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 31  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, "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.

      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



                                      -4-
<PAGE>



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  93.1% of the Program's oil and gas revenues  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   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>



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  maintains  insurance  coverage  as is  customary  for
entities of a similar size engaged in operations similar to that of the Program,
but losses



                                      -6-
<PAGE>



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 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-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 during the year ended
December 31, 2000.

      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



                                      -9-
<PAGE>



estimates  generally less precise than other  estimates  presented in connection
with financial statement disclosures.

                              From Proved Reserves

                          As of December 31, 2000(1)

            Estimated proved reserves:
               Gas (Mcf)                                967,455
               Oil and liquids (Bbls)                     1,095

            Net present value
               (discounted at 10% per annum)         $3,906,015

--------------------
(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 4 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 17 gross
(2.39 net) productive wells. The Program also owns a non-working  interest in an
additional  3 wells.  Affiliates  of the  Program  operate 14 (70%) 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.

      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



                                      -10-

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
2000.


                                    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 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  $250,239 (54.2%) in 2000 as compared to
1999. This increase was primarily related to an increase in the average price of
gas sold.  Volumes of oil and gas sold  decreased  223  barrels  and 11,252 Mcf,
respectively,  in 2000 as compared to 1999. Average oil and gas prices increased
to $28.88 per barrel and $3.22 per Mcf,  respectively,  in 2000 from  $16.97 per
barrel and $1.97 per Mcf, respectively, in 1999.

      The Program sold three wells in 2000 for $100,787. These wells represented
approximately  4% of the Program's  total  reserves.  The proceeds from the sale
would  have  reduced  the net book value of the oil and gas  properties  by 39%,
significantly   altering  the   Program's   capitalized   cost/proved   reserves
relationship.  Accordingly,  capitalized  costs were reduced by approximately 4%
and a gain on sale of oil and gas properties of $90,019 was recognized.  No such
sales occurred during 1999.

      Oil and gas production  expenses  (including lease operating  expenses and
production  taxes)  decreased  $12,473 (8.4%) in 2000 as compared to 1999.  This
decrease  was  primarily  due to (i) a  decrease  in  lease  operating  expenses
associated with the decreases in volumes of oil and gas sold, (ii) a decrease in
compression  expenses  incurred on one well during 2000 as compared to 1999, and
(iii) the sale of three wells during 2000. These decreases were partially offset
by an increase in production  taxes  associated with the increase in oil and gas
sales. As a percentage of oil and gas sales,  these expenses  decreased to 19.1%
in 2000 from 32.1% 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  $39,776  (59.5%)  in 2000 as  compared  to 1999.  This  decrease  was
primarily  due to an increase in the gas price used in the valuation of reserves
at December 31, 2000 as compared to December 31,  1999.  As a percentage  of oil
and gas sales,  this expense  decreased to 3.8% in 2000 from 14.5% in 1999. This
percentage  decrease was primarily due to the dollar  decrease in  depreciation,
depletion,  and  amortization and the increases in the average prices of oil and
gas sold.

      General and  administrative  expenses decreased $14,748 (16.7%) in 2000 as
compared to 1999.  This  decrease was  primarily  due to a change in  allocation
among  the  Program  and other  affiliated  programs  of  indirect  general  and
administrative  expenses  reimbursed to the General Partner.  As a percentage of
oil and gas sales, these expenses decreased to 10.3% in 2000 from



                                      -16-
<PAGE>



19.1% in 1999. This percentage decrease was primarily due to the increase in oil
and gas sales.


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

      Total oil and gas sales decreased  $208,903 (31.1%) in 1999 as compared to
1998.  Of this  decrease,  approximately  $233,000  was related to a decrease in
volumes of gas sold.  This  decrease  was  partially  offset by an  increase  of
approximately  $22,000  related to an increase in the average price of gas sold.
Volumes of oil sold  increased 36 barrels,  while volumes of gas sold  decreased
124,108 Mcf in 1999 as compared to 1998. The decrease in volumes of gas sold was
primarily  due to the  curtailment  of sales during 1999 on two wells due to the
Program's  overproduced gas balancing  position in those wells.  Average oil and
gas prices  increased to $16.97 per barrel and $1.97 per Mcf,  respectively,  in
1999 from $12.87 per barrel and $1.88 per Mcf, respectively, in 1998.

      Oil and gas production  expenses  (including lease operating  expenses and
production  taxes)  decreased  $28,975 (16.3%) in 1999 as compared to 1998. This
decrease  was  primarily  due to (i) a  decrease  in  lease  operating  expenses
associated  with the  decrease  in  volumes  of gas  sold,  (ii) a  decrease  in
production  taxes  associated with the decrease in oil and gas sales,  and (iii)
workover  expenses  incurred  on two wells  during  1998 in order to improve the
recovery of reserves.  These decreases were partially  offset by new compression
expenses  incurred on one well in 1999.  As a  percentage  of oil and gas sales,
these expenses  increased to 32.1% in 1999 from 26.4% in 1998.  This  percentage
increase was primarily due to the 1999 compression expenses.

      Depreciation,  depletion,  and  amortization  of oil  and  gas  properties
decreased  $55,818  (45.5%)  in 1999 as  compared  to 1998.  This  decrease  was
primarily  due to (i) the  decrease in volumes of gas sold,  (ii) an increase in
the gas price used in the valuation of reserves at December 31, 1999,  and (iii)
an upward  revision in the  estimate of  remaining  gas reserves at December 31,
1999. As a percentage of oil and gas sales,  this expense  decreased to 14.5% in
1999 from 18.3% in 1998.  This  percentage  decrease  was  primarily  due to the
dollar decrease in depreciation, depletion, and amortization.

      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 19.1% in 1999 from 13.2% 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, 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
remaining  lives of  approximately  4.4 years for gas reserves and 6.8 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.  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 will be provided by current oil and gas production.

      The Program's  Statements  of Cash Flows for the years ended  December 31,
2000,  1999, and 1998 include  proceeds from the sale of oil and gas properties.
These proceeds were included in the Program's first cash distribution  following
receipt of the proceeds.  It is possible that the  Program's  future  repurchase
values  and the  amount or  likelihood  of future  cash  distributions  could be
reduced as a result of the disposition of these properties.

      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.  Properties - Oil and Gas
Production, Revenue, and Price History."



ITEM 7A.    QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET
            RISK.

      The Program does not hold any market risk sensitive instruments.

                       REPORT OF INDEPENDENT ACCOUNTANTS



TO THE PARTNERS

DYCO OIL AND GAS PROGRAM 1983-1 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
1983-1 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.

              DYCO OIL AND GAS PROGRAM 1983-1 LIMITED PARTNERSHIP
                         Notes to Financial Statements
             For the Years Ended December 31, 2000, 1999, and 1998

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 3,669 (48.3%) 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 composite gross revenue
      method using estimates of proved reserves. The full cost



                                      -25-
<PAGE>



      amortization  rates per  equivalent  Mcf of gas produced  during the years
      ended  December 31, 2000,  1999,  and 1998 were $0.12,  $0.29,  and $0.34,
      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 from these wells by 59,324 Mcf,  resulting in prepaid
      lease  operating  expenses of $22,923.  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  from  these  wells by
      67,779 Mcf, resulting in prepaid lease operating expenses of $24,035.


      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  from these wells by 306,108 Mcf,  resulting  in accrued  lease
      operating expenses of $118,280. At December 31, 1999, cumulative total gas
      sales volumes for overproduced wells exceeded the Program's pro-rata share
      of total gas  production  from these wells by 344,610  Mcf,  resulting  in
      accrued lease operating expenses of $122,199.

      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.  At December 31, 2000,  total sales exceeded the
      Program's  share of  estimated  total gas  reserves  on one well by $6,249
      (4,166  Mcf).  At December 31, 1999,  total sales  exceeded the  Program's
      share of estimated total gas reserves on one well by $20,865 (13,910 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, 2000, 1999, and 1998,
      such expenses  totaled $73,396,  $88,144,  and $88,278,  respectively,  of
      which $57,636, $71,280, and $71,280, 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  revenues  of the  Program  for the years ended
      December 31, 2000, 1999, and 1998:

      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

      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 reserves were determined at December
      31,  2000 using oil and gas prices of $23.75 per barrel and $8.46 per Mcf,
      respectively.

      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 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)            $57,636    $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



                                      -34-
<PAGE>



      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)   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  affiliates.  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.

      All directors, officers, and
         affiliates of Dyco as a group
         and Dyco (5 persons)                         3,670  (48.3%)


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



                                      -37-
<PAGE>



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 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.
