Brigham Drills Southern Louisiana Discovery, Boosts Production

Brigham Exploration Company announced that its Main Pass SL 18826 #1 discovery was production tested at a rate of 15.4 MMcf of natural gas per day. Brigham also drilled an apparent discovery with its second joint venture well at Chandeleur Sound.

Brigham Exploration owns a 50% working interest in both Main Pass and Chandeleur Sound, the first two of six prospects it plans to drill as part of its Southern Louisiana joint venture with Clayton Williams Energy Inc.

The Main Pass SL 18826 #1 encountered approximately 100 feet of apparent Miocene pay in four intervals at depths of between 7,140 and 7,680 feet. All intervals were commingled at a production rate of approximately 15.4 MMcf of natural gas per day with minimal pressure drawdown. Brigham anticipates achieving production to sales by late August, and expects to produce the Main Pass SL 18826 #1 at an initial rate of 15 to 20 MMcf of natural gas per day.

Brigham's second joint venture well, the Chandeleur Sound SL 19312 #1, was recently logged and encountered approximately 24 feet of apparent pay. The Chandeleur Sound SL 19312 #1 is a southern offset to a well that had produced approximately 4.0 Bcfe prior to being knocked off line by Hurricane Katrina. Brigham is currently drilling its third joint venture well, the Breton Sound SL 19054 #1, with results expected in late July. The fourth joint venture well, the Romere Pass BLM 013045 #1, is expected to commence in August.

Bud Brigham, the Chairman, President and CEO, stated, "We're two for two thus far in our Southern Louisiana joint venture with Clayton Williams. Our Main Pass well should be a remarkably strong producer, positively impacting our production beginning in September. We expect to have our Chandeleur Sound well production tested by late July, with production to sales expected in late September. Our drilling program has progressed very well thus far in 2008. We've had a 100% success rate to date, including of course our activity in the Williston Basin, where we expect to issue an update on our activity soon."
