversion of one of the
existing eight Sand Dunes wells into a water disposal well. RELP also explored
the possibility of drilling a ninth well as a salt water disposal well for the
field. Testing results on two of the three wells were positive, and salt water
production volumes declined as a result of pumping off the wells using the
larger bottom hole pumps. However, the price of crude oil also declined at a
rapid rate while testing was being conducted. In late December 2008 two of the
three testing wells were shut-in again. Crude oil prices continued declining to
a level below $40 per barrel. In February 2009, following a mechanical failure
in the third testing well, RELP, as operator, shut-in the field. The eight wells
cannot be commercially productive without efficient salt water disposal
capabilities, and none of the options regarding salt water disposal were
economically viable at first quarter 2009 commodity prices. As a result, as of
December 31, 2008, the eight Sand Dunes wells were classified as unsuccessful,
and no crude oil and natural gas reserves for these wells were included in the
December 31, 2008 reserve information presented in this Annual
Report.

Global Energy VI, L.P.


Notes to
Financial Statements (continued)





Beginning
with March 2009, oil sales prices increased from levels below $40 per barrel to
between $60 and $70 per barrel. As a result of this increase in prices, in
October 2009, Reef approved the conversion of one of the eight wells on the Sand
Dunes development prospect located in Eddy County, New Mexico to a salt water
disposal well. The conversion work began in March 2010. Upon conversion of this
well to a salt water disposal well, three of the current Sand Dunes wells are
expected to be placed on full time production during the second quarter of 2010.
RELP believes, based upon testing already performed, that the disposal capacity
of the well to be converted will be such that only three Sand Dunes wells can be
placed on full time production. However, if possible, additional wells may be
placed on production. RELP will determine what actions to take regarding the
other Sand Dunes wells after a period of evaluation of this initial conversion.
The estimated cost of the well conversion to this Partnership is expected to be
approximately $79,290 (unaudited).  This cost will be paid for by the
Partnership by retaining a portion of the funds normally paid out in
distributions to the partners. There are 5,330 BBL of crude oil and 8,830 MCF of
natural gas reserves (unaudited) for the three wells expected to be placed on
full time production included in the December 31, 2009 reserve information
presented in this Annual Report.





The
Partnership also owns interests in unproved property consisting of un-drilled
leasehold interest (11 potential drilling locations) in the Sand Dunes prospect.
The Partnership fully impaired this unproved property during the fourth quarter
of 2008 based upon the eight already drilled Sand Dunes wells being classified
as unsuccessful at December 31, 2008. The Partnership currently has no plans to
conduct any drilling operations on this acreage.

Crude
Oil and Natural Gas Reserves





Recent
SEC and FASB Rule Making Activity





In
January 2009, the SEC adopted new rules related to modernizing reserve
calculation and disclosure requirements for oil and gas companies, which became
effective prospectively for annual reporting periods ending on or after December
31, 2009. The Partnership adopted the rules effective December 31, 2009, and the
rule changes, including those related to pricing and technology, are included in
the Partnership’s reserve estimates. See Note 2, “Summary of Significant
Accounting Policies – Modernization of Oil and Gas Reporting.”





In
accordance with new SEC rules, estimates of the Partnership’s proved reserves
and future net revenues are made using the unweighted arithmetic average of
first-day-of-the-month commodity prices over the preceding 12 month period for
the year ended December 31, 2009. These prices are held constant in accordance
with SEC guidelines for the economic life of the wells included in the reserve
report but are adjusted by well in accordance with sales contracts, energy
content quality, transportation, compression and gathering fees, and regional
price differentials. Estimated quantities of proved reserves and future net
revenues are affected by crude oil and natural gas prices, which have fluctuated
significantly in recent years.





The new
rules resulted in the use of lower prices at December 31, 2009 for both crude
oil and natural gas than would have been used under the previous rules, and
resulted in a downward adjustment of approximately 9,745 BOE to our proved
reserves as of December 31, 2009, as compared to the old end-of-period prices
rule.





Net
Proved Developed Reserve Summary





The
reserve information presented below is based upon estimates of net proved
reserves that were prepared by the independent petroleum engineering firms
Forrest A. Garb & Associates, Inc., as of December 31, 2009, and by Gleason
Engineering as of December 31, 2008 and 2007.   A copy of the
Forrest A. Garb & Associates summary reserve report is included as Exhibit
99.1 to this Annual Report.  Proved crude oil and natural gas reserves
are the estimated quantities of crude oil and natural gas which geological and
engineering data demonstrate with reasonable certainty to be economically
recoverable in future years from known reservoirs under existing economic
conditions, operating methods and governmental regulations (i.e. prices and
costs as of the date the estimate is made).  Proved developed reserves
are reserves that can be expected to be recovered through existing wells with
existing equipment and operating methods.  At December 31, 2009, all
of the Partnership’s reserves are classified as proved developed
reserves.  All of the Partnership’s reserves are located in the United
States.

Standardized
Measure of Discounted Future Net Cash Flows





Certain
information concerning the assumptions used in computing the valuation of proved
reserves and their inherent limitations are discussed below.  The
Partnership believes such information is essential for a proper understanding
and assessment of the data presented.




For the
year ended December 31, 2009, future cash inflows are computed by applying the
new SEC pricing, which holds constant the unweighted arithmetic average of the
first-day-of-the-month prices for crude oil and natural gas over the preceding
12-month period as the price basis for estimating the Partnership’s proved
reserves. For the year ended December 31, 2009, calculations were made using
average prices of $61.08 per barrel of crude oil and $3.83 per MCF of natural
gas. For the years ending December 31, 2008 and 2007, future cash inflows were
computed by applying the former SEC pricing rules, which hold constant the
end-of-year price for crude oil and natural gas as the price basis for
estimating the Partnership’s proved reserves. During 2008, the calculations were
made using average prices of $44.60 per barrel of oil and $5.71 per MCF of
natural gas.  During 2007, the calculations were made using average
prices of $89.16 per barrel of oil and $7.21 per MCF of natural gas. Prices and
costs are held constant for the life of the wells, however, prices are adjusted
by well in accordance with sales contracts, energy content quality,
transportation, compression and gathering fees, and regional price
differentials.

Notes to
Financial Statements (continued)





These
assumptions used to compute estimated future cash inflows do not necessarily
reflect Reef’s expectations of the Partnership’s actual revenues or costs, nor
their present worth. Further, actual future net cash flows will be affected by
factors such as the amount and timing of actual production, supply and demand
for crude oil and natural gas, and changes in governmental regulations and tax
rates. Sales prices of both crude oil and natural gas have fluctuated
significantly in recent years. Reef, as managing general partner, does not rely
upon the following information in making investment and operating decisions for
the Partnership.





Future
development and production costs are computed by estimating the expenditures to
be incurred in developing and producing the proved crude oil and natural gas
reserves at the end of the year, based on year-end costs and assuming
continuation of existing economic conditions.





A 10%
annual discount rate is used to reflect the timing of the future net cash flows
relating to proved reserves.
