Brigham Exploration Announces Triple Crown Field Completions

          AUSTIN, Texas, Oct. 19 /PRNewswire-FirstCall/ -- Brigham Exploration Company (Nasdaq: BEXP) today announced the successful completion of its Sullivan C-31 and the completion of a new high production rate zone in its Dawson #2 Vicksburg development wells.

          Completion of Triple Crown Field Vicksburg Wells -- The Dawson #2 was recently recompleted in a previously untested Upper Vicksburg interval at an initial rate of 9.3 MMcfed with strong flowing tubing pressures.  This was the first completion attempt in the “Brigham” sand, which was also encountered in the currently completing Sullivan C-31 and several previously drilled Triple Crown wells.  Brigham had anticipated commingling the Brigham sand in the Dawson #2 with the previously completed 9800’ intervals, but given the unusually high pressures and high producing rates the company anticipates commingling the various pay intervals at a later date.  The 9800’ sands were producing approximately 2.7 MMcfe per day with a flowing tubing pressure of approximately 2500 psi prior to perforating the shallower Brigham sand interval.

          Brigham’s recently announced Triple Crown Field development well, the Sullivan C-31, was initially completed in the deepest potential pay interval, the Loma Blanca, at a rate of 2.8 MMcfe per day with a flowing tubing pressure of 6350 psi.  Brigham subsequently completed the shallower 9800’ sands at an initial rate of 6.4 MMcfe per day with a flowing tubing pressure of 6400 psi. Brigham is currently preparing to commingle these two zones.  The Sullivan C- 31 also encountered apparent high quality pay in the shallower Brigham sand, which will be completed and commingled at a future date.

           Brigham has drilled six Upper Vicksburg wells to date in its Triple Crown Field.  The company estimates that up to four additional wells could be drilled to fully develop the Upper Vicksburg in the Triple Crown Field, all of which have potential in the newly tested Brigham sands.  Additionally, potential exists for other Upper Vicksburg locations in adjacent fault blocks. To date only two Triple Crown Field wells have penetrated the Lower Vicksburg, and Brigham estimates that up to 18 additional locations could be drilled to fully explore and develop these deeper intervals.

          Bud Brigham, the Chairman, President and CEO stated, “The production established to date by these high working interest Triple Crown Field completions has exceeded our expectations.  Importantly, the newly established production from the Brigham sand proves up additional reserves in the Triple Crown Field for future development.”
