ITEM 1.  BUSINESS.

General

    PDC 1999-B Limited Partnership ("the Partnership") is a limited
partnership formed on September 13, 1999 pursuant to the West Virginia
Uniform Limited Partnership Act.  Petroleum Development Corporation ("PDC")
serves as Managing General Partner of the Partnership.

    Since the commencement of operations on September 13, 1999, the
Partnership has been engaged in onshore, domestic gas exploration
exclusively in the Northern Appalachian Basin, Michigan Basin and the Rocky
Mountain Region.  One limited partner contributed $5,000; a total of 250
additional general partners contributed initial capital of $5,534,893; and
PDC (Managing General Partner) contributed $1,204,927 in capital as a
participant in accordance with contribution provisions of the Limited
Partnership Agreement (the Agreement).

    Under the terms of the Agreement, the allocation of revenues is as
follows:
                                          Allocation
                                         of Revenues
          Additional General and
            Limited Partners                  80%
          Managing General Partner            20%

    Operating and direct costs are allocated and charged to the additional
general and limited partners and the Managing General Partner in the same
percentages as revenues are allocated.  Leasehold, drilling and completion
costs, and equipment costs are borne 80% by the additional general and
limited partners and 20% by the Managing General Partner.

Employees

    The Partnership has no employees, however, PDC has approximately 91
employees which include a staff of geologists, petroleum engineers, landmen
and accounting personnel who administer all of the partnership's operations.

Plan of Operations

    The Partnership participated in the drilling of twenty-seven gross wells
and will continue to operate and produce its twenty-six gross productive
wells.  The Partnership does not have unexpended initial capital and no
additional drilling activity is planned.

    See Item 2 herein for information concerning the Partnership's gas
wells.

Markets for Oil and Gas

    The availability of a market for any oil and gas produced from the
operations of the Partnership will depend upon a number of factors beyond
the control of the Partnership which cannot be accurately predicted.  These
factors include the proximity of the Partnership wells to and the capacity
of natural gas pipelines, the availability and price of competitive fuels,
fluctuations in seasonal supply and demand, and government regulation of
supply and demand created by its pricing and allocation restrictions.
Oversupplies of gas can be expected to occur from time to time and may
result in the Partnership's wells being shut-in or curtailed.  Increased
imports of oil and natural gas have occurred and are expected to continue.
The effects of such imports could adversely impact the market for domestic
oil and natural gas.






                                     2

Derivatives and Hedging Activities

The Managing General Partner utilizes commodity based derivative instruments
as hedges to manage a portion of its and various limited partnerships'
exposure to price volatility stemming from natural gas production and
marketing activities.  These instruments consist of natural gas futures and
option contracts traded on the New York Mercantile Exchange.  The futures
and option contracts hedge committed and anticipated natural gas purchases
and sales, generally forecasted to occur within a 12 month period. The
Managing General Partner does not hold or issue derivatives for trading or
speculative purposes and permits utilization of hedges only if there is an
underlying physical position.

The Managing General Partner has extensive experience with the use of
financial hedges to reduce the risk and impact of natural gas price changes.
These hedges are used to coordinate fixed and variable priced purchases and
sales  and to "lock in" fixed prices from time to time for the Managing
General Partner and its various limited partnerships' share of production.
In order for future contracts to serve as effective hedges, there must be
sufficient correlation to the underlaying hedged transaction.  While hedging
can help provide price protection if spot prices drop, hedges can also
limited upside potential.

Despite the measure taken by the Managing General Partner to attempt to
control price risk, the Partnership remains subject to price fluctuations
for natural gas sold in the spot market.  The Managing General Partner
continues to evaluate the potential for reducing these risks by entering
into hedge transactions.  In addition, the Managing General Partner may also
close out any portion of hedges that may exist from time to time.


Competition

    The Partnership competes in marketing its gas with numerous companies
and individuals, many of which have financial resources, staffs and
facilities substantially greater than those of the Partnership or Petroleum
Development Corporation.

State Regulations

    State regulatory authorities have established rules and regulations
requiring permits for well operations, reclamation bonds and reports
concerning operations.  States also have statutes and regulations concerning
the spacing of wells, environmental matters, and conservation, and have
established regulations concerning the unitization and pooling of oil and
gas properties and maximum rates of production from oil and gas wells.  The
Partnership believes it has complied in all material respects with
applicable state regulations.

Federal Regulations

    Regulation of Liquid Hydrocarbons.  Liquid hydrocarbons (including crude
oil and natural gas liquids) were subject to federal price and allocation
controls until January 1981 when controls were effectively eliminated by
executive order of the President.  As a result, to the extent the
Partnership sells oil produced from its properties, those sales are at
unregulated market prices.

    Although it appears unlikely under present circumstances that controls
will be reimposed upon liquid hydrocarbons, it is possible Congress may
enact such legislation at a future date.  The impact of such legislation on
the Partnership would be minimal since the partnership expects to sell only
small quantities of liquid hydrocarbons.






                                     3

    Natural Gas Regulation.  Sale of natural gas by the Partnership is
subject to regulation of production, transportation and pricing by
governmental regulatory agencies.  Generally, the regulatory agency in the
state where a producing well is located regulates production activities and,
in addition, the transportation of gas sold intrastate.  The Federal Energy
Regulatory Commission (FERC) regulates the operation and cost of interstate
pipeline operators who transport gas.  Currently the price of gas sold by
the Partnership is not regulated by any state or federal agency.

    The FERC has adopted major changes in certain of its regulations and
continues to make additional changes that will significantly affect future
transportation and marketing of natural gas.

    The Partnership is uncertain how the recent or proposed regulations will
affect the marketing of its gas because it is unable to predict how all
interstate pipelines that receive its gas will respond to such rulemakings.

    Proposed Regulation.  Numerous proposals concerning energy are being
considered by the United States Congress, various state legislatures and
regulatory agencies.  The possible outcome and effect of these proposals
cannot be accurately predicted.

    Environmental and Safety Regulation.  The Partnership believes that it
complies, in all material respects, with all legislation and regulations
affecting its operations in the drilling and production of oil and gas wells
and the discharge of wastes.  To date, compliance with such provisions and
regulations has not had a material effect upon the Partnership's
expenditures for capital equipment, its operations or its competitive
position.  The cost of such compliance is not anticipated to be material in
the future.

</TABLE>

    A "productive well" is a well producing, or capable of producing, oil
and gas in commercial quantities.  For purposes of the above table, a "gross
well" is one in which the Partnership has a working interest and a "net
well" is a gross well multiplied by the Partnership's working interest to
which it is entitled under its drilling agreement.

Title to Properties

    The Partnership's interests in producing acreage are in the form of
assigned direct interests in leases.  Such properties are subject to
customary royalty interests generally contracted for in connection with the
acquisition of properties, and could be subject to liens incident to
operating agreements, liens for current taxes and other burdens.  The
Partnership believes that none of these burdens materially interfere with
the use of such properties in the operation of the Partnership's business.

    As is customary in the oil and gas industry, little or no investigation
of title is made at the time of acquisition of undeveloped properties (other
than a preliminary review of local mineral records).  Investigations are
generally made, including in most cases receiving a title opinion of legal
counsel, before commencement of drilling operations.  A thorough examination
of title has been made with respect to all of the Partnership's producing
properties and the Partnership believes that it has generally satisfactory
title to such properties.

ITEM 3.  LEGAL PROCEEDINGS.

    The Managing General partner as driller/operator is not party to any
legal action that would materially affect the Managing General Partner's or
Partnership's operations or financial statements.

ITEM 5.  MARKET FOR THE REGISTRANT'S COMMON EQUITY AND SECURITY HOLDER
MATTERS.

    At December 31, 1999, PDC 1999-B Limited Partnership had one Managing
General Partner, 1 Limited Partner who fully paid for 0.25 units at $20,000
per unit of limited partnership interests and a total of 250 Additional
General Partners who fully paid for 276.74 units at $20,000 per unit of
additional general partnership interests.  No established public trading
market exists for the interests.

    Limited and additional general partnership interests are transferable,
however no assignee of an interest in the Partnership can become a
substituted partner without the written consent of the transferor and the
Managing General Partner.

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

Liquidity and Capital Resources

    The Partnership was funded with initial Limited and Additional General
Partner contributions of $5,539,893 and the Managing General Partner
contributed $1,204,927 in accordance with the Agreement.  Syndication cost
and Management fee of $720,186 were incurred leaving available capital of
$6,024,634 for Partnership activities.

    The Partnership began exploration and development activities subsequent
to the funding of the Partnership.  Twenty-seven wells have been drilled,
twenty-six of which have been completed as producers.  No additional wells
are planned to be drilled.

    The Partnership had net working capital at December 31, 1999 of
$121,872.

    Operations are expected to be conducted with available funds and
revenues generated from oil and gas activities.  No bank borrowings are
anticipated.







                                     6

Results of Operations

1999 Results

    Oil and gas sales production commenced during the fourth quarter of 1999
with revenue distributions to the partners to commence in the first quarter
of 2000.

    The Partnership's revenues from natural gas sales will be affected by
changes in prices.  Natural gas prices are subject to general market
conditions which drive the pricing changes.

    The principal effects of inflation upon the Partnership relate to the
costs required to drill, complete and operate oil and gas wells.  The
Partnership expects these costs to remain somewhat stable over the next
year.

Year 2000 Issue

    The Partnership experienced no known disruptions as a result of the year
date change and intends to continue monitoring its critical systems at
various other date changes during the Year 2000.

    The Partnership expenditures for addressing Year 2000 issues were not
material, nor does the Partnership expect to incur any significant costs
addressing Year 2000 issues in the future.

New Accounting Standards

    Statement of Accounting Standards No. 133, Accounting for Derivative
Instruments and Hedging Activities (SFAS No. 133), was issued by the
Financial Accounting Standards Board in June, 1998.  SFAS No. 133
standardized the accounting for derivative instruments, including certain
derivative instruments embedded in other contracts.  SFAS No. 133 is
effective for years beginning after June 15, 2000; however, early adoption
is permitted.  On adoption, the provisions of SFAS No. 133 must be applied
prospectively.  At the present time, the Company cannot determine the impact
that SFAS No. 133 will have on its financial statements upon adoption, as
such impact will be based on the extent of derivative instruments, such as
natural gas futures and option contracts, outstanding at the date of
adoption.

                       Notes to Financial Statements

                             December 31, 1999

(1)  Summary of Significant Accounting Policies

     Partnership Financial Statement Presentation Basis

     The financial statements include only those assets, liabilities and
       results of operations of the partners which relate to the business
       of PDC 1998-B Limited Partnership (the Partnership).  The statements
       do not include any assets, liabilities, revenues or expenses
       attributable to any of the partners' other activities.

     Oil and Gas Properties

     The Partnership follows the successful efforts method of accounting for
       the cost of exploring for and developing oil and gas reserves.  Under
       this method, costs of development wells, including equipment and
       intangible drilling costs related to both producing wells and
       developmental dry holes, and successful exploratory wells are
       capitalized and amortized on an annual basis to operations by the
       units-of-production method using estimated proved developed reserves
       determined at year end by an independent petroleum engineer, Wright
       & Company, Inc.  If a determination is made that an exploratory well
       has not discovered economically producible reserves, then its costs
       are expensed as dry hole costs.

     The Partnership assesses impairment of capitalized costs of proved oil
       and gas properties by comparing net capitalized costs to undiscounted
       future cash flows on a field-by-field basis using expected prices.
       Prices utilized in each years calculation for measurement purposes
       and expected costs are held constant.  If net capitalized costs
       exceed undiscounted future net cash flow, the measurement of
       impairment is based on estimated fair value which would consider
       future discounted cash flows.

     Based on the Managing General Partner's experience, management believes
       site restoration, dismantlement and abandonment costs, net of salvage
       to be immaterial in relation to operating costs.  These costs are
       being expensed when incurred.

     Income Taxes

     Since the taxable income or loss of the Partnership is reported in the
       separate tax returns of the partners, no provision has been made for
       income taxes on the Partnership's books.

     Under federal income tax laws, regulations and administrative rulings,
       certain types of transactions may be accorded varying
       interpretations.  Accordingly, the Partnership's tax return and,
       consequently, individual tax returns of the partners may be changed
       to conform to the tax treatment resulting from a review by the
       Internal Revenue Service.
                                                              (Continued)

                   (A West Virginia Limited Partnership)

                 Notes to Financial Statements, Continued

     Derivatives and Hedging Activities

     The Managing General Partner utilizes commodity based derivative
       instruments as hedges to manage a portion of its and various limited
       partnerships' exposure to price volatility stemming from natural gas
       production and marketing activities.  These instruments consist of
       natural gas futures and option contracts traded on the New York
       Mercantile Exchange.  The futures and option contracts hedge
       committed and anticipated natural gas purchases and sales, generally
       forecasted to occur within a 12 month period. The Managing General
       Partner does not hold or issue derivatives for trading or speculative
       purposes and permits utilization of hedges only if there is an
       underlying physical position.

     As of December 31, 1999 and 1998, the Managing General Partner had
       futures contracts for the purchase of $4,318,000 and $1,120,300 of
       natural gas, respectively relating to the Managing General Partner
       and the Managing General Partner's various limited partnerships.
       While these contracts have nominal carrying value, their fair value,
       represented by the estimated amount that would be received upon
       termination of the contracts, based on market quotes, was a net value
       of $350,000 at December 31, 1999 and $(105,400) at December 31, 1998.
       Realized gains and losses on these contracts are allocated to the
       Managing General Partner and the Managing General Partner's various
       limited partnerships.

     Use of Estimates

     Management of the Partnership has made a number of estimates and
       assumptions relating to the reporting of assets and liabilities and
       revenues and expenses and the disclosure of contingent assets and
       liabilities to prepare these financial statements in conformity with
       generally accepted accounting principles.  Actual results could
       differ from those estimates.  Estimates which are particularly
       significant to the financial statements include estimates of oil and
       gas reserves and future cash flows from oil and gas properties.

(2)  Organization

     The Partnership was organized as a limited partnership on September 13,
       1999, in accordance with the laws of the State of West Virginia for
       the purpose of engaging in the drilling, completion and operation of
       oil and gas development and exploratory wells in the Northern
       Appalachian and Michigan Basins and Rocky Mountain Region.

     Purchasers of partnership units subscribed to and fully paid for 0.25
       units of limited partner interest and 276.74 units of additional
       general partner interests at $20,000 per unit (Investor Partners).
       Petroleum Development Corporation has been designated the Managing
       General Partner of the Partnership.  Although costs, revenues and
       cash distributions allocable to the limited and additional general
       partners are shared pro rata based upon the amount of their
       subscriptions, including the Managing General Partner to the extent
       of its capital contributions, there are significant differences in
       the federal income tax effects and liability associated with these
       different types of units in the Partnership.

                      PDC 1999-B LIMITED PARTNERSHIP
                   (A West Virginia Limited Partnership)

                 Notes to Financial Statements, Continued

     Upon completion of the drilling phase of the Partnership's wells, all
       additional general partners units are converted into units of limited
       partner interests and thereafter become limited partners of the
       Partnership.  Limited partners do not have any rights to convert
       their units into units of additional general partner interests in the
       Partnership.

     In accordance with the terms of the Partnership Agreement (the

  (1) Organization and Offering Costs, net of the Dealer Manager
      commissions, discounts, due diligence expenses, and wholesaling fees
      of the Partnership were paid by the Managing General Partner and not
      from Partnership funds.  In addition, Organization and Offering
      Costs in excess of 10-1/2% of Subscriptions were paid by the
      Managing General Partner, without recourse to the Partnership.

  (2) To the extent that Investor Partners receive preferred cash
      distributions, the allocations for Investor Partners will be
      increased accordingly and the allocation for the Managing General
      Partner will likewise be decreased.

  (3) As set forth in the following paragraph, the allocation of profits,
      losses and cash distributions of the Managing General Partner might
      be increased, and the allocation of profits, losses, and cash
      distributions of the Investor Partners might be decreased in the
      event that the Managing General Partner were to invest more than the
      Managing General Partner's minimum required Capital Contribution to
      cover tangible equipment and lease costs.

      The Managing General Partner will pay for the Partnership's share of
      all Leases and tangible well equipment.  The entire Capital
      Contribution of the Investor Partners, after payment of brokerage
      commissions, due diligence reimbursement, and the Management Fee,
      will be utilized to pay for intangible drilling costs.  In the event
      that the Intangible Drilling Costs exceed the funds of the Investor
      Partners available for payment of Intangible Drilling Costs (herein
      "excess IDC"), a portion of the Capital Contribution of the Managing

      General Partner may be used to pay such excess IDC.  If the cost of
      Leases and tangible well equipment were to exceed the Managing
      General Partner's Capital Contribution of 21-3/4 percent of the
      aggregate Capital Contribution of the Investor Partners, then the
      Managing General Partner will increase its Capital Contribution to
      fund such additional capital requirements and the Managing General
      Partner's allocation of profits, losses, and cash distributions will
      be increased to equal the percentage arrived at by dividing the
      Capital Contribution made by the Managing General Partner by the
      Capital Available for Investment; the allocation of the Investor
      Partners will be decreased accordingly.

(5)   Costs Relating to Oil and Gas Activities

      The Partnership is engaged solely in oil and gas activities, all
        of which are located in the continental United States.
        Information regarding aggregate capitalized costs and results of
        operations for these activities is located in the basic financial
        statements.  Costs capitalized for these activities at December
        31, 1999, are as follows:

          Lease acquisition costs                        $  159,676
          Intangible development costs                    4,960,231
          Well equipment                                    891,709
          Exploratory dry hole cost                         (51,586)
                                                        $ 5,960,030

   The following costs were incurred for the Partnership's oil and gas
      activities:

                                                         Period from
                                                      September 13, 1999
                                                  (date of inception) to
                                                     December 31, 1999

          Costs incurred:
            Property acquisition costs                    $  159,676
            Development costs                              5,800,354
            Exploratory dry hole cost                         51,586
                                                          $6,011,616

(6)   Income Taxes

      As a result of the differences in the treatment of certain items for
        income tax purposes as opposed to financial reporting purposes,
        primarily depreciation, depletion and amortization of oil and gas
        properties and the recognition of intangible drilling costs as an
        expense or capital item, the income tax basis of oil and gas
        properties differs from the basis used for financial reporting
        purposes.   At December 31, 1999, the income tax basis of the
        Partnership's oil and gas properties was $1,202,323.
