Triangle Petroleum Underscores 3Q Windsor Block Shale Gas Program

In July 2008, Triangle started the second stage of the Windsor Block shale gas exploration program to test the gas content and productivity of the Horton Bluff shales in various locations across the Windsor Block, and also to evaluate potential overlying conventional oil and gas reservoirs.

The first vertical exploration well in this program, N-14-A, spud in mid July 2008 and cased in August 2008. N-14-A is located approximately eight kilometers (five miles) north of Triangle's two 2007 vertical test wells. N-14-A was drilled to a depth of 2,600 meters (8,500 feet). Log, core, and lab analysis indicates a potentially gas-bearing Horton Bluff shale and sand interval, approximately 1,000 meters (3,300 feet) thick.

The second vertical exploration well, O-61-C, spud in August 2008, and was cased in October 2008. This well is located approximately 22 kilometers (14 miles) west of from N-14-A, in a separate fault block. Total depth drilled was 2,960 meters (9,700 feet). Logs indicate the presence of over 300 meters (1,000 feet) of shale within the Horton Bluff section as well as several potential tight sand intervals.

Triangle's third vertical exploration well, E-38-A, spud in late October 2008, and was cased in November 2008. The well is located in the Kennetcook area near N-14-A, but in a separate fault block. Total depth drilled was 1,700 meters (5,600 feet), and casing was run to 1,500 meters (4,900 feet). A shale section of approximately 1,000 meters (3,300 feet) is being evaluated for completion.

Completion operations commenced on the N-14-A well at the end of October 2008, with a four-stage perforation and fracture treatment taking place in early December 2008. The completion consisted of a four-stage frac treatment across a 100 meter (330 foot) interval, each stage consisting of approximately 50 tonnes (110,000 pounds) per stage.

Completion operations on the other two wells drilled in this program are being evaluated by the technical teams at Triangle and its partners. Operations will move forward on the basis of that technical evaluation, equipment availability, government approvals, and partner concurrence.
