                          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,  1997  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.

     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
         statement.

                   SWIFT ENERGY PENSION PARTNERS 1993-D, LTD.
                    NOTES TO FINANCIAL STATEMENTS (CONTINUED)
                                   (UNAUDITED)


                  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.

                  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  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  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 the
        Partnership's proportionate share of the property acquisition costs.

(5)  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.

(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.

                   SWIFT ENERGY PENSION PARTNERS 1993-D, LTD.
                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  partner  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

      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.  Net cash
provided by  operating  activities  totaled  $198,554  and  $199,832 for the six
months ended June 30, 1998 and 1997, respectively.  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.  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.  Cash distributions
totaled  $119,633  and $155,294 for the six months ended June 30, 1998 and 1997,
respectively.

      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 June 30, 1998 (current  quarter) when compared
to the quarter  ended June 30,  1997  (corresponding  quarter),  and for the six
months ended June 30, 1998  (current  period),  when  compared to the six months
ended June 30, 1997 (corresponding period).

Three Months Ended June 30, 1998 and 1997

      Income  from  nonoperating  interests  decreased  48 percent in the second
quarter of 1998 when  compared  to the same  quarter in 1997.  Oil and gas sales
declined  $31,120 or 28 percent in the second  quarter of 1998 when  compared to
the  corresponding  quarter  in 1997,  primarily  due to  decreased  gas and oil
production.  Gas production  decreased 22 percent and oil production declined 18
percent.  The  decrease  in  production  volumes  had a  significant  impact  on
partnership performance. Also, current quarter oil prices declined 40 percent or
$6.68/BBL, further contributing to decreased revenues. Declines in revenues were
partially  offset by an increase  in gas prices of 11 percent or  $.19/MCF  when
compared to second quarter 1997 prices.

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


      Total  amortization  expense for the second  quarter of 1998 increased 201
percent or $117,393 when compared to the second quarter of 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 15 percent or $8,981
in the second  quarter  of 1998 when  compared  to the  second  quarter of 1997,
relating to the decrease in production volumes.

      The Partnership  recorded an additional  provision in amortization for the
second  quarter in 1998 of $126,374  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.

Six Months Ended June 30, 1998 and 1997

      Income from nonoperating  interests  decreased 58 percent in the first six
months  of 1998 when  compared  to the same  period  in 1997.  Oil and gas sales
declined $148,698 or 48 percent in the first six months of 1998 when compared to
the corresponding period in 1997, primarily due to decreased gas and oil prices.
A decline  in gas  prices of 24  percent  or  $.58/MCF  and in oil  prices of 43
percent or $8.00/BBL, had a significant impact on partnership performance. Also,
current  period  gas and oil  production  declined  29 percent  and 19  percent,
respectively,  when compared to the same period in 1997, further contributing to
decreased revenues.  Production declines are due to unanticipated depletion of a
producing zone in a South Louisiana well (Corexcal Acquisition).

      Total  amortization  expense for the first six months of 1998 increased 80
percent  or  $99,830  when  compared  to the  first  six  months  of  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  21  percent or
$26,544 in the first six months of 1998 when compared to the first six months of
1997, relating to the decrease in production volumes.

      The Partnership  recorded an additional  provision in amortization for the
first six months in 1998 of $126,374 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 1998,  partnership  revenues  and costs will be shared  between the
Interest Holders and general partners in an 85:15 ratio.
