With a reservoir thickness of up to 150 feet of oil-bearing sands, Christina Lake is estimated by EnCana to have an unbooked resource potential of about 1.8 billion barrels of oil.

Foster Creek

In-situ oilsands, northeast Alberta, commenced commercial operations in 2001.

Foster Creek is the quintessential resource play — a high-quality, unconventional resource with large potential and scalable, repeatable operations that enable the company to incorporate technical advances.

Foster Creek produces from the McMurray formation of the Athabasca oilsands, and features a technology called steam-assisted gravity drainage (SAGD). We conducted a multi-year pilot project prior to starting commercial operations in 2001. In SAGD, horizontal wells are drilled in pairs — running parallel above one another about 17 feet apart. Steam is injected in the upper well to warm the bitumen and make it less viscous so it can drain to the lower production well bore.

A critical SAGD thermal efficiency measure is the ratio between the quantity of steam injected and the quantity of oil produced. Our steam-oil ratio of 2.5 times is industry leading. With a high-quality reservoir and leading thermal efficiency, Foster Creek delivers excellent returns.

Oil production averaged 29,019 bbls/d in 2005. In the fourth quarter of 2005, we completed the first

stage of an expansion which added an additional 10,000 bbls/d of capacity. The second stage of the expansion, which is expected to add an additional 20,000 bbls/d of capacity, is expected to be completed around year-end 2006.

In November of 2005, we announced that EnCana is developing plans to significantly expand production from its estimated 5 billion to 10 billion barrels of recoverable oilsands resources - assets that have the potential to reach a production rate of 500,000 bbls/d of oil per day in the next 10 years.
