                                   (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,  1998  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.

                    NOTES TO FINANCIAL STATEMENTS (CONTINUED)
                                   (UNAUDITED)


     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 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 three  months  ended
        March 31, 1999 and 1998.

                  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
        interests in producing  oil and gas  properties.  Under the terms of the
        NP/OR Agreement, the Partnership has conveyed 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.

                                   (UNAUDITED)


(5)  Gas Imbalances -

                  The Partnership  recognizes its ownership  interest in natural
        gas  production as revenue.  Actual  production  quantities  sold may be
        different than the  Partnership's  ownership share in a given period. If
        the  Partnership's  sales exceed its ownership share of production,  the
        differences are recorded as deferred revenue. Gas balancing  receivables
        are  recorded  when the  Partnership's  ownership  share  of  production
        exceeds sales.

(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.

(8)  Year 2000 -

                  The  Year  2000  issue  results  from  computer  programs  and
        embedded computer chips with date fields that cannot distinguish between
        the years 1900 and 2000.  The  Managing  General  Partner  is  currently
        implementing  the steps necessary to make its operations and the related
        operations of the Partnership capable of addressing the Year 2000. These
        steps include 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.  By mid-1999,
        the Managing  General Partner expects the mission critical systems to be
        either replaced or updated and testing to be virtually completed.

                                   (UNAUDITED)


                  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 can be made by  upgrading  this
        software.  The Managing  General  Partner is currently in the process of
        either upgrading the off-the-shelf  software or receiving  certification
        as to Year 2000  compliance from vendors or third party  consultants.  A
        testing phase is being conducted as the software is updated or certified
        and is expected to be completed by mid-1999.

                  The  Managing  General  Partner  does not  believe  that costs
        incurred  to address  the Year 2000 issue with  respect to its  business
        systems  will 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
        is  projected  to be less  than  $150,000,  most of which  will be spent
        during  the  testing  phase.  The  Partnership's  share of this  cost is
        expected to be insignificant.

                  The  failure  to correct a material  Year 2000  problem  could
        result  in an  interruption,  or  failure  of  certain  normal  business
        activities or  operations.  Based on  activities  to date,  the Managing
        General  Partner  believes that it will be able to resolve any Year 2000
        problems  concerning  its financial and  administrative  systems.  It is
        undeterminable  how all the  aspects  of the Year 2000 will  impact  the
        Partnership.  The most  reasonably  likely  worst  case  scenario  would
        involve 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 be prone to Year  2000  problems  that  could not be  assessed  or
        detected by the Managing General  Partner.  The Managing General Partner
        is contacting  its major  purchasers,  customers,  suppliers,  financial
        institutions  and others  with whom it conducts  business  to  determine
        whether  they will be able to resolve  in a timely  manner any Year 2000
        problems directly  affecting the Managing General Partner or Partnership
        and to inform them of the Managing General Partner's internal assessment
        of its Year 2000  review.  There  can be no  assurance  that such  third
        parties will not fail to appropriately address their Year 2000 issues or
        will not  themselves  suffer a Year 2000  disruption  that  could have a
        material  adverse  effect  on the  Partnership's  activities,  financial
        condition  or  operating  results.  Based upon these  responses  and any
        problems  that arise  during the  testing  phase,  contingency  plans or
        back-up systems would be determined and addressed.

                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

      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  $27,873 and  $178,923 for the three
months ended March 31, 1999 and 1998, 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 $54,038 and $197,341 for the three months ended March 31, 1999 and 1998,
respectively.

      The  Partnership  does  not  allow  for  additional  assessments  from the
partners to fund capital requirements.  The Managing General Partner anticipates
that the  Partnership  will have adequate  liquidity from income from continuing
operations  to  satisfy  any  future  capital  expenditure  requirements.  Funds
generated  from  bank  borrowings  and  proceeds  from  the  sale of oil and gas
properties will be used to supplement this effort if deemed necessary.

RESULTS OF OPERATIONS

      Oil and gas sales  declined  $15,723 or 11 percent in the first quarter of
1999  when  compared  to the  corresponding  quarter  in  1998,  due  to  normal
production  decline from the  partnership's  wells.  Current quarter gas and oil
production  declined 12 percent and 16 percent,  respectively,  when compared to
first quarter 1998 production  volumes.  Gas prices increased 10 percent or $.17
to an average $1.84/MCF while oil prices remained flat at an average  $11.33/BBL
for the quarter.

      Corresponding  production costs per equivalent MCF decreased 19 percent in
the  first  quarter  of 1999  compared  to the  first  quarter  of 1998 as total
production costs decreased 31 percent.

                 CONDITION AND RESULTS OF OPERATIONS (CONTINUED)


      Total  depreciation  expense for the first  quarter of 1999  decreased  87
percent or  $316,589  when  compared to the first  quarter  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
depreciation  expense.  Normal  depreciation  expense  decreased  50  percent or
$47,538 in 1999  compared to first  quarter of 1998,  relating to the decline in
production volumes.

      The  Partnership   recorded  an  additional   provision  in  depreciation,
depletion and  amortization in the first quarter of 1998 for $269,051,  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.

      During 1999,  partnership  revenues  and costs will be shared  between the
Interest Holders and general partners in an 85:15 ratio.
