SWIFT ENERGY ANNOUNCES RECORD FIRST QUARTER: Earnings of $25.7 Million, a 76% Increase, Earnings Per Share of $0.89 Per Diluted Share, and Cash Flow of $64.7 Million, or $2.24 Per Diluted Share-- 5-9-05

HOUSTON, May 9, 2005 - Swift Energy Company (NYSE: SFY) announced today a net income record of $25.7 million for the first quarter of 2005, or $0.89 per diluted share, a 76% increase compared to $14.6 million in net income, or $0.52 per diluted share, earned in the first quarter of 2004. Net cash provided by operating activities increased 63% to $64.7 million, or $2.24 per diluted share, compared to $39.6 million, or $1.41 per diluted share, for the first quarter of 2004.

Production increased 9% for the first quarter of 2005 to 15.5 billion cubic feet equivalent (“Bcfe”) from the 14.3 Bcfe produced in the first quarter of 2004 and decreased 2% sequentially from the 15.9 Bcfe produced in the fourth quarter of 2004. First quarter 2005 production included 11.0 Bcfe of domestic production, a 5% increase, and 4.5 Bcfe produced in New Zealand, an 18% increase, in both cases when compared to production in the same period in 2004. The increases were due to higher levels of domestic production at Lake Washington and increased natural gas production from the Kauri area in New Zealand. First quarter domestic production was affected by a third party pipeline service interruption in the Lake Washington area, which deferred approximately 0.25 Bcfe of production in the first quarter 2005.

Terry Swift, CEO of Swift Energy, commented, "Swift Energy Company has just completed another successful quarter, and as we continue to implement our strategic plan, we should realize fundamental growth and value for our shareholders. The dynamic and significantly improved commodity environment is rewarding companies with year over year production growth. In South Louisiana, recently acquired 3-D seismic data is being fully integrated into our operational plans. The 3-D seismic allows us to identify significant new drilling opportunities, while we high-grade and enhance our existing projects. In New Zealand, reserve growth opportunities will be tested with the drill bit, as we begin our Tarata Thrust exploratory drilling program with our partner, Mighty River Power."

Revenues and Expenses

Total revenues for the first quarter of 2005 increased 46% to $95.6 million from the $65.4 million of revenues generated in the first quarter of 2004. This increase is attributable to higher commodity prices and increased levels of production.

Lease operating expenses, before severance and ad valorem taxes, were $0.71 per thousand cubic feet equivalent (“Mcfe”) in the first quarter 2005, an increase of 6% compared to $0.67 per Mcfe of these expenses in the first quarter of 2004. The increase was predominately due to increased compression and chemical costs in Lake Washington and also due to higher currency exchange rates in New Zealand. General and administrative expenses increased to $0.31 per Mcfe during the first quarter 2005 from $0.28 per Mcfe in the same period in 2004. This increase was primarily attributable to expenses related to ongoing Sarbanes-Oxley compliance initiatives. Depreciation, depletion and amortization expense of $1.56 per Mcfe in the first quarter 2005 increased from $1.28 per Mcfe in the comparable period in 2004. Interest expense per unit decreased 15% to $0.41 per Mcfe in the first quarter 2005 compared to $0.48 per Mcfe for the same period in 2004. Also, severance and ad valorem taxes were up appreciably to $0.59 per Mcfe from $0.44 per Mcfe in the comparable periods due to higher commodity prices and the higher severance tax rates on crude oil from our increased crude oil production in Louisiana.

Production & Pricing

Total first quarter 2005 production of 15.5 Bcfe increased 9% from the 14.3 Bcfe produced in the same quarter of 2004 and decreased 2% when compared to production in the fourth quarter of 2004. First quarter 2005 domestic production increased to 11.0 Bcfe, an increase of 5% from the 10.4 Bcfe produced in the same quarter in 2004, primarily due to increased production from the Lake Washington area, but 2% lower than production in the fourth quarter 2004, principally due to the previously mentioned third-party pipeline interruption. First quarter 2005 New Zealand production of 4.5 Bcfe increased 18% from production in the same quarter in 2004 and decreased 1% from levels in the previous quarter.

In the first quarter of 2005, Swift Energy realized an aggregate global average price of $6.16 per Mcfe, an increase of 33% from first quarter 2004 price levels, when the price averaged $4.62 per Mcfe. Domestically, the Company realized an aggregate average price of $6.99 per Mcfe, an increase of 33% over the $5.24 received in the first quarter of 2004. In the first quarter of 2005, average domestic crude oil prices increased 39% to $47.20 per barrel from $33.95 per barrel realized in the same period in 2004. For the same periods, average domestic natural gas prices of $5.41 per thousand cubic feet (“Mcf”) increased 11% from the $4.90 per Mcf domestic average a year earlier. Prices for natural gas liquids (“NGL”) domestically averaged $31.79 per barrel in the first quarter, a 31% increase over first quarter 2004 NGL prices.

In New Zealand, Swift Energy realized an average natural gas price of $3.17 per Mcf for the first quarter of 2005 under its long-term contracts, a 40% increase over the $2.27 per Mcf received in the comparable 2004 period. Also in New Zealand, the Company’s McKee blend crude oil sold for an average $51.68 per barrel, while its NGL contracts yielded an average price of $17.80 per barrel for the first quarter 2005. The higher New Zealand natural gas price is a function of more Kauri gas being produced under newer contracts, and New Zealand natural gas sales, which are denominated in New Zealand dollars and have remained strong against the U.S. dollar.

Operations Update

Swift Energy successfully completed 13 of 17 domestic wells in the first quarter of 2005. Domestically, the Company completed 11 of 14 development wells for a success rate of 79% for the quarter. The Company successfully completed nine of 12 development wells and completed two of three exploration wells in the Lake Washington area in Plaquemines Parish, Louisiana. Additionally, the Company successfully completed two development wells in the AWP Olmos area in McMullen County, Texas. In New Zealand, the Company was unsuccessful on the Kauri-E8A well and on a previously announced shallow exploration well.

Swift Energy currently has seven wells waiting to be completed in the Lake Washington area. The Company currently has two rigs operating in Lake Washington and is planning to bring a barge rig into the Cote Blanche Island and Bay de Chene areas in the second half of 2005 and move a second rig to the AWP Olmos area this summer. As a result of this activity and oilfield inflation, Swift Energy has increased its capital expenditure budget by $20 million to a range of $220 million to $240 million for 2005.

Production facility upgrades in Lake Washington are on schedule and are expected to be completed mid-third quarter, as planned. It should also be noted that Swift Energy’s Bay de Chene Field was operating for most of the first quarter 2005, while Cote Blanche Island Field operations have only recently resumed with production being restored to the field in the second quarter.

In New Zealand, the Company is currently drilling the Kauri-E10 well and expects to begin drilling the Goss Prospect exploration well with a second rig later in the second quarter, which should be followed by the Tawa and Trapper Prospects in the Tarata Thrust exploration program. Also late in the second quarter, Swift Energy plans a fracture stimulation program on certain Kauri sand wells. The Rimu Production Station underwent routine maintenance in the second quarter and as a result Swift had reduced production levels for five days.

Swift Energy New Zealand (“SENZ”) was recently awarded offshore Petroleum Exploration Permit (“PEP”) 38495 in the Taranaki Basin on the North Island of New Zealand. The permit is located offshore in the southern portion of the basin to the south and west of Swift’s Rimu/Kauri permit (PEP 38719) and encompasses approximately 600 sq. miles. This is in addition to the previously announced Kauri Petroleum Mining Permit 38155, which was also recently awarded.

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, 2005. The Company, however, is continuing 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 price risk management update on February 17, it has continued to enter into price risk management transactions and reports the following current positions. The Company now has approximately 18% to 20% of its estimated second quarter domestic crude oil production sold at an average NYMEX strike price of $51.43 per barrel. Also, Swift Energy has 4% to 6% of its estimated third quarter oil volumes sold at an average NYMEX strike price of $56.14 per barrel. These NYMEX crude oil strike prices do not take into account transportation charges or crude oil quality differentials that could result in price reductions ranging from $2.00 to $3.00 per barrel.

Swift Energy has purchased floors covering 57% to 61% of its estimated domestic natural gas production in the second quarter 2005 at an average NYMEX strike price of $5.77 per Mcf and 42% to 47% of estimated third quarter 2005 production covered by floors at an average NYMEX strike price of $5.60 per Mcf. For the fourth quarter 2005, Swift has 18% to 20% of its estimated natural gas production covered by floors at an average NYMEX strike price of $5.63 per Mcf. Details of Swift Energy’s complete price risk management activities can be found on the Company’s website (www.swiftenergy.com).
