             Swift Energy Announces First Quarter Results

    HOUSTON--(BUSINESS WIRE)--May 7, 2003--

           247% Increase in Income before Accounting Change
                    to $10.5 Million ($0.38/Share)

                Production Increase of 5% to 12.9 Bcfe

    Swift Energy Company (NYSE:SFY) (PCX:SFY) announced today that
income before the cumulative effect of an accounting change increased
247% in the first quarter of 2003 to $10.5 million, or $0.38 per
diluted share, compared to net income of $3.0 million, or $0.12 per
diluted share, in the first quarter of 2002, primarily as the result
of higher prices.
    The Company's net income was $6.1 million or $0.22 per diluted
share, including the cumulative effect of the accounting change. The
Statement of Financial Accounting Standards No. 143 (SFAS 143)
implemented January 1, 2003, is a mandated accounting change that
amounted to a one-time charge for the Company of $4.4 million (net of
tax), or $0.16 per diluted share. SFAS 143 "Accounting for Asset
Retirement Obligations" requires companies to record the present value
of estimated future abandonment obligations as a liability, with a
corresponding increase in oil and gas assets.
    Production increased 5% to 12.9 Billion cubic feet equivalent
("Bcfe") in the first quarter of 2003 from 12.3 Bcfe of production in
the first quarter of last year. Production increased 2% from fourth
quarter 2002 levels. Domestic production was 7.7 Bcfe, and New Zealand
production was 5.2 Bcfe for the first quarter of 2003.
    Terry Swift, President and CEO of Swift Energy Company, noted, "We
started the year with good operational success, and we have certainly
been buoyed by the strong pricing environment. Our principal goal for
the year is to deliver added value by meeting our production and
reserve targets, while improving our operating margins. Despite the
temporary partial shut-in at Lake Washington, we continue to make
progress on our goals. In order to take advantage of today's domestic
natural gas market, we are now accelerating several budgeted natural
gas wells and fracture stimulations that were planned to take place
later in the year. New Zealand activity also has been promising this
year, with the doubling of net sales during the first quarter 2003
compared to the same quarter last year, and the successful
implementation of several projects in the first-half of 2003.
Second-half drilling plans will allow us to better evaluate both the
Kauri and Manutahi sands."

    Revenues & Expenses

    Total revenues for the first quarter 2003 totaled $53.5 million,
an increase of approximately 56% from revenues of $34.4 million during
the first quarter in 2002. Total revenue for the first quarter of 2003
is net of $1.4 million of losses from derivative product price hedging
activities, which compares with a $0.1 million gain from such
activities for the first quarter of 2002. Cash flow before changes in
working capital increased 176% to $31.6 million ($1.16 per diluted
share) in the first quarter of 2003 compared to $11.5 million ($0.45
per diluted share) in the first quarter of 2002. Net cash provided by
operating activities increased 147% to $26.8 million ($0.98 per
diluted share) compared to $10.8 million ($0.43 per diluted share) in
the first quarter of 2002.
    Controllable lease operating expenses improved nearly 2% on a per
unit basis compared to the first quarter of 2002. During the same
period, general and administrative costs increased, both in total and
on a per unit basis, primarily as a result of the increased costs
associated with certain corporate governance actions taken in response
to the recently enacted Sarbanes-Oxley Act and related regulations and
also due to lower reimbursements due to the recent liquidation and
dissolution of all public partnerships managed by the Company.

    Production & Pricing

    Domestic production was 7.7 Bcfe in the first quarter 2003, a 20%
decline from 9.7 Bcfe of production in the first quarter of 2002.
However, domestic production did increase 1% from fourth quarter 2002
levels and was above the Company's most recent guidance. Despite this
modest increase, there were two distinct events that negatively
affected our domestic production levels for the quarter. The
previously reported partial shut-in of the Lake Washington Field, in
Plaquemines Parish, Louisiana, lowered production in the first quarter
of 2003 by approximately 0.7-1.0 Bcfe. It is anticipated that second
quarter production will also be reduced by a similar amount, as is
reflected in the updated second quarter and full-year 2003 guidance
that is part of this press release. Additionally, due to the
relatively higher natural gas price as compared to the crude oil price
during the first quarter, the Company elected to not process and
separately sell the natural gas liquids ("NGLs") in certain fields in
the first quarter. This practice improves the economics of the natural
gas sold; however, it reduces NGL volumes. Natural gas accounted for
47% of domestic production during the first quarter and 60% of total
production.
    In New Zealand, the Company produced 5.2 Bcfe, a virtual doubling
over the same quarter production last year and an increase of nearly
4% from production levels in the fourth quarter of 2002. Higher
natural gas demand in New Zealand has allowed the Company to both
increase production from the TAWN fields, as well as increase the
realized price received. Normal maintenance will occur at both the
TAWN and Rimu production facilities in the second quarter and is
expected to last about seven to ten days at each facility, which also
is reflected in the Company's forward guidance included with this
press release.
    The first quarter culminated in significantly higher commodity
prices: average domestic natural gas prices received in the first
quarter were $6.03 per thousand cubic feet ("Mcf"), a three-fold
increase from the $1.94 per Mcf received a year earlier, while crude
oil prices averaged $32.80 per barrel, up 71% from crude oil prices in
the previous year's first quarter. Condensate and natural gas liquids
prices received domestically also increased significantly over those
in the first quarter of 2002, providing a composite average domestic
price for the quarter of $5.68 per thousand cubic feet equivalent
("Mcfe"), which was 145% more than the $2.32 per Mcfe received in the
first quarter of 2002, and 45% more than the $3.93 per Mcfe received
in the fourth quarter of 2002.
    In New Zealand, the Company has seen its average realized price
increase for five straight quarters due to a beneficial currency
exchange rate and non-contracted natural gas sales into the tightening
New Zealand gas market. The composite average price for New Zealand
was $2.15 per Mcfe, a 35% increase over prices received in the first
quarter of the previous year. Similar increases over prices received
in the same quarter last year were seen on an individual product
basis, with the Company receiving an average price of $1.62 per Mcf
for its natural gas in 2003, a 34% increase from $1.21 received in
2002; $32.36 per barrel of crude oil in 2003, up 65% from $19.67 per
barrel averaged in 2002; and $12.89 per barrel for natural gas liquids
in 2003, a 31% increase from $9.81 per barrel averaged in 2002.

    Domestic Operations

    The Company successfully drilled 13 of 19 wells in the first
quarter. The Company has successfully drilled two additional wells,
one in Lake Washington and one in the AWP/Olmos area, since the last
update on April 28, bringing the year-to-date total to 19 successes
out of 25 wells drilled. The Company currently has two drilling rigs
working in Lake Washington, one rig operating in the AWP/Olmos area in
McMullen County, Texas and one rig scheduled to spud a well in the
Brookeland Field in Newton County, Texas in mid-third quarter. One
non-operated rig is also working in the Garcia Ranch area in Kenedy
County, Texas.
    Scheduled facility upgrades are underway in the Lake Washington
Field that are expected to bring capacity to over 14,000 barrels per
day gross processing capacity during the third quarter.

    New Zealand Operations

    As previously reported, the Company successfully drilled the
Kauri-F1 well, targeting the shallow Manutahi Sand, in the first
quarter and expects to install a pumping unit on that well to begin a
prolonged production test. The Kauri-A4 well that was fracture
stimulated in the first quarter, more than doubling initial test
rates, is scheduled to be connected to the Rimu Production Station in
the third quarter of this year. The Rimu-A2A well was treated with a
CO2 injection in an attempt to improve the Tariki Sand performance and
is currently undergoing further evaluation. The Company currently
plans to drill two delineation wells in the Kauri Sand, several
additional Manutahi wells and one to two exploration wells in the
second half of the year.

    Bank Borrowing Base

    As previously reported, the Company's borrowing base was recently
reaffirmed at $195 million, effective May 1. Due to improving market
conditions and expectations for higher levels of cash flow, the
Company has requested that its commitment amount with its bank group
be reduced to $150 million effective May 9, 2003. Under the terms of
its credit facility, the Company can increase this commitment amount
back to the total amount of the borrowing base, at its discretion.

Section 21E of the Securities Exchange Act of 1934, as amended. The
opinions, forecasts, projections, guidance or other statements other
than statements of historical fact, are forward-looking statements.
These statements are based upon assumptions that are subject to change
and to risks, especially volatility in oil or gas prices, and lately
availability of services and supplies. Although the Company believes
that the expectations reflected in such forward-looking statements are
reasonable, it can give no assurance that such expectations will prove
to have been correct. Certain risks and uncertainties inherent in the
Company's business are set forth in the filings of the Company with
the Securities and Exchange Commission. Estimates of future financial
or operating performance provided by the Company are based on existing
market conditions and engineering and geologic information available
at this time. Actual financial and operating performance may be higher
or lower. Future performance is dependent upon oil and gas prices,
exploratory and development drilling results, engineering and geologic
information and changes in market conditions.
