HOUSTON, Nov. 1 -- Triangle Petroleum Corp., Calgary, has drilled two exploratory wells to the Lower Mississippian Horton Bluff shale in west-central Nova Scotia and is designing a frac to be conducted in late 2007.
Kennetcook-1, 25 miles west of Truro, NS, is cased to TD 4,390 ft and will be completed first. It was cored extensively in a 1,150-ft interval and found the primary zone of interest to be 350 ft thick and the secondary zone of interest to be 260 ft thick. Kennetcook-2, 2 miles northwest of Kennetcook-1, went to TD 6,350 ft, and logs indicate the primary shale zone to be 500 ft thick.
The program calls for a single-stage frac using 1 million gal of slick water and 550,000 lb of sand proppant. A former Mitchell Energy/Devon Energy engineer who recommended slick water fracs on the Fort Worth basin Barnett shale is managing the stimulation program.
Triangle and farmor Contact Exploration Inc. are shooting 25 sq miles of 3D seismic over the Kennetcook wells and 30 line-miles of 2D seismic on another part of the 516,000-acre Windsor Shale Block in the Windsor subbasin of the Maritimes basin (see map, OGJ, Aug. 5, 2002, p. 32).
