Husky Energy Extends Production Life at Taber South Mannville B Pool
Husky Energy has successfully implemented Alkaline-Surfactant-Polymer (ASP) flood technology in Canada to extend the production life of the Taber South Mannville B Pool, in the Warner field.
The construction of the Taber South Mannville B Pool project, which is located 24 kilometers south of Taber, Alberta, was completed on-time and on-budget, and started up in May 2006. The $70-million project, which is the first of its kind in Canada, has been awarded a grant of $10 million under the Government of Alberta's Innovative Energy Technologies Program.
"The successful implementation of the ASP technique means that a significant number of reservoirs in Alberta may benefit from the knowledge gained from this technology," said Mr. Lau. "Currently, a large volume of oil remains in the ground after conventional oil recovery methods have been implemented. ASP flooding technology is a recovery method designed to extract remaining oil for certain reservoirs and ultimately extend the life of those reservoirs."
The Taber South Mannville B Pool, which is nearing the end of its productive life, was identified as a pilot candidate for ASP technology as the reservoir has been in production since 1963. The Warner project is targeting an incremental recovery of 4 to 6 million barrels of oil equivalent. Results since start-up are in line with Husky's pre-project reservoir engineering estimates.
Husky injects alkaline surfactant polymer followed by a polymer. The surfactant agents act to free oil trapped in the pore spaces of the reservoir and the polymer increases the area of the reservoir sweep. Water flooding resumes after chemical injection to produce oils released by the injected chemicals. The ASP flood technology is now being applied to certain mature reservoirs in Husky. A similar project at the Crowsnest field near Taber, is currently in detailed design phase.
