HOUSTON, Apr. 16 -- The Tofkat-1 well struck oil-bearing sandstone in the Kuparak formation on Alaska's North Slope, said partner Bow Valley Energy Ltd.

Tofkat-1 awaits evaluation to determine its commerciality. Log analysis confirmed an interval of 10 ft of gross pay and 6 ft of net pay.

No oil-water contact was observed, and no production test was attempted. Brooks Range Petroleum Corp., the operator, drilled two sidetrack appraisal wells.

Tofkat-1 was suspended for possible reentry as a future production well. The well is east of the Colville River (OGJ, Jan. 28, 2008, p. 42).

Partners are acquiring 210 sq miles of 3D seismic survey to be analyzed by late 2008 in preparation for an appraisal drilling program in the 2009 winter drilling season.

The 3D seismic will also be used to evaluate uphole potential in the Brookian formations.

Joint venture partners are Brooks Range Petroleum, TG World Energy Inc., Bow Valley Alaska Corp., and Ramshorn Investments Inc.
