HOUSTON, August 8, 2007 – Swift Energy Company (NYSE: SFY) reported today in response to investor inquiries that it has not experienced production interruption in its Lake Washington field in Plaquemines Parish, Louisiana, and production remains predominately unaffected by a recent upstream natural gas pipeline incident. Based upon current information Swift Energy does not expect any material change in this status. This pipeline event occurred on one of the pipeline systems in the area, which is not utilized by Swift Energy. The curtailment on the effected pipeline system did, however, cause increased line pressure on Swift Energy’s sales outlet at Lake Washington which caused a minor curtailment of approximately 250 barrels of oil equivalent (1%) of total Lake Washington production. This is expected to improve over the next several days.
