Brigham Exploration Updates Operations

Brigham Exploration Company announced the plugging of its Cotten Land #2S2 as a dry hole, the successful completion of its Sullivan C-36 Vicksburg well, and that it has grown its acreage in the North Dakota Mountrail County area Bakken play to almost 40,000 net acres.

Southern Louisiana Bayou Postillion Project, Iberia Parish - The Brigham operated Cotten Land #2S2 well is being plugged as a dry hole. The well encountered the apparent targeted interval wet without any gas column, in a structurally high position relative to the down dip producers.

Successful Home Run Field Completion in Brooks County, Texas - Brigham successfully completed the Sullivan C-36 in late August at an initial rate of approximately 5.5 MMcfe per day, with additional pay behind pipe for future completion.

Brigham is participating in completing its first two horizontal Bakken wells in Mountrail County, North Dakota, with very small non-operated working interests. The EOG operated Risan 1-34H, located in the Parshall Field area, was recently successfully completed.

At the western end of the play near the Nesson Anticline, the Hess operated En-Hegland 156-94-3229H-1 is also being completed after encountering good drilling shows. Approximately 15 miles north of the En-Hegland 156-94-3229H-1, Brigham’s third small working interest well, the Petrohunt Torgerson 15B-2-2H, is currently drilling.

Several additional wells are either being completed, are drilling, or are permitted to be drilled offsetting Brigham’s growing acreage position. Brigham plans to commence two to three high working interest wells in this area during the fourth quarter. The company has grown its total acreage in the Mountrail County North Dakota area to almost 40,000 net acres, over 28,000 acres of which is located in Mountrail County.
