1.     ACCOUNTING POLICIES
      -------------------

      The combined balance sheets as of September 30, 1998,  combined statements
      of operations  for the three and nine months ended  September 30, 1998 and
      1997,  and  combined  statements  of cash flows for the nine months  ended
      September 30, 1998 and 1997 have been prepared by Geodyne Resources, Inc.,
      the  General  Partner of the limited  partnerships,  without  audit.  Each
      limited  partnership  is a general  partner in the related  Geodyne Energy
      Income Production  Partnership in which Geodyne Resources,  Inc. serves as
      the  managing  partner.  Unless  the  context  indicates  otherwise,   all
      references to a "Partnership" or the  "Partnerships" are references to the
      limited partnership and its related production partnership,  collectively,
      and all references to the "General  Partner" are references to the general
      partner  of the  limited  partnerships  and the  managing  partner  of the
      production  partnerships,  collectively.  In the opinion of management the
      financial statements referred to above include all necessary  adjustments,
      consisting of normal recurring adjustments, to present fairly the combined
      financial  position  at  September  30,  1998,  the  combined  results  of
      operations  for the three and nine  months  ended  September  30, 1998 and
      1997, and the combined cash flows for the nine months ended  September 30,
      1998 and 1997.

      Information  and  footnote  disclosures  normally  included  in  financial
      statements  prepared in  accordance  with  generally  accepted  accounting
      principles  have been  condensed  or  omitted.  The  accompanying  interim
      financial  statements should be read in conjunction with the Partnerships'
      Annual Report on Form 10-K filed for the year ended December 31, 1997. The
      results of  operations  for the period  ended  September  30, 1998 are not
      necessarily indicative of the results to be expected for the full year.

      The  Limited  Partners'  net  income  or loss per unit is based  upon each
      $1,000 initial capital contribution.

      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 prior to their transfer to the Partnerships.  Leasehold impairment
      is recognized based upon an individual property assessment and exploratory
      experience.  Upon discovery of commercial  reserves,  leasehold  costs are
      transferred to producing properties.

      Depletion of the costs 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  unit-of-production
      method.  The  Partnerships'  depletion,   depreciation,  and  amortization
      includes  estimated  dismantlement and abandonment costs, net of estimated
      salvage value.

      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  difference  between  asset cost and
      salvage value is charged to accumulated depreciation.

      Statement of Financial  Accounting Standards ("SFAS") No. 121, "Accounting
      for the  Impairment  of Long Lived  Assets and Assets Held for  Disposal",
      requires successful efforts companies, like the Partnerships,  to evaluate
      the  recoverability  of the  carrying  costs of their  proved  oil and gas
      properties at the lowest level for which there are identifiable cash flows
      that are largely  independent of the cash flows of other groups of oil and
      gas properties.  With respect to the Partnerships' oil and gas properties,
      this evaluation was performed for each field.  SFAS No. 121, provides that
      if the  unamortized  costs of oil and gas properties for each 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.   The
      Partnerships  recorded  a non-cash  charge  against  earnings  (impairment
      provision)  during the nine months ended  September  30, 1997  pursuant to
      SFAS No. 121 as follows:

      No such charge was recorded in the nine months ended  September  30, 1998.
      The risk that the Partnerships  will be required to record such impairment
      provisions in the future increases when oil and gas prices are depressed.

2.     TRANSACTIONS WITH RELATED PARTIES
      ---------------------------------

      The Partnerships'  partnership agreements provide for reimbursement to the
      General Partner for all direct general and administrative expenses and for
      the general and  administrative  overhead  applicable to the  Partnerships
      based on an allocation of actual costs  incurred.  During the three months
      ended  September 30, 1998 the following  payments were made to the General
      Partner or its affiliates by the Partnerships:

ITEM 2.     MANAGEMENT'S  DISCUSSION  AND ANALYSIS OF FINANCIAL  CONDITION AND
            RESULTS OF OPERATIONS

USE OF FORWARD-LOOKING STATEMENTS AND ESTIMATES
- -----------------------------------------------

      This Quarterly 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
      Quarterly 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, and otherwise indicated.

GENERAL
- -------

      The  Partnerships  are engaged in the business of acquiring  and operating
      producing oil and gas properties located in the continental United States.
      In general, a Partnership acquired producing properties and did not engage
      in  development  drilling  or  enhanced  recovery  projects,  except as an
      incidental  part of the management of the producing  properties  acquired.
      Therefore,  the  economic  life  of  each  Partnership,  and  its  related
      Production Partnership, is limited to the period of time required to fully
      produce its acquired oil and gas  reserves.  The net proceeds from the oil
      and gas operations are distributed to the Limited Partners and the General
      Partner  in  accordance  with the terms of the  Partnerships'  partnership
      agreements.

LIQUIDITY AND CAPITAL RESOURCES
- -------------------------------

      The Partnerships began operations and investors were assigned their rights
      as Limited Partners,  having made capital contributions in the amounts and
      on the dates set forth below:

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

                 I-B          July 12, 1985               $11,957,700
                 I-C          December 20, 1985             8,884,900
                 I-D          March 4, 1986                 7,194,700
                 I-E          September 10, 1986           41,839,400
                 I-F          December 16, 1986            14,320,900

      In general,  the amount of funds  available for  acquisition  of producing
      properties was equal to the capital contributions of the Limited Partners,
      less 15% for sales  commissions and  organization and management fees. All
      of the Partnerships have fully invested their capital contributions.

      Net proceeds from the  operations  less  necessary  operating  capital are
      distributed to the Limited Partners on a quarterly basis. Revenues and net
      proceeds of a Partnership  are largely  dependent  upon the volumes of oil
      and gas sold and the  prices  received  for  such oil and gas.  While  the
      General  Partner cannot predict  future  pricing  trends,  it believes the
      working  capital  available as of  September  30, 1998 and the net revenue
      generated from future operations will provide  sufficient  working capital
      to meet current and future obligations.

      The I-C, I-D, I-E and I-F  Partnerships'  Statements of Cash Flows for the
      nine months ended September 30, 1998 include proceeds from the sale of oil
      and gas properties. The proceeds received during the first quarter of 1998
      were  included in the  Partnerships'  cash  distributions  paid during May
      1998,  the  proceeds  received  during  the  second  quarter  of 1998 were
      included in the Partnerships'  cash distributions paid during August 1998,
      and the  proceeds  received  during  the  third  quarter  of 1998  will be
      included in the  Partnerships'  cash  distributions to be paid in November
      1998. It is possible that the  Partnerships'  repurchase values and future
      cash  distributions  could decline as a result of the disposition of these
      properties.  On the other hand, the General Partner believes there will be
      beneficial operating  efficiencies related to the Partnerships'  remaining
      properties.  This is primarily  due to the fact that the  properties  sold
      generally bore a higher ratio of



                                       27
<PAGE>



      operating  expenses  as  compared  to  reserves  than the  Partnerships'
      remaining properties.

      The  Partnerships  will terminate on December 31, 1999 in accordance  with
      their partnership agreements.  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. As of the date of this  Quarterly  Report,
      the General  Partner has not determined  whether to extend the term of any
      Partnership.


RESULTS OF OPERATIONS
- ---------------------

      GENERAL DISCUSSION

      The following  general  discussion  should be read in conjunction with the
      analysis  of results of  operations  provided  below.  The most  important
      variable  affecting the Partnerships'  revenues is the prices received for
      the sale of oil and  gas.  Predicting  future  prices  is very  difficult.
      Substantially  all of the Partnerships' gas reserves are being sold in 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. Such spot market sales are generally short-term in nature and
      are dependent upon the obtaining of  transportation  services  provided by
      pipelines. In addition, crude oil prices are at or near their lowest level
      in the past  decade  due  primarily  to the  global  surplus of crude oil.
      Management is unable to predict whether future oil and gas prices will (i)
      stabilize, (ii) increase, or (iii) decrease.

      As shown in the table  above,  total oil and gas sales  increased  $34,414
      (76.0%),  for the three months ended September 30, 1998 as compared to the
      three months ended



                                       28
<PAGE>



      September 30, 1997. Of this increase, approximately $56,000 was related to
      an increase  in the  volumes of gas sold,  which  increase  was  partially
      offset by decreases of  approximately  $5,000 related to a decrease in the
      volumes of oil sold and approximately $15,000 related to a decrease in the
      average price of gas sold. Volumes of oil sold decreased 256 barrels while
      volumes of gas sold  increased  26,203  Mcf,  for the three  months  ended
      September  30, 1998 as compared to the three  months ended  September  30,
      1997. The decrease in volumes of oil sold resulted primarily from the sale
      of three  significant  wells in 1997.  The increase in volumes of gas sold
      resulted  primarily from positive prior period volume  adjustments made by
      the purchasers on three wells during the three months ended  September 30,
      1998.  Average oil and gas prices decreased to $13.05 per barrel and $1.77
      per Mcf, respectively,  for the three months ended September 30, 1998 from
      $18.51 per barrel and $2.13 per Mcf,  respectively,  for the three  months
      ended September 30, 1997.

      Oil and gas production  expenses  (including lease operating  expenses and
      production  taxes)  decreased  $6,602  (22.8%) for the three  months ended
      September  30, 1998 as compared to the three  months ended  September  30,
      1997. This decrease resulted  primarily from workover expenses incurred on
      two significant  wells during the three months ended September 30, 1997 in
      order to improve the recovery of reserves.  As a percentage of oil and gas
      sales,  these  expenses  decreased  to 28.0%  for the three  months  ended
      September  30, 1998 from 63.9% for the three  months ended  September  30,
      1997.  This  percentage  decrease was primarily due to the positive  prior
      period volume adjustments.

      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
      increased $9,623 (128.9%) for the three months ended September 30, 1998 as
      compared to the three  months ended  September  30,  1997.  This  increase
      resulted  primarily  from the  increase  in volumes of gas sold during the
      three  months  ended  September  30, 1998 as compared to the three  months
      ended  September  30 1997.  As a  percentage  of oil and gas  sales,  this
      expense  increased to 21.4% for the three months ended  September 30, 1998
      from 16.5% for the three months ended  September 30, 1997. This percentage
      increase was primarily  due to the decreases in the average  prices of oil
      and gas sold during the three months ended  September 30, 1998 as compared
      to the three months ended September 30 1997.

      General and  administrative  expenses  increased $585 (4.3%) for the three
      months  ended  September  30, 1998 as compared to the three  months  ended
      September 30, 1997. As a percentage of oil and gas sales,  these  expenses
      decreased  to 17.6% for the three  months  ended  September  30, 1998 from
      29.7% for the three  months ended  September  30,  1997.  This  percentage
      decrease was primarily due to the increase in oil and gas sales.

      As shown in the table  above,  total oil and gas sales  decreased  $36,924
      (15.6%) for the nine months  ended  September  30, 1998 as compared to the
      nine months ended  September  30, 1997.  Of this  decrease,  approximately
      $6,000 and $43,000, respectively, were related to decreases in the average
      prices of oil and gas sold and  approximately  $12,000  was  related  to a
      decrease in the volumes of oil sold, which decreases were partially offset
      by an  increase  of  approximately  $25,000  related to an increase in the
      volumes  of gas sold.  Volumes of oil sold  decreased  633  barrels  while
      volumes  of gas  sold  increased  10,394  Mcf for the  nine  months  ended
      September  30, 1998 as compared to the nine  months  ended  September  30,
      1997.  The decrease in volumes of oil sold resulted  primarily  from (i) a
      normal decline in production on several wells due to diminishing  reserves
      and (ii) the sale of three  significant  wells in 1997.  The  increase  in
      volumes of gas sold resulted  primarily  from positive prior period volume
      adjustments made by the purchasers on three  significant  wells during the
      nine months ended September 30, 1998. Average oil and gas prices decreased
      to $13.14 per barrel and $1.95 per Mcf, respectively,  for the nine months
      ended  September  30,  1998  from  $19.54  per  barrel  and $2.40 per Mcf,
      respectively, for the nine months ended September 30, 1997.

      Oil and gas production  expenses  (including lease operating  expenses and
      production  taxes)  decreased  $32,052  (35.5%) for the nine months  ended
      September  30, 1998 as compared to the nine  months  ended  September  30,
      1997. This decrease resulted  primarily from workover expenses incurred on
      two  significant  wells during the nine months ended September 30, 1997 in
      order to improve the recovery of reserves.  As a percentage of oil and gas
      sales,  these  expenses  decreased  to  29.1%  for the nine  months  ended
      September  30, 1998 from 38.1% for the nine  months  ended  September  30,
      1997. This percentage decrease was primarily due to the dollar decrease in
      production expenses.

      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
      increased  $3,324  (9.3%) for the nine months ended  September 30, 1998 as
      compared  to the nine months  ended  September  30,  1997.  This  increase
      resulted  primarily  from the  increase  in volumes of gas sold during the
      nine months ended  September 30, 1998 as compared to the nine months ended
      September  30 1997.  As a  percentage  of oil and gas sales,  this expense
      increased to 19.5% for the nine months ended September 30, 1998 from 15.1%
      for the nine months ended September 30, 1997. This percentage increase was
      primarily due to the  decreases in the average  prices of oil and gas sold
      during the nine months  ended  September  30, 1998 as compared to the nine
      months ended September 30 1997.

      The I-B  Partnership  recognized  a non-cash  charge  against  earnings of
      $19,726  during the nine months ended  September 30, 1997. Of this amount,
      $17,233 was related to the decline in oil and gas prices used to determine
      the  recoverability  of proved oil and gas  reserves at March 31, 1997 and
      $2,493 was  related  to the  writing  off of  unproved  properties.  These
      unproved  properties  were  written  off  based on the  General  Partner's
      determination that it was unlikely that such properties would be developed
      due to the low oil and gas prices  received  over the prior  several years
      and provisions in the I-B Partnership's  Partnership Agreement which limit
      the  level  of  permissible  drilling  activity.  No  similar  charge  was
      necessary during the nine months ended September 30, 1998.

      General and  administrative  expenses decreased $1,825 (3.7%) for the nine
      months  ended  September  30, 1998 as  compared  to the nine months  ended
      September 30, 1997. As a percentage of oil and gas sales,  these  expenses
      increased to 24.0% for the nine months ended September 30, 1998 from 21.0%
      for the nine months ended September 30, 1997. This percentage increase was
      primarily due to the decrease in oil and gas sales.

      The Limited Partners have received cash  distributions  through  September
      30,  1998  totaling  $6,678,527  or 55.85% of  Limited  Partners'  capital
      contributions.

      Oil and gas sales                           $95,155          $203,427
      Oil and gas production expenses             $52,940          $ 97,752
      Barrels produced                              3,483             5,660
      Mcf produced                                 26,940            38,365
      Average price/Bbl                           $ 12.19          $  17.12
      Average price/Mcf                           $  1.96          $   2.78

      As shown in the table above,  total oil and gas sales  decreased  $108,272
      (53.2%) for the three months ended  September  30, 1998 as compared to the
      three months ended  September  30, 1997. Of this  decrease,  approximately
      $37,000  and  $32,000,  respectively,  were  related to  decreases  in the
      volumes  of oil  and gas  sold  and  approximately  $17,000  and  $22,000,
      respectively,  were related to decreases in the average  prices of oil and
      gas sold.  Volumes of oil and gas sold decreased  2,177 barrels and 11,425
      Mcf,  respectively,  for the three  months  ended  September  30,  1998 as
      compared to the three months  ended  September  30, 1997.  The decrease in
      volumes  of oil sold  resulted  primarily  from  (i)  normal  declines  in
      production due to diminishing  reserves on two significant  wells and (ii)
      the sale of one  significant  well in 1997. The decrease in volumes of gas
      sold  resulted  primarily  from  normal  declines  in  production  due  to
      diminishing  reserves on two significant wells. Average oil and gas prices
      decreased  to $12.19 per barrel and $1.96 per Mcf,  respectively,  for the
      three months ended September 30, 1998 from $17.12 per barrel and $2.78 per
      Mcf, respectively, for the three months ended September 30, 1997.

      Oil and gas production  expenses  (including lease operating  expenses and
      production  taxes)  decreased  $44,812  (45.8%) for the three months ended
      September  30, 1998 as compared to the three  months ended  September  30,
      1997.  This  decrease  resulted  primarily  from (i) the  decreases in the
      volumes of oil and gas sold during the three  months ended  September  30,
      1998 as  compared to the three  months  ended  September  30,  1997,  (ii)
      workover  expenses  incurred on one  significant  well in 1997 in order to
      improve the  recovery of reserves,  and (iii) the sale of one  significant
      well  in  1997.  As a  percentage  of oil and gas  sales,  these  expenses
      increased  to 55.6% for the three  months  ended  September  30, 1998 from
      48.1% for the three  months ended  September  30,  1997.  This  percentage
      increase was primarily  due to the decreases in the average  prices of oil
      and gas sold during the three

      months  ended  September  30, 1998 as compared to the three  months  ended
      September 30, 1997.

      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
      decreased  $4,042 (43.1%) for the three months ended September 30, 1998 as
      compared to the three  months ended  September  30,  1997.  This  decrease
      resulted  primarily  from the  decreases  in  volumes  of oil and gas sold
      during the three months ended  September 30, 1998 as compared to the three
      months ended  September  30, 1997.  As a percentage  of oil and gas sales,
      this expense  increased to 5.6% for the three months ended  September  30,
      1998 from 4.6% for the three months ended September 30, 1997.

      General and  administrative  expenses  increased $433 (1.7%) for the three
      months  ended  September  30, 1998 as compared to the three  months  ended
      September 30, 1997. As a percentage of oil and gas sales,  these  expenses
      increased  to 26.7% for the three  months  ended  September  30, 1998 from
      12.3% for the three  months ended  September  30,  1997.  This  percentage
      increase was primarily due to the decrease in oil and gas sales.

      Average price/Mcf                           $   2.45         $   2.77

      As shown in the table above,  total oil and gas sales  decreased  $298,152
      (44.1%) for the nine months  ended  September  30, 1998 as compared to the
      nine months ended  September  30, 1997.  Of this  decrease,  approximately
      $114,000  and  $80,000,  respectively,  were  related to  decreases in the
      volumes  of oil  and gas  sold  and  approximately  $72,000  and  $32,000,
      respectively,  were related to decreases in the average  prices of oil and
      gas sold.  Volumes of oil and gas sold decreased  6,017 barrels and 28,987
      Mcf,  respectively,  for the  nine  months  ended  September  30,  1998 as
      compared to the nine months  ended  September  30,  1997.  The decrease in
      volumes  of  oil  sold  resulted  primarily  from  (i)  the  sale  of  one
      significant  well in 1997 and (ii) normal  declines in  production  due to
      diminishing  reserves on another significant well. The decrease in volumes
      of gas sold resulted  primarily from normal  declines in production due to
      diminishing reserves on

      a  significant  well.  Average oil and gas prices  decreased to $12.37 per
      barrel  and  $2.45  per  Mcf,  respectively,  for the  nine  months  ended
      September 30, 1998 from $18.99 per barrel and $2.77 per Mcf, respectively,
      for the nine months ended September 30, 1997.

      Oil and gas production  expenses  (including lease operating  expenses and
      production  taxes)  decreased  $84,921  (34.1%) for the nine months  ended
      September  30, 1998 as compared to the nine  months  ended  September  30,
      1997.  This  decrease  resulted  primarily  from (i) the  decreases in the
      volumes of oil and gas sold during the nine  months  ended  September  30,
      1998 as  compared  to the nine  months  ended  September  30,  1997,  (ii)
      workover  expenses  incurred on one  significant  well in 1997 in order to
      improve the recovery of reserves and (iii) the sale of another significant
      well  in  1997.  As a  percentage  of oil and gas  sales,  these  expenses
      increased to 43.5% for the nine months ended September 30, 1998 from 36.8%
      for the nine months ended September 30, 1997. This percentage increase was
      primarily due to the  decreases in the average  prices of oil and gas sold
      during the nine months  ended  September  30, 1998 as compared to the nine
      months ended September 30, 1997.

      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
      decreased  $14,332 (43.9%) for the nine months ended September 30, 1998 as
      compared  to the nine months  ended  September  30,  1997.  This  decrease
      resulted  primarily  from the  decreases  in  volumes  of oil and gas sold
      during the nine months  ended  September  30, 1998 as compared to the nine
      months ended  September  30, 1997.  As a percentage  of oil and gas sales,
      this  expense  remained  relatively  constant  at 4.9% for the nine months
      ended  September 30, 1998 and 4.8% for the nine months ended September 30,
      1997.

      The I-C  Partnership  recognized  a non-cash  charge  against  earnings of
      $4,679 during the nine months ended  September 30, 1997 primarily  related
      to the decline in oil and gas prices used to determine the  recoverability
      of proved oil and gas  reserves at March 31, 1997.  No similar  charge was
      necessary during the nine months ended September 30, 1998.

      General and  administrative  expenses decreased $1,473 (1.8%) for the nine
      months  ended  September  30, 1998 as  compared  to the nine months  ended
      September 30, 1997. As a percentage of oil and gas sales,  these  expenses
      increased to 21.4% for the nine months ended September 30, 1998 from 12.1%
      for the nine months ended September 30, 1997. This percentage increase was
      primarily due to the decrease in oil and gas sales.

      Average price/Mcf                           $   1.94         $   2.44

      As shown in the table  above,  total oil and gas sales  increased  $18,614
      (6.0%) for the three  months ended  September  30, 1998 as compared to the
      three months ended  September  30, 1997. Of this  increase,  approximately
      $130,000  was related to an  increase  in the  volumes of gas sold,  which
      increase  was  partially  offset by  decreases  of  approximately  $22,000
      related to a decrease in the volumes of oil sold and approximately $12,000
      and $78,000,  respectively,  related to decreases in the average prices of
      oil and gas  sold.  Volumes  of oil sold  decreased  1,306  barrels  while
      volumes  of gas sold  increased  53,374  Mcf for the  three  months  ended
      September  30, 1998 as compared to the three  months ended  September  30,
      1997.  The decrease in volumes of oil sold resulted  primarily from normal
      declines in  production  due to  diminishing  reserves on one  significant
      well. The increase in volumes of gas sold resulted primarily from positive
      prior  period  volume   adjustments   made  by  the  purchasers  on  three
      significant  wells  during the three  months  ended  September  30,  1998.
      Average  oil and gas prices  decreased  to $12.20 per barrel and $1.94 per
      Mcf,  respectively,  for the three  months ended  September  30, 1998 from
      $16.85 per barrel and $2.44 per Mcf,  respectively,  for the three  months
      ended September 30, 1997.

      Oil and gas production  expenses  (including lease operating  expenses and
      production  taxes)  decreased  $42,487  (47.5%) for the three months ended
      September  30, 1998 as compared to the three  months ended  September  30,
      1997. This decrease resulted  primarily from workover expenses incurred on
      two significant  wells during the three months ended September 30, 1997 in
      order to improve the recovery of reserves.  As a percentage of oil and gas
      sales,  these  expenses  decreased  to 14.2%  for the three  months  ended
      September 30, 1998 from



                                       35

      28.6% for the  three  months  ended  September  30,  1997.  This  decrease
      resulted primarily from the dollar decrease in production expenses.

      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
      decreased  $1,685 (7.5%) for the three months ended  September 30, 1998 as
      compared to the three months ended  September 30, 1997. As a percentage of
      oil and gas sales,  this  expense  decreased  to 6.3% for the three months
      ended  September  30, 1998 from 7.2% for the three months ended  September
      30, 1997.

      General and  administrative  expenses  increased $379 (1.8%) for the three
      months  ended  September  30, 1998 as compared to the three  months  ended

      As shown in the table above,  total oil and gas sales  decreased  $306,118
      (27.4%) for the nine months  ended  September  30, 1998 as compared to the
      nine months ended  September  30, 1997.  Of this  decrease,  approximately
      $68,000  and  $39,000,  respectively,  were  related to  decreases  in the
      volumes  of oil and gas  sold  and  approximately  $58,000  and  $141,000,
      respectively,  were related to decreases in the average  prices of oil and
      gas sold.  Volumes of oil and gas sold decreased  3,492 barrels and 15,924
      Mcf,  respectively,  for the  nine  months  ended  September  30,  1998 as
      compared to the nine months  ended  September  30,  1997.  The decrease in
      volumes of oil sold resulted primarily from a normal decline in production
      due to diminishing  reserves on one significant well.  Average oil and gas
      prices decreased to $12.94 per barrel and $2.03 per Mcf, respectively, for
      the nine months ended  September 30, 1998 from $19.48 per barrel and $2.44
      per Mcf, respectively, for the nine months ended September 30, 1997.

      As discussed in Liquidity and Capital Resources above, the I-D Partnership
      sold certain oil and gas properties during the nine months ended September
      30,  1998 and  recognized  a $259,982  gain on such sales.  Similar  sales
      during the nine  months  ended  September  30,  1997  resulted  in the I-D
      Partnership recognizing similar gains totaling $15,961.

      Oil and gas production  expenses  (including lease operating  expenses and
      production  taxes)  decreased  $81,240  (37.4%) for the nine months  ended
      September  30, 1998 as compared to the nine  months  ended  September  30,
      1997. This decrease  resulted  primarily from (i) a decrease in production
      taxes  associated with the decrease in oil and gas sales and (ii) workover
      expenses  incurred on two  significant  wells during the nine months ended
      September  30, 1997 in order to improve the  recovery  of  reserves.  As a
      percentage of oil and gas sales, these expenses decreased to 16.8% for the
      nine months ended  September 30, 1998 from 19.5% for the nine months ended
      September  30, 1997.  This  percentage  decrease was  primarily due to the
      dollar decrease in production expenses.

      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
      decreased  $34,384 (41.6%) for the nine months ended September 30, 1998 as
      compared  to the nine months  ended  September  30,  1997.  This  decrease
      resulted  primarily  from (i) the decreases in volumes of oil and gas sold
      during the nine months  ended  September  30, 1998 as compared to the nine
      months ended September 30, 1997 and (ii) upward revisions in the estimates
      of remaining oil and gas reserves at December 31, 1997. As a percentage of
      oil and gas sales,  this  expense  decreased  to 6.0% for the nine  months
      ended September 30, 1998 from 7.4% for the nine months ended September 30,
      1997.

      The I-D  Partnership  recognized  a non-cash  charge  against  earnings of
      $61,790  during the nine months ended  September 30, 1997. Of this amount,
      $12,290 was related to the decline in oil and gas prices used to determine
      the  recoverability  of proved oil and gas  reserves at March 31, 1997 and
      $49,500  was related to the  writing  off of  unproved  properties.  These
      unproved  properties  were  written  off  based on the  General  Partner's
      determination that it was unlikely that such properties would be developed
      due to the low oil and gas prices  received  over the prior  several years
      and provisions in the I-D Partnership's  Partnership Agreement which limit
      the  level  of  permissible  drilling  activity.  No  similar  charge  was
      necessary during the nine months ended September 30, 1998.

      General and  administrative  expenses decreased $1,421 (2.0%) for the nine
      months  ended  September  30, 1998 as  compared  to the nine months  ended
      September 30, 1997. As a percentage of oil and gas sales,  these  expenses
      increased to 8.5% for the nine months ended  September  30, 1998 from 6.3%
      for the nine months ended September 30, 1997. This percentage increase was
      primarily due to the decrease in oil and gas sales.

      The Limited Partners have received cash  distributions  through  September
      30, 1998  totaling  $13,753,175  or 191.16% of Limited  Partners'  capital

      As shown in the table  above,  total oil and gas sales  increased  $38,529
      (3.0%) for the three  months ended  September  30, 1998 as compared to the
      three months ended  September  30, 1997. Of this  increase,  approximately
      $266,000  was related to an  increase  in the  volumes of gas sold,  which
      increase  was  partially  offset by  decreases  of  approximately  $68,000
      related to a decrease in the volumes of oil sold and $95,000 and  $64,000,
      respectively,  related to decreases  in the average  prices of oil and gas
      sold.  Volumes of oil sold  decreased  4,039  barrels while volumes of gas
      sold increased  133,902 Mcf for the three months ended  September 30, 1998
      as compared to the three months ended  September 30, 1997. The decrease in
      volumes  of oil sold  resulted  primarily  from (i) a  normal  decline  in
      production on several significant wells and (ii) the sale of several wells
      in 1997.  The  increase  in volumes of gas sold  resulted  primarily  from
      positive  prior period  volume  adjustments  made by  purchasers  on three
      significant  wells  during the three  months  ended  September  30,  1998.
      Average  oil and gas prices  decreased  to $10.56 per barrel and $1.88 per
      Mcf,  respectively,  for the three  months ended  September  30, 1998 from
      $16.83 per barrel and $1.98 per Mcf,  respectively,  for the three  months
      ended September 30, 1997.

      Oil and gas production  expenses  (including lease operating  expenses and
      production  taxes)  decreased  $114,401 (27.2%) for the three months ended
      September  30, 1998 as compared to the three  months ended  September  30,
      1997. This decrease resulted  primarily from workover expenses incurred on
      three  significant  wells during the three months ended September 30, 1997
      in order to improve the recovery of reserves.  As a percentage  of oil and
      gas sales,  these  expenses  decreased to 23.0% for the three months ended
      September  30, 1998 from 32.5% for the three  months ended  September  30,
      1997. This percentage decrease was primarily due to the dollar decrease in
      production expenses.

      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
      increased $19,258 (10.1%) for the three months ended September 30, 1998 as
      compared to the three  months ended  September  30,  1997.  This  increase
      resulted  primarily  from the  increase  in volumes of gas sold during the
      three  months  ended  September  30, 1998 as compared to the three  months
      ended  September  30,  1997.  As a percentage  of oil and gas sales,  this
      expense  increased to 15.8% for the three months ended  September 30, 1998
      from 14.8% for the three months ended September 30, 1997.

      General and administrative  expenses increased $1,913 (1.5%) for the three

      (24.0%) for the nine months  ended  September  30, 1998 as compared to the
      nine months ended  September  30, 1997.  Of this  decrease,  approximately
      $180,000 and $81,000,  respectively,  were related to decreases in volumes
      of oil and gas sold and approximately $344,000 and $476,000, respectively,
      were  related  to  decreases  in the  average  prices of oil and gas sold.
      Volumes of oil and gas sold decreased 9,288 barrels and

      36,386 Mcf, respectively,  for the nine months ended September 30, 1998 as
      compared to the nine months  ended  September  30,  1997.  The decrease in
      volumes of oil sold resulted  primarily from (i) the sale of several wells
      in 1997 and (ii) normal declines in production due to diminishing reserves
      on several wells.  The decrease in volumes of gas sold resulted  primarily
      from normal  declines in  production  due to  diminishing  reserves on one
      significant  well.  Average  oil and gas  prices  decreased  to $12.35 per
      barrel  and  $1.90  per  Mcf,  respectively,  for the  nine  months  ended
      September 30, 1998 from $19.38 per barrel and $2.23 per Mcf, respectively,
      for the nine months ended September 30, 1997.

      As discussed in Liquidity and Capital Resources above, the I-E Partnership
      sold certain oil and gas properties during the nine months ended September
      30, 1998 and  recognized a $1,159,004  gain on such sales.  Similar  sales
      during the nine  months  ended  September  30,  1997  resulted  in the I-E
      Partnership recognizing similar gains totaling $62,609.

      Oil and gas production  expenses  (including lease operating  expenses and
      production  taxes)  decreased  $324,954  (26.4%) for the nine months ended
      September  30, 1998 as compared to the nine  months  ended  September  30,
      1997. This decrease  resulted  primarily from (i) a decrease in production
      taxes  associated with the decrease in oil and gas sales and (ii) workover
      expenses  incurred on several wells during the nine months ended September
      30, 1997 in order to improve the recovery of reserves.  As a percentage of
      oil and gas sales,  these expenses remained  relatively  constant at 26.5%
      for the nine months ended September 30, 1998 and 27.4% for the nine months
      ended September 30, 1997.

      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
      decreased  $67,607 (11.4%) for the nine months ended September 30, 1998 as
      compared  to the nine months  ended  September  30,  1997.  This  decrease
      resulted  primarily  from (i) the decreases in volumes of oil and gas sold
      during the nine months  ended  September  30, 1998 as compared to the nine
      months ended September 30, 1997 and (ii) upward revisions in the estimates
      of remaining gas reserves at December 31, 1997. As a percentage of oil and
      gas sales,  this  expense  increased  to 15.3% for the nine  months  ended
      September  30, 1998 from 13.1% for the nine  months  ended  September  30,
      1997. This  percentage  increase was primarily due to the decreases in the
      average prices of oil and gas sold during the nine months ended  September
      30, 1998 as compared to the nine months ended September 30, 1997.

      The I-E  Partnership  recognized  a non-cash  charge  against  earnings of
      $291,690  during the nine months ended September 30, 1997. Of this amount,
      $59,728 was related to the decline in oil and gas prices used to determine
      the  recoverability  of proved oil and gas  reserves at March 31, 1997 and
      $231,962  was related to the writing  off of  unproved  properties.  These

      from (i) the sale of  several  wells  during  1997 and 1998,  (ii)  normal
      declines in production  due to  diminishing  reserves on several wells and
      (iii) the shutting in of two significant wells for repairs and maintenance
      during the three months ended  September 30, 1998. The increase in volumes
      of  gas  sold  resulted   primarily  from  positive  prior  period  volume
      adjustments  made by purchasers on two significant  wells during the three

      September  30, 1998 as compared to the three  months ended  September  30,
      1997. This decrease resulted primarily from (i) workover expenses incurred
      on two  significant  wells in 1997 in order to  improve  the  recovery  of
      reserves  and  (ii  the  sale  of  one  significant well  in  1997.  As  a

      $121,000  and  $77,000,  respectively,  were  related to  decreases in the
      volumes  of oil and gas  sold and  approximately  $159,000  and  $126,000,
      respectively,  were related to decreases in the average  prices of oil and
      gas sold.  Volumes of oil and gas sold decreased  6,225 barrels and 32,605
      Mcf,  respectively,  for the  nine  months  ended  September  30,  1998 as
      compared to the nine months  ended  September  30,  1997.  The decrease in
      volumes of oil sold resulted  primarily from (i) the sale of several wells
      in 1997 and 1998,  (ii) normal  declines in production  due to diminishing
      reserves on several  wells and (iii) the  shutting  in of two  significant
      wells for repairs and  maintenance  during the nine months ended September
      30,  1998.  Average oil and gas prices  decreased to $12.50 per barrel and
      $2.04 per Mcf, respectively,  for the nine months ended September 30, 1998
      from  $19.40  per  barrel  and $2.35 per Mcf,  respectively,  for the nine
      months ended September 30, 1997.

      As discussed in Liquidity and Capital Resources above, the I-F Partnership
      sold certain oil and gas properties during the nine months ended September
      30,  1998 and  recognized  a $335,669  gain on such sales.  Similar  sales
      during the nine  months  ended  September  30,  1997  resulted  in the I-F
      Partnership recognizing similar gains totaling $46,356.

      Oil and gas production  expenses  (including lease operating  expenses and
      production  taxes)  decreased  $190,188  (33.1%) for the nine months ended
      September  30, 1998 as compared to the nine  months  ended  September  30,
      1997. This decrease  resulted  primarily from (i) the decreases in volumes
      of oil and gas sold during the nine  months  ended  September  30, 1998 as
      compared to the nine months ended  September 30, 1997,  (ii) a decrease in
      production  taxes  associated with the decrease in oil and gas sales,  and
      (iii)  workover  expenses  incurred  on several  wells in 1997 in order to
      improve the recovery of reserves. As a percentage of oil and gas sales,

      these expenses  decreased to 35.0% for the nine months ended September 30,
      1998 from 36.3% for the nine months ended September 30, 1997.

      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
      decreased  $26,147 (13.9%) for the nine months ended September 30, 1998 as
      compared  to the nine months  ended  September  30,  1997.  This  decrease
      resulted  primarily  from  decreases in volumes of oil and gas sold during
      the nine months  ended  September  30, 1998 as compared to the nine months
      ended  September  30,  1997.  As a percentage  of oil and gas sales,  this
      expense  increased to 14.7% for the nine months ended  September  30, 1998
      from 11.9% for the nine months ended  September 30, 1997.  This percentage
      increase was primarily  due to the decreases in the average  prices of oil
      and gas sold during the nine months ended  September  30, 1998 as compared
      to the nine months ended September 30, 1997.

      The I-F  Partnership  recognized  a non-cash  charge  against  earnings of
      $114,631  during the nine months ended September 30, 1997. Of this amount,
      $20,908 was related to the decline in oil and gas prices used to determine
      the  recoverability  of proved oil and gas  reserves at March 31, 1997 and
      $93,723  was related to the  writing  off of  unproved  properties.  These
      unproved  properties  were  written  off  based on the  General  Partner's
      determination that it was unlikely that such properties would be developed
      due to the low oil and gas prices  received  over the prior  several years
      and provisions in the I-F Partnership's  Partnership Agreement which limit
      the  level  of  permissible  drilling  activity.  No  similar  charge  was
      necessary during the nine months ended September 30, 1998.

      General and  administrative  expenses decreased $2,813 (2.0%) for the nine
      months  ended  September  30, 1998 as  compared  to the nine months  ended
      September 30, 1997. As a percentage of oil and gas sales,  these  expenses
      increased to 12.5% for the nine months ended  September 30, 1998 from 8.8%
      for the nine months ended September 30, 1997. This percentage increase was
      primarily due to the decrease in oil and gas sales.

      The Limited Partners have received cash  distributions  through  September
      30, 1998  totaling  $17,747,664  or 123.93% of Limited  Partners'  capital
      contributions.
