                                     PART I


ITEM 1.   BUSINESS

      General

      The Dyco Oil and Gas Program 1978-1 Limited Partnership (the "Program") is
a Minnesota  limited  partnership  engaged in the production of oil and gas. The
Program  commenced  operations  on April 1,  1978  with  the  primary  financial
objective of investing its limited  partners'  subscriptions  in the drilling of
oil  and gas  prospects  and  then  distributing  to its  limited  partners  all
available  cash flow from the Program's  on-going  production  operations.  Dyco
Petroleum  Corporation  ("Dyco")  serves as the General  Partner of the Program.
Samson  Resources  Company,  an  affiliate  of Dyco,  currently  owns  more than
one-half of the  Program's  Units of limited  partnership  interest,  making the
Program a 50% subsidiary of Samson Resources  Company.  See "Item 2. Properties"
for a description of the Program's reserves and properties.

      The  limited   partnership   agreement   for  the  Program  (the  "Program
Agreement")  provides  that limited  partners are  allocated  99% of all Program
costs and revenues and Dyco, as General Partner,  is allocated 1% of all Program
costs and  revenues.  Included in such costs is the Program's  reimbursement  to
Dyco of the Program's proportionate share of Dyco's geological, engineering, and
general and administrative expenses.

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

      As a limited  partnership,  the Program  has no  officers,  directors,  or
employees. It relies instead on the personnel of Dyco and Samson. As of February
15, 2001, Samson employed approximately 965 persons. No employees are covered by
collective bargaining agreements, and management believes that Samson provides a
sound employee relations  environment.  For information  regarding the executive
officers  of Dyco,  see  "Item  10.  Directors  and  Executive  Officers  of the
Registrant."

      Dyco's and the Program's  principal place of business is located at Samson
Plaza, Two West Second Street, Tulsa, Oklahoma 74103, and their telephone number
is (918) 583-1791 or (800) 283-1791.


      Funding

      Although the Program  Agreement  permits the Program to incur  borrowings,
the Program's  operations and expenses are currently funded out of the Program's
revenues from oil and gas sales. Dyco may, but is not required to, advance funds
to  the  Program  for  the  same  purposes  for  which  Program  borrowings  are
authorized.


      Principal Products Produced and Services Rendered

      The Program's sole business is the  development  and production of oil and
gas with a  concentration  on gas.  The  Program  does  not  hold  any  patents,
trademarks,  licenses,  or  concessions  and is not a  party  to any  government
contracts.  The  Program  has no backlog of orders and does not  participate  in
research and development  activities.  The Program is not presently encountering
shortages of oilfield tubular goods, compressors,  production material, or other
equipment.


      Oil, Gas, and Environmental Control Regulations

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

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




                                      -4-
<PAGE>



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

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


      Significant Customers

      Purchases of gas by El Paso Energy Marketing Company ("El Paso") accounted
for approximately 94.9% of the Program's oil and gas sales during the year ended
December 31, 2000. In the event of interruption of purchases by this significant
customer or the  cessation or material  change in  availability  of  open-access
transportation by the Program's pipeline transporters, the Program may encounter
difficulty  in  marketing  its gas and in  maintaining  historic  sales  levels.
Alternative purchasers or transporters may not be readily available.

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


      Competition and Marketing

      The Program's revenues,  net income or loss, cash flows, carrying value of
oil and gas  properties,  and  amount of oil and gas  which can be  economically
produced depend  substantially  upon the prevailing  prices for oil and gas. Oil
and gas prices (and consequently the Program's profitability) depend on a number
of factors that are beyond the control of the  Program.  These  factors  include
worldwide political instability  (especially in oil-producing  regions),  United
Nations  export  embargoes,  the supply and price of foreign  imports of oil and
gas, the level of consumer  product  demand (which can be heavily  influenced by
weather  patterns),  the level of domestic  oil and gas  production,  government
regulations  and taxes,  the price and  availability of alternative  fuels,  the
overall economic environment, and the



                                      -5-
<PAGE>



availability  and capacity of  transportation  and  processing  facilities.  The
effect  of these  factors  on  future  oil and gas  industry  trends  cannot  be
accurately  predicted  or  anticipated.  In  addition,  the domestic oil and gas
industry is highly competitive, with a large number of companies and individuals
engaged in the exploration and development of oil and gas properties. Predicting
future prices is not possible. Concerning past trends, oil and gas prices in the
United States have been highly volatile for many years.

      Over the past ten years average yearly  wellhead gas prices have generally
been in the $1.40 to $2.40 per Mcf range.  However,  due to  unusual  supply and
demand  circumstances  gas prices are  currently  substantially  higher than the
upper end of this range.  Substantially  all of the  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. In addition, such spot market sales are generally short-term
in nature and are dependent upon obtaining  transportation  services provided by
pipelines.  Spot prices for gas increased  from  approximately  $2.34 per Mcf at
December 31, 1999 to  approximately  $9.23 per Mcf at December  31,  2000.  Such
prices were on an MMBTU basis and differ  from the prices  actually  received by
the Program due to  transportation  and marketing costs,  BTU  adjustments,  and
regional price and quality differences.

      For the past ten years,  average  oil prices  have  generally  been in the
$16.00 to $24.00 per barrel  range,  but have been  extremely  volatile over the
past three  years.  Due to global  consumption  and  supply  trends as well as a
slowdown in Asian energy demand,  oil prices in late 1997 and early 1998 reached
historically low levels,  dropping to as low as approximately  $9.25 per barrel.
However, production curtailment agreements among major oil producing nations and
other supply and demand  factors have caused  recent oil prices to climb to over
$30.00  per  barrel in some  markets.  It is not known  whether  this trend will
continue.  Prices  for oil  increased  from  approximately  $22.75 per barrel at
December 31, 1999 to approximately $23.75 per barrel at December 31, 2000.

      Future  prices  for both oil and gas will  likely  be  different  from the
prices in effect on December 31, 2000. While it is impossible to predict whether
future oil and gas prices will (i) stabilize,  (ii) increase, or (iii) decrease,
management believes it is unlikely that future oil and gas prices will remain as
high as those experienced at December 31, 2000.


      Insurance Coverage

     The Program is subject to all of the risks inherent in the  exploration for
and production of oil and gas, including blowouts,  pollution,  fires, and other
casualties. The Program



                                      -6-
<PAGE>



maintains  insurance  coverage as is  customary  for  entities of a similar size
engaged in operations similar to that of the Program,  but losses can occur from
uninsurable risks or in amounts in excess of existing  insurance  coverage.  The
occurrence  of an event  which is not fully  covered by  insurance  could have a
material  adverse  effect on the  Program's  financial  condition and results of
operations.

----------

(1)   The designation of a well as an oil well or gas well is made by Dyco based
      on the relative amount of oil and gas reserves for the well. Regardless of
      a well's oil or gas designation,  it may produce oil, gas, or both oil and
      gas.
(2)   As used throughout this Annual Report on Form 10-K405  ("Annual  Report"),
      "Gross  Well" refers to a well in which a working  interest is owned.  The
      number  of gross  wells is the  total  number  of wells in which a working
      interest is owned.
(3)   As used throughout this Annual Report, "Net Well" refers to the sum of the
      fractional  working  interests  owned in gross wells.  For example,  a 15%
      working interest in a well represents one Gross Well, but 0.15 Net Well.


      Drilling Activities

      The Program  participated in no drilling  activities during the year ended
December 31, 2000.

<PAGE>



      energy content of gas and oil, which rate is not necessarily indicative of
      the relationship of oil and gas prices.  The respective  prices of oil and
      gas are  affected  by market and other  factors in  addition  to  relative
      energy content.

      Proved Reserves and Net Present Value

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

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

      The process of  estimating  oil and gas  reserves  is  complex,  requiring
significant  subjective  decisions in the  evaluation  of available  geological,
engineering,  and  economic  data  for  each  reservoir.  The  data  for a given
reservoir may change substantially over time as a result of, among other things,
additional development activity, production history, and viability of production
under varying economic conditions;  consequently, it is reasonably possible that
material revisions to existing reserve estimates may occur in the near future.

Although  every  reasonable  effort has been made to ensure  that these  reserve
estimates represent the most accurate assessment  possible,  the significance of
the  subjective  decisions  required and variances in available data for various
reservoirs  make these  estimates  generally  less precise than other  estimates
presented in connection with financial statement disclosures.


                               Proved Reserves and
                               Net Present Value
                             From Proved Reserves

                          As of December 31, 2000 (1)

            Estimated proved reserves:
              Gas (Mcf)                                    354,028
              Oil and liquids (Bbls)                           756

            Net present value
              (discounted at 10% per annum)             $1,376,065

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

(1)   Includes certain gas balancing adjustments which cause the gas volumes and
      net present value to differ from the reserve reports  prepared by Dyco and
      reviewed by Ryder Scott.


      No estimates  of the proved  reserves of the Program  comparable  to those
included  herein have been included in reports to any federal  agency other than
the SEC.  Additional  information  relating to the Program's  proved reserves is
contained in Note 5 to the Program's financial statements, included in Item 8 of
this Annual Report.


      Significant Properties

      As of December 31, 2000, the Program's properties consist of 11 gross (.37
net)  productive  wells.  The  Program  also owns a  non-working  interest in an
additional  12 wells.  Affiliates  of the  Program  operate 8 (35%) of its total
wells.  All of the  Program's  properties  are located in the Anadarko  Basin of
western  Oklahoma and the Texas  panhandle,  which is an established oil and gas
producing basin.


      Title to Oil and Gas Properties

      Management believes that the Program has satisfactory title to its oil and
gas properties. Record title to substantially all of the Program's properties is
held by Dyco as nominee.



                                      -10-
<PAGE>



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


ITEM 3.  LEGAL PROCEEDINGS

      On February 13, 1998,  Walter K. Spurlin  L.L.C.  filed a lawsuit  against
Dyco alleging that Dyco amended or terminated certain gas purchase contracts and
fraudulently  concealed the  settlement of these  contracts.  (Walter K. Spurlin
L.L.C., et al. vs. Dyco Petroleum Corporation,  CJ-98-3, District Court of Roger
Mills County,  Oklahoma.) The Plaintiff  filed the petition as a class action on
behalf of all individuals who leased Oklahoma  mineral leases to Dyco which were
subject  to certain  gas  purchase  contracts.  The  Plaintiff,  a lessor of the
Spurlin No. 1-23 well,  alleges that Dyco's actions  resulted in a breach of the
express and implied  obligations of the leases and reckless  indifference and/or
actual fraud on behalf of Dyco.  The  Plaintiff  has not specified the amount of
alleged  damages.  Dyco filed its answer in the matter on April 1, 1998 in which
it  denied  all  of  the  Plaintiff's  allegations  and  asserted  a  number  of
affirmative  defenses,  including  failure  to state a claim and  running of the
statute of  limitations.  Dyco's  affirmative  defenses  also  alleged  that the
Plaintiff's  claims were contrary to the Oklahoma  Supreme  Court's  decision in
Roye Realty and Developing,  Inc. v. Watson, 949 P.2d 1208 (Okla. 1996) and that
Dyco acted as a prudent operator and in accordance with the lease terms. A class
certification order was entered by the district court on February 25, 2000. Dyco
has filed an  interlocutory  appeal of this  order  which is  currently  pending
before the Oklahoma  Supreme Court.  The Program had an approximate 8.7% working
interest in the Spurlin  No.  1-23 well  during the periods  applicable  to this
lawsuit.

      Except for the  foregoing,  to the knowledge of the management of Dyco and
the Program, neither Dyco, the Program, nor the Program's properties are subject
to any  litigation,  the  results of which  would have a material  effect on the
Program's or Dyco's financial condition or operations.


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

      There  were  no  matters  submitted  to a vote  of the  Program's  limited
partners during 2000.

ITEM 5.   MARKET FOR THE REGISTRANT'S LIMITED PARTNERSHIP
          UNITS AND RELATED LIMITED PARTNER MATTERS

      The Program does not have an  established  trading market for its units of
limited  partnership  interest  ("Units").  Pursuant to the terms of the Program
Agreement, Dyco, as General Partner, is obligated to annually issue a repurchase
offer which is based on the  estimated  future net revenues  from the  Program's
reserves and is calculated pursuant to the terms of the Program Agreement.  Such
repurchase offer is recalculated  monthly in order to reflect cash distributions
made to the limited partners and extraordinary  events. The following table sets
forth,  for the  periods  indicated,  Dyco's  repurchase  offer per Unit and the
amount of the Program's  cash  distributions  per Unit for the same period.  For
purposes of this Annual Report,  a Unit  represents an initial  subscription  of
$5,000 to the Program.


                                    Repurchase                 Cash

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

      Use of Forward-Looking Statements and Estimates

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


     General Discussion

     The following  general  discussion  should be read in conjunction  with the
analysis of results of operations  provided below. The Program's  revenues,  net
income or loss, cash flows, carrying value of oil and gas properties, and amount
of oil and gas which can be economically  produced depend substantially upon the
prevailing  prices for oil and gas.  Oil and gas prices  (and  consequently  the
Program's  profitability)  depend on a number of  factors  that are  beyond  the
control of the Program.  These factors include worldwide  political  instability
(especially in  oil-producing  regions),  United Nations export  embargoes,  the
supply  and price of  foreign  imports  of oil and gas,  the  level of  consumer
product demand (which can be heavily influenced by weather patterns),  the level
of domestic oil and gas production,  government regulations and taxes, the price
and availability of alternative fuels, the overall economic environment, and the
availability  and capacity of  transportation  and  processing  facilities.  The
effect of these factors on future oil and gas



                                      -14-
<PAGE>



industry trends cannot be accurately predicted or anticipated.  In addition, the
domestic  oil and gas  industry is highly  competitive,  with a large  number of
companies and individuals  engaged in the exploration and development of oil and
gas  properties.  Predicting  future  prices is not  possible.  Concerning  past
trends,  oil and gas prices in the United  States have been highly  volatile for
many years.

      Over the past ten years average yearly  wellhead gas prices have generally
been in the $1.40 to $2.40 per Mcf range.  However,  due to  unusual  supply and
demand  circumstances  gas prices are  currently  substantially  higher than the
upper end of this range.  Substantially  all of the  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. In addition, such spot market sales are generally short-term
in nature and are dependent upon obtaining  transportation  services provided by
pipelines.  Spot prices for gas increased  from  approximately  $2.34 per Mcf at
December 31, 1999 to  approximately  $9.23 per Mcf at December  31,  2000.  Such
prices were on an MMBTU basis and differ  from the prices  actually  received by
the Program due to  transportation  and marketing costs,  BTU  adjustments,  and
regional price and quality differences.

      For the past ten years,  average  oil prices  have  generally  been in the
$16.00 to $24.00 per barrel  range,  but have been  extremely  volatile over the
past three  years.  Due to global  consumption  and  supply  trends as well as a
slowdown in Asian energy demand,  oil prices in late 1997 and early 1998 reached
historically low levels,  dropping to as low as approximately  $9.25 per barrel.
However, production curtailment agreements among major oil producing nations and
other supply and demand  factors have caused  recent oil prices to climb to over
$30.00  per  barrel in some  markets.  It is not known  whether  this trend will
continue.  Prices  for oil  increased  from  approximately  $22.75 per barrel at
December 31, 1999 to approximately $23.75 per barrel at December 31, 2000.

      Future  prices  for both oil and gas will  likely  be  different  from the
prices in effect on December 31, 2000. While it is impossible to predict whether
future oil and gas prices will (i) stabilize,  (ii) increase, or (iii) decrease,
management believes it is unlikely that future oil and gas prices will remain as
high as those experienced at December 31, 2000.

      Results of Operations

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

      Total oil and gas sales increased $126,587 (114.9%) in 2000 as compared to
1999.  Of this  increase,  approximately  $75,000  was related to an increase in
volumes of gas sold and approximately  $53,000 was related to an increase in the
average  price of gas sold.  Volumes of oil sold  decreased  180 barrels,  while
volumes  of gas sold  increased  37,161  Mcf in 2000 as  compared  to 1999.  The
increase  in volumes of gas sold was  primarily  due to  positive  prior  period
volume  adjustments made by the operators on two wells during 2000.  Average oil
and gas prices  increased to $35.24 per barrel and $2.61 per Mcf,  respectively,
in 2000 from $15.25 per barrel and $2.02 per Mcf, respectively, in 1999.

      Oil and gas production  expenses  (including lease operating  expenses and
production  taxes)  increased  $1,460  (5.1%) in 2000 as compared to 1999.  This
increase was primarily due to an increase in production  taxes  associated  with
the  increase in oil and gas sales,  which  increase was  partially  offset by a
negative prior period lease operating expense adjustment made by the operator on
one well during  2000.  As a  percentage  of oil and gas sales,  these  expenses
decreased  to 12.8 % in 2000 from 26.2% in 1999.  This  percentage  decrease was
primarily due to the increases in the average prices of oil and gas sold.

      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
decreased  $6,367  (45.2%)  in 2000 as  compared  to  1999.  This  decrease  was
primarily  due to increases  in the oil and gas prices used in the  valuation of
reserves at December 31, 2000 as compared to December 31, 1999,  which  decrease
was partially  offset by the increase in volumes of gas sold. As a percentage of
oil and gas sales,  this  expense  decreased to 3.3% in 2000 from 12.8% in 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  increased $9,883 (31.6%) in 2000 as
compared to 1999.  This  increase was  primarily  due to a change in  allocation
among the  Program  and other  affiliated  programs  of audit fees and  indirect
general and  administrative  expenses  reimbursed to the General  Partner.  As a
percentage of oil and gas sales, these expenses decreased to 17.4 % in 2000 from
28.4% in 1999. This percentage decrease was primarily due to the increase in oil
and gas sales.




                                      -16-
<PAGE>




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

      Total oil and gas sales  decreased  $37,043 (25.2%) in 1999 as compared to
1998.  Of this  decrease,  approximately  $42,000  was  related to a decrease in
volumes of gas sold.  This  decrease  was  partially  offset by an  increase  of
approximately  $5,000  related to an increase in the average  price of gas sold.
Volumes of oil and gas sold decreased 119 barrels and 21,975 Mcf,  respectively,
in 1999 as compared to 1998.  The decrease in volumes of gas sold was  primarily
due to (i) a positive prior period volume adjustment made by the operator on one
well during 1998 and (ii) the Program receiving a reduced percentage of sales on
three wells during 1999 due to the Program's overproduced gas balancing position
in those wells. These decreases were partially offset by a negative prior period
volume adjustment made by the purchaser on another well during 1998. Average oil
and gas prices  increased to $15.25 per barrel and $2.02 per Mcf,  respectively,
in 1999 from $10.92 per barrel and $1.92 per Mcf, respectively, in 1998.

      Oil and gas production  expenses  (including lease operating  expenses and
production  taxes)  decreased  $21,902 (43.1%) in 1999 as compared to 1998. This
decrease  was  primarily  due to (i) a  decrease  in  lease  operating  expenses
associated  with the  decreases in volumes of oil and gas sold and (ii) workover
expenses  incurred on one well  during 1998 in order to improve the  recovery of
reserves.  As a percentage  of oil and gas sales,  these  expenses  decreased to
26.2% in 1999 from 34.5% in 1998. This percentage  decrease was primarily due to
the dollar decrease in oil and gas production expenses.

      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
decreased  $4,633  (24.8%)  in 1999 as  compared  to  1998.  This  decrease  was
primarily  due to the  decreases in volumes of oil and gas sold. As a percentage
of oil and gas  sales,  this  expense  increased  to 12.8% in 1999 from 12.7% in
1998.

      General and administrative  expenses remained  relatively constant in 1999
as  compared  to 1998.  As a  percentage  of oil and gas sales,  these  expenses
increased  to 28.4% in 1999 from 21.4% in 1998.  This  percentage  increase  was
primarily due to the decrease in oil and gas sales.


      Liquidity and Capital Resources

     Net  proceeds  from  operations  less  necessary   operating   capital  are
distributed to the limited  partners on a quarterly  basis.  See "Item 5. Market
for the  Registrant's  Limited  Partnership  Units and Related  Limited  Partner
Matters."  The net proceeds  from  production  are not  reinvested in productive
assets,



                                      -17-
<PAGE>



except to the extent that  producing  wells are  improved,  or where methods are
employed to permit more efficient  recovery of reserves,  thereby resulting in a
positive economic impact.  Assuming 2000 production levels for future years, the
Program's proved reserve  quantities at December 31, 2000 would have a remaining
life of approximately 3.9 years for gas reserves and 9.1 years for oil reserves.
These life of reserves estimates are based on the current estimates of remaining
oil and gas reserves. See "Item 2. Properties" for a discussion of these reserve
estimates.  Any  decrease  from the high oil and gas prices at December 31, 2000
may cause a decrease in the estimated life of said reserves.

      The Program's  available capital from the limited partners'  subscriptions
has been spent on oil and gas drilling activities and there should be no further
material capital resource commitments in the future.  Occasional expenditures by
the Program for well completions or workovers,  however, may reduce or eliminate
cash available for a particular  quarterly cash  distribution.  During 1999, the
Program  invested  $24,413 for the purchase of additional  gas reserves  (20,414
Mcf) in the Pankey Unit No. 1 well,  the Walter No. 1-24 well, and the Music No.
3-24 well in which the Program  owns  working  interests  of 6.77%,  7.41%,  and
1.70%,  respectively.  These  reserves  were  purchased  in order to assist  the
Program in reducing its gas imbalance  liabilities  on these wells.  The Program
has no debt  commitments.  Cash for  operational  purposes  has  generally  been
provided by current oil and gas  production.  Management  believes that cash for
ordinary  operational purposes in the future will be provided by current oil and
gas production.

      There can be no  assurance as to the amount of the  Program's  future cash
distributions.   The  Program's  ability  to  make  cash  distributions  depends
primarily  upon the level of  available  cash flow  generated  by the  Program's
operating  activities,  which will be affected (either positively or negatively)
by many factors  beyond the control of the Program,  including  the price of and
demand for oil and gas and other market and economic conditions.  Even if prices
and costs remain  stable,  the amount of cash available for  distributions  will
decline  over  time (as the  volume  of  production  from  producing  properties

      Inflation and Changing Prices

      Prices obtained for oil and gas production  depend upon numerous  factors,
including the extent of domestic and foreign production, foreign imports of oil,
market  demand,  domestic  and  foreign  economic  conditions  in  general,  and
governmental  regulations  and tax laws.  The general  level of inflation in the
economy did not have a material effect on the operations of the

Program in 2000.  Oil and gas prices have  fluctuated  during  recent  years and
generally  have not  followed  the  same  pattern  as  inflation.  See  "Item 2.

                       REPORT OF INDEPENDENT ACCOUNTANTS



TO THE PARTNERS

DYCO OIL AND GAS PROGRAM 1978-1 LIMITED PARTNERSHIP

      In our opinion, the accompanying balance sheets and the related statements
of operations,  changes in partners'  capital and cash flows present fairly,  in
all material  respects,  the financial  position of the Dyco Oil and Gas Program
1978-1 Limited  Partnership,  a Minnesota limited  partnership,  at December 31,
2000 and 1999,  and the results of its operations and its cash flows for each of
the three years in the period  ended  December  31,  2000,  in  conformity  with
accounting principles generally accepted in the United States of America.  These
financial  statements are the  responsibility of the Program's  management;  our
responsibility  is to express an opinion on these financial  statements based on
our audits. We conducted our audits of these financial  statements in accordance
with  auditing  standards  generally  accepted in the United  States of America,
which require that we plan and perform the audit to obtain reasonable  assurance
about whether the financial  statements  are free of material  misstatement.  An
audit includes examining,  on a test basis,  evidence supporting the amounts and
disclosures in the financial  statements,  assessing the  accounting  principles
used and  significant  estimates made by management,  and evaluating the overall
financial  statement  presentation.   We  believe  that  our  audits  provide  a
reasonable basis for our opinion.

      Organization and Nature of Operations

            The  Dyco  Oil and  Gas  Program  1978-1  Limited  Partnership  (the
      "Program"), a Minnesota limited partnership, commenced operations on April
      1, 1978. Dyco Petroleum Corporation ("Dyco") is the General Partner of the
      Program.  Affiliates of Dyco owned 1,247 (51.9%) of the Program's Units at
      December 31, 2000.

            The Program's sole business is the development and production of oil
      and gas with a concentration  on gas.  Substantially  all of the Program's
      gas reserves are being sold  regionally  in the "spot  market." Due to the
      highly  competitive  nature of the spot market,  prices on the spot market
      are  subject  to wide  seasonal  and  regional  pricing  fluctuations.  In
      addition,  such spot market sales are  generally  short-term in nature and
      are  dependent  upon  obtaining   transportation   services   provided  by
      pipelines.  The prices  received for the Program's oil and gas are subject
      to influences such as global consumption and supply trends.


      Cash and Cash Equivalents

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


      Credit Risk

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


      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.  Capitalized  costs are  depleted on a gross  revenue  method
      using estimates of proved reserves.  The full cost amortization  rates per
      equivalent Mcf of gas produced



                                      -26-
<PAGE>



      during the years ended  December 31,  2000,  1999,  and 1998,  were $0.09,
      $0.26, and $0.24, respectively. 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
      ("SEC"))  the excess is charged to expense in the year  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.


      Deferred Charge

            The Deferred Charge at December 31, 2000 and 1999  represents  costs
      deferred for lease  operating  expenses  incurred in  connection  with the
      Program's  underproduced  gas  imbalance  positions.   The  rate  used  in
      calculating  the deferred  charge is the average of the annual  production
      costs per Mcf. At December 31, 2000,  cumulative  total gas sales  volumes
      for  underproduced  wells were less than the Program's  pro-rata  share of
      total gas  production  on these wells by 8,526 Mcf,  resulting  in prepaid
      lease operating expenses of $2,739. At December 31, 1999, cumulative total
      gas sales  volumes for  underproduced  wells were less than the  Program's
      pro-rata  share of total gas  production  on these  wells by  32,182  Mcf,
      resulting in prepaid lease operating expenses of $11,701.


      Payable to General Partner

            The Payable to General  Partner at December 31, 1999  represents  an
      operating  advance  from the  General  Partner.  Such amount was repaid in
      January 2000.


      Accrued Liability

            The  Accrued  Liability  at December  31,  2000 and 1999  represents
      charges accrued for lease operating  expenses  incurred in connection with
      the  Program's  overproduced  gas  imbalance  positions.  The rate used in
      calculating the accrued  liability is the average of the annual production
      costs per Mcf. At December 31, 2000,  cumulative  total gas sales  volumes
      for overproduced  wells exceeded the Program's pro-rata share of total gas
      production  on these  wells by 73,408  Mcf,  resulting  in  accrued  lease
      operating expenses of $23,586. At December 31, 1999,  cumulative total gas
      sales



                                      -27-
<PAGE>



      volumes for  overproduced  wells exceeded the Program's  pro-rata share of
      total gas  production  on these wells by 75,863 Mcf,  resulting in accrued
      lease operating expenses of $27,584.


      Oil and Gas Sales and Gas Imbalance Payable

            The Program's oil and condensate  production is sold,  title passed,
      and revenue  recognized  at or near the Program's  wells under  short-term
      purchase  contracts at prevailing  prices in accordance with  arrangements
      which are  customary in the oil industry.  Sales of gas  applicable to the
      Program's interest in producing oil and gas leases are recorded as revenue
      when the gas is metered  and title  transferred  pursuant to the gas sales
      contracts  covering the Program's  interest in gas  reserves.  During such
      times as the  Program's  sales of gas exceed its pro rata  ownership  in a
      well,  such sales are recorded as revenue unless total sales from the well
      have  exceeded  the  Program's  share  of  estimated  total  gas  reserves
      underlying  the  property  at which  time  such  excess is  recorded  as a
      liability. The rates per Mcf used to calculate this liability are based on
      the  average  gas  prices  received  for  the  volumes  at  the  time  the
      overproduction  occurred.  No such  liability was recorded at December 31,
      2000 or December 31, 1999.


      Use of Estimates in Financial Statements

            The preparation of financial statements in conformity with generally
      accepted  accounting  principles requires management to make estimates and
      assumptions that affect the reported amounts of assets and liabilities and
      disclosure  of  contingent  assets  and  liabilities  at the  date  of the
      financial  statements  and the  reported  amounts of revenues and expenses
      during the  reporting  period.  Actual  results  could  differ  from those
      estimates.  Further,  the deferred charge, the accrued liability,  the gas
      imbalance payable, and the litigation contingency (see Note 4) all involve
      estimates which could materially differ from the actual amounts ultimately
      realized in the near term.  Oil and gas reserves (see Note 5) also involve
      significant  estimates  which  could  materially  differ  from the  actual
      amounts ultimately realized.


      Income Taxes

            Income or loss for income tax purposes is  includable  in the income
      tax returns of the partners. Accordingly, no recognition has been given to
      income taxes in the accompanying  financial statements.  During 1999, upon
      Samson Resources Company's ownership of Units first exceeding 50%



                                      -28-
<PAGE>



      and as required by IRS  Regulations,  the  Program's  tax year was changed
      from January 1/December 31 in order to coincide  with  Samson's tax year
      of July 1/June 30.


2.    TRANSACTIONS WITH RELATED PARTIES

            The Program  obtained an operating  advance from the General Partner
      during the fourth  quarter of 1999 due to the  purchase of reserves on one
      well. Such amount was repaid in January 2000.

            Under  the  terms of the  Program  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 years ended December 31, 2000, 1999, and 1998,
      such expenses  totaled $41,151,  $31,268,  and $31,524,  respectively,  of
      which $28,752, $24,876, and $24,876, respectively,  were paid each year 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,  together with
      any  compressor  rentals,  consulting,  or other services  provided.  Such
      charges are  comparable to third party charges in the area where the wells
      are located and are the same as charged to other working  interest  owners
      in the wells.


3.    MAJOR CUSTOMERS

            The following  purchaser  individually  accounted for 10% or more of
      the combined oil and gas sales of the Program for the years ended December
      31, 2000, 1999, and 1998:

            Purchaser                   2000       1999     1998
            ---------                   -----      -----    -----

              Marketing Company         94.9%      92.1%    96.3%

      In the event of interruption of purchases by this significant  customer or
      the  cessation  or  material   change  in   availability   of  open-access
      transportation  by the Program's  pipeline  transporters,  the Program may
      encounter  difficulty  in marketing  its gas and in  maintaining  historic
      sales levels.  Alternative  purchasers or transporters  may not be readily
      available.

4.    CONTINGENCY

            On February 13, 1998, a royalty  owner filed a lawsuit  against Dyco
      alleging  that Dyco amended or terminated  certain gas purchase  contracts
      and fraudulently concealed the settlement of these contracts.  The lawsuit
      involves  the Spurlin No.  1-23 Well.  Dyco has filed an Answer  asserting
      various  affirmative  defenses,  and  intends to  vigorously  defend  this
      lawsuit. A class  certification order was entered by the district court on
      February 25, 2000.  Dyco has filed an  interlocutory  appeal of this order
      which is currently  pending before the Oklahoma  Supreme Court.  As of the
      date of these financial  statements,  the Program is not able to determine
      the ultimate outcome of this lawsuit or the assessment of any damages that
      may result.


5.    SUPPLEMENTAL OIL AND GAS INFORMATION

            The  following  supplemental  information  regarding the oil and gas
      activities  of  the  Program  is  presented  pursuant  to  the  disclosure

      Costs Incurred

            The  Program  incurred  no oil and gas  property  exploration  costs
      during 2000,  1999, and 1998.  Costs incurred by the Program in connection
      with its oil and gas  property  acquisition  (purchase  of  reserves)  and
      development activities during 2000, 1999, and 1998, were as follows:

      Quantities of Proved Oil and Gas Reserves - Unaudited

            Set forth below is a summary of the changes in the net quantities of
      the  Program's  proved  crude oil and gas  reserves  for the  years  ended
      December 31, 2000,  1999,  and 1998.  Proved  reserves  were  estimated by
      petroleum  engineers  employed  by  affiliates  of Dyco.  Certain  reserve
      information  was reviewed by Ryder Scott  Company,  L.P.,  an  independent
      petroleum  engineering firm. All of the Program's  reserves are located in
      the  United  States.  The  following   information  includes  certain  gas
      balancing  adjustments  which  cause the gas  volumes  to differ  from the
      reserve information prepared by Dyco and reviewed by Ryder Scott.

            The process of estimating oil and gas reserves is complex, requiring
      significant   subjective   decisions  in  the   evaluation   of  available
      geological,  engineering,  and economic data for each reservoir.  The data
      for a given reservoir may change  substantially  over time as a result of,
      among other things,  additional development activity,  production history,
      and  viability  of   production   under   varying   economic   conditions;
      consequently,  it  is  reasonably  possible  that  material  revisions  to
      existing  reserve  estimates may occur in the near future.  Although every
      reasonable  effort  has been made to  ensure  that the  reserve  estimates
      reported  herein  represent the most  accurate  assessment  possible,  the
      significance  of  the  subjective  decisions  required  and  variances  in
      available data for various reservoirs make these estimates  generally less
      precise  than other  estimates  presented  in  connection  with  financial
      statement  disclosures.  The Program's  estimated remaining reserves as of
      December 31, 2000 were  determined  using oil and gas prices of $23.79 per
      barrel and $9.02 per Mcf, respectively.

directors,  or ten  percent  owners who were  delinquent  filers  during 2000 of
reports required under Section 16(a) of the Securities and Exchange Act of 1934.


ITEM 11.    EXECUTIVE COMPENSATION

      The Program is a limited  partnership and,  therefore,  has no officers or
directors.  The following  table  summarizes  the amounts paid by the Program as
compensation and  reimbursements  to Dyco and its affiliates for the three years
ended December 31, 2000:


             Compensation/Reimbursement to Dyco and its affiliates
                      Three Years Ended December 31, 2000

Type of Compensation/Reimbursement(1)                  Expense
-------------------------------------          -------------------------
                                                 2000       1999      1998
                                               --------    -------   -------
Compensation:
   Operations                                     (2)        (2)       (2)

Reimbursements:
   General and Administrative,
      Geological, and Engineering
      Expenses and Direct Expenses(3)          $28,752     $24,876   $24,876
----------

(1)   The  authority  for  all of such  compensation  and  reimbursement  is the
      Program Agreement.  With respect to the Operations activities noted in the
      table, management believes that such compensation is equal to or less than
      that  charged by  unaffiliated  persons in the same  geographic  areas and
      under the same conditions.
(2)   Affiliates  of the  Program  serve as  operator  of some of the  Program's
      wells.  Dyco,  as general  partner,  contracts  with such  affiliates  for
      services  as operator  of the wells.  As  operator,  such  affiliates  are
      compensated  at rates  provided in the operating  agreements in effect and
      charged to all parties to such agreement. The dollar amount of such



                                      -36-
<PAGE>



      compensation  paid by the  Program to such  affiliates  is  impossible  to
      quantify as of the date of this Annual Report.
(3)   The  Program  reimburses  Dyco  and  its  affiliates  for  reasonable  and
      necessary general and administrative, geological, and engineering expenses
      and direct  expenses  incurred in  connection  with their  management  and
      operation of the Program. The directors,  officers,  and employees of Dyco
      and its  affiliates  receive no direct  remuneration  from the Program for
      their services to the Program. See "Salary Reimbursement Table" below. The
      allocable general and administrative, geological, and engineering expenses
      are apportioned on a reasonable  basis between the Program's  business and
      all other oil and gas  activities  of Dyco and its  affiliates,  including
      Dyco's  management  and  operation  of  affiliated  oil  and  gas  limited
      partnerships. The allocation to the Program of these costs is made by Dyco
      as General Partner.

      As noted in the  Compensation/Reimbursement  Table above,  the  directors,
officers,  and  employees  of  Dyco  and  their  affiliates  receive  no  direct
remuneration  from the Program for their services.  However,  to the extent such
services  represent direct  involvement with the Program,  as opposed to general
corporate  functions,  such persons' salaries are allocated to and reimbursed by
the  Program.  Such  allocation  to the  Program's  general and  administrative,
geological, and engineering expenses of the salaries of directors, officers, and
employees of Dyco and its affiliates is based on internal records  maintained by
Dyco and its affiliates,  and represents investor relations,  legal, accounting,
data  processing,  management,  gas  marketing,  and  other  functions  directly
attributable  to the Program's  operations.  When actual costs incurred  benefit
other  partnerships  and  affiliates,  the  allocation  of costs is based on the
relationship  of the  Program's  reserves  to the  total  reserves  owned by all
partnerships and reserves.  The following table indicates the approximate amount
of general and administrative expense reimbursement attributable to the salaries
of the  directors,  officers,  and employees of Dyco and its  affiliates for the
three years ended December 31, 2000:

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


ITEM 12.    SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

      The following table provides information as to the beneficial ownership of
the Program's Units as of March 1, 2001 by each beneficial owner of more than 5%
of  the  issued  and  outstanding  Units  and by the  directors,  officers,  and
affiliates  of Dyco.  The address of each of such persons is Samson  Plaza,  Two
West Second Street, Tulsa, Oklahoma 74103.

Samson Resources Company                          1,247    (51.4%)

All directors, officers, and
   affiliates of Dyco as a group
   and Dyco (5 persons)                           1,247    (51.4%)


ITEM 13.    CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

      Certain affiliates of Dyco engage in oil and gas activities  independently
of the Program  which  result in  conflicts  of interest  that cannot be totally
eliminated.  The allocation of acquisition  and drilling  opportunities  and the
nature of the compensation  arrangements between the Program and such affiliates
also create potential conflicts of interest.  An affiliate of the Program owns a
significant  amount of the  Program's  Units and  therefore  has an  identity of
interest  with other  limited  partners  with respect to the  operations  of the
Program.

      In order to attempt to assure  limited  liability for limited  partners as
well as an orderly  conduct of business,  management of the Program is exercised
solely by Dyco. The Program Agreement grants Dyco broad discretionary  authority
with  respect  to  the  Program's   participation  in  drilling   prospects  and
expenditure and control of funds,  including  borrowings.  These  provisions are
similar to those contained in prospectuses and partnership  agreements for other
public oil and gas drilling partnerships.



                                      -39-
<PAGE>



Broad discretion as to general management of the Program involves  circumstances
where  Dyco has  conflicts  of  interest  and where it must  allocate  costs and
expenses, or opportunities, among the Program and other competing interests.

      Dyco does not devote all of its time, efforts,  and personnel  exclusively
to the  Program.  Furthermore,  the  Program  does not have any  employees,  but
instead relies on the personnel of Samson. The Program thus competes with Samson
(including  other  oil and gas  programs)  for the  time and  resources  of such
personnel.  Samson  devotes  such time and  personnel to the  management  of the
Program as are indicated by the  circumstances and as are consistent with Dyco's
fiduciary duties.

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

      Samson  Resources  Company,  an  affiliate  of  Dyco,  ("Resources")  owns
approximately 51% of the Program's outstanding Units as of March 1, 2001, making
the  Program a 50%  subsidiary  of  Resources.  The  Program  Agreement  permits
Resources to independently  vote its Units.  Resources'  majority Unit ownership
will  determine  the outcome of any matter  submitted  for a vote of the Limited
Partners.
