Williston Basin

Acreage Growth to over 240,000 Net Acres with over 88,000 Net Acres in Mountrail County & Extensional Areas -- Brigham has grown its acreage position in the Williston Basin to over 240,000 net acres. Most of the recent growth has occurred east of the Nesson Anticline in Mountrail County and extensional areas where Brigham now controls over 88,000 net acres, approximately 40,300 net acres of which are located in Mountrail County. Approximately 7,000 net acres are generally proximal to the Parshall Field and EOG's Austin discoveries, while roughly 26,000 net acres are located in the Ross area, generally between the Parshall Field area and the Nesson Anticline. An additional 7,300 net acres are located in Mountrail County in the North Stanley area, which is approximately 15 miles northwest of the EOG Austin wells, and approximately 12 miles north of the Brigham operated Bakke 23 #1H. Approximately 48,000 net acres are located in undisclosed extensional areas to the east of the Nesson Anticline.

To the west of the Nesson Anticline in McKenzie and Williams Counties, North Dakota, Brigham controls Bakken rights on approximately 51,000 net acres. In eastern Montana, where Brigham drilled its recent Red River discovery, Brigham controls all rights on roughly 100,000 net acres in Sheridan and Roosevelt Counties.

Mountrail County Bakken Drilling and Completion Activity -- Brigham successfully drilled and completed its fourth operated Mountrail County horizontal Bakken well, the Hallingstad 27 #1H. Subsequent to fracture stimulation the Hallingstad 27 #1H produced at an early rate of approximately 450 Boe per day up 4.5" casing. Northern Oil and Gas Inc. participated in the Hallingstad 27 #1H with a 8.4% working interest, which increases to a 20% working interest after payout. The Hallingstad 27 #1H is located approximately one mile west of the Bergstrom Family Trust 26 #1H well and approximately four miles northeast of the Parshall Field.

Subsequent to drilling the Hallingstad 27 #1H, Brigham commenced the Manitou State 36 #1H, which is currently drilling at a depth of approximately 9,000 feet. The Manitou State 36 #1H is located approximately one mile northeast of the Brigham operated Hynek 2 #1H and approximately five miles northwest of the Brigham operated Bakke 23 #1H. Following the Manitou State 36 #1H, Brigham plans to commence the Johnson 33 #1H in the North Stanley area, where Brigham controls approximately 7,300 net acres. Brigham currently plans to keep this operated rig running continuously to drill horizontal Bakken wells in North Dakota.

Brigham has installed 2 7/8" production tubing and pumping units on its first three Mountrail County horizontal Bakken completions. The Bakke 23 #1H is currently producing approximately 310 Boe per day, the Hynek 2 #1H is producing approximately 142 Boe per day, and the Bergstrom Family Trust 26 #1H is producing approximately 119 Boe per day.

Bud Brigham, the Chairman, President and CEO stated, "We're encouraged by the early results of the Hallingstad 27 #1H, which appears to be a strong producer. Approximately five miles to the west of the Hallingstad 27 #1H, EOG has completed the Austin 26 #1H in section 2 of 154N-90W, which they reported to have produced at an early rate of approximately 3,060 barrels per day. We have a meaningful acreage position within a few miles of the Austin 26 #1H, including interests in two sections directly offsetting the discovery. Our larger working interest directly offsets the Austin 26 #1 to the South where we own a 25% interest and is reportedly planned to be drilled this year. As shown on our Mountrail area map in our corporate presentation, we control approximately 7,000 net acres in the Parshall Field area, including acreage offsetting EOG's three previously announced high rate Austin discoveries in sections 2, 4 and 9 of T154N-R90W. Provided the area is developed on 640 acre spacing roughly 11 net wells would be drilled, double that if 320 acre spacing is validated, which we believe to be likely. Given the accelerating drilling pace announced by several of the operators, we expect drilling in this area to meaningfully impact our production and reserves in 2008 and subsequent years."

Bud Brigham continued, "Subsequent to drilling the Manitou State 36 #1H, we'll commence the Johnson 33 #1H in our North Stanley area. We believe this area has many attributes in common with the Parshall/Austin area, and it is about 17 miles northwest and generally on trend with those producers. In total, the 88,000 net acres we've accumulated in the play east of the Nesson Anticline, including approximately 40,300 of which is in Mountrail County, provides us with the potential to drill 137 to 275 net wells, depending on spacing. Given our size, we believe we've accumulated the most impactful acreage position in the Bakken play. This year, we expect to drill or participate in the drilling of at least seventeen gross, or six net wells in the play in at least four different areas."
