      Oil and Gas Program 1984-1 Limited  Partnership (the  "Program"),  without
      audit.  In the opinion of management all  adjustments  (which include only
      normal  recurring  adjustments)  necessary to present fairly the financial
      position at June 30,  2001,  results of  operations  for the three and six
      months ended June 30, 2001 and 2000, and changes in cash flows for the six
      months ended June 30, 2001 and 2000 have been made.

      Information  and  footnote  disclosures  normally  included  in  financial
      statements  prepared in  accordance  with  generally  accepted  accounting
      principles  have been  condensed or omitted.  It is  suggested  that these
      financial  statements be read in conjunction with the financial statements
      and notes thereto included in the Program's Annual Report on Form 10-K for
      the year ended December 31, 2000. The results of operations for the period
      ended June 30, 2001 are not  necessarily  indicative  of the results to be
      expected for the full year.

      OIL AND GAS PROPERTIES
      ----------------------

      Oil and gas  operations  are  accounted  for using the full cost method of
      accounting.  All productive and  non-productive  costs associated with the
      acquisition,  exploration  and  development  of oil and gas  reserves  are
      capitalized.  The Program's  calculation of depreciation,  depletion,  and
      amortization  includes  estimated  future  expenditures  to be incurred in
      developing  proved  reserves and estimated  dismantlement  and abandonment
      costs, net of estimated  salvage values. In the event the unamortized cost
      of oil and gas properties  being  amortized  exceeds the full cost ceiling
      (as defined by the  Securities  and  Exchange  Commission),  the excess is
      charged to expense in the period  during which such excess  occurs.  Sales
      and  abandonments  of  properties  are  accounted  for as  adjustments  of
      capitalized costs with no gain or loss recognized, unless such adjustments
      would significantly  alter the relationship  between capitalized costs and
      proved oil and gas reserves.



                                      -6-
<PAGE>




      The provision for depreciation, depletion, and amortization of oil and gas
      properties is calculated by dividing the oil and gas sales dollars  during
      the  period by the  estimated  future  gross  income  from the oil and gas
      properties and applying the resulting  rate to the net remaining  costs of
      oil and gas properties that have been  capitalized,  plus estimated future
      development costs.


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

      Under the terms of the Program's partnership  agreement,  Dyco is entitled
      to  receive a  reimbursement  for all  direct  expenses  and  general  and
      administrative, geological and engineering expenses it incurs on behalf of
      the Program.  During the three  months  ended June 30, 2001 and 2000,  the
      Program incurred such expenses totaling $13,447 and $13,307, respectively,
      of which $12,006 was paid each period to Dyco and its  affiliates.  During
      the six months  ended June 30, 2001 and 2000,  the Program  incurred  such
      expenses totaling $35,609 and $33,897,  respectively, of which $24,012 was
      paid each period to Dyco and its affiliates.

      Affiliates of the Program  operate  certain of the  Program's  properties.
      Their  policy is to bill the  Program for all  customary  charges and cost
      reimbursements associated with these activities.

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 Program.

      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.


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

      Net  proceeds  from the  Program's  operations  less  necessary  operating
      capital  are  distributed  to  investors  on a  quarterly  basis.  The net
      proceeds from production are not reinvested in productive  assets,  except
      to the extent  that  producing  wells are  improved  or where  methods are
      employed to permit more efficient recovery of the Program's reserves which
      would result in a positive economic impact.




                                      -8-
<PAGE>




      The Program's  available capital from  subscriptions has been spent on oil
      and gas  drilling  activities.  There  should not be any further  material
      capital resource commitments in the future. However, during the six months
      ended June 30, 2000 the Program paid  recompletion  costs of approximately
      $52,000 on the Hubbard No. 1-A well located in Beckham County, Oklahoma in
      which  the  Program  owns an  interest  of  20.9%.  The  recompletion  was
      successful. The Program has no debt commitments.  Management believes that
      cash for ordinary operational purposes will be provided by current oil and
      gas production.


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

      Due to the volatility of oil and gas prices,  forecasting future prices is
      subject to great  uncertainty  and  inaccuracy.  Substantially  all of the
      Program's 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.  Such spot market
      sales are  generally  short-term  in  nature  and are  dependent  upon the
      obtaining of transportation services provided by pipelines. It is likewise
      difficult  to  predict  production  volumes.  However,  oil  and  gas  are
      depleting  assets,  so it can be  expected  that  production  levels  will
      decline  over  time.   Gas  prices  in  late  2000  and  early  2001  were
      significantly  higher  than  the  Program's  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. In the last few months spot gas prices have  generally  declined
      month to month.  It is not possible to accurately  predict  future pricing
      direction.

      THREE MONTHS  ENDED JUNE 30, 2001  COMPARED TO THE THREE MONTHS ENDED JUNE
      30, 2000.

                                                Three Months Ended June 30,
                                                ---------------------------
                                                     2001           2000
                                                   --------       --------
      Oil and gas sales                            $112,304       $192,209
      Oil and gas production expenses              $ 11,802       $ 29,259
      Barrels produced                                  173            355
      Mcf produced                                   24,721         53,682
      Average price/Bbl                            $  26.46       $  28.01
      Average price/Mcf                            $   4.36       $   3.40

      As shown in the table  above,  total oil and gas sales  decreased  $79,905
      (41.6%) for the three  months ended June 30, 2001 as compared to the three
      months ended June 30, 2000. Of this  decrease,  approximately  $98,000 was
      related to a decrease in volumes of gas sold.  This decrease was partially
      offset by an increase of  approximately  $24,000 related to an increase in
      the average price of gas sold.  Volumes of oil and gas sold  decreased 182
      barrels and 28,961 Mcf, respectively,  for the three months ended June 30,
      2001 as compared to the three months ended June 30, 2000.  The decrease in
      volumes of oil sold was  primarily  due to (i) a decline in  production on
      one  significant  well following the successful  recompletion of that well
      during the first  quarter of 2000 and (ii) the sale of another well during
      early 2000. The decrease in volumes of gas sold was primarily due to (i) a
      decline in production on one  significant  well  following the  successful
      recompletion  of that well  during  the first  quarter  of 2000,  (ii) the
      receipt  of a reduced  percentage  of sales on two wells  during the three
      months ended June 30, 2001 due to gas balancing,  and (iii) the receipt of
      an  increased  percentage  of sales on two wells  during the three  months
      ended June 30, 2000 due to gas balancing. As of the date of this Quarterly
      Report,  Management  does not know whether the gas  balancing  adjustments
      will continue in the future,  thereby  continuing to affect volumes of gas
      produced.  Average oil prices decreased to $26.46 per barrel for the three
      months  ended June 30,  2001 from  $28.01 per barrel for the three  months
      ended June 30, 2000. Average gas prices increased to $4.36 per Mcf for the
      three  months  ended June 30, 2001 from $3.40 per Mcf for the three months
      ended June 30, 2000.

      Oil and gas production  expenses  (including lease operating  expenses and
      production  taxes)  decreased  $17,457  (59.7%) for the three months ended
      June 30, 2001 as compared to the three months  ended June 30,  2000.  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
      production tax refund received during the three



                                      -10-
<PAGE>



      months  ended June 30,  2001,  and (iii) a decrease  in  production  taxes
      associated  with the decrease in oil and gas sales. As a percentage of oil
      and gas sales,  these  expenses  decreased  to 10.5% for the three  months
      ended June 30, 2001 from 15.2% for the three  months  ended June 30, 2000.
      This  percentage  decrease was primarily due to the dollar decrease in oil
      and gas  production  expenses and the increase in the average price of gas
      sold.

      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
      increased  $7,664  (118.0%)  for the three  months  ended June 30, 2001 as
      compared  to the three  months  ended June 30,  2000.  This  increase  was
      primarily  due to a  decrease  in the gas price used in the  valuation  of
      reserves at June 30, 2001 as compared to June 30, 2000.  This increase was
      partially   offset  by  a  decrease  in   depreciation,   depletion,   and
      amortization  due to the  decreases  in volumes of oil and gas sold.  As a
      percentage of oil and gas sales,  this expense  increased to 12.6% for the
      three months ended June 30, 2001 from 3.4% for the three months ended June
      30,  2000.  This  percentage  increase  was  primarily  due to the  dollar
      increase in depreciation, depletion, and amortization.

      General and  administrative  expenses  increased $140 (1.1%) for the three
      months  ended June 30, 2001 as compared to the three months ended June 30,
      2000. As a percentage of oil and gas sales,  these  expenses  increased to
      12.0% for the three  months  ended  June 30,  2001 from 6.9% for the three
      months ended June 30, 2000. This percentage  increase was primarily due to
      the decrease in oil and gas sales.

      SIX MONTHS  ENDED JUNE 30, 2001  COMPARED TO THE SIX MONTHS ENDED JUNE 30,
      2000.

      Oil and gas sales                            $323,615       $307,940
      Oil and gas production expenses              $ 35,735       $ 56,477
      Barrels produced                                  320            565
      Mcf produced                                   52,718         98,129
      Average price/Bbl                            $  27.19       $  27.60
      Average price/Mcf                            $   5.97       $   2.98

      As shown in the table  above,  total oil and gas sales  increased  $15,675
      (5.1%)  for the six  months  ended June 30,  2001 as  compared  to the six
      months ended June 30, 2000. Of this increase,  approximately  $158,000 was
      related to an increase in the average price of gas sold. This increase was
      partially  offset by  decreases  of  approximately  $7,000  and  $135,000,
      respectively, related to decreases in volumes of oil and gas sold. Volumes
      of oil and gas sold decreased



                                      -11-
<PAGE>



      245 barrels and 45,411 Mcf,  respectively,  for the six months  ended June
      30, 2001 as compared to the six months ended June 30,  2000.  The decrease
      in volumes of oil sold was primarily due to (i) a decline in production on
      one  significant  well following the successful  recompletion of that well
      during the first  quarter of 2000 and (ii) the sale of another well during
      early 2000. The decrease in volumes of gas sold was primarily due to (i) a
      decline in production on one  significant  well  following the  successful
      recompletion  of that well  during  the first  quarter  of 2000,  (ii) the
      Program's receipt of a reduced percentage of sales on two wells during the
      six  months  ended  June 30,  2001 due to gas  balancing,  and  (iii)  the
      Program's receipt of an increased  percentage of sales on two wells during
      the six  months  ended June 30,  2000 due to gas  balancing.  Average  oil
      prices  decreased  to $27.19 per barrel for the six months  ended June 30,
      2001 from  $27.60  per barrel  for the six  months  ended  June 30,  2000.
      Average  gas prices  increased  to $5.97 per Mcf for the six months  ended
      June 30, 2001 from $2.98 per Mcf for the six months ended June 30, 2000.

      Oil and gas production  expenses  (including lease operating  expenses and
      production  taxes) decreased $20,742 (36.7%) for the six months ended June
      30, 2001 as compared to the six months ended June 30, 2000.  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 production  tax
      refund  received  during the six months  ended  June 30,  2001,  and (iii)
      workover  expenses  incurred on one well during the six months  ended June
      30, 2000 in order to improve the recovery of reserves.  As a percentage of
      oil and gas sales,  these  expenses  decreased to 11.0% for the six months
      ended June 30,  2001 from 18.3% for the six  months  ended June 30,  2000.
      This percentage  decrease was primarily due to the increase in the average
      price  of gas  sold  and the  dollar  decrease  in oil and gas  production
      expenses.

      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
      increased  $6,014  (32.8%)  for the six  months  ended  June  30,  2001 as
      compared  to the six  months  ended  June  30,  2000.  This  increase  was
      primarily  due to (i) the  increase in the  average  price of gas sold and
      (ii) a decrease in the gas price used in the valuation of reserves at June
      30, 2001 as compared to June 30,  2000.  These  increases  were  partially
      offset by a decrease in depreciation,  depletion,  and amortization due to
      the  decreases in volumes of oil and gas sold.  As a percentage of oil and
      gas sales,  this  expense  increased to 7.5% for the six months ended June
      30, 2001 from 5.9% for the six months ended June 30, 2000. This percentage
      increase  was  primarily  due  to the  dollar  increase  in  depreciation,
      depletion, and amortization.

      General and administrative  expenses increased $1,712 (5.1%) for the six
      months ended June 30, 2001 as compared to the

      six months  ended June 30,  2000.  As a  percentage  of oil and gas sales,
      these  expenses  remained  constant at 11.0% for the six months ended June
      30, 2001 and the six months ended June 30, 2000.
