                    SWIFT ENERGY INCOME PARTNERS 1987-D, LTD.
                          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,  1995  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)  Gas Imbalances -

                  The  gas  imbalance   receivable  and  deferred  revenues  are
        accounted  for on  the  entitlements  method,  whereby  the  Partnership
        records its share of revenue,  based on its entitled amount. Any amounts
        over or under  the  entitled  amount  are  recorded  as an  increase  or
        decrease  to the  gas  imbalance  receivable  or  deferred  revenues  as
        applicable.

(3)  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.

(4)  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 INCOME PARTNERS 1987-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 producing oil
and gas properties  located within the  continental  United States.  In order to
accomplish  this,  the  Partnership  goes through two  distinct yet  overlapping
phases  with  respect  to its  liquidity  and  result  of  operations.  When the
Partnership  is formed,  it commences its  "acquisition"  phase,  with all funds
placed in short-term  investments until required for such property acquisitions.
The interest  earned on these  pre-acquisition  investments  becomes the primary
cash flow source for initial partner distributions.  As the Partnership acquires
producing   properties,   net  cash  from  operations   becomes   available  for
distribution,  along with the investment  income.  After  partnership funds have
been expended on producing oil and gas properties,  the  Partnership  enters its
"operations" phase. During this phase, oil and gas sales generate  substantially
all revenues,  and  distributions  to partners  reflect those  revenues less all
associated  partnership expenses.  The Partnership may also derive proceeds from
the sale of acquired oil and gas properties, when the sale of such properties is
economically appropriate or preferable to continued operation.

LIQUIDITY AND CAPITAL RESOURCES

      The  Partnership  has  completed  acquisition  of  producing  oil  and gas
properties,  expending  all  of  limited  partners'  commitments  available  for
property acquisitions.

      The  Partnership  does  not  allow  for  additional  assessments  from the
partners  to fund  capital  requirements.  However,  funds  in  addition  to the
remaining  unexpended net capital commitments of the partners are available from
partnership  revenues,  borrowings  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, 1996  (current  quarter) when
compared to the quarter ended September 30, 1995  (corresponding  quarter),  and
for the nine months ended September 30, 1996 (current period),  when compared to
the nine months ended September 30, 1995 (corresponding period).

Three Months Ended September 30, 1996 and 1995

      Oil and gas sales  increased  $55,991 or 26 percent in the current quarter
of 1996 when  compared to the  corresponding  quarter in 1995,  primarily due to
increased  gas and oil  prices.  An  increase  in gas  prices of 48  percent  or
$.80/MCF and in oil prices of 45 percent or $6.32/BBL had a  significant  impact
on partnership performance.  Current quarter oil and gas production decreased 29
percent and 39  percent,  respectively,  when  compared  to third  quarter  1995
production  volumes,  partially  offsetting  the  increased  revenues  from  the
increased gas and oil prices.

      Associated depreciation expense decreased 19 percent or $18,775.

      The  Partnership   recorded  an  additional   provision  in  depreciation,
depletion  and  amortization  in the third quarter of 1996 and 1995 for $122,229
and $48,421, respectively, 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 Exchange Commission.

                MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
                 CONDITION AND RESULTS OF OPERATIONS (CONTINUED)


Nine Months Ended September 30, 1996 and 1995

      Oil and gas sales  increased  $122,825  or 18  percent  in the first  nine
months of 1996 over the corresponding  period in 1995. An increase in gas prices
of 46 percent or  $.76/MCF  and in oil  prices of 23 percent or  $3.32/BBL  were
major  contributing  factors to the  increased  revenues  for the period.  Also,
current  period gas and oil  production  decreased  19 percent  and 25  percent,
respectively,  when  compared  to the  corresponding  period in 1995,  partially
offsetting the effect of increased gas and oil prices.

      Associated depreciation expense decreased 20 percent or $59,326.

      The  Partnership   recorded  an  additional   provision  in  depreciation,
depletion  and  amortization  in the  first  nine  months  of 1996  and 1995 for
$122,229 and $48,421,  respectively,  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 Exchange Commission.

      During 1996,  partnership  revenues  and costs will be shared  between the
limited partners and general partners in a 90:10 ratio.
