SWIFT ENERGY REPORTS FIRST QUARTER 2004 RESULTS:
- -----------------------------------------------

         RECORD REVENUES OF $65.4 MILLION;
         --------------------------------

         RECORD PRODUCTION OF 14.3 Bcfe; and
         -----------------------------------

         EARNINGS OF $0.52 PER SHARE
         ---------------------------

HOUSTON--(BUSINESS  WIRE)--May  5,  2004 -- Swift  Energy  Company  (NYSE:  SFY)
announced  today a 39%  increase in net income for the first  quarter of 2004 to
$14.6  million,  or $0.52 per diluted  share,  compared to $10.5  million in net
income before accounting  change, or $0.38 per diluted share earned in the first
quarter  of  2003.  Including  the  effect  of the SFAS  143  accounting  change
implemented in the first quarter of 2003, both net income and earnings per share
more than doubled from 2003 to 2004.

Production  increased  11% for the first  quarter of 2004 to 14.3 billion  cubic
feet  equivalent  ("Bcfe")  from the 12.9 Bcfe  produced in the first quarter of
2003 and  increased 7%  sequentially  from the 13.4 Bcfe  produced in the fourth
quarter of 2003.  The increases  were primarily due to higher levels of domestic
production at Lake  Washington  resulting  from Swift  Energy's two rig drilling
program in 2003, along with expanded  infrastructure in the field. First quarter
2004 production  included 10.4 Bcfe of domestic  production (a 35% increase) and
3.9 Bcfe  produced in New Zealand,  (a 25% decrease) in both cases when compared
to production in the same period in 2003.

Terry Swift,  President and CEO, noted,  "Swift Energy continues to successfully
implement its strategic plan.  Domestic  production  increases,  enhanced by the
current commodity  environment,  have delivered  excellent quarterly results. In
the Lake  Washington  area,  we will begin  acquiring  data from the 3-D seismic
shoot in the second  quarter.  This seismic data will lay the foundation for our
2005 drilling  program in this area. This new information  should add to Swift's
already substantial  inventory of identified  development  projects in this area
and exciting list of exploration prospects in New Zealand, which will enable the
Company to continue to fortify its strong  foundation and  accelerate  growth in
the coming years."

Revenues and Expenses

Total revenues for the first quarter of 2004 increased 22% to $65.4 million from
the $53.5  million of  revenues  in the first  quarter of 2003.  Swift  Energy's
increased  revenues for the quarter are attributable to both increased levels of
production and higher commodity prices.

Lease operating expenses,  before severance and ad valorem taxes, were $0.67 per
thousand  cubic  feet  equivalent  ("Mcfe")  in the first  quarter  of 2004,  an
increase  of 18%  compared to $0.57 per Mcfe in the first  quarter of 2003.  The
increase  was  predominately  due to the  facility  enhancement  costs  in  Lake
Washington,  along with higher currency  exchange rates and plant maintenance in
New Zealand.  General and administrative expenses were $0.28 per Mcfe during the
first quarter of both 2004 and 2003.  Depreciation,  depletion and  amortization
expense  was $1.28 per Mcfe in the first  quarter of 2004  compared to $1.16 per
Mcfe in the first  quarter  of 2003,  and  interest  expense  was $0.48 per Mcfe
compared to $0.52 per Mcfe for the 2003 period.  Also,  severance and ad valorem
taxes were up  appreciably  in the 2004  period to $0.44 per Mcfe from $0.36 per
Mcfe a year earlier due to higher  commodity  prices and  severance tax rates on
crude oil from our increased production in Louisiana.

Income tax expense in the first  quarter of 2004  includes a reduction  from the
U.S.  statutory  rate,  almost  entirely  the result of the  favorable  currency
exchange rate effect applied to New Zealand deferred taxes.

Production & Pricing

Domestically,  first quarter 2004 total production increased by 35% to 10.4 Bcfe
compared  with 7.7 Bcfe  produced in the first quarter of 2003 and increased 18%
sequentially compared to the 2003 fourth quarter production of 8.8 Bcfe. This is
a result of the  Company's  successful  drilling  efforts and  targeted  capital
expenditure program in the Lake Washington area.

New Zealand  accounted for 27% of total production with 3.9 Bcfe produced in the
first quarter of 2004. This 25% decrease from the 5.2 Bcfe produced in the first
quarter of 2003 and 16% decrease from fourth quarter 2003 production  levels was
in line with the Company's  guidance.  Production in New Zealand was expected to
be lower as increased use of  hydroelectricity in New Zealand has contributed to
a short-term  reduction in market demand, which is expected to continue at least
through the second quarter of this year.

In the first quarter of 2004,  Swift Energy realized an aggregate global average
price of $4.62 per Mcfe, an increase of 8% from first quarter 2003 price levels,
when the price averaged $4.26 per Mcfe.  Domestically,  the Company  realized an
aggregate  average  price of $5.24 per  Mcfe,  a  decrease  of 8% over the $5.68
received in the first quarter of 2003. In New Zealand,  the Company  received an
aggregate  average  price of $2.93 per Mcfe for the first  quarter  in 2004,  an
increase of 36% over the $2.15 per Mcfe realized in the same period of 2003.

Swift Energy realized  average domestic natural gas prices of $4.90 per thousand
cubic feet  ("Mcf") in the first  quarter  of 2004,  a decrease  of 19% from the
$6.03 per Mcf for the same period in 2003. Meanwhile, first quarter 2004 average
domestic  crude oil prices  increased  4% to $33.95 per barrel  from  $32.80 per
barrel  realized  in the same  period  of  2003.  Prices  for NGLs  domestically
averaged  $24.31  per barrel in the first  quarter,  a 15%  decrease  over first
quarter 2003 NGL prices of $28.47.

In New Zealand,  Swift Energy received an average natural gas price of $2.27 per
Mcf for the first quarter of 2004 under its long-term contracts,  a 40% increase
over the  $1.62  per Mcf  received  in the first  quarter  of 2003.  Also in New
Zealand,  the sales price of the Company's McKee blend crude oil averaged $36.03
per barrel,  an 11%  increase  over prices for the same period in 2003,  and the
Company's  NGL  contracts  yielded an average price of $16.00 per barrel for the
first  quarter of 2004.  New  Zealand  natural gas and NGL price  contracts  are
denominated in New Zealand dollars, which has continued to strengthen during the
first quarter 2004 against the U.S. dollar compared to the same period in 2003.

Domestic Operations

As previously  reported,  Swift Energy completed 12 of 14 wells  domestically in
the first quarter of 2004. Of these 14 wells, 12 were development  wells and two
were exploration  wells. In Lake Washington,  the Company completed six of seven
development  wells,  but was  unsuccessful  with an  exploration  well. In other
operated areas, Swift Energy completed a development well in the Austin Chalk in
the Masters Creek area, which has just been put on production and completed four
wells in the AWP Olmos area.  Swift also  completed an  exploration  well in its
South Texas drilling program, in the Guadalupe Pasture area in Willacy County.

Swift Energy has three  drilling rigs operating  domestically,  one drilling for
oil in the Lake  Washington  area and two  drilling  for  natural  gas in Texas,
including one non-operated rig.

New Zealand Operations

Swift Energy completed the Kauri-E3 and the Kauri-E4 wells in New Zealand during
the first quarter 2004. The recently  drilled Kauri-E4 well encountered both the
Kauri and Tariki  sands and was  perforated  in a 15-foot  section of the Tariki
sandstone,  at approximately  9,900 feet true vertical depth. The Tariki Sand in
this well is approximately 1,800 feet up-dip and over 3.5 miles from the initial
Tariki sand discovery in the Rimu-A1 well. The Kauri-E4 well was tested over two
days at various rates,  with the most recent rate of  approximately  4.0 million
cubic feet per day and 400 barrels per day of crude oil/condensate. The Kauri-E4
well is  currently  shut-in  gathering  pressure  data and is  expected to begin
sustained  production  testing  in the next few  weeks.  The  Kauri-E3  well was
completed in the Kauri Sand and plans to fracture stimulate the well are pending
while monitoring of the results of the Kauri-E4  production testing takes place.
The first well in the 2004 Manutahi Sand  drilling  program,  which is targeting
this shallow oil-bearing sand, will begin drilling later in May.

Borrowing Base

After a regular  semi-annual  review by its bank group, Swift Energy's borrowing
base was recently reaffirmed at $250 million effective May 1, 2004. The Company,
however, has continued to maintain the commitment amount at $150 million.  Under
the terms of its credit facility, the Company can increase the commitment amount
up to the total  amount of the  borrowing  base at its  discretion.  Price  Risk
Management

Swift  Energy  also  announced  that  since its last  update on April 19, it has
continued to enter into price risk management  transactions.  For June 2004, the
Company  executed a fixed price physical sale for crude oil of 1,500 barrels per
day at an average NYMEX strike price of $37.55 per barrel.  This NYMEX crude oil
strike  price  does not take into  account  transportation  charges or crude oil
quality  differentials  that could  result in  deductions  ranging from $2.00 to
$3.00 per barrel.  Also, the Company recently  purchased  additional natural gas
floors that cover 285,000  million British thermal units ("MMBtu") per month for
the third quarter of 2004, all at a strike price of $5.50 per MMBtu.  Details of
all of Swift  Energy's  price  risk  management  activities  can be found on the
Company's website.

(2)  See  reconciliation  on page  9.  Management  believes  that  the  non-GAAP
     measures  EBITDA and cash flow before  working  capital  changes are useful
     information  to  investors  because  they are widely  used by  professional
     research  analysts  in the  valuation,  comparison,  rating and  investment
     recommendations  of  companies  within  the  oil and  gas  exploration  and
     production  industry.  Many  investors use the published  research of these
     analysts in making their investment decisions.  EBITDA and cash flow before
     working capital  changes are widely accepted as financial  indicators of an
     oil and gas company's  ability to generate cash which is used to internally
     fund exploration and development activities and to service debt. EBITDA and
     cash flow before  working  capital  changes are not  measures of  financial
     performance  under GAAP and should not be considered as an  alternative  to
     cash  flows from  operating,  investing,  or  financing  activities,  as an
     indicator of cash flows, or as a measure of liquidity.
