                          NOTES TO FINANCIAL STATEMENTS
                                   (UNAUDITED)


(1)  General Information -

                  The financial statements included herein have been prepared by
        the  Partnership  and are  unaudited  except  for the  balance  sheet at
        December  31,  1996  which has been  taken  from the  audited  financial
        statements at that date. The financial  statements reflect  adjustments,
        all of which  were of a  normal  recurring  nature,  which  are,  in the
        opinion  of  the  managing   general   partner   necessary  for  a  fair
        presentation.  Certain  information  and footnote  disclosures  normally
        included in financial  statements  prepared in accordance with generally
        accepted  accounting  principles have been omitted pursuant to the rules
        and regulations of the Securities and Exchange Commission  ("SEC").  The
        Partnership  believes adequate disclosure is provided by the information
        presented.  The financial  statements should be read in conjunction with
        the audited  financial  statements  and the notes included in the latest
        Form 10-K.

(2)  Organization and Terms of Partnership Agreement -

                  Swift Energy Pension  Partners  1993-D,  Ltd., a Texas limited
        partnership  ("the  Partnership"),  was formed on December 31, 1993, 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
        interest  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) 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 313 Interest Holders made total capital
        contributions of $3,280,356.

                  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.

(3)  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. Certain reclassifications have been
        made to prior year amounts to conform to the current year presentation.

                    NOTES TO FINANCIAL STATEMENTS (CONTINUED)
                                   (UNAUDITED)


      Nonoperating Interests in Oil and Gas Properties --

                  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 partners 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.

                  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  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  depreciation,  depletion and  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.

(4)  Related-Party Transactions -

                  The  Partnership  entered  into a Net Profits  and  Overriding
        Royalty  Interest  Agreement  ("NP/OR   Agreement")  with  Swift  Energy
        Operating Partners 1993-D, Ltd. ("Operating Partnership"), an affiliated
        partnership  managed  by Swift  for the  purpose  of  acquiring  working
        interests in producing  oil and gas  properties.  Under the terms of the
        NP/OR   Agreement,   the  Operating   Partnership  will  convey  to  the
        Partnership  nonoperating  interests in the aggregate net profits (i.e.,
        oil and gas  sales net of  related  operating  costs) of the  properties
        acquired equal to the Partnership's  proportionate share of the property
        acquisition costs.

(5)  Vulnerability Due to Certain Concentrations -

                  The  Company'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.

                  The Partnership extends credit 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.

                                   (UNAUDITED)


(6)  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.

                MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                       CONDITION AND RESULTS OF OPERATIONS


GENERAL

      The  Partnership  was formed for the purpose of investing in  nonoperating
interests in producing oil and gas  properties  located  within the  continental
United States and Canada.  In order to accomplish  this,  the  Partnership  goes
through two distinct yet  overlapping  phases with respect to its  liquidity and
results of  operations.  When the  Partnership  was  formed,  it  commenced  its
"acquisition"  phase,  with all funds  placed in  short-term  investments  until
required for the acquisition of nonoperating interests.  Therefore, the interest
earned on these pre-acquisition investments becomes the primary cash flow source
for  initial  Interest  Holder   distributions.   As  the  Partnership  acquires
nonoperating  interests  in  producing  properties,  net cash from  ownership of
nonoperating  interests  becomes  available  for  distribution,  along  with the
investment   income.   After  all  partnership   funds  have  been  expended  on
nonoperating  interests in producing  oil and gas  properties,  the  Partnership
enters its  "operations"  phase.  During  this phase,  income from  nonoperating
interests  in oil  and gas  sales  generates  substantially  all  revenues,  and
distributions  to Interest  Holders  reflect those  revenues less all associated
partnership expenses.  The Partnership may also derive proceeds from the sale of
nonoperating interests in acquired oil and gas properties, when the sale of such
interests is economically appropriate or preferable to continued operations.

LIQUIDITY AND CAPITAL RESOURCES

      The  Partnership  has expended all of the  Interest  Holders'  commitments
available  for  property  acquisitions  by acquiring  nonoperating  interests in
producing oil and gas properties.

      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.  The  Managing  General  Partner  believes  that the  funds  currently
available to the Partnership  will be adequate to meet any  anticipated  capital
requirements.

RESULTS OF OPERATIONS

      The  following  analysis  explains  changes  in the  revenue  and  expense
categories  for the quarter  ended  September  30, 1997  (current  quarter) when
compared to the quarter ended September 30, 1996  (corresponding  quarter),  and
for the nine months ended September 30, 1997 (current period),  when compared to
the nine months ended September 30, 1996 (corresponding period).

Three Months Ended September 30, 1997 and 1996

      Income  from  nonoperating  interests  decreased  4 percent in the current
quarter of 1997 when  compared to the third  quarter in 1996.  Oil and gas sales
declined $1,550 or a slight 1 percent in the third quarter of 1997 when compared
to the  corresponding  quarter in 1996,  primarily  due to decreased gas and oil
prices.  A decline  of 19 percent  or  $.49/MCF  in gas prices and 18 percent or
$3.65/BBL in oil prices had a  significant  impact on  partnership  performance.
Current  quarter  gas and oil  production  increased  18 percent and 22 percent,
respectively,  when  compared  to  third  quarter  1996  production,   partially
offsetting the effect of the decreased prices.

      Associated amortization expense increased 14 percent or $8,061.

      The  Partnership   recorded  an  additional   provision  in  depreciation,
depletion  and  amortization  in the third quarter of 1996 for $165,738 when the
present value,  discounted at ten percent, of estimated future net revenues from
oil and gas properties  based on the prices in effect at the filing date,  using
the  guidelines of the Securities  and Exchange  Commission,  was below the fair
market  value  originally  paid  for  oil  and gas  properties.  The  additional
provision  results from the Managing General  Partner's  determination  that the
fair market  value paid for  properties  may or may not  coincide  with  reserve
valuations  determined  according to guidelines of the  Securities  and Exchange
Commission.

                MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                       CONDITION AND RESULTS OF OPERATIONS


Nine Months Ended September 30, 1997 and 1996

      Income  from  nonoperating  interests  increased  9 percent in the current
period of 1997 when compared to the  corresponding  period in 1996.  Oil and gas
sales  increased  $33,477 or 8 percent in the first nine months of 1997 over the
corresponding  period in 1996. An increase of 17 percent in gas production was a
major contributing  factor to the increased  revenues for the period.  Decreased
oil production of 5 percent partially offset the gas production increases.

      Associated amortization expense increased 9 percent or $15,746.

      The  Partnership   recorded  an  additional   provision  in  depreciation,
depletion  and  amortization  in the first nine months of 1996 for $165,738 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  originally  paid for oil and gas
properties. The additional provision results from the Managing General Partner's
determination  that the fair  market  value paid for  properties  may or may not
coincide  with reserve  valuations  determined  according to  guidelines  of the
Securities and Exchange Commission.

      During 1997,  partnership  revenues  and costs will be shared  between the
Interest Holders and general partners in an 85:15 ratio.
