Gulfport Receives Third-Party Assessment of Grizzly Oil Sands ULC Original Oil In Place

OKLAHOMA CITY, Sept. 25, 2007 (PRIME NEWSWIRE) -- Gulfport Energy Corporation (Nasdaq:GPOR) today reported certain information regarding Grizzly Oil Sands ULC ("Grizzly") in which Gulfport holds an approximate 25% interest.

Grizzly has received a letter from DeGolyer and MacNaughton Canada Limited ("D&M") detailing its review of the Original Oil In Place ("OOIP") on Grizzly's land holdings. D&M reviewed twenty-two lease blocks and found that at this time "there is sufficient well control on seven of these properties to prepare comprehensive geological interpretations of tar sands and volumetric assessments of the associated bitumen quantities with a minimum of 27% porosity, less than 60% shale and less than 60% water saturation cut-off."

D&M estimates total bitumen in place from these seven properties as follows:

15.8 billion barrels over an area of 260,272 acres for sands greater than zero meters of thickness; and

11.9 billion barrels over an area of 152,564 acres for sands greater than ten meters of thickness.

The properties (and formations) where OOIP have been assigned are as follows: Algar Lake (McMurray), Birchwood (McMurray, Wabiskaw), Dover (McMurray), Kodiak (McMurray), Silvertip (McMurray, Wabiskaw), Thickwood (McMurray, Wabiskaw), West Ells (McMurray).

"We are pleased that the DeGolyer and MacNaughton report validates our view of the substantial resource underlying our oil sands properties," said Jim Palm, CEO of Gulfport. "We look forward to a successful 2007-8 winter drilling and seismic program."

Grizzly is undertaking a 2007-8 winter delineation and exploration program where it plans to drill 100-120 wells and conduct a 3D seismic survey. Grizzly has already begun the environmental and regulatory process of developing its first 10,000 bbl/d SAGD (Steam Assisted Gravity Drainage) project at Algar Lake.
