                                     PART I

Item 1.  Business

General Description of Partnership

          Swift  Energy  Pension   Partners   1994-D,   Ltd.,  a  Texas  limited
partnership (the  "Partnership" or the  "Registrant"),  is a partnership  formed
under a public serial limited partnership  offering denominated Swift Depositary
Interests  I  (Registration  Statement  No.  33-37983  on Form  S-1,  originally
declared  effective March 19, 1991, and amended  effective May 1, 1992, April 1,
1993,  April  19,  1994 and May 9,  1995 [the  "Registration  Statement"]).  The
Partnership was formed effective  December 30, 1994 under a Limited  Partnership
Agreement  dated  December  30,  1994.  The initial 256  investors  made capital
contributions of $3,032,126.  Investors in the Partnership hold Swift Depositary
Interests  ("SDIs")   representing   beneficial   ownership   interests  in  the
Partnership.

         The  Partnership  is  principally  engaged in the business of acquiring
nonoperating  interests  (i.e.,  net profits  interests,  royalty  interests and
overriding  royalty  interests)  in proven  oil and gas  properties  within  the
continental United States. The Partnership does not acquire working interests in
or operate oil and gas properties,  and does not engage in drilling  activities.
At December 31, 1999, the  Partnership  had expended or committed to expend 100%
of the Interest  Holders'  commitments  in the  acquisition  and  development of
nonoperating  interests in producing properties,  which properties are described
under Item 2, "Nonoperating  Interests in Properties,"  below. The Partnership's
income is  derived  almost  entirely  from its  nonoperating  interests  and the
disposition thereof.

         The  Partnership's  business and affairs are  conducted by its Managing
General  Partner,  Swift Energy  Company,  a Texas  corporation  ("Swift").  The
Partnership's Special General Partner, VJM Corporation, a California corporation
("VJM"), consults with and advises Swift as to certain financial matters.

         The  general  manner in which  the  Partnership  acquires  nonoperating
interests  and  otherwise  conducts  its  business is described in detail in the
Registration Statement under "Proposed Activities of the Partnerships," which is
incorporated herein by reference. The following is intended only as a summary of
the Partnership's manner of doing business and specific activities to date.

Liquidation

         In December 1999, the Managing General Partner mailed proxy material to
the  Interest  Holders  proposing  to sell  all the  Partnership's  nonoperating
interests in oil and gas properties and dissolve and liquidate the  Partnership.
During  the first  quarter of 2000,  the  Interest  Holders  of the  Partnership
approved the proposal to liquidate the Partnership. The Managing General Partner
anticipates  liquidation  will be  substantially  completed  within the next two
years.

Manner of  Acquiring  Nonoperating  Interests  in  Properties;  Net  Profits and
       Overriding Royalty Interest Agreement

         The nonoperating  interests owned by the Registrant have typically been
acquired  pursuant to a Net Profits and Overriding  Royalty  Interest  Agreement
dated December 31, 1994 (the "NP/OR Agreement") between the Registrant and Swift
Energy  Operating  Partners  1994-D,  Ltd. (the  "Operating  Partnership").  The
Operating  Partnership  is a Texas limited  partnership  that is also managed by
Swift and VJM.  The  Operating  Partnership  was formed to acquire  and  develop
producing oil and gas properties.

         Under the NP/OR Agreement, the Registrant and the Operating Partnership
have, in effect,  combined their funds to acquire  producing  properties.  Using
funds  committed to the NP/OR  Agreement  by both  partnerships,  the  Operating
Partnership  acquires producing  properties,  then promptly conveys nonoperating
interests therein to the Registrant. The Operating Partnership retains a working
interest in each such property, and is responsible for the production of oil and
gas therefrom. For the sake of legal and administrative  convenience,  producing
properties  are usually  acquired from the third party  sellers by Swift,  which
then  conveys  a  working  interest  in  each  such  property  to the  Operating
Partnership.  The Registrant  initially  committed  $3,032,126 and the Operating
Partnership  initially  committed  $4,775,604 for  acquisitions  under the NP/OR
Agreement.  The Operating  Partnership is obligated under the NP/OR Agreement to
convey to the  Registrant  a 39%  fixed  net  profits  interest  and a  variable
overriding  royalty  interest in specified  depths of all  producing  properties
acquired under the NP/OR Agreement.

                                      I-1

                   SWIFT ENERGY PENSION PARTNERS 1994-D, LTD.


         Under the NP/OR  Agreement,  the Operating  Partnership  is required to
convey  to  the  Registrant,   and  the  Registrant  is  required  to  purchase,
nonoperating  interests in all  producing  properties  acquired by the Operating
Partnership, except that:

                   1. properties anticipated to require significant  development
operations and nonoperating  interests  offered to the Operating  Partnership by
third  parties may be purchased by the Operating  Partnership  outside the NP/OR
Agreement, without participation by the Registrant;

                  2. during a  specified  one-year  period,  the  Registrant  is
entitled to reduce the amount originally  committed by it to purchases under the
NP/OR  Agreement  and to redirect  such funds to the  purchase  of  nonoperating
interests from sources other than the Operating Partnership; and

                  3. the  Registrant's  funds  will be  released  from the NP/OR
Agreement if they are not completely spent by the Operating Partnership within a
specified  period,  or if there is a prior  withdrawal of funds by the Operating
Partnership  to  purchase   properties   anticipated   to  require   significant
development.

         Purchases of nonoperating  interests by the Registrant  using withdrawn
or  released  funds  may be made  from  the  Managing  General  Partner  and its
affiliates,   other  partnerships  affiliated  with  the  Operating  Partnership
(possibly through the Registrant's  entry into a new NP/OR  Agreement),  or from
unaffiliated third parties.

         In accordance with its  obligations  under the NP/OR  Agreement,  as of
December 31, 1999,  the Operating  Partnership  had conveyed to the Registrant a
39% net profits interest  burdening  certain depths of all producing  properties
acquired  by the  Operating  Partnership  thereunder.  Typically,  a net profits
interest in an oil and gas property entitles the owner to a specified percentage
share of the gross proceeds generated by the burdened property, net of operating
costs.  The net  profits  interest  conveyed to the  Registrant  under the NP/OR
Agreement differs from the typical net profits interest in that it is calculated
over  the  entire  group  of  producing  properties  conveyed  under  the  NP/OR
Agreement; i.e., all operating costs attributable to the burdened depths of such
properties are  aggregated,  and the total is then  subtracted from the total of
all gross  proceeds  attributable  to such depths in order to calculate  the net
profits to which the Registrant is entitled.  The net profits interest  conveyed
to the Registrant  burdens only those depths of each subject property which were
evaluated to contain proved reserves at the date of  acquisition,  to the extent
such depths underlie specified surface acreage.

         The Operating Partnership has also conveyed to the Registrant under the
NP/OR  Agreement  an  overriding  royalty  interest  in each  property  acquired
thereunder. An overriding royalty interest is a fractional interest in the gross
production  (or the gross  proceeds  therefrom)  of oil and gas from a property,
free of any exploration,  development,  operation or maintenance expenses. Under
the NP/OR  Agreement,  the overriding  royalty  interest burdens the portions of
each producing  property that were  evaluated at the date of acquisition  not to
contain proved reserves.

Competition, Markets and Regulations

         Competition

         The oil and gas industry is highly  competitive in all its phases.  The
Partnership encounters strong competition from many other oil and gas producers,
many of which possess substantial financial resources, in acquiring economically
desirable Producing Properties.

         Markets

         The amounts of and price  obtainable  for oil and gas  production  from
Partnership  Properties will be affected by market factors beyond the control of
the  Partnership.  Such factors include the extent of domestic  production,  the
level of imports of foreign oil and gas, the general level of market demand on a
regional, national and worldwide basis, domestic and foreign economic conditions
that  determine  levels of industrial  production,  political  events in foreign
oil-producing  regions, and variations in governmental  regulations and tax laws
and  the  imposition  of new  governmental  requirements  upon  the  oil and gas
industry. There can be no assurance that oil and gas prices will not decrease in
the future, thereby decreasing net Revenues from Partnership Properties.

                                      I-2

<PAGE>

                   SWIFT ENERGY PENSION PARTNERS 1994-D, LTD.


         From time to time,  there may exist a  surplus  of  natural  gas or oil
supplies,  the effect of which may be to reduce the amount of hydrocarbons  that
the  Partnerships may produce and sell while such oversupply  exists.  In recent
years,  initial steps have been taken to provide  additional gas  transportation
lines from Canada to the United States. If additional Canadian gas is brought to
the United States market, it could create downward pressure on United States gas
prices.

         Regulations

         Environmental Regulation

         The federal  government  and various state and local  governments  have
adopted  laws and  regulations  regarding  the control of  contamination  of the
environment.  These laws and regulations may require the acquisition of a permit
by Operators before drilling commences,  prohibit drilling activities on certain
lands  lying  within  wilderness  areas or where  pollution  arises  and  impose
substantial  liabilities for pollution  resulting from operations,  particularly
operations near or in onshore and offshore waters or on submerged  lands.  These
laws and  regulations  may also  increase  the  costs of  routine  drilling  and
operation of wells.  Because these laws and regulations change  frequently,  the
costs to the  Partnership of compliance  with existing and future  environmental
regulations cannot be predicted.  However, the Managing Partner does not believe
that the  Partnership is affected in a significantly  different  manner by these
regulations than are its competitors in the oil and gas industry.

         Federal Regulation of Natural Gas

         The  transportation  and sale of natural gas in interstate  commerce is
heavily  regulated  by  agencies  of  the  federal  government.   The  following
discussion is intended only as a summary of the principal statutes,  regulations
and  orders  that  may  affect  the  production  and  sale of  natural  gas from
Partnership  Properties.  This  summary  should not be relied upon as a complete
review of applicable natural gas regulatory provisions.

         FERC Orders

         Several major  regulatory  changes have been implemented by the Federal
Energy Regulatory  Commission  ("FERC") from 1985 to the present that affect the
economics of natural gas production,  transportation and sales. In addition, the
FERC  continues  to  promulgate  revisions  to various  aspects of the rules and
regulations  affecting  those  segments of the natural gas industry  that remain
subject to the FERC's jurisdiction. In April 1992, the FERC issued Order No. 636
pertaining to pipeline restructuring. This rule requires interstate pipelines to
unbundle  transportation  and sales services by separately  stating the price of
each service and by providing  customers  only the particular  service  desired,
without  regard to the source for  purchase of the gas.  The rule also  requires
pipelines to (i) provide  nondiscriminatory  "no-notice"  service  allowing firm
commitment  shippers to receive  delivery of gas on demand up to certain  limits
without  penalties,  (ii) establish a basis for release and reallocation of firm
upstream  pipeline  capacity  and  (iii)  provide  non-discriminatory  access to
capacity by firm  transportation  shippers on a  downstream  pipeline.  The rule
requires interstate  pipelines to use a straight fixed variable rate design. The
rule imposes these same requirements upon storage facilities.

         FERC Order No. 500  affects the  transportation  and  marketability  of
natural gas.  Traditionally,  natural gas has been sold by producers to pipeline
companies,  which then  resold the gas to  end-users.  FERC Order No. 500 alters
this market structure by requiring  interstate  pipelines that transport gas for
others to provide  transportation  service to  producers,  distributors  and all
other shippers of natural gas on a nondiscriminatory, "first-come, first-served"
basis ("open access  transportation"),  so that producers and other shippers can
sell natural gas directly to end-users.  FERC Order No. 500 contains  additional
provisions intended to promote greater competition in natural gas markets.

         It is not anticipated  that the  marketability  of and price obtainable
for natural gas production from  Partnership  Properties  will be  significantly
affected  by FERC  Order No.  500.  Gas  produced  from  Partnership  Properties
normally  will be sold to  intermediaries  who have entered into  transportation
arrangements with pipeline companies.  These  intermediaries will accumulate gas
purchased from a number of producers and sell the gas to end-users  through open
access pipeline transportation.

         State Regulations

         Production  of any oil  and gas  from  Partnership  Properties  will be
affected  to some  degree  by  state  regulations.  Many  states  in  which  the
Partnership will operate have statutory provisions regulating the production and
sale  of oil  and  gas,  including  provisions  regarding  deliverability.  Such
statutes, and the regulations promulgated in connection therewith, are generally
intended to prevent  waste of oil and gas and to protect  correlative  rights to
produce  oil and  gas  between  owners  of a  common  reservoir.  Certain  state
regulatory  authorities  also  regulate  the amount of oil and gas  produced  by
assigning allowable rates of production to each well or proration unit.

         Federal Leases

         Some of the Partnership's properties are located on federal oil and gas
leases  administered by various federal  agencies,  including the Bureau of Land
Management.   Various  regulations  and  orders  affect  the  terms  of  leases,
exploration and development plans, methods of operation and related matters.

         Employees

         The  Partnership  has no  employees.  Swift,  however,  has a staff  of
geologists,   geophysicists,   petroleum  engineers,   landmen,  and  accounting
personnel who  administer  the  operations of Swift and the  Partnership.  As of
December 31, 1999, Swift had 173 employees.  Swift's administrative and overhead
expenses  attributable  to  the  Partnership's   operations  are  borne  by  the
Partnership.

Item 2.  Nonoperating Interests in Properties

         As of December  31, 1999,  the  Partnership  has acquired  nonoperating
interests in producing  oil and gas  properties  which are  generally  described
below.

Principal Oil and Gas Producing Properties

         The most  valuable  fields  in the  Partnership,  based  upon  year-end
engineering  estimates of discounted  future net revenues using constant pricing
and costs, are described below.

         1. The Chunchula Unit is located in Mobile County, Alabama, (Parker and
Parsley  acquisition)  and  produces  from  the  Smackover  horizon.  This  unit
represents 69% of this Partnership's value.

         2.  Approximately 27% of the Partnership's  value is from the AWP Field
in McMullen  County,  Texas  (Bracken  acquisition).  The wells produce from the
Olmos formation.

         The remaining  value in the  Partnership  is  attributable  to numerous
properties  none of which equals or exceeds 15 percent of the total  Partnership
value.

Title to Properties

         Title to substantially  all significant  producing  properties in which
the Partnership owns  nonoperating  interests has been examined.  In addition to
the nonoperating interests owned by the Partnership,  the properties are subject
to royalty,  overriding  royalty and other interests  customary in the industry.
The Managing  General  Partner does not believe any of these burdens  materially
detract from the value of the  properties  or will  materially  detract from the
value of the properties or materially  interfere with their use in the operation
of the business of the Partnership.

Production and Sales Price

         The following table  summarizes the sales volumes of the  Partnership's
net oil and gas production  expressed in MCFs.  Equivalent  MCFs are obtained by
converting oil to gas on the basis of their relative energy content;  one barrel
equals  6,000 cubic feet of gas.  Average Net  Nonoperating  Interest  Price per
Equivalent  MCF is  determined  by dividing the related oil and gas revenue from
nonoperating interests by the equivalent MCF's produced.

Net Proved Oil and Gas Reserves

         Presented below are the estimates of the Partnership's  proved reserves
as of December 31, 1999,  1998 and 1997. The  Partnership  does not itself own a
direct  interest in proved  reserves.  The proved reserve  estimates shown below
represent an estimate of the proved reserves owned by the Operating  Partnership
equal to the percentage net profits interest  conveyed to the Partnership by the
Operating Partnership. All of the Partnership's nonoperating interests in proved
reserves are located in the United States.

downward  variations  based on current  engineering  information  for production
rates,  volumetrics and reservoir  pressure.  Additionally,  changes in quantity
estimates  are the result of the  increase  or decrease in crude oil and natural
gas prices at each year end which have the effect of adding or  reducing  proved
reserves on marginal properties due to economic limitations.

</TABLE>

         There are numerous  uncertainties  inherent in estimating quantities of
proved  reserves and in projecting  the future rates of  production,  timing and
plan of  development.  Oil and gas reserve  engineering  must be recognized as a
subjective process of estimating  underground  accumulations of oil and gas that
cannot be measured  in an exact way,  and  estimates  of other  engineers  might
differ  from  those  above,  audited  by H. J.  Gruy and  Associates,  Inc.,  an
independent petroleum consulting firm. The accuracy of any reserve estimate is a
function of the quality of  available  data and of  engineering  and  geological
interpretation  and  judgment.  Results  of  drilling,  testing  and  production
subsequent  to the date of the estimate may justify  revision of such  estimate,
and, as a general rule,  reserve  estimates based upon  volumetric  analysis are
inherently  less  reliable  than  those  based on  lengthy  production  history.
Accordingly,  reserve  estimates are often  different from the quantities of oil
and gas that are ultimately recovered.

         In estimating  the oil and natural gas  reserves,  the  Registrant,  in
accordance with criteria  prescribed by the Securities and Exchange  Commission,
has used prices received as of December 31, 1999 without  escalation,  except in
those instances where fixed and determinable  gas price  escalations are covered
by  contracts,  limited  to the  price the  Partnership  reasonably  expects  to
receive.  The  Registrant  does not believe that any  favorable or adverse event
causing a significant  change in the estimated  quantity of proved  reserves has
occurred between December 31, 1999 and the date of this report.

         Future prices received for the sale of the  Partnership's  products may
be higher or lower than the prices used in the evaluation  described  above; the
operating  costs relating to such  production may also increase or decrease from
existing  levels.  The estimates  presented  above are in accordance  with rules
adopted by the Securities and Exchange Commission.

Item 3. Legal Proceedings

         The Partnership is not aware of any material pending legal  proceedings
to which it is a party or of which any of its property is the subject.

Item 4. Submission of Matters to a Vote of Security Holders

         No matters  were  submitted  to a vote of Interest  Holders  during the
fourth  quarter of the fiscal year covered by this  report,  except as discussed
above in Item 1. "Liquidation" section.

Item   5. Market Price of and Distributions on the Registrant's SDIs and Related
       Interest Holder Matters


Market Information

         SDIs in the  Partnership  were initially sold at a price of $1 per SDI.
SDIs are not traded on any exchange and there is no  established  public trading
market for the SDIs.

Holders

         As of December 31, 1999,  there were 255 Interest  Holders holding SDIs
in the Partnership.

Distributions

         The Partnership  generally makes distributions to Interest Holders on a
quarterly  basis,   subject  to  the  restrictions  set  forth  in  the  Limited
Partnership Agreement. In the fiscal years ended December 31, 1998 and 1999, the
Partnership  distributed  a total of  $223,600  and  $55,400,  respectively,  to
holders of its SDIs. Cash distributions constitute net proceeds from sale of oil
and  gas  production  after  payment  of  lease  operating  expenses  and  other
partnership expenses.  Some or all of such amounts or any proceeds from the sale
of partnership  properties  could be deemed to constitute a return of investors'
capital.

         Oil and gas  investments  involve a high risk of loss, and no assurance
can be given that any particular  level of  distributions to holders of SDIs can
be  achieved  or  maintained.   Although  it  is   anticipated   that  quarterly
distributions  will continue to be made through 2000, the Partnership's  ability
to make distributions  could be diminished by any event adversely  affecting the
oil and gas properties in which the Partnership  owns interests or the amount of
revenues received by the Partnership therefrom.

         The  Partnership's   Limited  Partnership  Agreement  contains  various
provisions  which might serve to delay,  defer or prevent a change in control of
the Partnership,  such as the requirement of a vote of Limited Partners in order
to  sell  all  or  substantially  all  of the  Partnership's  properties  or the
requirement of consent by the Managing  General  Partner to transfers of limited
partnership  interests  and  provisions  prohibiting  the  transfer  of  Limited
Partnership  Units  in any  fiscal  year in  excess  of a limit  which  has been
established in order to comply with certain federal income tax regulations.

Item   7.  Management's  Discussion  and  Analysis of  Financial  Condition  and
       Results of Operations

Liquidation

         In December 1999, the Managing General Partner mailed proxy material to
the  Interest  Holders  proposing  to sell  all the  Partnership's  nonoperating
interests in oil and gas properties and dissolve and liquidate the  Partnership.
During  the first  quarter of 2000,  the  Interest  Holders  of the  Partnership
approved the proposal to liquidate the Partnership. The Managing General Partner
anticipates  liquidation  will be  substantially  completed  within the next two
years.

Liquidity and Capital Resources

      Oil and gas reserves are depleting  assets and therefore often  experience
significant  production  declines each year from the date of acquisition through
the end of the life of the  property.  The primary  source of  liquidity  to the
Partnership comes almost entirely from the income generated from the sale of oil
and gas produced from ownership interests in oil and gas properties. This source
of  liquidity  and  the  related  results  of  operations,   and  in  turn  cash
distributions,  will decline in future  periods as the oil and gas produced from
these properties also declines while  production and general and  administrative
costs remain relatively stable making it unlikely that the Partnership will hold
the properties  until they are fully depleted,  but will likely liquidate when a
substantial  majority of the reserves have been produced.  Cash distributions to
partners  or  Interest  Holders  are  determined  quarterly,  based upon the net
profits interest payment received from the companion operating partnership, less
general  and  administrative  expenses.  The net  profits  interest  payment  is
determined  based upon net proceeds  from sale of oil and gas  production  after
payment of lease operating  expense,  taxes and development  costs. In addition,
future  partnership  cash  requirements  are taken  into  account  to  determine
necessary cash reserves.

      Net cash provided by (used in)  operating  activities  totaled  $(13,631),
$277,595 and $383,431 in 1999, 1998 and 1997,  respectively.  The use of cash in
1999 is related to the payment of development costs associated with the drilling
of two  undeveloped  locations  in  1998,  by the  companion  partnership.  Cash
provided by  proceeds  from the sale of  nonoperating  interests  in  properties
totaled  $135,690 in 1999.  Capital  expenditures in 1999, 1998 and 1997 totaled
$66,027,  $279,685 and $23,654,  respectively.  Cash  distributions  to partners
totaled $55,400, $243,285 and $418,888 in 1999, 1998 and 1997, respectively.  In
1999,  cash  distributions  were effected by the use of available  cash to repay
prior development  costs,  production  declines from the Partnership's  property
sales in 1999 and low oil and gas prices  received during the first part of this
year.

      The  Partnership  has  expended  all  of  the  partners'  net  commitments
available for property  acquisitions and development by acquiring  producing oil
and gas  properties.  The  partnership  invests  primarily  in proved  producing
properties  with nominal  levels of future costs of  development  for proven but
undeveloped reserves.  Significant purchases of additional reserves or extensive
drilling  activity  are not  anticipated.  The  Partnership  does not  allow for
additional  assessments  from the  partners or Interest  Holders to fund capital
requirements. However, funds are available from partnership revenues or proceeds
from the sale of partnership  property. As of December 31, 1999, the Partnership
anticipates  that its net profits  interest will be burdened with  approximately
$59,697, $46,432 and $9,302 over the next three years, respectively,  to develop
and enhance the proved oil and gas reserves related to its nonoperating property
interests.  The  Managing  General  Partner  believes  that the funds  currently
available to the Partnership  will be adequate to meet any  anticipated  capital

         Income from nonoperating interests remained flat in 1999 over 1998. Oil
and gas sales declined $32,968 or 10 percent in 1999 vs. 1998,  primarily due to
decreased  oil and gas  production.  In 1999,  production  volumes  decreased 26
percent  as  oil  and  gas  production  declined  35  percent  and  26  percent,
respectively,  when compared to 1998. Production declines were related to normal
depletion and the Partnership's  property sales. Oil prices increased 57 percent
or $5.61/BBL to an average of $15.50/BBL and gas prices  increased 14 percent or
$0.29/MCF  to an average of  $2.36/MCF  for 1999.  Increased  oil and gas prices
helped offset the effect of decreased production.

         Corresponding  production  costs per equivalent MCF increased 5 percent
in 1999 compared to 1998,  and total  production  costs  decreased 22 percent in
1999, due to production declines.

         Total amortization  expense for 1999 decreased 96 percent or $1,283,378
when compared to 1998. In 1998, two components, the normal provision, calculated
on the units of production method, and the additional provision, relating to the
ceiling  limitation,  make up total amortization  expense.  Normal  amortization
expense decreased 51 percent or $49,552 in 1999 compared to 1998, related to the
decline in production volumes.

         Income from  nonoperating  interests  decreased 55 percent in 1998 over
1997. Oil and gas sales  decreased 41 percent in 1998 vs. 1997. 1998 oil and gas
prices   decreased  43  percent  or  $7.48/BBL   and  26  percent  or  $.74/MCF,
respectively.  These price  declines  had a  significant  impact on  partnership
performance.  Also,  production volumes decreased 18 percent due to a 26 percent
gas production decrease and a 5 percent oil production decline.  The decrease in
production further contributed to the Partnership's decreased revenues.

         Total  amortization  expense for 1998 increased 114 percent or $710,750
when compared to 1997. Two components,  the normal provision,  calculated on the
units of  production  method,  and the  additional  provision,  relating  to the
ceiling  limitation,  make up total amortization  expense.  Normal  amortization
expense decreased 26 percent or $34,782 in 1998 when compared to 1997,  relating
to the 18 percent decrease in production volumes.

         The  Partnership  recorded an additional  provision in  amortization in
1998 and 1997 of $1,233,826 and $488,294,  when the present value, discounted at
ten percent, of estimated future net revenues from oil and gas properties, using
the  guidelines of the Securities  and Exchange  Commission,  was below the fair
market  value  for oil and  gas  properties  resulting  in a full  cost  ceiling
impairment.

         During 2000,  Partnership  revenues and costs are expected to be shared
between the Interest  Holders and general  partners in an 85:15 ratio.  Based on
current oil and gas prices,  anticipated  levels of oil and gas  production  and
expected  cash   distributions   during  2000,  the  Managing   General  Partner
anticipates that the Partnership sharing ratio will continue to be 85:15.

Year 2000

         The Year 2000  issue  resulted  from  computer  programs  and  embedded
computer  chips with date fields which could not  distinguish  between the years
1900 and 2000. The Managing General Partner  implemented steps necessary to make
its  operations  and  the  related  operations  of the  Partnership  capable  of
addressing the Year 2000. These steps included upgrading, testing and certifying
its  computer  systems and field  operation  services  and  obtaining  Year 2000
compliance  certification  from all important business  suppliers.  The Managing
General  Partner  formed a task force during 1998 to address the Year 2000 issue
and prepare its business systems for the Year 2000. The Managing General Partner
either replaced or updated mission critical systems and completed testing before
2000 began.

         The Managing  General  Partner's  business  systems are almost entirely
comprised of off-the-shelf  software.  Most of the necessary changes in computer
instructional  code were made by  upgrading  this  software.  In  addition,  the
Managing General Partner received  certification as to Year 2000 compliance from
vendors or third party consultants.

         The costs  incurred to address the Year 2000 issue with  respect to the
Managing  General  Partners'  business systems did not have a material effect on
the  Partnership's  results  of  operations,  or  its  liquidity  and  financial
condition.  The estimated total cost to the Managing  General Partner to address
Year 2000  issues  was less than  $150,000,  most of which was spent  during the
testing phase. The Partnership's share of this cost was insignificant.

         The most  reasonably  likely  worst  case  scenario  would  have been a
prolonged disruption of external power sources upon which core equipment relies,
resulting in a substantial  decrease in the Partnership's oil and gas production
activities.  In addition,  the pipeline  operators to whom the Managing  General
Partner  sells the  Partnership's  natural gas, as well as other  customers  and
suppliers,  could  have  been  prone to Year  2000  problems  that  could not be
assessed or detected by the Managing General Partner.

         As of the filing of this report,  the Managing  General  Partner is not
aware of any Year 2000 problems either  experienced by it or by parties which it
does business, and does not expect to experience such problems in the future.

                   SWIFT ENERGY PENSION PARTNERS 1994-D, LTD.

         From time to time, Swift as Managing General Partner of the Partnership
purchases Units in the  Partnership  from investors who offer the Units pursuant
to their right of  presentment,  which  purchases are made pursuant to terms set
out in the  Partnership's  original Limited  Partnership  Agreement.  Due to the
frequency  and  large  number  of  these   transactions,   Swift  reports  these
transactions  under  Section  16 of the  Securities  Exchange  Act of 1934 on an
annual  rather than a monthly  basis.  In some cases such annual  reporting  may
constitute a late filing of the required Section 16 reports under the applicable
Section 16 rules.

Item 11.  Executive Compensation

         As  noted  in  Item  10,  "Directors  and  Executive  Officers  of  the
Registrant,"  above,  the Partnership has no executive  officers.  The executive
officers of Swift and VJM are not compensated by the Partnership.

         Certain fees and  allowances  contemplated  by the Limited  Partnership
Agreement  were paid by the  Partnership to Swift and VJM. See Note (4) in Notes
To Financial Statements (Related-Party Transactions) for further discussion.

Item 12.  Security Ownership of Certain Beneficial Owners and Management

         No  single  Interest  Holder  is  known  to the  Partnership  to be the
beneficial owner of more than five percent of the Partnership's SDIs.

         Swift and VJM are not aware of any arrangement,  the operation of which
may at a subsequent date result in a change in control of the Partnership.

Item 13.  Certain Relationships and Related Transactions

         As  noted  in  Item  10,  "Directors  and  Executive  Officers  of  the
Registrant," above, the Partnership has no executive officers or directors,  and
thus has not  engaged  in any  transactions  in which  any  such  person  had an
interest.  The Partnership is permitted to engage in certain  transactions  with
Swift as Managing General Partner and VJM as Special General Partner, subject to
extensive  guidelines  and  restrictions  as  described  in  the  "Conflicts  of
Interest"  section of the Prospectus  contained in the  Registration  Statement,
which is incorporated herein by reference.

         Summarized  below are the  principal  transactions  that have  occurred
between the Partnership,  on one hand, and Swift, VJM and their  affiliates,  on
the other.

Certain Transactions with General Partners

         1.  As  described  in  Item  1,  "Business,"  above,  during  1994  the
Partnership  entered into an NP/OR  Agreement  with the  Operating  Partnership,
which is also managed by Swift and VJM.  Pursuant to such NP/OR  Agreement,  the
Operating Partnership acquired the oil and gas properties described under Item 2
above and conveyed nonoperating interests therein to the Partnership.

         2.  Swift  acts  as  operator  for  many  of the  wells  in  which  the
Partnership has  nonoperating  interests and has received  compensation for such
activities in accordance with standard industry operating agreements.

         3. The  Partnership  paid to Swift and VJM certain fees as contemplated
by the  Limited  Partnership  Agreement.  See Note  (4) in  Notes  To  Financial
Statements (Related-Party Transactions) for further discussion.

                    REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To Swift Energy Pension Partners 1994-D, Ltd.:

         We have audited the accompanying balance sheets of Swift Energy Pension
Partners 1994-D, Ltd., (a Texas limited partnership) as of December 31, 1999 and
1998, and the related statements of operations, partners' capital and cash flows
for the years ended December 31, 1999, 1998 and 1997. These financial statements
are  the  responsibility  of the  Managing  General  Partner's  management.  Our
responsibility  is to express an opinion on these financial  statements based on
our audits.

         We conducted our audits in accordance with auditing standards generally
accepted in the United States.  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 Swift Energy Pension
Partners  1994-D,  Ltd., as of December 31, 1999 and 1998 and the results of its
operations  and its cash flows for the years ended  December 31, 1999,  1998 and
1997, in conformity with accounting  principles generally accepted in the United
States.

                          NOTES TO FINANCIAL STATEMENTS

(1) Organization and Terms of Partnership Agreement -

         Swift Energy Pension Partners 1994-D, Ltd., a Texas limited partnership
("the  Partnership"),  was  formed on  December  30,  1994,  for the  purpose of
purchasing  net  profits  interest,  overriding  royalty  interests  and royalty
interests  (collectively,  "nonoperating  interests")  in producing  oil and gas
properties within the continental United States and Canada. Swift Energy Company
("Swift"),  a Texas  corporation,  and VJM  Corporation  ("VJM"),  a  California
corporation,  serve as Managing  General  Partner and Special General Partner of
the  Partnership,  respectively.  The sole limited partner of the Partnership is
Swift Depositary  Company,  which has assigned all of its beneficial (but not of
record)  rights  and  interests  as  limited  partner  to the  investors  in the
Partnership  ("Interest  Holders"),  in the form of Swift  Depositary  Interests
("SDIs").

         The  Managing  General  Partner  has  paid or  will  pay out of its own
corporate funds (as a capital contribution to the Partnership)  $507,881,  which
includes  all  selling  commissions,  offering  expenses,  printing,  legal  and
accounting  fees and other  formation  costs  incurred  in  connection  with the
offering of SDIs and the  formation of the  Partnership,  for which the Managing
General Partner will receive an interest in continuing costs and revenues of the
Partnership.  The 256  Interest  Holders  made total  capital  contributions  of
$3,032,126.

         Generally,  all continuing costs (including  general and administrative
reimbursements and direct expenses) and revenues are allocated 85 percent to the
Interest  Holders  and 15 percent to the  general  partners.  After  partnership
payout, as defined in the Partnership  Agreement,  continuing costs and revenues
will be shared 75 percent by the Interest Holders, and 25 percent by the general
partners. Payout had not occurred as of December 31, 1999.

         In December 1999, the Managing General Partner mailed proxy material to
the  Interest  Holders  proposing  to sell  all the  Partnership's  nonoperating
interests in oil and gas properties and dissolve and liquidate the  Partnership.
During  the first  quarter of 2000,  the  Interest  Holders  of the  Partnership
approved the proposal to liquidate the Partnership. The Managing General Partner
anticipates  liquidation  will be  substantially  completed  within the next two
years.

(2) Significant Accounting Policies -

Use of Estimates --

         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 at the
date of the  financial  statements  and the  reported  amounts of  revenues  and
expenses  during  the  reporting  period.   Actual  results  could  differ  from
estimates.

Oil and Gas Revenues --

         Oil and gas revenues are reported using the entitlement method in which
the  Partnership  recognizes  its interest in oil and natural gas  production as
revenue.

Nonoperating Interests in Oil and Gas Properties --

         The  Partnership  accounts  for its  ownership  interest in oil and gas
properties   using  the   proportionate   consolidation   method,   whereby  the
Partnership's share of assets, liabilities, revenues and expenses is included in
the appropriate classification in the financial statements.

         For  financial   reporting   purposes,   the  Partnership  follows  the
"full-cost"  method of  accounting  for  nonoperating  interests  in oil and gas
property  costs.  Under this  method of  accounting,  all costs  incurred in the
acquisition of nonoperating interests in oil and gas properties are capitalized.
The  unamortized  cost of  nonoperating  interests in oil and gas  properties is
limited to the "ceiling limitation", (calculated separately for the partnership,
limited partner,  and general partners).  The "ceiling limitation" is calculated
on a quarterly  basis and  represents  the  estimated  future net revenues  from
nonoperating interests in proved properties using current prices,  discounted at
ten percent.  Proceeds from the sale or disposition of nonoperating interests in
oil  and  gas  properties  are  treated  as a  reduction  of  the  cost  of  the
nonoperating  interests with no gains or losses recognized except in significant
transactions.

                                      IV-7

<PAGE>

                   SWIFT ENERGY PENSION PARTNERS 1994-D, LTD.
                    NOTES TO FINANCIAL STATEMENTS (CONTINUED)


         The Partnership computes the provision for amortization of nonoperating
interests in oil and gas  properties on the  units-of-production  method.  Under
this method,  the provision is calculated by multiplying  the total  unamortized
cost of  nonoperating  interests  in oil and gas  properties  by an overall rate
determined  by dividing  the physical  units of oil and gas produced  during the
period by the total estimated units of proved oil and gas reserves  attributable
to the Partnership's nonoperating interests at the beginning of the period.

         The  calculation  of the "ceiling  limitation"  and the  provision  for
amortization  is based on  estimates  of proved  reserves.  There  are  numerous
uncertainties  inherent  in  estimating  quantities  of proved  reserves  and in
projecting the future rates of production,  timing and plan of development.  The
accuracy of any reserve  estimate is a function of the quality of available data
and of  engineering  and  geological  interpretation  and  judgment.  Results of
drilling,  testing and  production  subsequent  to the date of the  estimate may
justify  revision of such  estimate.  Accordingly,  reserve  estimates are often
different from the quantities of oil and gas that are ultimately recovered.

Cash and Cash Equivalents --

         Highly liquid debt instruments with an initial maturity of three months
or less are considered to be cash equivalents.

Reclassifications --

         Certain  reclassifications have been made to the prior year balances to
conform with the current year presentation.

(3) Acquisition of Nonoperating Interests in Oil and Gas Property Costs -

         Effective December 31, 1994, the Partnership entered into a Net Profits
and Overriding Royalty Interests Agreement ("NP/OR Agreement") with Swift Energy
Operating Partners 1994-D, Ltd. ("Operating Partnership"), managed by Swift, for
the purpose of acquiring  interests in producing oil and gas  properties.  Under
the  terms  of  the  NP/OR  Agreement,  the  Partnership  has  been  conveyed  a
nonoperating  interest in the aggregate net profits (i.e., oil and gas sales net
of  related   operating   costs)  of  the  properties   acquired  equal  to  its
proportionate  share of the property  acquisition  costs,  as defined.  Property
acquisition costs are amounts actually paid by the Operating Partnership for the
properties  plus costs  incurred by the Operating  Partnership  in acquiring the
properties  and costs  related to screening and  evaluation  of  properties  not
acquired.  In  1999,  1998  and  1997,  the  Partnership  acquired  nonoperating
interests in producing oil and gas properties for $66,027, $279,685 and $23,654,
respectively.

         During  1998  and  1997,  the  Partnership's  unamortized  oil  and gas
property costs exceeded the quarterly  calculations of the "ceiling  limitation"
resulting  in  an  additional  provision  for  amortization  of  $1,233,826  and
$488,294,  respectively. In addition, during 1998 and 1997, the Interest Holders
share  of  unamortized  oil and  gas  property  costs  exceeded  their  "ceiling
limitation",  resulting  in a  valuation  allowance  of $990,013  and  $465,260,
respectively.  This amount is included in the income (loss)  attributable to the
Interest  Holders  shown in the statement of partners'  capital  together with a
"combining   adjustment"  for  the  difference  between  the  Interest  Holders'
valuation  allowance and the  Partnership's  full cost ceiling  write down.  The
"combining adjustment" changes quarterly as the Partnership's total amortization
provision is more or less than the combined amortization  provision attributable
to the general partners and Interest Holders.

(4) Related Party Transactions -

         During 1999, 1998 and 1997, the Partnership paid Swift $45,482 per year
as a general and administrative overhead allowance.

         During  1999,  1998  and  1997,  the  Partnership  also  paid  Swift an
incentive amount, as defined in the Partnership Agreement, for services rendered
to the  Partnership.  Such amounts totaled $926 in 1999, $621 in 1998 and $4,506
in 1997 and are included in general and administrative expenses.

(5) Federal Income Taxes -

         The Partnership is not a tax-paying entity. No provision is made in the
accounts of the Partnership for federal or state income taxes,  since such taxes
are liabilities of the individual partners,  and the amounts thereof depend upon
their respective tax situations.

                                      IV-8

<PAGE>

                   SWIFT ENERGY PENSION PARTNERS 1994-D, LTD.
                    NOTES TO FINANCIAL STATEMENTS (CONTINUED)


         The tax returns and the amount of distributable  Partnership income are
subject to  examination  by the federal  and state  taxing  authorities.  If the
Partnership's  royalty  income for federal  income tax  purposes  is  ultimately
changed by the taxing  authorities,  the tax  liability of the Interest  Holders
could be changed  accordingly.  Royalty  income  reported  on the  Partnership's
federal  return of income for the years ended  December 31, 1999,  1998 and 1997
was $40,646,  $0 and $288,970,  respectively.  The  difference  between  royalty
income for federal income tax purposes reported by the Partnership and income or
loss from  nonoperating  interests  reported herein  primarily  results from the
exclusion of amortization  (as described below) from ordinary income reported in
the Partnership's federal return of income.

(6) Vulnerability Due to Certain Concentrations -

         The Partnership's revenues are primarily the result of sales of its oil
and natural gas  production.  Market prices of oil and natural gas may fluctuate
and adversely affect operating results.

         In the normal  course of  business,  the  Partnership  extends  credit,
primarily  in the form of  monthly  oil and gas sales  receivables,  to  various
companies in the oil and gas industry which results in a concentration of credit
risk. This  concentration  of credit risk may be affected by changes in economic
or other conditions and may accordingly impact the Partnership's  overall credit
risk. However,  the Managing General Partner believes that the risk is mitigated
by the size,  reputation,  and nature of the companies to which the  Partnership
extends  credit.  In  addition,  the  Partnership  generally  does  not  require
collateral or other security to support customer receivables.

(7) Fair Value of Financial Instruments -

         The  Partnership's  financial  instruments  consist  of cash  and  cash
equivalents  and  short-term  receivables  and  payables.  The carrying  amounts
approximate  fair  value  due to the  highly  liquid  nature  of the  short-term
instruments.
