                          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)  Organization and Terms of Partnership Agreement -

                  Swift Energy Operating Partners 1993-B,  Ltd., a Texas limited
        partnership  (the  Partnership),  was formed on June 30,  1993,  for the
        purpose of  purchasing  and operating  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 606 Interest Holders made total capital
        contributions of $9,627,683.

                  Generally,  all continuing costs (including development costs,
        operating costs,  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.

     Oil and Gas Properties --

                  For financial  reporting purposes the Partnership  follows the
        "full-cost"  method of accounting for oil and gas property costs.  Under
        this  method of  accounting,  all  productive  and  nonproductive  costs
        incurred in the  acquisition and development of oil and gas reserves are
        capitalized.  Such costs  include  lease  acquisitions,  geological  and
        geophysical  services,  drilling,  completion,   equipment  and  certain
        general and  administrative  costs directly  associated with acquisition
        and development activities.  General and administrative costs related to
        production and general overhead are expensed as incurred. No general and
        administrative  costs  were  capitalized  during the nine  months  ended
        September 30, 1996 and 1995.

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

                  Future  development,   site  restoration,   dismantlement  and
        abandonment   costs,   net  of  salvage  values,   are  estimated  on  a
        property-by-property  basis based on current economic conditions and are
        amortized  to  expense  as the  Partnership's  capitalized  oil  and gas
        property costs are amortized.

                  The  unamortized  cost of 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 proved properties using current prices,  discounted at ten
        percent,  and the lower of cost or fair  value of  unproved  properties.
        Proceeds  from the sale or  disposition  of oil and gas  properties  are
        treated as a reduction  of oil and gas  property  costs with no gains or
        losses being recognized except in significant transactions.

                  The  Partnership  computes  the  provision  for  depreciation,
        depletion   and   amortization   of  oil  and  gas   properties  on  the
        units-of-production   method.   Under  this  method,  the  provision  is
        calculated  by  multiplying  the total  unamortized  cost of oil and gas
        properties,    including   future    development,    site   restoration,
        dismantlement  and abandonment  costs, by an overall  amortization  rate
        that  is  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 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 -

                  Effective  June 30, 1993, the  Partnership  entered into a Net
        Profits and Overriding  Royalty Interest  Agreement ("NP/OR  Agreement")
        with Swift Energy Pension Partners 1993-B,  Ltd. (Pension  Partnership),
        an affiliated  partnership managed by Swift for the purpose of acquiring
        nonoperating  interests in producing oil and gas  properties.  Under the
        terms of the NP/OR Agreement, the Partnership will convey to the Pension
        Partnership 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 Pension  Partnership's  proportionate share of the
        property acquisition costs.

(5)  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.

(6)  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)


(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.

                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 and Canada. 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 Interest Holder  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 Interest Holders 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 expended all of the  Interest  Holders'  commitments
available  for  property   acquisitions  by  acquiring  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,  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 $23,824 or 6 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 80  percent  or
$1.29/MCF and in oil prices of 35 percent or $5.39/BBL had a significant  impact
on partnership performance.  Current quarter gas and oil production decreased 34
percent and 32  percent,  respectively,  when  compared  to third  quarter  1995
production  volumes,  partially  offsetting  the effect of increased gas and oil
prices.

      Associated depreciation expense decreased 17 percent or $30,338.

      The  Partnership   recorded  an  additional   provision  in  depreciation,
depletion  and  amortization  in the third quarter of 1996 and 1995 for $279,615
and $67,224, respectively, 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 (CONTINUED)


Nine Months Ended September 30, 1996 and 1995

      Oil and gas sales decreased $4,935 or a slight 1 percent in the first nine
months of 1996 over the corresponding period in 1995. A decline of 34 percent in
gas production and 23 percent in oil production were major contributing  factors
to the  decreased  revenues  for the period.  Current  period gas and oil prices
decreased  62 percent or  $.95/MCF  and 20 percent or  $3.20/BBL,  respectively,
compared  to  the  corresponding   period  in  1995,  partially  offsetting  the
production declines.

      Associated depreciation expense decreased 19 percent or $109,087.

      The  Partnership   recorded  an  additional   provision  in  depreciation,
depletion  and  amortization  in the  first  nine  months  of 1996  and 1995 for
$279,615 and $77,708,  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 and Exchange Commission.

      During 1996,  partnership  revenues  and costs will be shared  between the
Interest Holders and general partners in an 85:15 ratio.
