PART I.


ITEM 1.           BUSINESS

      General

      The Geodyne Energy Income Limited Partnership I-D (the "I-D Partnership"),
Geodyne  Energy Income  Limited  Partnership  I-E (the "I-E  Partnership"),  and
Geodyne  Energy  Income  Limited   Partnership   I-F  (the  "I-F   Partnership")
(collectively,  the  "Partnerships")  are limited  partnerships formed under the
Oklahoma  Revised Uniform Limited  Partnership Act. Each Partnership is composed
of public  investors as limited  partners (the "Limited  Partners")  and Geodyne
Resources, Inc. ("Geodyne"), a Delaware corporation, as the general partner. The
Partnerships commenced operations on the dates set forth below:

                                              Date of
                      Partnership           Activation
                      -----------       ------------------

                          I-D           March 4, 1986
                          I-E           September 10, 1986
                          I-F           December 16, 1986

      Immediately following  activation,  each Partnership invested as a general
partner in a separate  Oklahoma general  partnership which actually conducts the
Partnerships' production operations.  Geodyne serves as managing partner of such
general partnerships.  Unless the context indicates otherwise, all references to
any single  Partnership or all of the Partnerships in this Annual Report on Form
10-K405  ("Annual  Report") are  references to the  Partnership  and its related
general  partnership,  collectively.  In addition,  unless the context indicates
otherwise,  all  references  to the "General  Partner" in this Annual Report are
references  to Geodyne as the general  partner of the  Partnerships,  and as the
managing partner of the related general partnerships.

      The  General  Partner  currently  serves as general  partner of 26 limited
partnerships,  including the Partnerships. The General Partner is a wholly-owned
subsidiary  of Samson  Investment  Company.  Samson  Investment  Company and its
various  corporate  subsidiaries,  including the General  Partner  (collectively
"Samson"),  are  primarily  engaged in the  production  and  development  of and
exploration  for oil and gas  reserves  and the  acquisition  and  operation  of
producing   properties.   At  December  31,  2000,  Samson  owned  interests  in
approximately 13,500 oil and gas wells located in 19 states of the United States
and the countries of Canada, Venezuela, and Russia. At December 31, 2000, Samson
operated  approximately  2,700  oil and gas  wells  located  in 14 states of the
United States, as well as Canada, Venezuela, and Russia.



                                      -4-
<PAGE>



      The Partnerships are currently engaged in the business of owning interests
in producing oil and gas properties  located in the  continental  United States.
The Partnerships may also engage to a limited extent in development  drilling on
producing oil and gas  properties as required for the prudent  management of the
Partnerships.

      As limited partnerships,  the Partnerships have no officers, directors, or
employees. They rely instead on the personnel of the General Partner and Samson.
As of February 15, 2001, Samson employed approximately 965 persons. No employees
are covered by collective  bargaining  agreements,  and management believes that
Samson  provides  a  sound  employee  relations  environment.   For  information
regarding the executive officers of the General Partner, see "Item 10. Directors
and Executive Officers of the General Partner."

      The General Partner's and the Partnerships' principal place of business is
located at Samson Plaza,  Two West Second Street,  Tulsa,  Oklahoma  74103,  and
their telephone number is (918) 583-1791 or (888) 436-3963 [(888) GEODYNE].

      Pursuant to the terms of the partnership  agreements for the  Partnerships
(the  "Partnership  Agreements"),  the  Partnerships  would have  terminated  on
December 31, 1999. However, the Partnership  Agreements provide that the General
Partner may extend the term of each  Partnership  for up to five  periods of two
years each. The General Partner has extended the terms of  Partnerships  for the
first two year extension period to December 31, 2001.

      Funding

      Although  the  Partnership  Agreements  permit each  Partnership  to incur
borrowings,   operations   and  expenses  are  currently   funded  out  of  each
Partnership's  revenues from oil and gas sales.  The General Partner may, but is
not required to, advance funds to a Partnership  for the same purposes for which
Partnership borrowings are authorized.


      Principal Products Produced and Services Rendered

      The  Partnerships'  sole  business  is  the  production  of,  and  related
incidental  development  of,  oil and gas.  The  Partnerships  do not  refine or
otherwise  process crude oil and  condensate.  The  Partnerships do not hold any
patents,  trademarks,  licenses,  or  concessions  and are  not a  party  to any
government  contracts.  The  Partnerships  have no  backlog of orders and do not
participate in research and development  activities.  The  Partnerships  are not
presently  encountering  shortages  of  oilfield  tubular  goods,   compressors,
production material, or other equipment.

      Competition and Marketing

      The Partnerships' revenues, net income or loss, cash flows, carrying value
of oil and gas  properties,  and amount of oil and gas which can be economically
produced depend  substantially  upon the prevailing  prices for oil and gas. Oil
and gas prices (and  consequently the Partnerships'  profitability)  depend on a
number of factors that are beyond the control of the Partnerships. These factors
include worldwide political instability  (especially in oil-producing  regions),
United Nations export embargoes,  the supply and price of foreign imports of oil
and gas, the level of consumer  product demand (which can be heavily  influenced
by weather patterns),  the level of domestic oil and gas production,  government
regulations  and taxes,  the price and  availability of alternative  fuels,  the
overall   economic   environment,   and  the   availability   and   capacity  of
transportation and processing facilities.  The effect of these factors on future
oil and gas industry trends cannot be accurately  predicted or  anticipated.  In
addition, the domestic oil and gas industry is highly competitive,  with a large
number of companies and  individuals  engaged in the exploration and development
of oil and gas properties.  Predicting future prices is not possible. Concerning
past trends,  oil and gas prices in the United States have been highly  volatile
for many years.

      Over the past ten years average yearly  wellhead gas prices have generally
been in the $1.40 to $2.40 per Mcf range.  However,  due to  unusual  supply and
demand  circumstances  gas prices are  currently  substantially  higher than the
upper end of this range. Substantially all of the Partnerships' gas reserves are
being sold on the "spot  market."  Prices on the spot market are subject to wide
seasonal and regional pricing  fluctuations due to the highly competitive nature
of the spot market. In addition, such spot market sales are generally short-term
in nature  and are  dependent  upon the  obtaining  of  transportation  services
provided by pipelines.  Spot prices for the  Partnerships'  gas  increased  from
approximately  $2.24 per Mcf at December 31, 1999 to approximately $6.03 per Mcf
at  December  31,  2000.  Such prices were on an MMBTU basis and differ from the
prices actually received by the Partnerships due to transportation and marketing
costs, BTU adjustments, and regional price and quality differences.

      For the past ten years,  average  oil prices  have  generally  been in the
$16.00 to $24.00 per barrel  range,  but have been  extremely  volatile over the
past three  years.  Due to global  consumption  and  supply  trends as well as a
slowdown in Asian energy demand,  oil prices in late 1997 and early 1998 reached
historically low levels,  dropping to as low as approximately  $9.25 per barrel.
However, production curtailment agreements among major oil producing nations and
other supply and demand  factors have caused  recent oil prices to climb to over
$30.00 per barrel in some markets. It is not known whether this trend will



                                      -6-
<PAGE>



continue.  Prices for the Partnerships' oil increased from approximately  $22.75
per barrel at December 31, 1999 to  approximately  $27.52 per barrel at December
31, 2000.

      Future  prices  for both oil and gas will  likely  be  different  from the
prices in effect on December 31, 2000. While it is impossible to predict whether
future oil and gas prices will (i) stabilize,  (ii) increase, or (iii) decrease,
management  believes it is possible that average oil and gas prices for the near
future  may be  somewhat  higher  than the prices  experienced  over the past 10
years.


      Significant Customers

      The  following  customers  accounted  for  ten  percent  or  more  of  the
Partnerships' oil and gas sales during the year ended December 31, 2000:

      In  the  event  of  interruption  of  purchases  by  one  or  more  of the
Partnerships'  significant  customers  or the  cessation  or material  change in
availability  of  open  access  transportation  by  the  Partnerships'  pipeline
transporters,  the Partnerships may encounter  difficulty in marketing their gas
and in maintaining historic sales levels.  Management does not expect any of its
open access transporters to seek authorization to terminate their transportation
services.  Even  if the  services  were  terminated,  management  believes  that
alternatives  would  be  available  whereby  the  Partnerships  would be able to
continue to market their gas.

      The  Partnerships'  principal  customers  for  crude  oil  production  are
refiners and other companies  which have pipeline  facilities near the producing
properties  of the  Partnerships.  In the  event  pipeline  facilities  are  not
conveniently  available to  production  areas,  crude oil is usually  trucked by
purchasers to storage facilities.

      Oil, Gas, and Environmental Control Regulations

      Regulation  of Production  Operations -- The  production of oil and gas is
subject to  extensive  federal and state laws and  regulations  governing a wide
variety of matters, including the drilling and spacing of wells, allowable rates
of  production,  prevention  of  waste  and  pollution,  and  protection  of the
environment.  In  addition  to the direct  costs  borne in  complying  with such
regulations,  operations and revenues may be impacted to the extent that certain
regulations limit oil and gas production to below economic levels.

      Regulation  of Sales and  Transportation  of Oil and Gas -- Sales of crude
oil and  condensate  are made by the  Partnerships  at market prices and are not
subject to price  controls.  The sale of gas may be subject to both  federal and
state laws and  regulations.  The provisions of these laws and  regulations  are
complex  and  affect  all who  produce,  resell,  transport,  or  purchase  gas,
including the  Partnerships.  Although  virtually all of the  Partnerships'  gas
production  is not subject to price  regulation,  other  regulations  affect the
availability of gas transportation  services and the ability of gas consumers to
continue to purchase or use gas at current levels. Accordingly, such regulations
may have a material  effect on the  Partnerships'  operations and projections of
future oil and gas production and revenues.

      Future  Legislation --  Legislation  affecting the oil and gas industry is
under  constant  review  for  amendment  or  expansion.  Because  such  laws and
regulations  are frequently  amended or  reinterpreted,  management is unable to
predict what  additional  energy  legislation  may be proposed or enacted or the
future cost and impact of complying with existing or future regulations.

      Regulation of the Environment -- The Partnerships'  operations are subject
to numerous laws and  regulations  governing the discharge of materials into the
environment or otherwise relating to environmental  protection.  Compliance with
such  laws  and  regulations,   together  with  any  penalties   resulting  from
noncompliance  may  increase  the cost of the  Partnerships'  operations  or may
affect  the  Partnerships'   ability  to  timely  complete  existing  or  future
activities.  Management  anticipates  that  various  local,  state,  and federal
environmental  control  agencies will have an  increasing  impact on oil and gas
operations.

      Insurance Coverage

      The  Partnerships  are  subject  to  all  of  the  risks  inherent  in the
exploration for and production of oil and gas,  including  blowouts,  pollution,
fires, and other casualties.  The Partnerships maintain insurance coverage as is
customary for entities of a similar size engaged in  operations  similar to that
of the  Partnerships,  but losses can occur from uninsurable risks or in amounts
in excess of existing  insurance  coverage.  The occurrence of an event which is
not fully  covered by  insurance  could have a  material  adverse  effect on the
Partnerships' financial condition and results of operations.

----------

(1)   The  designation  of a well  as an oil  well  or gas  well  is made by the
      General  Partner based on the relative  amount of oil and gas reserves for
      the well.  Regardless of a well's oil or gas  designation,  it may produce
      oil, gas, or both oil and gas.
(2)   As used in this Annual  Report,  "gross  well" refers to a well in which a
      working interest is owned,  accordingly,  the number of gross wells is the
      total number of wells in which a working interest is owned.
(3)   As  used  in this  Annual  Report,  "net  well"  refers  to the sum of the
      fractional  working  interests  owned in gross wells.  For example,  a 15%
      working interest in a well represents one gross well, but 0.15 net well.

      Drilling Activities

      During the year ended  December  31,  2000,  the  Partnerships  indirectly
participated in the drilling of the following wells. The Partnerships do not own
working interests in any of the wells;  therefore,  they did not incur any costs
associated with the drilling activity:

      Oil and Gas Production, Revenue, and Price History

      The following tables set forth certain historical  information  concerning
the oil  (including  condensates)  and  gas  production,  net of all  royalties,
overriding  royalties,  and other third party  interests,  of the  Partnerships,
revenues   attributable  to  such   production,   and  certain  price  and  cost
information.  As used in the following tables, direct operating expenses include
lease operating  expenses and production  taxes. In addition,  gas production is
converted to oil equivalents at the rate of six Mcf per barrel, representing the
estimated  relative energy content of gas and oil, which rate is not necessarily
indicative of the relationship of oil and gas prices.  The respective  prices of

      Proved Reserves and Net Present Value

      The following table sets forth each Partnership's estimated proved oil and
gas reserves  and net present  value  therefrom  as of December  31,  2000.  The
schedule  of  quantities  of proved oil and gas  reserves  was  prepared  by the
General  Partner in accordance  with the rules  prescribed by the Securities and
Exchange  Commission (the "SEC").  Certain  reserve  information was reviewed by
Ryder Scott Company,  L.P. ("Ryder Scott"), an independent petroleum engineering
firm. As used throughout this Annual Report,  "proved  reserves" refers to those
estimated  quantities of crude oil, gas, and gas liquids  which  geological  and
engineering  data  demonstrate  with  reasonable  certainty to be recoverable in
future  years from known oil and gas  reservoirs  under  existing  economic  and
operating conditions.





                                      -13-
<PAGE>



      Net present  value  represents  estimated  future gross cash flow from the
production and sale of proved reserves,  net of estimated oil and gas production
costs (including production taxes, ad valorem taxes, and operating expenses) and
estimated  future  development  costs,  discounted at 10% per annum. Net present
value  attributable to the  Partnerships'  proved reserves was calculated on the
basis of current  costs and prices at December  31,  2000.  Such prices were not
escalated  except in  certain  circumstances  where  escalations  were fixed and
readily determinable in accordance with applicable contract provisions.  The oil
and gas prices at  December  31,  2000 have caused the  estimates  of  remaining
economically recoverable reserves, as well as the value placed on said reserves,
to be substantially higher than in the past several years. Any decrease in these
prices  would result in a  corresponding  reduction in the estimate of remaining
reserves.  The prices used in calculating the net present value  attributable to
the Partnerships'  proved reserves do not necessarily  reflect market prices for
oil  and gas  production  subsequent  to  December  31,  2000.  There  can be no
assurance  that the prices  used in  calculating  the net  present  value of the
Partnerships' proved reserves at December 31, 2000 will actually be realized for
such  production.  The General Partner  believes that it is unlikely that prices
will remain at their current high levels.

      The process of  estimating  oil and gas  reserves  is  complex,  requiring
significant  subjective  decisions in the  evaluation  of available  geological,
engineering,  and  economic  data  for  each  reservoir.  The  data  for a given
reservoir may change substantially over time as a result of, among other things,
additional development activity, production history, and viability of production
under varying economic conditions;  consequently, it is reasonably possible that
material  revisions to existing reserve  estimates may occur in the near future.
Although  every  reasonable  effort has been made to ensure  that these  reserve
estimates represent the most accurate assessment  possible,  the significance of
the  subjective  decisions  required and variances in available data for various
reservoirs  make these  estimates  generally  less precise than other  estimates
presented in connection with financial statement disclosures.

      Title to Oil and Gas Properties

      Management believes that the Partnerships have satisfactory title to their
oil and gas properties.  Record title to all of the Partnerships'  properties is
held by either the Partnerships or Geodyne Nominee Corporation,  an affiliate of
the General Partner.

      Title to the  Partnerships'  properties  is subject to customary  royalty,
overriding  royalty,   carried,   working,   and  other  similar  interests  and
contractual  arrangements  customary in the oil and gas  industry,  to liens for
current taxes not yet due, and to other  encumbrances.  Management believes that
such burdens do not materially detract from the value of such properties or from
the Partnerships' interest therein or materially interfere with their use in the
operation of the Partnerships' business.


ITEM 3.     LEGAL PROCEEDINGS

      To the knowledge of the General  Partner,  neither the General Partner nor
the Partnerships or their properties are subject to any litigation,  the results
of which  would  have a  material  effect on the  Partnerships'  or the  General
Partner's financial condition or operations.


ITEM 4.     SUBMISSION OF MATTERS TO A VOTE OF LIMITED PARTNERS

      There were no matters  submitted to a vote of the Limited  Partners of any
Partnership during 2000.

      Units were initially sold for a price of $1,000.  The Units are not traded
on any  exchange  and there is no public  trading  market for them.  The General
Partner is aware of certain transfers of Units between unrelated  parties,  some
of which are



                                      -18-

facilitated by secondary trading firms and matching  services.  In addition,  as
further  described  below,  the General Partner is aware of certain "4.9% tender
offers" which have been made for the Units.  The General  Partner  believes that
the transfers between unrelated parties have been limited and sporadic in number
and volume. Other than trades facilitated by certain secondary trading firms and
matching  services,  no  organized  trading  market for Units exists and none is
expected  to  develop.  Due to the  nature of these  transactions,  the  General
Partner has no verifiable  information regarding prices at which Units have been
transferred.  Further,  a transferee may not become a substitute Limited Partner
without the consent of the General Partner.

      Pursuant to the terms of the Partnership  Agreements,  the General Partner
is  obligated  to  annually  issue a  repurchase  offer  which  is  based on the
estimated future net revenues from the Partnerships'  reserves and is calculated
pursuant to the terms of the Partnership  Agreements.  Such repurchase  offer is
recalculated  monthly  in order to reflect  cash  distributions  to the  Limited
Partners and  extraordinary  events.  The following table sets forth the General
Partner's repurchase offer per Unit as of the periods indicated.  For purpose of
this Annual Report,  a Unit  represents an initial  subscription  of $1,000 to a
Partnership.

      The Partnership Agreements also provide for a right of presentment ("Right
of  Presentment")  whereby the General  Partner is required,  upon  request,  to
purchase up to 10% of a Partnership's  outstanding  Units at a price  calculated
pursuant to the terms of the Partnership Agreements and based on the liquidation
value of the limited  partnership  interest,  with a  reduction  for 70% of cash
distributions  that have been received prior to the transfer of the  partnership
interest. The following table sets forth the Right of Presentment price per Unit
as of the periods indicated.

      In addition to the  repurchase  offer and Right of  Presentment  described
above,  some of the Partnerships  have been subject to "4.9% tender offers" from
several  third  parties.  The General  Partner  does not know the terms of these
offers or the prices received by the Limited Partners who accepted these offers.


      Cash Distributions

      Cash  distributions  are primarily  dependent  upon a  Partnership's  cash
receipts from the sale of oil and gas  production and cash  requirements  of the
Partnership.  Distributable cash is determined by the General Partner at the end
of each calendar  quarter and distributed to the Limited Partners within 45 days
after the end of the quarter.  Distributions are restricted to cash on hand less
amounts  required  to be  retained  out of such cash as  determined  in the sole
judgment of the General  Partner to pay costs,  expenses,  or other  Partnership
obligations whether accrued or anticipated to accrue. In certain instances,  the
General  Partner may not distribute the full amount of cash receipts which might
otherwise be available  for  distribution  in an effort to equalize or stabilize
the amounts of quarterly  distributions.  Any available  amounts not distributed
are  invested  and the  interest  or income  thereon is for the  accounts of the
Limited Partners.

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

      Use of Forward-Looking Statements and Estimates

      This Annual Report contains certain forward-looking  statements. The words
"anticipate,"  "believe,"  "expect,"  "plan," "intend,"  "estimate,"  "project,"
"could," "may," and similar expressions are intended to identify forward-looking
statements.  Such statements reflect  management's current views with respect to
future  events and  financial  performance.  This Annual  Report  also  includes
certain information which is, or is based upon, estimates and assumptions.  Such
estimates and assumptions  are  management's  efforts to accurately  reflect the
condition and operation of the Partnerships.

      Use of  forward-looking  statements and estimates and assumptions  involve
risks and uncertainties which include, but are not limited to, the volatility of
oil and gas prices, the uncertainty of reserve  information,  the operating risk
associated with oil and gas properties  (including the risk of personal  injury,
death, property damage, damage to the well or producing reservoir, environmental
contamination,  and other  operating  risks),  the  prospect of changing tax and
regulatory laws, the availability and capacity of processing and  transportation
facilities,  the  general  economic  climate,  the  supply  and price of foreign
imports of oil and gas, the level of consumer product demand,  and the price and
availability  of  alternative  fuels.  Should  one or more  of  these  risks  or
uncertainties  occur  or  should  estimates  or  underlying   assumptions  prove
incorrect,  actual  conditions or results may vary materially and adversely from
those stated, anticipated, believed, estimated, or otherwise indicated.

      General Discussion

      The   following   general  discussion  should  be read in conjunction with
the  analysis of results of  operations  provided  below.  As  discussed  in the
"Results  of  Operations"  section  below,  volumes  of oil  and gas  sold  also
significantly  affect the  Partnerships'  revenues.  Oil and gas wells generally
produce  the  most  oil or gas in the  earlier  years of  their  lives  and,  as
production continues,  the rate of production naturally declines. At some point,
production physically ceases or becomes no longer economic. The Partnerships are
not acquiring additional oil and gas properties, and the existing properties are
not experiencing  significant  additional  production  through drilling or other
capital projects.  Therefore,  volumes of oil and gas produced naturally decline
from year to year.  While it is  difficult  for  management  to  predict  future
production  from  these  properties,  it is likely  that this  general  trend of
declining production will continue.



                                      -25-

      Despite this general trend of declining  production,  several  factors can
cause the volumes of oil and gas sold to increase or decrease at an even greater
rate over a given  period.  These factors  include,  but are not limited to, (i)
geophysical conditions which cause an acceleration of the decline in production,
(ii) the shutting in of wells (or the opening of previously  shut-in  wells) due
to low  oil  and gas  prices,  mechanical  difficulties,  loss  of a  market  or
transportation, or performance of workovers,  recompletions, or other operations
in the well, (iii) prior period volume adjustments (either positive or negative)
made by purchasers of the production,  (iv) ownership  adjustments in accordance
with  agreements  governing  the  operation  or  ownership  of the well (such as
adjustments  that occur at payout),  and (v)  completion  of  enhanced  recovery
projects which increase  production for the well. Many of these factors are very
significant as related to a single well or as related to many wells over a short
period  of  time.  However,  due to the  large  number  of  wells  owned  by the
Partnerships, these factors are generally not material as compared to the normal
decline in production experienced on all remaining wells.


      Results of Operations

      An  analysis  of the  change  in net oil and gas  operations  (oil and gas
sales,  less lease operating  expenses and production taxes) is presented in the
tables  following  "Results  of  Operations"  under the heading  "Average  Sales
Prices,  Production  Volumes,  and Average  Production  Costs."  Following  is a
discussion  of each  Partnership's  results  of  operations  for the year  ended
December  31, 2000 as compared to the year ended  December  31, 1999 and for the
year ended December 31, 1999 as compared to the year ended December 31, 1998.

                      Year Ended December 31, 2000 Compared
                         to Year Ended December 31, 1999
                      -------------------------------------

      Total oil and gas sales increased  $506,330 (65.6%) in 2000 as compared to
1999. Of this increase,  approximately $97,000 and $484,000,  respectively, were
related to increases in the average  prices of oil and gas sold.  Volumes of oil
and gas sold decreased  2,837 barrels and 17,207 Mcf,  respectively,  in 2000 as
compared to 1999.  The decrease in volumes of oil sold was  primarily due to (i)
normal declines in production and (ii) a positive prior period volume adjustment
on one  significant  well during 1999.  Average oil and gas prices  increased to
$31.27  per  barrel  and $3.71 per Mcf,  respectively,  in 2000 from  $14.01 per
barrel and $2.08 per Mcf, respectively, in 1999.

      Oil and gas production  expenses  (including lease operating  expenses and
production  taxes)  increased  $59,243 (37.1%) in 2000 as compared to 1999. This
increase was primarily due to (i) workover  expenses incurred on one significant
well during 2000 in order to improve the recovery of reserves,  (ii) an increase
in production taxes associated with the increase in oil and gas sales, and (iii)
a negative prior period lease operating expense  adjustment made by the operator
on one significant well during 1999. As a percentage of oil and gas sales, these
expenses decreased to 17.1% in 2000 from 20.7% in 1999. This percentage decrease
was primarily due to the increases in the average prices of oil and gas sold.

      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
decreased  $23,739  (27.8%)  in 2000 as  compared  to 1999.  This  decrease  was
primarily due to (i) one significant  well being fully depleted in 1999 due to a
lack of remaining  economically  recoverable  reserves and (ii) the decreases in
volumes of oil and gas sold. As a percentage of oil and gas sales,  this expense
decreased  to 4.8% in 2000 from  11.1% in 1999.  This  percentage  decrease  was
primarily due to the increases in the average prices of oil and gas sold.

      General and  administrative  expenses  increased  $1,925 (2.1%) in 2000 as
compared to 1999. As a percentage of oil and gas sales, these expenses decreased
to 7.2% in 2000 from 11.7% in 1999. This  percentage  decrease was primarily due
to the increase in oil and gas sales.

      The Limited Partners have received cash distributions through December 31,
2000  totaling   $15,115,175  or  210.09%  of  the  Limited   Partners'  capital
contributions.



                      Year Ended December 31, 1999 Compared
                         to Year Ended December 31, 1998
                      -------------------------------------

      Total oil and gas sales decreased  $289,917 (27.3%) in 1999 as compared to
1998. Of this decrease,  approximately $35,000 and $287,000,  respectively, were
related to decreases in volumes of oil and gas sold. Volumes of oil and gas sold
decreased  2,767 barrels and 142,185 Mcf,  respectively,  in 1999 as compared to
1998.  The  decrease  in volumes  of oil sold was  primarily  due to  production
difficulties on one significant well during 1999. The decrease in volumes of gas
sold was primarily due to (i) production  difficulties on one  significant  well
during 1999, (ii) positive prior period volume adjustments made by the operators
on two  significant  wells during 1998, and (iii) normal declines in production.
Average  oil and gas  prices  increased  to $14.01 per barrel and $2.08 per Mcf,
respectively, in 1999 from $12.55 per barrel and $2.02 per Mcf, respectively, in
1998.

      The I-D  Partnership  sold certain oil and gas properties  during 1999 and
recognized  a $494 gain on such sales.  Sales of oil and gas  properties  during
1998  resulted  in  the  I-D  Partnership  recognizing  similar  gains  totaling
$260,624.

      Oil and gas production  expenses  (including lease operating  expenses and
production  taxes)  decreased  $74,929 (32.0%) in 1999 as compared to 1998. This
decrease was primarily due to (i) a decrease in production taxes associated with
the decrease in oil and gas sales,  (ii) a decrease in lease operating  expenses
associated  with the  decreases  in  volumes  of oil and gas  sold,  and (iii) a
negative prior period lease operating expense adjustment made by the operator on
one  significant  well during 1999. As a percentage of oil and gas sales,  these
expenses decreased to 20.7% in 1999 from 22.1% in 1998.

      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
decreased  $12,444  (12.7%)  in 1999 as  compared  to 1998.  This  decrease  was
primarily  due to (i) the  decreases  in  volumes  of oil and gas  sold and (ii)
upward  revisions in the estimates of remaining oil and gas reserves at December
31, 1999.  These decreases were partially  offset by one significant  well being
fully  depleted in 1999 due to the lack of  remaining  economically  recoverable
reserves.  As a percentage of oil and gas sales, this expense increased to 11.1%
in 1999 from 9.2% in 1998.  This  percentage  increase was  primarily due to the
depreciation,  depletion, and amortization expense on the well fully depleted in
1999.

      General and administrative  expenses remained  relatively constant in 1999
as  compared  to 1998.  As a  percentage  of oil and gas sales,  these  expenses
increased  to 11.7% in 1999  from 8.5% in 1998.  This  percentage  increase  was
primarily due to the decrease in oil and gas sales.

      Total oil and gas sales increased  $2,657,820  (63.9%) in 2000 as compared
to 1999. Of this increase, approximately $605,000 and $2,261,000,  respectively,
were related to increases in the average prices of oil and gas sold.  Volumes of
oil and gas sold decreased 6,296 barrels and 50,058 Mcf,  respectively,  in 2000
as compared to 1999.  The decrease in volumes of oil sold was  primarily  due to
normal  declines in production.  Average oil and gas prices  increased to $28.23
per barrel and $3.59 per Mcf,  respectively,  in 2000 from $16.63 per barrel and
$2.07 per Mcf, respectively, in 1999.

      As  discussed  in  "Liquidity  and  Capital   Resources"  below,  the  I-E
Partnership  recognized an insurance settlement in the amount of $675,000 during
1999. No similar settlements occurred during 2000.

      Oil and gas production  expenses  (including lease operating  expenses and
production  taxes) increased  $288,581 (25.0%) in 2000 as compared to 1999. This
increase was  primarily due to (i) an increase in  production  taxes  associated
with the  increase  in oil and gas sales,  (ii)  workover  expenses  incurred on
several  wells  during 2000 in order to improve the  recovery of  reserves,  and
(iii) an increase in legal  expenses  incurred  on one  significant  well during
2000. As a percentage of oil and gas sales, these expenses decreased to 21.2% in
2000 from 27.7% in 1999.  This  percentage  decrease  was  primarily  due to the
increases in the average prices of oil and gas sold.

      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
decreased  $150,809  (23.1%) in 2000 as  compared  to 1999.  This  decrease  was
primarily due to (i) several wells being fully depleted in 1999 due to a lack of
remaining  economically  recoverable  reserves,  (ii)  upward  revisions  in the
estimates  of  remaining  gas  reserves  at  December  31,  2000,  and (iii) the
decreases in volumes of oil and gas sold.  As a percentage of oil and gas sales,
this  expense  decreased  to 7.4% in 2000 from  15.7% in 1999.  This  percentage
decrease was primarily due to the increases in the average prices of oil and gas
sold.

      General and administrative  expenses remained  relatively constant in 2000
as  compared  to 1999.  As a  percentage  of oil and gas sales,  these  expenses
decreased  to 7.6% in 2000 from  12.5% in 1999.  This  percentage  decrease  was
primarily due to the increase in oil and gas sales.

      The Limited Partners have received cash distributions through December 31,
2000  totaling   $58,675,552  or  140.24%  of  the  Limited   Partners'  capital
contributions.

                         to Year Ended December 31, 1998
                      -------------------------------------

      Total oil and gas sales  decreased  $449,705 (9.8%) in 1999 as compared to
1998. Of this decrease,  approximately $70,000 and $907,000,  respectively, were
related  to  decreases  in  volumes of oil and gas sold.  These  decreases  were
partially   offset  by  increases  of   approximately   $272,000  and  $255,000,
respectively,  related to increases  in the average  prices of oil and gas sold.
Volumes  of  oil  and  gas  sold  decreased   5,881  barrels  and  475,973  Mcf,
respectively,  in 1999 as compared to 1998.  The decrease in volumes of gas sold
was primarily due to (i) positive prior



                                      -29-
<PAGE>



period volume  adjustments  made by the  purchasers on several wells during 1998
and (ii) normal declines in production.  Average oil and gas prices increased to
$16.63  per  barrel  and $2.07 per Mcf,  respectively,  in 1999 from  $11.98 per
barrel and $1.90 per Mcf, respectively, in 1998.

      The I-E  Partnership  sold certain oil and gas properties  during 1999 and
recognized a $1,587 gain on such sales.  Sales of oil and gas properties  during
1998  resulted  in  the  I-E  Partnership  recognizing  similar  gains  totaling
$1,154,155.

      As  discussed  in  "Liquidity  and  Capital   Resources"  below,  the  I-E
Partnership  recognized an insurance settlement in the amount of $675,000 during
1999. No similar settlements occurred during 1998.

      Oil and gas production  expenses  (including lease operating  expenses and
production  taxes) decreased  $352,907 (23.4%) in 1999 as compared to 1998. This
decrease  was  primarily  due to (i) a  decrease  in  lease  operating  expenses
associated with the decreases in volumes of oil and gas sold, (ii) a decrease in
production  taxes  associated with the decrease in oil and gas sales,  and (iii)
workover  expenses  incurred  on one  significant  well  during 1998 in order to
improve the recovery of reserves.  As a percentage  of oil and gas sales,  these
expenses decreased to 27.7% in 1999 from 32.7% in 1998. This percentage decrease
was primarily due to the increases in the average prices of oil and gas sold.

      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
decreased  $104,218  (13.8%) in 1999 as  compared  to 1998.  This  decrease  was
primarily  due to the decreases in volumes of oil and gas sold,  which  decrease
was partially offset by several wells being fully depleted in 1999 due to a lack
of remaining  economically  recoverable reserves. As a percentage of oil and gas
sales, this expense decreased to 15.7% in 1999 from 16.4% in 1998.

      The I-E  Partnership  recognized  a non-cash  charge  against  earnings of
$547,048 in the fourth  quarter of 1998.  This charge was  necessary  due to the
unamortized  costs of one field  exceeding  the expected  future cash flows from
that field. No similar charge was necessary in 1999.

      General and administrative  expenses remained  relatively constant in 1999
as  compared  to 1998.  As a  percentage  of oil and gas sales,  these  expenses
increased  to 12.5% in 1999 from 11.2% in 1998.  This  percentage  increase  was
primarily due to the decrease in oil and gas sales.

      Total oil and gas sales increased  $730,849 (56.6%) in 2000 as compared to
1999. Of this increase,  approximately $294,000 and $555,000, respectively, were
related to increases in the average prices of oil and gas sold.  These increases
were  partially  offset by a  decrease  of  approximately  $74,000  related to a
decrease  in volumes of gas sold.  Volumes of oil and gas sold  decreased  2,689
barrels and 33,856 Mcf, respectively,  in 2000 as compared to 1999. The decrease
in volumes  of oil sold was  primarily  due to normal  declines  in  production.
Average  oil and gas  prices  increased  to $28.39 per barrel and $3.77 per Mcf,
respectively, in 2000 from $16.68 per barrel and $2.17 per Mcf, respectively, in
1999.

      As  discussed  in  "Liquidity  and  Capital   Resources"  below,  the  I-F
Partnership  recognized an insurance settlement in the amount of $472,500 during
1999. No similar settlements occurred during 2000.

      Oil and gas production  expenses  (including lease operating  expenses and
production  taxes) increased  $104,507 (24.6%) in 2000 as compared to 1999. This
increase was  primarily due to (i) an increase in  production  taxes  associated
with the  increase  in oil and gas sales,  (ii)  workover  expenses  incurred on
several  wells  during 2000 in order to improve the  recovery of  reserves,  and
(iii) an increase in legal  expenses  incurred  on one  significant  well during
2000. As a percentage of oil and gas sales, these expenses decreased to 26.2% in
2000 from 32.9% in 1999.  This  percentage  decrease  was  primarily  due to the
increases in the average prices of oil and gas sold.

      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
decreased  $68,736  (31.0%)  in 2000 as  compared  to 1999.  This  decrease  was
primarily due to (i) several wells being fully depleted in 1999 due to a lack of
remaining economically recoverable reserves and (ii) the decreases in volumes of
oil and gas sold. As a percentage of oil and gas sales,  this expense  decreased
to 7.6% in 2000 from 17.2% in 1999. This  percentage  decrease was primarily due
to the increases in the average prices of oil and gas sold

      General and  administrative  expenses  increased  $1,738 (1.0%) in 2000 as
compared to 1999. As a percentage of oil and gas sales, these expenses decreased
to 8.9% in 2000 from 13.8% in 1999. This  percentage  decrease was primarily due

      Total oil and gas sales decreased  $150,641 (10.4%) in 1999 as compared to
1998. Of this decrease,  approximately $29,000 and $302,000,  respectively, were
related  to  decreases  in  volumes of oil and gas sold.  These  decreases  were
partially   offset  by   increases  of   approximately   $127,000  and  $53,000,
respectively,  related to increases  in the average  prices of oil and gas sold.
Volumes  of  oil  and  gas  sold  decreased   2,409  barrels  and  148,722  Mcf,
respectively,  in 1999 as compared to 1998.  The decrease in volumes of gas sold
was primarily due to (i) positive  prior period volume  adjustments  made by the
purchasers on several wells during 1998 and (ii) normal  declines in production.
Average  oil and gas  prices  increased  to $16.68 per barrel and $2.17 per Mcf,
respectively, in 1999 from $12.10 per barrel and $2.03 per Mcf, respectively, in
1998.

      The I-F  Partnership  sold certain oil and gas properties  during 1999 and
recognized  a $546 gain on such sales.  Sales of oil and gas  properties  during
1998  resulted  in  the  I-F  Partnership  recognizing  similar  gains  totaling
$380,920.

      As  discussed  in  "Liquidity  and  Capital   Resources"  below,  the  I-F
Partnership  recognized an insurance settlement in the amount of $472,500 during
1999. No similar settlements occurred during 1998.

      Oil and gas production  expenses  (including lease operating  expenses and
production  taxes) decreased  $242,970 (36.4%) in 1999 as compared to 1998. This
decrease  was  primarily  due to (i) a  decrease  in  lease  operating  expenses
associated  with the decreases in volumes of oil and gas sold,(ii) a decrease in
production  taxes  associated with the decrease in oil and gas sales,  and (iii)
workover  expenses incurred on several wells during 1998 in order to improve the
recovery of  reserves.  As a  percentage  of oil and gas sales,  these  expenses
decreased  to 32.9% in 1999 from 46.3% in 1998.  This  percentage  decrease  was
primarily due to the increases in the average prices of oil and gas sold and the
1998 workover expenses.

      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
decreased  $32,683  (12.8%)  in 1999 as  compared  to 1998.  This  decrease  was
primarily  due to the decreases in volumes of oil and gas sold,  which  decrease
was partially offset by several wells being fully depleted in 1999 due to a lack
of remaining



                                      -32-

economically  recoverable  reserves.  As a percentage of oil and gas sales, this
expense decreased to 17.2% in 1999 from 17.7% in 1998.

      The I-F  Partnership  recognized  a non-cash  charge  against  earnings of
$382,925 in the fourth  quarter of 1998.  This charge was  necessary  due to the
unamortized  costs of one field  exceeding  the expected  future cash flows from
that field. No similar charge was necessary in 1999.

      General and administrative  expenses remained  relatively constant in 1999
as  compared  to 1998.  As a  percentage  of oil and gas sales,  these  expenses
increased  to 13.8% in 1999 from 12.3% in 1998.  This  percentage  increase  was
primarily due to the decrease in oil and gas sales.



      Average Sales Prices, Production Volumes and Average Production Costs

      The following  tables are  comparisons  of the annual  average oil and gas
sales prices,  production volumes, and average production costs (lease operating
expenses and production taxes) per equivalent unit (one barrel of oil or six Mcf
of gas) for 2000, 1999, and 1998.

      Liquidity and Capital Resources

      Net  proceeds  from  operations  less  necessary  operating  capital are
distributed  to the  Limited  Partners  on a  quarterly  basis.  See  "Item 5.
Market for Units and Related Limited  Partner  Matters." The net proceeds from
production are not reinvested in



                                      -35-
<PAGE>



productive  assets,  except to the extent that producing wells are improved,  or
where  methods  are  employed  to permit more  efficient  recovery of  reserves,
thereby resulting in a positive economic impact. Assuming 2000 production levels
for future years, the  Partnerships'  proved reserve  quantities at December 31,
2000 would have the following remaining lives:


                  Partnership       Gas-Years      Oil-Years
                  -----------       ---------      ---------

                      I-F              7.5            8.4

These life of reserves estimates are based on the current estimates of remaining
oil and gas reserves. See "Item 2. Properties" for a discussion of these reserve
estimates.  Any  decrease  from the high oil and gas prices at December 31, 2000
may cause a decrease in the estimated life of said reserves.

      The   Partnerships'   available   capital   from  the  Limited   Partners'
subscriptions  has been spent on oil and gas  properties  and there should be no
further material capital resource commitments for any of the Partnerships in the
future.  Occasional  expenditures  by the  Partnerships  for new  wells  or well
recompletions or workovers,  however, may reduce or eliminate cash available for
a  particular  quarterly  cash  distribution.  The  Partnerships  have  no  debt
commitments.  Cash for operational  purposes will be provided by current oil and
gas production.

      The  Partnerships  sold certain oil and gas properties  during 2000, 1999,
and  1998.  The sale of the  Partnerships'  properties  was made by the  General
Partner after giving due  consideration  to both the offer price and the General
Partner's  estimate  of the  property's  remaining  proved  reserves  and future
operating costs. Net proceeds from the sale of any such properties were included
in the  calculation  of the  Partnerships'  cash  distributions  for the quarter
immediately following the Partnerships'  receipt of the proceeds.  The amount of
such proceeds from the sale of oil and gas  properties  during 2000,  1999,  and
1998, were as follows:


            Partnership         2000         1999         1998

                I-E            119,626       2,695      1,265,357

      The General  Partner  believes that the sale of these  properties  will be
beneficial  to the  Partnerships  in the  long-term  since the  properties  sold
generally had a higher ratio of



                                      -36-

future  operating  expenses as compared to reserves  than the  properties  not
sold.

      In August 1999, the I-E and I-F Partnerships received insurance settlement
proceeds in the amounts of $675,000 and  $472,500,  respectively,  for the costs
incurred  to drill  the  State  Lease  8191 No.  4 well in St.  Bernard  Parish,
Louisiana for the purpose of relieving pressure in another well which suffered a
blowout  during a workover  attempt.  This new well was completed as a producing
gas  well  in  1998.  The  insurance  proceeds  amounts  were  included  in  the
Partnerships' August 1999 cash distribution.

      There can be no  assurance  as to the amount of the  Partnerships'  future
cash distributions. The Partnerships' ability to make cash distributions depends
primarily upon the level of available  cash flow generated by the  Partnerships'
operating  activities,  which will be affected (either positively or negatively)
by many factors beyond the control of the  Partnerships,  including the price of
and demand for oil and gas and other  market and  economic  conditions.  Even if
prices and costs remain stable,  the amount of cash available for  distributions
will decline over time (as the volume of production  from  producing  properties
declines)  since  the   Partnerships  are  not  replacing   production   through
acquisitions of producing properties and drilling. The Partnerships' quantity of
proved  reserves  has  been  reduced  by the sale of oil and gas  properties  as
described above;  therefore,  it is possible that the Partnerships'  future cash
distributions  will  decline  as a result of a  reduction  of the  Partnerships'
reserve base.

      Pursuant  to the terms of the  Partnership  Agreements,  the  Partnerships
would have terminated on December 31, 1999. However, the Partnership  Agreements
provide that the General Partner may extend the term of each  Partnership for up
to five periods of two years each. The General Partner has extended the terms of
the Partnerships for the first two year extension period to December 31, 2001.


      Inflation and Changing Prices

      Prices obtained for oil and gas production  depend upon numerous  factors,
including the extent of domestic and foreign production, foreign imports of oil,
market  demand,  domestic  and  foreign  economic  conditions  in  general,  and
governmental  regulations  and tax laws.  The general  level of inflation in the
economy did not have a material effect on the operations of the  Partnerships in
2000. Oil and gas prices have fluctuated  during recent years and generally have
not followed the same pattern as  inflation.  See "Item 2.  Properties - Oil and
Gas Production, Revenue, and Price History."

      Section 16(a) Beneficial Ownership Reporting Compliance

      To the knowledge of the Partnerships  and the General Partner,  there were
no officers,  directors, or ten percent owners who were delinquent filers during
2000 of reports  required  under  Section 16 of the  Securities  Exchange Act of
1934.


ITEM 11.    EXECUTIVE COMPENSATION

      The General  Partner and its  affiliates are reimbursed for actual general
and  administrative  costs and operating costs incurred and  attributable to the
conduct of the business affairs and operations of the Partnerships,  computed on
a cost basis,  determined  in  accordance  with  generally  accepted  accounting
principles.  Such reimbursed  costs and expenses  allocated to the  Partnerships
include office rent, secretarial, employee compensation and benefits, travel and
communication costs, fees for professional  services,  and other items generally
classified  as general or  administrative  expense.  When actual costs  incurred
benefit other  Partnerships and affiliates,  the allocation of costs is based on
the  relationship of the  Partnerships'  reserves to the total reserves owned by
all  Partnerships  and  affiliates.  The  amount of general  and  administrative
expense allocated to the General Partner and its affiliates which was charged to
each  Partnership  for 2000,  1999,  and 1998,  is set forth in the table below.
Although the actual  costs  incurred by the General  Partner and its  affiliates
have  fluctuated  during the three years  presented,  the amount  charged to the
Partnerships have not fluctuated every year due to expense  limitations  imposed
by the Partnership Agreements.

      None  of  the  officers  or  directors  of  the  General  Partner  receive
compensation  directly from the  Partnerships.  The  Partnerships  reimburse the
General  Partner  or its  affiliates  for that  portion  of such  officers'  and
directors'   salaries  and  expenses   attributable  to  time  devoted  by  such
individuals to the

      Affiliates  of  the  Partnerships   serve  as  operator  of  some  of  the
Partnerships'  wells.  The General  Partner  contracts with such  affiliates for
services as operator of the wells. As operator,  such affiliates are compensated
at rates  provided  in the  operating  agreements  in effect and  charged to all
parties to such agreement. Such compensation may occur both prior and subsequent
to the  commencement  of  commercial  marketing of production of oil or gas. The
dollar amount of such compensation paid by the Partnerships to the affiliates is
impossible to quantify as of the date of this Annual Report.

      Samson  maintains  necessary  inventories of new and used field equipment.
Samson  may  have  provided  some of this  equipment  for  wells  in  which  the
Partnerships  have an interest.  This  equipment was provided at prices or rates
equal  to or  less  than  those  normally  charged  in the  same  or  comparable
geographic  area by unaffiliated  persons or companies  dealing at arm's length.
The operators of these wells billed the Partnerships for a portion of such costs
based upon the Partnerships' interest in the well.

ITEM 12.    SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

      The following table provides information as to the beneficial ownership of
the Units as of February 1, 2001 by (i) each beneficial  owner of more than five
percent of the issued and outstanding  Units, (ii) the directors and officers of
the General  Partner,  and (iii) the General  Partner  and its  affiliates.  The
address of each of such persons is Samson Plaza, Two West Second Street,  Tulsa,
Oklahoma 74103.

   Partner as a group and
   the General Partner (4 persons)                   3,644      (25.4%)



ITEM 13.    CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

      The General  Partner and certain of its  affiliates  engage in oil and gas
activities  independently  of the  Partnerships  which  result in  conflicts  of
interest that cannot be totally  eliminated.  The allocation of acquisition  and
drilling  opportunities and the nature of the compensation  arrangements between
the  Partnerships  and the General  Partner also create  potential  conflicts of
interest.  An affiliate of the Partnerships owns some of the Partnerships' Units
and  therefore  has an identity of interest  with other  Limited  Partners  with
respect to the operations of the Partnerships.

      In order to attempt to assure  limited  liability for Limited  Partners as
well as an orderly  conduct  of  business,  management  of the  Partnerships  is
exercised  solely by the General Partner.  The Partnership  Agreements grant the
General Partner broad discretionary  authority with respect to the Partnerships'
participation  in  drilling  prospects  and  expenditure  and  control of funds,
including  borrowings.  These  provisions  are  similar  to those  contained  in
prospectuses   and   partnership   agreements  for  other  public  oil  and  gas
partnerships.  Broad  discretion as to general  management  of the  Partnerships
involves  circumstances  where the General Partner has conflicts of interest and
where  it  must  allocate  costs  and  expenses,  or  opportunities,  among  the
Partnerships and other competing interests.

      The  General  Partner  does  not  devote  all of its  time,  efforts,  and
personnel exclusively to the Partnerships.  Furthermore, the Partnerships do not
have  any  employees,   but  instead  rely  on  the  personnel  of  Samson.  The
Partnerships thus compete with Samson (including other oil and gas partnerships)



                                      -45-
<PAGE>



for the time and  resources  of such  personnel.  Samson  devotes  such time and
personnel  to  the  management  of the  Partnerships  as  are  indicated  by the
circumstances and as are consistent with the General Partner's fiduciary duties.

      Affiliates of the Partnerships are solely responsible for the negotiation,
administration,  and  enforcement of oil and gas sales  agreements  covering the
Partnerships'  leasehold  interests.  Because affiliates of the Partnerships who
provide  services to the  Partnerships  have  fiduciary or other duties to other
members of Samson,  contract amendments and negotiating  positions taken by them
in their  effort  to  enforce  contracts  with  purchasers  may not  necessarily
represent  the  positions  that  the  Partnerships  would  take if they  were to
administer their own contracts without involvement with other members of Samson.
On the  other  hand,  management  believes  that the  Partnerships'  negotiating
strength  and  contractual  positions  have  been  enhanced  by  virtue of their
affiliation with Samson.

      In our opinion,  the accompanying  combined balance sheets and the related
combined  statements of operations,  changes in partners'  capital (deficit) and
cash flows present  fairly,  in all material  respects,  the combined  financial
position of the  Geodyne  Energy  Income  Limited  Partnership  I-D, an Oklahoma
limited partnership, and Geodyne Production Partnership I-D, an Oklahoma general
partnership,  at December 31, 2000 and 1999,  and the combined  results of their
operations  and their cash flows for each of the three years in the period ended
December 31, 2000, in conformity with accounting  principles  generally accepted
in  the  United  States  of  America.   These   financial   statements  are  the
responsibility of the Partnerships' management; our responsibility is to express
an opinion on these financial  statements based on our audits.  We conducted our
audits of these  financial  statements  in accordance  with  auditing  standards
generally  accepted in the United States of America,  which require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement.  An audit 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, and evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for the opinion  expressed
above.

TO THE PARTNERS

GEODYNE ENERGY INCOME LIMITED PARTNERSHIP I-E
GEODYNE PRODUCTION PARTNERSHIP I-E

      In our opinion,  the accompanying  combined balance sheets and the related
combined  statements of operations,  changes in partners'  capital (deficit) and
cash flows present  fairly,  in all material  respects,  the combined  financial
position of the  Geodyne  Energy  Income  Limited  Partnership  I-E, an Oklahoma
limited partnership, and Geodyne Production Partnership I-E, an Oklahoma general
partnership,  at December 31, 2000 and 1999,  and the combined  results of their
operations  and their cash flows for each of the three years in the period ended
December 31, 2000, in conformity with accounting  principles  generally accepted
in  the  United  States  of  America.   These   financial   statements  are  the
responsibility of the Partnerships' management; our responsibility is to express
an opinion on these financial  statements based on our audits.  We conducted our
audits of these  financial  statements  in accordance  with  auditing  standards
generally  accepted in the United States of America,  which require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement.  An audit 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, and evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for the opinion  expressed
above.

TO THE PARTNERS

GEODYNE ENERGY INCOME LIMITED PARTNERSHIP I-F
GEODYNE PRODUCTION PARTNERSHIP I-F

      In our opinion,  the accompanying  combined balance sheets and the related
combined  statements of operations,  changes in partners'  capital (deficit) and
cash flows present  fairly,  in all material  respects,  the combined  financial
position of the  Geodyne  Energy  Income  Limited  Partnership  I-F, an Oklahoma
limited partnership, and Geodyne Production Partnership I-F, an Oklahoma general
partnership,  at December 31, 2000 and 1999,  and the combined  results of their
operations  and their cash flows for each of the three years in the period ended
December 31, 2000, in conformity with accounting  principles  generally accepted
in  the  United  States  of  America.   These   financial   statements  are  the
responsibility of the Partnerships' management; our responsibility is to express
an opinion on these financial  statements based on our audits.  We conducted our
audits of these  financial  statements  in accordance  with  auditing  standards
generally  accepted in the United States of America,  which require that we plan
and perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement.  An audit 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, and evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for the opinion  expressed
above.

              GEODYNE ENERGY INCOME PROGRAM I LIMITED PARTNERSHIPS
                   Notes to the Combined Financial Statements
             For the Years Ended December 31, 2000, 1999, and 1998


1.    ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      Organization and Nature of Operations

      The Geodyne Energy Income Limited  Partnerships (the  "Partnerships") were
formed  pursuant  to a public  offering  of  depositary  units  ("Units").  Upon
formation,  investors became limited partners (the "Limited  Partners") and held
Units issued by each Partnership. Geodyne Resources, Inc. is the general partner
of the  Partnerships.  Each  Partnership  is a general  partner  in the  related
Geodyne Energy Income  Production  Partnership  (collectively,  the  "Production
Partnership") in which Geodyne  Resources,  Inc. serves as the managing partner.
Limited Partner capital contributions were contributed to the related Production
Partnerships   for  investment  in  producing  oil  and  gas   properties.   The
Partnerships  were activated on the following  dates with the following  Limited
Partner capital contributions:

                                                         Limited
                                                         Partner
                                    Date of              Capital
            Partnership           Activation          Contributions
            -----------       ------------------      --------------

               I-D            March 4, 1986            $ 7,194,700
               I-E            September 10, 1986        41,839,400
               I-F            December 16, 1986         14,320,900

      The  Partnerships'  original  termination  date  under  their  partnership
agreements was December 31, 1999. The General  Partner has extended the terms of
the  Partnerships  for a two year  period to December  31, 2001  pursuant to its
right to extend the term of each Partnership for up to five periods of two years
each.

      For  purposes  of  these  financial   statements,   the  Partnerships  and
Production  Partnerships are collectively  referred to as the "Partnerships" and
the general  partner and managing  partner are  collectively  referred to as the
"General Partner."

      An affiliate of the General  Partner owned the following Units at December
31, 2000:



                                     -F19-

                               Number of        Percent of
            Partnership       Units Owned    Outstanding Units
            -----------       -----------    -----------------
               I-D               1,417             19.7%
               I-E               9,133             21.8%
               I-F               3,644             25.4%

      The  Partnerships'  sole business is the development and production of oil
and gas.  Substantially  all of the  Partnerships'  gas  reserves are being sold
regionally  on the "spot  market." Due to the highly  competitive  nature of the
spot market, prices on the spot market are subject to wide seasonal and regional
pricing  fluctuations.  In  addition,  such  spot  market  sales  are  generally
short-term in nature and are dependent  upon obtaining  transportation  services
provided  by  pipelines.   The   Partnerships'  oil  is  sold  at  or  near  the
Partnerships'   wells  under   short-term   purchase   contracts  at  prevailing
arrangements  which are customary in the oil industry.  The prices  received for
the  Partnerships'  oil  and gas  are  subject  to  influences  such  as  global
consumption and supply trends.


      Allocation of Costs and Revenues

      The combination of the allocation provisions in each Partnership's limited
partnership  agreement and each Production  Partnership's  partnership agreement
(collectively,  the "Partnership Agreement") results in allocations of costs and
income between the Limited Partners and General Partner as follows:

(1)   Payout occurs when total  distributions  to Limited  Partners  equal total
      original Limited Partner subscriptions.
(2)   The allocations in the table result  generally from the combined effect of
      the allocation provisions in the Partnership Agreements.  For example, the
      costs  incurred in  development  drilling  are  allocated  90.9091% to the
      limited  partnership  and 9.0909% to the  managing  partner.  The 90.9091%
      portion of these costs allocated to the limited  partnership,  when passed
      through the limited  partnership,  is further allocated 99% to the limited
      partners  and 1% to the  general  partner.  In  this  manner  the  Limited
      Partners  are  allocated  90% of such  costs and the  General  Partner  is
      allocated 10% of such costs.
(3)   Distributions  of cash and the above allocation of income and costs of the
      General  Partner  are  subject  to  subordination  during  the  first  two
      twelve-month  "allocation  periods".  The first  twelve-month  "allocation
      period"  commenced on the last day of the first full fiscal  quarter after
      the  earlier  of (i) the  date on  which  90% of a  limited  partnership's
      capital contribution to a Production Partnership has been expended or (ii)
      two  years  after  activation  of a  Production  Partnership.  The  second
      twelve-month  "allocation  period"  commenced  at the  end  of  the  first
      allocation  period.  To the extent that the amount of cash  distributed in
      the allocation  periods is insufficient to permit the Limited  Partners to
      receive a 15% cumulative (but not compounded) twelve-month return on their
      capital  contributions,  up to one-half of the managing partners' share of
      distributable  cash after each such allocation period, and a corresponding
      amount of their allocable share of income and costs,  shall  thereafter be
      allocated  to permit  the  Limited  Partners  to  receive,  to the  extent
      available,  the aggregate amount of such deficiency.  After the allocation
      periods,  the managing partner may recoup amounts previously  allocated to
      the Limited  Partners  pursuant  to this  subordination  provision  to the
      extent  income is  otherwise  sufficient  to permit  Limited  Partners  to
      receive at least a 15% cumulative (but not compounded) twelve-month return
      since the commencement of the allocation periods.

      The I-D  Partnership  achieved  payout  in late  1991  and the I-E and I-F
Partnerships  achieved  payout during the second quarter of 1995.  After payout,
operations  were allocated  using the after payout  percentages set forth in the
table above.


      Basis of Presentation

      These  financial   statements   reflect  the  combined  accounts  of  each
Partnership  after the  elimination of all  inter-partnership  transactions  and
balances.


      Cash and Cash Equivalents

      The Partnerships consider all highly liquid investments with a maturity of
three months or less when purchased to be cash equivalents. Cash equivalents are
not insured, which cause the Partnerships to be subject to risk.


      Credit Risk

      Accrued  oil and gas sales  which  are due from a  variety  of oil and gas
purchasers  subject the  Partnerships to a concentration of credit risk. Some of
these purchasers are discussed in Note 3 - Major Customers.


      Oil and Gas Properties

      The  Partnerships  follow the successful  efforts method of accounting for
their  oil  and  gas  properties.  Under  the  successful  efforts  method,  the
Partnerships  capitalize all property  acquisition  costs and development  costs
incurred in  connection  with the further  development  of oil and gas reserves.
Property  acquisition  costs include costs incurred by the  Partnerships  or the
General  Partner  to  acquire  producing  properties,  including  related  title
insurance or examination costs, commissions,  engineering,  legal and accounting
fees, and similar costs directly related to the acquisitions,  plus an allocated
portion of the General Partner's  property screening costs. The acquisition cost
to the Partnerships of properties acquired by the General Partner is adjusted to
reflect  the net cash  results of  operations,  including  interest  incurred to
finance the  acquisition,  for the period of time the properties are held by the
General Partner. Leasehold impairment of unproved properties is recognized based
upon  an  individual  property  assessment  and  exploratory  experience.   Upon
discovery of commercial  reserves,  leasehold costs are transferred to producing
properties.




                                     -F22-
<PAGE>




      Depletion of the cost of producing oil and gas properties, amortization of
related intangible  drilling and development costs, and depreciation of tangible
lease and well  equipment are computed on the  units-of-production  method.  The
Partnerships' depletion,  depreciation,  and amortization includes dismantlement
and  abandonment  costs,  net of  estimated  salvage  value.  The  depreciation,
depletion,  and amortization  rates per equivalent barrel of oil produced during
the years ended December 31, 2000, 1999, and 1998, were as follows:

            Partnership        2000        1999        1998
            -----------       ------      ------      ------

                I-D           $1.12       $1.41       $1.12
                I-E            1.67        2.07        1.89
                I-F            1.85        2.43        2.15


      When complete units of depreciable property are retired or sold, the asset
cost and related  accumulated  depreciation are eliminated with any gain or loss
reflected in income.  When less than complete units of depreciable  property are
retired or sold, the proceeds are credited to oil and gas properties.

      The  Partnerships  evaluate the  recoverability  of the carrying  costs of
their proved oil and gas properties at the field level. If the unamortized costs
of oil and gas properties within a field exceed the expected undiscounted future
cash flows from such  properties,  the cost of the properties is written down to
fair value,  which is determined by using the discounted  future cash flows from
the  properties.  During 1998, the I-E and I-F  Partnerships  recorded  non-cash
charges  against  earnings  (impairment  provisions)  of $547,048 and  $382,925,
respectively.  No other impairment  provisions were recorded by the Partnerships
during the three years ended December 31, 2000.  The risk that the  Partnerships
will be required to record similar impairment provisions in the future increases
as oil and gas prices decrease.


      Deferred Charge

      The Deferred Charge represents costs deferred for lease operating expenses
incurred  in  connection  with the  Partnerships'  underproduced  gas  imbalance
positions.  The rate used in calculating  the deferred  charge is the average of
the annual  production costs per Mcf. At December 31, 2000 and 1999,  cumulative
total gas sales volumes for underproduced wells were less than the Partnerships'
pro-rata  share  of total  gas  production  from  these  wells by the  following
amounts:

                                 2000                       1999

      Accrued Liability

      The Accrued  Liability  represents  charges  accrued  for lease  operating
expenses  incurred  in  connection  with  the  Partnerships'   overproduced  gas
imbalance  positions.  The rate used in calculating the accrued liability is the
average of the annual  production  costs per Mcf. At December 31, 2000 and 1999,
cumulative  total  gas  sales  volumes  for  overproduced   wells  exceeded  the
Partnerships'  pro-rata  share of total gas  production  from these wells by the
following amounts:

                                2000                       1999

      -----------       -------       --------     -------     --------

          I-D            78,379       $ 41,157      71,772     $ 26,398
          I-E           365,979        243,815     326,006      189,964
          I-F           151,210        185,520     128,688      122,086


      Oil and Gas Sales and Gas Imbalance Payable

      The Partnerships' oil and condensate production is sold, title passed, and
revenue recognized at or near the Partnerships'  wells under short-term purchase
contracts  at  prevailing  prices  in  accordance  with  arrangements  which are
customary in the oil  industry.  Sales of gas  applicable  to the  Partnerships'
interest in producing oil and gas leases are recorded as revenue when the gas is
metered and title transferred  pursuant to the gas sales contracts  covering the
Partnerships'  interest in gas  reserves.  During such times as a  Partnership's
sales of gas exceed its pro rata ownership in a well, such sales are recorded as
revenue unless total sales from the well have exceeded the  Partnership's  share
of estimated  total gas reserves  underlying  the  property,  at which time such
excess is  recorded as a  liability.  The rates per Mcf used to  calculate  this
liability  are based on the average gas prices  received  for the volumes at the
time the overproduction occurred. This also approximates the price for which the
Partnerships  are currently  settling this  liability.  At December 31, 2000 and
1999  total  sales  exceeded  the  Partnerships'  share of  estimated  total gas
reserves as follows:

These  amounts were recorded as gas  imbalance  payables in accordance  with the
sales  method.  These gas  imbalance  payables  will be  settled  by either  gas
production by the  underproduced  party in excess of current  estimates of total
gas  reserves  for the well or by a  negotiated  or  contractual  payment to the
underproduced party.


      General and Administrative Overhead

      The General  Partner and its  affiliates are reimbursed for actual general
and  administrative  costs  incurred  and  attributable  to the  conduct  of the
business affairs and operations of the Partnerships.


      Use of Estimates in Financial Statements

      The  preparation  of financial  statements  in conformity  with  generally
accepted  accounting  principles  requires  management  to  make  estimates  and
assumptions  that  affect the  reported  amounts of assets and  liabilities  and
disclosure of  contingent  assets and  liabilities  at the date of the financial
statements  and the  reported  amounts  of  revenues  and  expenses  during  the
reporting period. Actual results could differ from those estimates. Further, the
deferred  charge,  the gas  imbalance  payable,  and the accrued  liability  all
involve  estimates  which  could  materially  differ  from  the  actual  amounts
ultimately realized or incurred in the near term. Oil and gas reserves (see Note
4) also involve  significant  estimates which could  materially  differ from the
actual amounts ultimately realized.


      Income Taxes

      Income or loss for income tax  purposes  is  includable  in the income tax
returns of the partners.  Accordingly,  no recognition  has been given to income
taxes in these financial statements.


2.    TRANSACTIONS WITH RELATED PARTIES

      The  Partnerships  reimburse  the  General  Partner  for the general and
administrative overhead applicable to the



                                     -F25-
<PAGE>



Partnerships,  based on an  allocation  of actual costs  incurred by the General
Partner.  When actual costs incurred benefit other  Partnerships and affiliates,
the  allocation  of  costs is based  on the  relationship  of the  Partnerships'
reserves to the total reserves owned by all  Partnerships  and  affiliates.  The
General  Partner  believes this  allocation  method is reasonable.  Although the
actual costs incurred by the General  Partner and its affiliates have fluctuated
during the three years presented,  the amounts charged to the Partnerships  have
not fluctuated every year due to expense  limitations imposed by the Partnership
Agreements.  The following is a summary of payments made to the General  Partner
or its affiliates by the  Partnerships for general and  administrative  overhead
costs for the years ended December 31, 2000, 1999, and 1998:

            Partnership         2000         1999         1998
            -----------       --------     --------     --------

                I-F            159,120      159,120      159,120


      Affiliates  of the  Partnerships  operate  certain  of  the  Partnerships'
properties  and  their  policy  is to bill the  Partnerships  for all  customary
charges and cost reimbursements associated with these activities,  together with
any compressor rentals, consulting, or other services provided. Such charges are
comparable  to third  party  charges in the area where the wells are located and
are the same as charged to other working interest owners in the wells.


3.    MAJOR CUSTOMERS

      The following table sets forth purchasers who  individually  accounted for
ten  percent or more of each  Partnership's  combined  oil and gas sales for the
years ended December 31, 2000, 1999, and 1998:

      In the  event  of  interruption  of  purchases  by one or  more  of  these
significant  customers or the cessation or material  change in  availability  of
open-access  transportation  by the  Partnerships'  pipeline  transporters,  the
Partnerships may encounter  difficulty in marketing their gas and in maintaining
historic sales levels. Alternative purchasers or transporters may not be readily
available.


4.    SUPPLEMENTAL OIL AND GAS INFORMATION

      The  following   supplemental   information  regarding  the  oil  and  gas

      Quantities of Proved Oil and Gas Reserves - Unaudited

      The  following  tables   summarize   changes  in  net  quantities  of  the
Partnerships'  proved  reserves,  all of which are located in the United States,
for the periods  indicated.  The proved reserves at December 31, 2000, 1999, and
1998,  were  estimated  by petroleum  engineers  employed by  affiliates  of the
Partnerships.  Certain reserve  information was reviewed by Ryder Scott Company,
L.P., an  independent  petroleum  engineering  firm.  The following  information
includes certain gas balancing  adjustments which cause the gas volume to differ
from the reserve  reports  prepared by the General Partner and reviewed by Ryder
Scott.

The process of estimating oil and gas reserves is complex, requiring significant
subjective decisions in the evaluation of available geological, engineering, and
economic data for each reservoir. The data for a given reservoir may change



                                     -F32-
<PAGE>



substantially  over  time  as  a  result  of,  among  other  things,  additional
development  activity,  production  history,  and viability of production  under
varying  economic  conditions;  consequently,  it is  reasonably  possible  that
material  revisions to existing reserve  estimates may occur in the near future.
Although  every  reasonable  effort  has been  made to ensure  that the  reserve
