      1999  have been  prepared  by Dyco  Petroleum  Corporation  ("Dyco"),  the
      General Partner of the Dyco 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 September 30, 2000,  results of
      operations  for the three and nine  months  ended  September  30, 2000 and
      1999,  and changes in cash flows for the nine months ended  September  30,
      2000 and 1999 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, 1999. The results of operations for the period
      ended September 30, 2000 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.  During the nine months ended September 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 a
      working  interest of  approximately  20.9%.  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



                                      -6-
<PAGE>



      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.

      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 September 30, 2000 and 1999 the
      Program incurred such expenses totaling $14,892 and $17,147, respectively,
      of which $12,006 and $15,654, respectively,  were paid each period to Dyco
      and its  affiliates.  During the nine months ended  September 30, 2000 and
      1999 the Program  incurred  such  expenses  totaling  $48,789 and $58,129,
      respectively, of which $36,018 and $46,962,  respectively,  were 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 nine
      months ended  September 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  a  working  interest  of
      approximately 20.9%. The recompletion was successful.  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. Recent gas prices have been  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.

      Oil and gas sales                            $186,590       $113,873
      Oil and gas production expenses              $ 33,370       $ 26,988

      Average price/Bbl                            $  47.11       $  21.44
      Average price/Mcf                            $   4.36       $   2.58

      As shown in the table  above,  total oil and gas sales  increased  $72,717
      (63.9%) for the three months ended  September  30, 2000 as compared to the
      three months ended  September  30, 1999. Of this  increase,  approximately
      $74,000  was  related to an  increase  in the  average  price of gas sold.
      Volumes  of  oil  and  gas  sold   decreased   173  barrels  and  80  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 $47.11 per barrel and $4.36 per Mcf,  respectively,  for the
      three months ended September 30, 2000 from $21.44 per barrel and $2.58 per
      Mcf, respectively, for the three months ended September 30, 1999.

      Oil and gas production  expenses  (including lease operating  expenses and
      production  taxes)  increased  $6,382  (23.6%) 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 17.9% for the three  months
      ended  September 30, 2000 from 23.7% 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
      increased  $2,047 (27.3%) for the three months ended September 30, 2000 as
      compared to the three months ended  September 30, 1999.  This increase was
      primarily due to the decreased dollar amount of  depreciation,  depletion,
      and  amortization  charged during the third quarter of 1999 which resulted
      from a  significant  increase  in the gas price used in the  valuation  of
      remaining  reserves at September 30, 1999 as compared to June 30, 1999. As
      a percentage of oil and gas sales,  this expense decreased to 5.1% for the
      three months ended September 30, 2000 from 6.6% for the three months ended
      September 30, 1999. This percentage decrease



                                      -10-
<PAGE>



      was primarily due to the increases in the average  prices of oil and gas
      sold.

      General and administrative expenses decreased $2,255 (13.2%) for the three
      months  ended  September  30, 2000 as compared to the three  months  ended
      September  30,  1999.  This  decrease  was  primarily  due to a change  in
      allocation  among the  Program and other  affiliated  programs of indirect
      general and  administrative  expenses  reimbursed to the General  Partner.
      This  decrease  was  partially  offset  by an  increase  primarily  due to
      accounting  review fees incurred  during the three months ended  September
      30, 2000 as a result of new ongoing requirements imposed by the Securities
      and  Exchange  Commission.  As a  percentage  of oil and gas sales,  these
      expenses  decreased to 8.0% for the three months ended  September 30, 2000
      from 15.1% for the three months ended  September  30, 1999.  This decrease
      was primarily due to the increase in oil and gas sales.

      Average price/Mcf                            $   3.39       $   2.09

      As shown in the table above,  total oil and gas sales  increased  $198,462
      (67.0%) for the nine months  ended  September  30, 2000 as compared to the
      nine months ended  September  30, 1999.  Of this  increase,  approximately
      $182,000  was related to an  increase  in the  average  price of gas sold.
      Volumes  of oil sold  decreased  256  barrels,  while  volumes of gas sold
      increased  4,929  Mcf 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 $30.40 per barrel and $3.39 per Mcf, respectively, for
      the nine months ended  September 30, 2000 from $15.59 per barrel and $2.09
      per Mcf, respectively, for the nine months ended September 30, 1999.

      Oil and gas production  expenses  (including lease operating  expenses and
      production  taxes)  increased  $17,759  (24.6%) for the nine months  ended
      September  30, 2000 as compared to the nine  months  ended  September  30,
      1999.  This increase was primarily due to an increase in production  taxes
      associated  with the increase of oil and gas sales. As a percentage of oil
      and gas sales, these expenses decreased to 18.2% for the

<PAGE>



      nine months ended  September 30, 2000 from 24.3% 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
      decreased  $7,225 (20.6%) for the nine months ended  September 30, 2000 as
      compared to the nine months ended  September  30, 1999.  This decrease was
      primarily due to (i) an increase in the gas price used in the valuation of
      remaining reserves at September 30, 2000 as compared to September 30, 1999
      and (ii) an upward  revision in the estimate of remaining  gas reserves at
      December 31,  1999.  As a  percentage  of oil and gas sales,  this expense
      decreased to 5.6% for the nine months ended  September 30, 2000 from 11.9%
      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
      and the dollar decrease in depreciation, depletion, and amortization.

      General and administrative  expenses decreased $9,340 (16.1%) for the nine
      months  ended  September  30, 2000 as  compared  to the nine months  ended
      September  30,  1999.  This  decrease  was  primarily  due to a change  in
      allocation  among the  Program and other  affiliated  programs of indirect
      general and administrative  expenses reimbursed to the General Partner. As
      a percentage of oil and gas sales,  these  expenses  decreased to 9.9% for
      the nine months  ended  September  30, 2000 from 19.6% for the nine months
      ended September 30, 1999.  This  percentage  decrease was primarily due to
      the increase in oil and gas sales.
