   --------------------------------------------

    HOUSTON--(BUSINESS WIRE)--Feb. 11, 2004--Swift Energy Company
(NYSE:SFY)  announced today that its net income for the fourth quarter
of 2003 increased 182% to $9.5 million, or $0.34 per diluted share,
compared to $3.4 million, or $0.12 per diluted share, in the fourth
quarter of 2002. Net income before accounting change (excluding the
effect of SFAS 143 implemented January 1, 2003) for the full year 2003
increased 187% to $34.3 million, or $1.24 per diluted share, compared
to $11.9 million, or $0.45 per diluted share, for the full year 2002.
Included in these results is a reduction in the consolidated income
tax expense of approximately $1.3 million ($0.05 per diluted share)
from the U.S. statutory rate, primarily the result of the currency
exchange rate effect on the deferred New Zealand tax, partially
offset by higher deferred state taxes and other items.
    Production for 2003 increased to an annual record of 53.2 billion
cubic feet equivalent ("Bcfe"), an increase of 7% from 2002 production
of 49.8 Bcfe. Production for the fourth quarter of 2003 was 13.4 Bcfe,
which was a 6% increase from the 12.6 Bcfe produced in the fourth
quarter of 2002, and a 2% decrease from the 13.6 Bcfe produced in the
third quarter of 2003. The quarter-to-quarter decrease was primarily
due to reduced throughput at Lake Washington resulting from downtime
to install new infrastructure and from reduced nominations for natural
gas in New Zealand. Fourth quarter 2003 production included 8.8 Bcfe
of domestic production and 4.6 Bcfe produced in New Zealand.
    Terry Swift, President and CEO, noted that "Swift Energy has just
completed one of its best yearly financial performances in the history
of the Company. While we celebrate the Company's 25th anniversary in
2004, we believe our operational performance will again be record
setting. In the Lake Washington Field, for instance, we produced more
than 12,000 gross barrels of oil equivalent per day (10,000 net
barrels of oil equivalent per day) in January 2004, which compares to
approximately 5,000 gross barrels of oil equivalent per day
(approximately 4,100 net barrels of oil equivalent per day) in January
2003. The diversification in our reserve and production base over the
past two years provides Swift Energy with a strong foundation for
additional growth into the coming years."

    Revenues and Expenses

    Total revenues for the fourth quarter of 2003 increased 31% to
$53.1 million from the $40.5 million of revenues received in the
fourth quarter of 2002. Total revenues for the full year 2003 were
$208.9 million, up 39% from $150.0 million in 2002. Swift Energy's
increased revenues for the fourth quarter and full year 2003 are
attributable to higher commodity prices and increased levels of
production.
    Lease operating expenses, before severance and ad valorem taxes,
were $0.63 per thousand cubic feet equivalent ("Mcfe") in 2003, an
increase of 7% compared to $0.59 per Mcfe in 2002. The increase was
predominately due to some of the facility enhancement costs in Lake
Washington and also due to currency exchange rates in New Zealand.
General and administrative expenses increased to $0.27 per Mcfe during
2003 from $0.21 per Mcfe in 2002. This increase was mainly
attributable to front-end costs associated with increased activity
levels at Lake Washington and corporate governance expenses.
Depreciation, depletion and amortization expense was $1.19 per Mcfe in
2003 compared to $1.13 per Mcfe in 2002, and interest expense was
$0.51 per Mcfe compared to $0.47 per Mcfe for the same periods. Also,
severance and ad valorem taxes were up appreciably to $0.36 per Mcfe
from $0.24 per Mcfe due to higher commodity prices and the higher
severance tax rates on crude oil from our increased crude oil
production in Louisiana.

    Reserves

    Swift Energy again made significant strides in 2003 in improving
the quality and the quantity of its reserves. Year-end 2003 proved
reserves of 820 Bcfe were 47% crude oil, 41% natural gas and 12%
natural gas liquids ("NGLs"), compared to year-end 2002 proved
reserves of 749 Bcfe, which were 44% natural gas, 42% crude oil and
14% NGLs. Proved developed reserves remained essentially the same at
59% of total reserves at year-end 2003, compared to 60% in the
previous year. The majority of proved undeveloped reserves at year-end
2003 were located in the Lake Washington area (13% of total reserves)
and in the AWP Olmos area (9% of total reserves), both of which are
characterized as long reserve life fields.
    Domestic proved reserves increased at year-end 2003 to 644 Bcfe,
driven mainly by the reserves increase in the Lake Washington Field,
which increased 37% to 261 Bcfe (43.5 million barrels of oil
equivalent) up from 190 Bcfe (31.7 million barrels of oil equivalent)
at year-end 2002. Domestic proved reserves at year-end were 49% crude
oil, 38% natural gas and 13% NGLs. Domestic proved reserves, making up
79% of total proved reserves at year-end 2003, are located in the Lake
Washington area (32% of total reserves), AWP Olmos area (26% of total
reserves), Masters Creek area (8% of total reserves), Brookeland area
(5% of total reserves) and other domestic properties (7% of total
reserves).
    In New Zealand, 2003 year-end proved reserves increased 13% to 176
Bcfe, 64% of which are categorized as proved developed reserves. New
Zealand reserves constitute 21% of the Company's total proved reserves
with 15% of total reserves attributable to the Rimu/Kauri area and 6%
to the TAWN area. New Zealand proved reserves consist of 53% of
natural gas, 38% of crude oil and 9% of NGLs. The 2003 increase in
reserves was primarily attributable to drilling additions in the Kauri
and Manutahi Sands.

    Production & Pricing

    For 2003, total production increased 7% to 53.2 Bcfe from 49.8
Bcfe in 2002. Domestically, 2003 total production decreased by 1% to
33.8 Bcfe compared with 34.3 Bcfe from 2002 levels but quarterly
production increased throughout 2003 as the Company continued to focus
its efforts and capital towards the development of longer life oil
reserves in the Lake Washington area. During 2003, the Company also
began allocating capital to natural gas development in its three other
domestic core areas. New Zealand accounted for 36% of corporate
production with 19.4 Bcfe produced in 2003, an increase of 25% from
the 15.5 Bcfe produced there in 2002.
    Total fourth quarter 2003 production of 13.4 Bcfe increased 6%
from the 12.6 Bcfe produced in the same quarter of 2002 and decreased
2% from third quarter 2003 production. Fourth quarter 2003 domestic
production of 8.8 Bcfe increased 16% from the 7.6 Bcfe produced in the
same quarter in 2002. Fourth quarter 2003 New Zealand production of
4.6 Bcfe decreased 8% from 5.0 Bcfe produced in the same quarter in
2002, due to lower nominations of natural gas in the TAWN area because
of reduced demand.
    In 2003, Swift Energy realized substantially higher average
domestic natural gas prices of $5.07 per thousand cubic feet ("Mcf"),
an increase of 69% from the $3.01 per Mcf domestic average in 2002.
Meanwhile, average domestic crude oil prices increased 22% to $29.95
per barrel from $24.57 per barrel realized in 2002. Prices for NGLs
domestically averaged $19.75 per barrel in 2003, a 50% increase over
the 2002 NGL prices.
    In New Zealand, Swift Energy received an average natural gas price
of $1.83 per Mcf for 2003 under its long-term contracts, a 38%
increase over the $1.32 per Mcf received in 2002. Also in New Zealand,
the Company's McKee blend crude oil averaged $29.58 per barrel and the
Company's NGL contracts yielded an average price of $13.50 per barrel
for the year 2003. New Zealand natural gas and the NGL price contracts
are denominated in New Zealand dollars, which has significantly
strengthened during 2003 against the U.S. dollar. The currency
exchange rate increased to approximately $0.66 U.S. dollars per $1.00
New Zealand dollar at the end of 2003 compared to approximately
US$0.52 to NZ$1.00 at the end of 2002 (a 25% increase).
    In the fourth quarter of 2003, Swift Energy realized an aggregate
global average price of $3.97 per Mcfe, an increase of 26% from fourth
quarter 2002 price levels, when the price averaged $3.15 per Mcfe.
Domestically, the Company realized an aggregate average price of $4.59
per Mcfe, an increase of 17% over the $3.93 received in the fourth
quarter of 2002. In New Zealand, the Company received an aggregate
average price of $2.78 per Mcfe for the fourth quarter in 2003, an
increase of 41% over the $1.97 per Mcfe realized in 2002.

    Domestic Operations

    Swift Energy completed 13 of 16 wells domestically in the fourth
quarter of 2003. Of these 16 wells, 15 were development wells and one
was an exploration well. In Lake Washington, the Company completed
eight of 10 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 Brookeland area and
completed four wells in the AWP Olmos area. For the full year 2003,
the Company completed 53 out of 63 domestic development wells and five
of eight exploration wells. Currently, the Company has one rig
operating in Lake Washington and one rig in the AWP Olmos area as well
as the Masters Creek area.

    New Zealand Operations

    Swift Energy completed three of four wells in New Zealand during
2003. Two of these wells successfully targeted the Kauri Sand, the
third was completed in the Manutahi Sand, and the fourth well was an
unsuccessful exploration test. The Company also fracture stimulated
three Kauri Sand wells in 2003. The Company recently drilled the
Kauri-E3 well, which is waiting on a fracture stimulation, and also is
in the process of drilling the Kauri-E4 well.

    Price Risk Management

    Swift Energy also announced that since its last update on January
26, it has continued to enter into price risk management transactions.
The Company recently purchased additional natural gas floors that
cover 200,000 million British thermal units ("MMBtu") per month for
the second quarter of 2004, all at a strike price of $5.00 per MMBtu.

    Guidance

    Due to the January 2004 production levels recorded in the Lake
Washington area and expected production levels for the first quarter
2004, Swift Energy is increasing its domestic production guidance
range for the first quarter 2004 to 10.0 to 10.5 Bcfe from the 9.7 to
10.2 range disclosed at its Analyst/Investor meetings in January 2004.
Total production for the first quarter of 2004 is expected to be 13.5
Bcfe to 14.5 Bcfe. Except for changes in the domestic product mixes,
all other guidance estimates remain the same.

   (1) SFAS 143 - Statement of Financial Accounting Standards No. 143
        (SFAS No. 143), "Accounting for Asset Retirement Obligations,"
        which requires companies to record the present value of
        estimated future abandonment obligations as a liability, with
        a corresponding entry to oil and gas assets.
   (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.
