      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  proceeds  are credited to oil and gas
      properties.

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-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, 2000 and the net revenue
      generated from future operations will provide  sufficient  working capital
      to meet current and future obligations.


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
      variables affecting the Partnerships' revenues are the prices received for
      the  sale of oil and gas and  the  volumes  of oil and gas  produced.  The
      Partnerships'  production  is mainly  natural  gas,  so such  pricing  and
      volumes are the most significant factors.




                                      -20-
<PAGE>




      Due to the volatility of oil and gas prices,  forecasting future prices is
      subject to great  uncertainty  and  inaccuracy.  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.
      However,  oil and gas are  depleting  assets,  so it can be expected  that
      production  levels  will  decline  over time.  Recent gas prices have been
      significantly  higher than the Partnerships'  historical average.  This is
      attributable to the higher prices for crude oil, a substitute fuel in some
      markets,  and reduced production due to lower capital  investments in 1998
      and 1999.

      Oil and gas sales                           $370,080         $250,390
      Oil and gas production expenses             $ 52,802         $ 39,158
      Barrels produced                               1,508            2,577
      Mcf produced                                  79,570           82,545
      Average price/Bbl                           $  33.18         $  17.61
      Average price/Mcf                           $   4.02         $   2.48

      As shown in the table above,  total oil and gas sales  increased  $119,690
      (47.8%) for the three months ended  September  30, 2000 as compared to the
      three months ended  September  30, 1999. Of this  increase,  approximately
      $23,000 and  $122,000,  respectively,  were  related to  increases  in the
      average prices of oil and gas sold.  These increases were partially offset
      by a decrease of approximately $19,000 related to a decrease in volumes of
      oil sold.  Volumes of oil and gas sold  decreased  1,069 barrels and 2,975
      Mcf,  respectively,  for the three  months  ended  September  30,  2000 as
      compared to the three months  ended  September  30, 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 the three months  ended  September  30,  1999.  Average oil and gas
      prices increased to $33.18 per barrel and $4.02 per Mcf, respectively, for
      the three months ended September 30, 2000 from $17.61 per barrel and $2.48
      per Mcf, respectively, for the three months ended September 30, 1999.

      Oil and gas production  expenses  (including lease operating  expenses and
      production  taxes)  increased  $13,644  (34.8%) for the three months ended
      September  30, 2000 as compared to the three  months ended  September  30,
      1999.  This  increase was  primarily  due to (i) an increase in production
      taxes  associated with the increase in oil and gas sales and (ii) workover
      expenses  incurred on one  significant  well during the three months ended
      September 30, 2000. As a percentage of oil and gas sales,  these  expenses
      decreased  to 14.3% for the three  months  ended  September  30, 2000 from
      15.6% for the three months ended September 30, 1999.

      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
      increased  $2,169 (14.1%) for the three months ended September 30, 2000 as
      compared to the three months ended  September 30, 1999.  This increase was
      primarily  due to downward  revisions in the  estimates  of remaining  gas
      reserves on three  significant  wells at December 31, 1999.  This increase
      was partially offset by the decreases in volumes of oil and gas sold. As a
      percentage  of oil and gas sales,  this expense  decreased to 4.7% for the
      three months ended September 30, 2000 from 6.2% for the three months ended
      September  30, 1999.  This  percentage  decrease was  primarily due to the
      increases in the average prices of oil and gas sold.

      General and administrative  expenses increased $1,323 (6.3%) for the three
      months  ended  September  30, 2000 as compared to the three  months  ended
      September 30, 1999. As a percentage of oil and gas sales,  these  expenses
      decreased to 6.0% for the three months ended  September 30, 2000 from 8.4%
      for the three months ended September 30, 1999.  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  increased  $385,927
      (67.4%) for the nine months  ended  September  30, 2000 as compared to the
      nine months ended  September  30, 1999.  Of this  increase,  approximately
      $86,000

<PAGE>



      and  $314,000,  respectively,  were  related to  increases  in the average
      prices of oil and gas sold.  Volumes of oil sold decreased  2,320 barrels,
      while  volumes of gas sold  increased  9,176 Mcf for the nine months ended
      September  30, 2000 as compared to the nine  months  ended  September  30,
      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 the nine months ended September 30, 1999.
      Average  oil and gas prices  increased  to $31.10 per barrel and $3.29 per
      Mcf,  respectively,  for the nine  months  ended  September  30, 2000 from
      $14.10  per barrel and $2.00 per Mcf,  respectively,  for the nine  months
      ended September 30, 1999.

      Oil and gas production  expenses  (including lease operating  expenses and
      production  taxes)  increased  $66,425  (57.5%) for the nine months  ended
      September  30, 2000 as compared to the nine  months  ended  September  30,
      1999. This increase was primarily due to (i) workover expenses incurred on
      one  significant  well during the nine months ended  September 30, 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  another  significant  well  during  the three  months  ended
      September 30, 1999. As a percentage of oil and gas sales,  these  expenses
      decreased to 19.0% for the nine months ended September 30, 2000 from 20.2%
      for the nine months ended September 30, 1999.

      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
      increased  $8,801 (19.4%) for the nine months ended  September 30, 2000 as
      compared to the nine months ended  September  30, 1999.  This increase was
      primarily  due to downward  revisions in the  estimates  of remaining  gas
      reserves on three  significant wells at December 31, 1999. As a percentage
      of oil and gas sales,  this expense  decreased to 5.7% for the nine months
      ended September 30, 2000 from 7.9% for the nine months ended September 30,
      1999. This  percentage  decrease was primarily due to the increases in the
      average prices of oil and gas sold.

      General and  administrative  expenses increased $1,673 (2.4%) for the nine
      months  ended  September  30, 2000 as  compared  to the nine months  ended
      September 30, 1999. As a percentage of oil and gas sales,  these  expenses
      decreased to 7.4% for the nine months ended  September 30, 2000 from 12.1%
      for the nine months ended September 30, 1999. This percentage decrease was
      primarily due to the increase in oil and gas sales.

      The Limited Partners have received cash  distributions  through  September
      30, 2000  totaling  $14,888,175  or 206.93% of Limited  Partners'  capital
      contributions.

      As shown in the table above,  total oil and gas sales  increased  $656,718
      (52.4%) for the three months ended  September  30, 2000 as compared to the
      three months ended  September  30, 1999. Of this  increase,  approximately
      $112,000  and  $620,000,  respectively,  were  related to increases in the
      average prices of oil and gas sold.  These increases were partially offset
      by a decrease of approximately $66,000 related to a decrease in volumes of
      gas sold.  Volumes of oil and gas sold  decreased  486  barrels and 27,435
      Mcf,  respectively,  for the three  months  ended  September  30,  2000 as
      compared to the three months ended September 30, 1999. Average oil and gas
      prices increased to $28.37 per barrel and $4.02 per Mcf, respectively, for
      the three months ended September 30, 2000 from $19.65 per barrel and $2.41
      per Mcf, respectively, for the three months ended September 30, 1999.

      Oil and gas production  expenses  (including lease operating  expenses and
      production  taxes)  increased  $60,109  (22.3%) for the three months ended
      September  30, 2000 as compared to the three  months ended  September  30,
      1999.  This increase was primarily due to an increase in production  taxes
      associated  with the increase in oil and gas sales. As a percentage of oil
      and gas sales,  these  expenses  decreased  to 17.3% for the three  months
      ended  September 30, 2000 from 21.5% for the three months ended  September
      30, 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 $15,600 (10.0%) for the three months ended September 30, 2000 as
      compared to the three months ended  September 30, 1999.  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.  As a  percentage  of oil and gas sales,  this expense
      decreased to 7.3% for the three

      months  ended  September  30, 2000 from 12.4% for the three  months  ended
      September  30, 1999.  This  percentage  decrease was  primarily due to the
      increases in the average prices of oil and gas sold.

      General and administrative  expenses increased $3,145 (2.6%) for the three
      months  ended  September  30, 2000 as compared to the three  months  ended
      September 30, 1999. As a percentage of oil and gas sales,  these  expenses
      decreased to 6.5% for the three months ended  September 30, 2000 from 9.7%
      for the three months ended September 30, 1999.  This  percentage  decrease
      was primarily due to the increase in oil and gas sales.

      (68.3%) for the nine months  ended  September  30, 2000 as compared to the
      nine months ended  September  30, 1999.  Of this  increase,  approximately
      $549,000 and  $1,460,000,  respectively,  were related to increases in the
      average prices of oil and gas sold.  Volumes of oil sold  decreased  3,655
      barrels,  while  volumes  of gas sold  increased  14,996  Mcf for the nine
      months  ended  September  30, 2000 as  compared  to the nine months  ended

      ended  September  30, 2000 from 28.5% for the nine months ended  September
      30, 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
      remained  relatively constant for the nine months ended September 30, 2000

      (27.9%) for the three months ended  September  30, 2000 as compared to the
      three months ended  September  30, 1999.  Of this  increase  approximately
      $53,000 and  $132,000,  respectively,  were  related to  increases  in the
      average prices of oil and gas sold.  These increases were partially offset
      by a decrease of approximately $69,000 related to a decrease in volumes of

      respectively, for the three months ended September 30, 2000 as compared to
      the three months ended  September 30, 1999. The decrease in volumes of gas
      sold was  primarily due to (i) positive  prior period  volume  adjustments
      made by the purchaser on three  significant  wells during the three months
      ended September 30, 1999 and (ii) normal  declines in production.  Average
      oil and gas  prices  increased  to $28.25  per  barrel  and $4.10 per Mcf,
      respectively,  for the three months ended  September  30, 2000 from $19.40

      months  ended  September  30, 2000 and  recognized  a $63,355 gain on such
      sales.  Sales of oil and gas  properties  during  the three  months  ended
      September 30, 1999  resulted in the I-F  Partnership  recognizing  similar
      gains of $546.

      Oil and gas production  expenses  (including lease operating  expenses and
      production  taxes)  increased  $8,192  (6.7%) for the three  months  ended
      September  30, 2000 as compared to the three  months ended  September  30,
      1999. As a percentage of oil and gas sales,  these  expenses  decreased to
      25.1% for the three  months  ended  September  30, 2000 from 30.1% for the
      three  months  ended  September  30, 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 $15,941 (31.9%) for the three months ended September 30, 2000 as
      compared to the three months ended  September 30, 1999.  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.  As a  percentage  of oil and gas sales,  this expense

      (59.3%) for the nine months  ended  September  30, 2000 as compared to the
      nine months ended  September  30, 1999.  Of this  increase,  approximately
      $274,000  and  $347,000,  respectively,  were  related to increases in the
      average prices of oil and gas sold.  Volumes of oil and gas sold decreased
      1,513  barrels and 25,938  Mcf,  respectively,  for the nine months  ended
      September  30, 2000 as compared to the nine  months  ended  September  30,
      1999.  Average oil and gas prices increased to $28.61 per barrel and $3.34

      September  30, 2000 as compared to the nine  months  ended  September  30,
      1999.  This  increase was  primarily  due to (i) an increase in production
      taxes  associated  with the  increase  in oil and gas  sales,  (ii)  legal
      expenses  incurred on one  significant  well during the nine months  ended
      September  30, 2000,  and (iii)  positive  prior  period  lease  operating
      expense  adjustments made by the operator on several wells during the nine

      these expenses  decreased to 27.6% for the nine months ended September 30,
      2000  from  36.0% for the nine  months  ended  September  30,  1999.  This
      percentage  decrease  was  primarily  due to the  increases in the average
      prices of oil and gas sold.
