ITEM 1.  BUSINESS

      General

      The Dyco Oil and Gas Program 1983-1 Limited Partnership (the "Program") is
a Minnesota  limited  partnership  engaged in the production of oil and gas. The
Program  commenced  operations  on July  1,  1983  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. 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 32  limited  partnerships,
including the Program.  Dyco is a wholly-owned  subsidiary of Samson  Investment
Company.  Samson  Investment  Company  and its various  corporate  subsidiaries,
including Dyco, (collectively,  the "Samson Companies") 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, 1997, the
Samson  Companies  owned  interests  in  approximately  13,000 oil and gas wells
located  in 19  states  of the  United  States  and  the  countries  of  Canada,
Venezuela,  and Russia.  At December 31,  1997,  the Samson  Companies  operated
approximately 2,500 oil and gas wells located in 15 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 the other  Samson
Companies.  As of March 1, 1998, the Samson Companies employed approximately 820
persons.  No employees  are covered by  collective  bargaining  agreements,  and
management believes that the Samson Companies provide 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


                                       3
<PAGE>



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.

      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


                                       4
<PAGE>



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  95.4% of the Program's oil and gas revenues  during the year
ended  December  31,  1997.  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  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.  The ability of the Program to produce and market oil
and gas profitably depends 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),  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 industry  trends
cannot be accurately predicted or anticipated.




                                       5
<PAGE>



      The most important variable affecting the Program's revenues is the prices
received  for  the  sale  of oil  and  gas.  Predicting  future  prices  is very
difficult.  Concerning  past trends,  average yearly  wellhead gas prices in the
United States have been volatile for a number of years.  For the past ten years,
such  average  prices have  generally  been in the $1.40 to $2.40 per Mcf range,
significantly  below prices  received in the early 1980s.  Average gas prices in
the latter part of 1996 and parts of 1997,  however,  were somewhat  higher than
those yearly  averages.  Gas prices are  currently in the middle  portion of the
10-year average price range described above.

      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 the  obtaining of  transportation  services  provided by
pipelines.  Spot prices for the Program's gas decreased from approximately $3.57
per Mcf at December  31,  1996 to  approximately  $2.32 per Mcf at December  31,
1997.  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.  Due to global  consumption and supply trends
over the last several  months,  as well as expectations of at least a short-term
slowdown in Asian energy  demand,  oil prices have  recently  been in the mid to
lower  portions of this  pricing  range,  and in early 1998 dropped to as low as
$12.00 per barrel. It is not known whether this trend will continue.  Prices for
the Program's oil decreased from approximately $23.75 per barrel at December 31,
1996 to approximately $16.25 per barrel at December 31, 1997.

      Future prices for both oil and gas will likely be different  from (and may
be lower  than) the prices in effect on  December  31,  1997.  Primarily  due to
heating  season  demand,  year-end  prices in many past years have  tended to be
higher, and in some cases  significantly  higher,  than the yearly average price
actually received by the Program for at least the following year.  Management is
unable to predict  whether  future oil and gas prices will (i)  stabilize,  (ii)
increase, or (iii) decrease.


      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  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


                                       6
<PAGE>



existing  insurance  coverage.  The  occurrence  of an event  which is not fully
covered  by  insurance  could have a material  adverse  effect on the  financial
position 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-K  ("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  for the year ended
December 31, 1997.

      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, 1997.  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").
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, 1997. Such prices were not escalated
except in  certain  circumstances  where  escalations  were  fixed  and  readily
determinable in accordance with applicable contract provisions.  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, 1997. Year-end prices have generally been
higher than prices during the rest of the year.  There can be no assurance  that
the prices used in  calculating  the net present value of the  Program's  proved
reserves at December 31, 1997 will actually be realized for such production.

      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, 1997

            Estimated proved reserves:
               Gas (Mcf)                              1,301,980
               Oil and liquids (Bbls)                     3,077

            Net present value
               (discounted at 10% per annum)         $1,258,075


      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 4 to the Program's financial statements, included in Item 8 of
this Annual Report.


      Significant Properties

      As of December 31, 1997,  the Program's  properties  consisted of 22 gross
(3.05 net) productive wells. The Program also owned a non-working interest in an
additional  3 wells.  Affiliates  of the  Program  operate 17 (68%) of its total
wells.  As of December 31, 1997, the Program had estimated total proved reserves
of  1,301,980  Mcf of gas  and  3,077  barrels  of  oil,  with a  present  value
(discounted  at 10% per annum) of estimated  future net cash flow of $1,258,075.
Substantially all of the Program's reserves are located in the Anadarko Basin of
western  Oklahoma and the Texas  panhandle,  which is an established oil and gas
producing  basin.  All of the Program's  properties  are located  onshore in the
continental United States.

      As of December 31, 1997,  the Program's  properties in the Anadarko  Basin
consisted  of 21 gross (2.72 net) wells.  The Program  also owned a  non-working
interest in an additional 3 wells. Affiliates of the Program operate 16 (67%) of
its total  Anadarko  Basin  wells.  As of  December  31,  1997,  the Program had
estimated total proved reserves in the Anadarko Basin of approximately 1,245,407
Mcf of gas and  approximately  3,077  barrels of crude oil, with a present value
(discounted at 10% per annum) of estimated future net cash flow of approximately
$1,219,081.


      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

      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 limited  partners during
1997.


                                   PART II

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 a Program.

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 most important  variable
affecting the Program's  revenues is the prices received for the sale of oil and
gas. Predicting future prices is very difficult. Concerning past trends, average
yearly  wellhead gas prices in the United States have been volatile for a number
of years. For the past ten years, such average prices have generally been in the
$1.40 to $2.40 per Mcf range,  significantly  below prices received in the early
1980s.  Average gas prices in the latter part of 1996 and parts of 1997 however,
were somewhat higher than those yearly averages. Gas prices are currently in the
middle portion of the 10-year average price range described above.

      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


                                       14
<PAGE>



spot market sales are generally  short-term in nature and are dependent upon the
obtaining of transportation services provided by pipelines.  Spot prices for the
Program's gas decreased from approximately $3.57 per Mcf at December 31, 1996 to
approximately  $2.32 per Mcf at December 31, 1997.  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.  Due to global  consumption and supply trends
over the last several  months as well as  expectations  of at least a short-term
slowdown in Asian energy  demand,  oil prices have  recently  been in the mid to
lower  portions of this  pricing  range,  and in early 1998 dropped to as low as
$12.00 per barrel. It is not known whether this trend will continue.  Prices for
the Program's oil decreased from approximately $23.75 per barrel at December 31,
1996 to approximately $16.25 per barrel at December 31, 1997.

      Future prices for both oil and gas will likely be different  from (and may
be lower  than) the prices in effect on  December  31,  1997.  Primarily  due to
heating  season  demand,  year-end  prices in many past years have  tended to be
higher, and in some cases  significantly  higher,  than the yearly average price
actually received by the Program for at least the following year.  Management is
unable to predict  whether  future oil and gas prices will (i)  stabilize,  (ii)
increase, or (iii) decrease.


      Results of Operations

                     Year Ended December 31, 1997 Compared
                        to Year Ended December 31, 1996
                     -------------------------------------

      Total oil and gas sales decreased  $547,893 (36.1%) in 1997 as compared to
1996. Of this decrease, approximately $3,000 and $659,000, respectively, related
to decreases in the volumes of oil and gas sold,  which  amounts were  partially
offset by an increase of  approximately  $116,000  related to an increase in the
average price of gas sold. Volumes of oil and gas sold decreased 161 barrels and
362,102 Mcf, respectively,  in 1997 as compared to 1996. The decrease in volumes
of gas sold  resulted  primarily  from (i) a  positive  prior  period  ownership
adjustment  made by the  operator in 1996 on one well which had reached  payout,
(ii)  normal  declines  in  production,  and  (iii)  a  negative  gas  balancing
adjustment  on one well in 1997.  Average  oil  prices  decreased  to $19.67 per
barrel in 1997 from $20.64 per barrel in 1996.  Average gas prices  increased to
$2.07 per Mcf in 1997 from $1.82 per Mcf in 1996.

      Oil and gas production  expenses  (including lease operating  expenses and
production taxes) decreased $42,029 (14.4%) in 1997


                                       15
<PAGE>



as compared to 1996.  This  decrease  resulted  primarily  from the  decrease in
volumes of oil and gas sold during 1997,  partially offset by workover  expenses
incurred on one well in 1997 in order to increase the recovery of reserves. As a
percentage of oil and gas sales these  expenses  increased to 25.7% in 1997 from
19.2% in 1996.  This  percentage  increase was  primarily  due to the higher gas
sales in 1996 caused by the prior period  ownership  adjustment and the workover
expenses discussed above.

      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
decreased  $18,490  (8.6%) in 1997 as compared to 1996.  This  decrease  was due
primarily to the decrease in volumes of oil and gas sold in 1997,  which amounts
were  partially  offset  by (i) a  decrease  in the price of oil and gas used to
value  reserves at December 31, 1997 and (ii) the increase in the average  price
of gas  sold  in  1997.  As a  percentage  of oil and gas  sales,  this  expense
increased  to 20.1% in 1997 from 14.1% in 1996.  This  percentage  increase  was
primarily  due to the  decrease  in the  prices  of oil  and gas  used to  value
reserves in 1997.

      General and  administrative  expenses  increased  $4,089 (4.5%) in 1997 as
compared to 1996. As a percentage of oil and gas sales, these expenses increased
to 9.8% in 1997 from 6.0% in 1996.  This  percentage  increase  was  primarily a
result of the decrease in oil and gas sales discussed above.


                     Year Ended December 31, 1996 Compared
                        to Year Ended December 31, 1995
                     -------------------------------------

      Total oil and gas sales increased  $921,912  (154.5%) for 1996 as compared
to 1995. Of this increase,  approximately  $408,000 and $512,000,  respectively,
were related to increases in the volumes and average price of gas sold.  Volumes
of oil sold decreased 52 barrels,  while volumes of gas sold  increased  340,246
Mcf for 1996 as compared to 1995.  The increase in volumes of gas sold  resulted
primarily from a positive prior period ownership adjustment made by the operator
during  1996  related to one well  which  reached  payout in June of 1993.  This
ownership  adjustment  resulted in gas sales of approximately  $382,974 (260,410
Mcf) during 1996  attributable to production in 1995,  1994, and the second half
of 1993. Average oil and gas prices increased to $20.64 per barrel and $1.82 per
Mcf,  respectively,  for  1996  from  $17.43  per  barrel  and  $1.20  per  Mcf,
respectively, for 1995.

      Oil and gas production  expenses  (including lease operating  expenses and
production  taxes)  increased  $7,100 (2.5%) for 1996 as compared to 1995.  This
increase resulted  primarily from an increase in production taxes resulting from
the  increase in gas sales  during 1996 as  compared to 1995,  which  amount was
partially offset by workover  expenses incurred during 1995 on one well in order
to improve the recovery of reserves. As a percentage of oil and gas sales, these
expenses decreased to 19.2% for 1996 from


                                       16
<PAGE>



47.6% for 1995. This percentage decrease was primarily a result of the increased
oil and gas sales discussed above.

      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
increased  $97,368 (83.5%) for 1996 as compared to 1995. This increase  resulted
primarily  from the  increase  in oil and gas sales  recognized  during  1996 as
compared to 1995. As a percentage of oil and gas sales,  this expense  decreased
to 14.1% for 1996 from 19.5% for 1995.  This  percentage  decrease was primarily
due to the increases in the average prices of oil and gas sold during 1996.

      General and administrative  expenses remained relatively constant for 1996
as  compared  to 1995.  As a  percentage  of oil and gas sales,  these  expenses
decreased  to 6.0% for 1996 from 15.5% for 1995.  This  percentage  decrease was
primarily due to the increases in oil and gas sales discussed above.


      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, 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  production levels for 1997, the Program's
proved  reserve  quantities at December 31, 1997 would have  remaining  lives of
approximately  2.8  years  for gas  reserves  and 6.4  years  for oil  reserves.
However,  since the Program's  reserve estimates are based on oil and gas prices
at December 31, 1997, it is possible that a significant  decrease in oil and gas
prices from  December  31, 1997  levels  will  reduce  such  reserves  and their
corresponding life-span.

      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.  The Program has no
debt commitments.  Cash for operational purposes 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


                                       17
<PAGE>



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
declines) since the Program is not replacing  production through acquisitions of
producing properties and drilling.


      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 1997.
Oil and gas prices have  fluctuated  during recent years and generally  have not

      Year 2000 Computer Issues

      Dyco has reviewed its  computer  systems and hardware to locate  potential
operational  problems  associated  with the year 2000. Such review will continue
until all potential  problems are located and  resolved.  Dyco believes that all
year-2000  problems  in its  computer  system have been or will be resolved in a
timely  manner and have not caused and will not cause either (i)  disruption  of
the Program's  operations or (ii) a material  effect on the Program's  financial
condition or results of operations.  However,  it is possible that the Program's
cash flows could be disrupted by year-2000 problems  experienced by operators of
the Program's wells, buyers of the Program's oil and gas, financial institutions
or other persons.  Dyco is unable to quantify the effect, if any, on the Program
of year-2000 computer problems which may be experienced by these third parties.

ITEM 8.  FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA



                       REPORT OF INDEPENDENT ACCOUNTANTS



TO THE PARTNERS

DYCO OIL AND GAS PROGRAM 1983-1 LIMITED PARTNERSHIP


      We have audited the  financial  statements of the Dyco Oil and Gas Program
1983-1 Limited  Partnership (a Minnesota limited  partnership) as listed in Item
14(a) of this Annual Report.  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 in accordance  with  generally  accepted  auditing
standards.  Those standards 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.  An audit also includes
assessing the  accounting  principles  used and  significant  estimates  made by
management,  as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.

      In our opinion, the financial statements referred to above present fairly,
in all material respects, the financial position of the Dyco Oil and Gas Program
1983-1 Limited Partnership at December 31, 1997 and 1996, and the results of its
operations  and cash  flows  for each of the  three  years in the  period  ended
December 31, 1997, in conformity with generally accepted accounting principles.

             For the Years Ended December 31, 1997, 1996, and 1995

1.    ORGANIZATION AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

      Organization and Nature of Operations

            The  Dyco  Oil and  Gas  Program  1983-1  Limited  Partnership  (the
      "Program"), a Minnesota limited partnership,  commenced operations on July
      1, 1983. Dyco Petroleum Corporation ("Dyco") is the General Partner of the
      Program.  Affiliates of Dyco owned 3,188 (41.5%) of the Program's Units at
      December 31, 1997.

            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 the obtaining of  transportation  services  provided by
      pipelines.


      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.  Subsequent
      to  year-end,  all oil and gas sales  accrued as of December 31, 1997 have
      been collected.


      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 composite gross revenue
      method using  estimates  of proved  reserves.  The full cost  amortization
      rates per equivalent  Mcf of gas produced  during the years ended December
      31, 1997, 1996, and 1995 were $0.42,


                                       24
<PAGE>



      $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.  In addition,  SEC rules  provide  that if prices  decline
      subsequent  to year end, any excess that  results from these  declines may
      also be charged to expense during the current year. 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, 1997 and 1996  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, 1997,  cumulative  total gas sales  volumes
      for  underproduced  wells were less than the Program's  pro-rata  share of
      total gas production from these wells by 80,632 Mcf,  resulting in prepaid
      lease  operating  expenses of $26,705.  At December 31,  1996,  cumulative
      total  gas  sales  volumes  for  underproduced  wells  were  less than the
      Program's  pro-rata  share of total gas  production  from  these  wells by
      114,293 Mcf, resulting in prepaid lease operating expenses of $31,202.


      Accrued Liability

            The  Accrued  Liability  at December  31,  1997 and 1996  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, 1997,  cumulative  total gas sales  volumes
      for overproduced  wells exceeded the Program's pro-rata share of total gas
      production  from these wells by 428,567 Mcf,  resulting  in accrued  lease
      operating expenses of $141,941. At December 31, 1996, cumulative total gas
      sales volumes for overproduced wells exceeded the Program's pro-rata share
      of total gas  production  from these wells by 461,827  Mcf,  resulting  in
      accrued lease operating expenses of $126,079.




                                       25

      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 income
      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 income  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.  At December 31, 1997,  total sales exceeded the
      Program's  share of  estimated  total gas reserves on two wells by $23,034
      (15,356  Mcf).  At December 31, 1996,  total sales  exceeded the Program's
      share of estimated  total gas  reserves on three wells by $57,521  (33,347
      Mcf). These amounts were recorded as gas imbalance  payables in accordance
      with the sales method.


      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 gas imbalance payable,  and
      the accrued  liability all involve estimates which could materially differ
      from the actual amounts ultimately  realized or incurred in the near term.
      Oil and gas reserves (see Note 4) 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.

2.    TRANSACTIONS WITH RELATED PARTIES

            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, 1997, 1996, and 1995,
      such expenses  totaled $94,713,  $90,624,  and $92,351,  respectively,  of
      which $71,280 was 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.

            During 1995 the Program sold gas at market  prices to El Paso Energy
      Marketing  Company,  formerly known as Premier Gas Company ("El Paso"). El
      Paso,  like other  similar gas  marketing  firms,  then resold such gas to
      third  parties at market  prices.  El Paso was an affiliate of the Program
      until December 6, 1995. During 1995, these sales totaled $584,600.


3.    MAJOR CUSTOMERS

            The following  purchaser  individually  accounted for 10% or more of
      the combined oil and gas revenues (excluding the gas imbalance adjustment)
      of the Program for the years ended December 31, 1997, 1996, and 1995:


            Purchaser         1997       1996     1995
            ---------         -----      -----    -----

            El Paso           95.4%      99.0%    98.0%

            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.    SUPPLEMENTAL OIL AND GAS INFORMATION

            The  following  supplemental  information  regarding the oil and gas
      activities  of  the  Program  is  presented  pursuant  to  the  disclosure
      requirements promulgated by the SEC.

      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, 1997,  1996,  and 1995.  Proved  reserves  were  estimated by
      petroleum  engineers  employed by affiliates of Dyco. 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.

            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 reserves were determined at December
      31,  1997 using oil and gas prices of $16.25 per barrel and $2.32 per Mcf,
      respectively.

     Judy K. Fox joined the Samson  Companies in 1990 and was named Secretary of
Dyco on June 30, 1996. Prior to joining the Samson Companies,  she served as Gas
Contract Manager for Ely Energy Company.  Ms. Fox is also Secretary of Berry Gas
Company,  Circle L Drilling  Company,  Compression,  Inc.,  Samson  Hydrocarbons
Company,  Samson Properties  Incorporated,  and Geodyne Resources,  Inc. and its
subsidiaries.


      Section 16(a) Beneficial Ownership Reporting Compliance

      To the best  knowledge  of the Program and Dyco,  there were no  officers,
directors,  or ten  percent  owners who were  delinquent  filers  during 1997 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, 1997:

             Compensation/Reimbursement to Dyco and its affiliates
                      Three Years Ended December 31, 1997

Type of Compensation/Reimbursement(1)                    Expense
-------------------------------------           -----------------------------
                                                 1997       1996       1995
                                                -------    -------    -------
Compensation:
   Operations                                     (2)        (2)        (2)
   Gas Marketing(3)                               (3)        (3)        (3)

Reimbursements:
   General and Administrative,
     Geological, and Engineering
     Expenses and Direct Expenses(4)            $71,280    $71,280    $71,280

----------

(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 a majority 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
      compensation  paid by the  Program to such  affiliates  is  impossible  to
      quantify as of the date of this Annual Report.
(3)   During 1995 El Paso, an affiliate of the Program  until  December 6, 1995,
      purchased a portion of the  Program's gas at market prices and resold such
      gas  at  market  prices  directly  to  end-users  and  local  distribution
      companies. During 1995, the Program sold $584,600 of gas to El Paso. After
      December  6,  1995,  the  Program's  gas  was  marketed  by  Dyco  and its
      affiliates,  who  were  reimbursed  for such  activities  as  general  and
      administrative expenses.
(4)   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


                                       32
<PAGE>



      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.  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, 1997:

      In addition to the  compensation/reimbursements  noted  above,  during the
three years ended December 31, 1997,  the Samson  Companies were in the business
of  supplying  field and  drilling  equipment  and  services to  affiliated  and
unaffiliated parties in the industry. Such companies may have provided equipment
and services for wells in which the Program has an interest. These equipment and
services were  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 February 28, 1998 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 Properties Incorporated                3,189       (41.5%)

      All directors, officers, and
         affiliates of Dyco as a group
         and Dyco (5 persons)                       3,189       (41.5%)


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


                                       35
<PAGE>



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
partnerships.  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 the Samson  Companies.  The  Program  thus
competes with the Samson Companies  (including other currently sponsored oil and
gas programs) for the time and resources of such personnel. The Samson Companies
devote 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 the
Samson Companies, 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 the Samson Companies. On the
other hand,  management  believes  that the Program's  negotiating  strength and
contractual  positions have been enhanced by virtue of its affiliation  with the
Samson Companies.

     For a description of certain other relationships and related  transactions,
see "Item 11. Executive Compensation."
