EnCana Explores Greater Sierra

EnCana Corporation has completed a major land acquisition program along the Devonian Jean Marie reef margin in the Greater Sierra region in northeast British Columbia.

The company now holds more than 2 million net acres of land on the Greater Sierra play and is firmly established as a leading explorer, producer and landholder in B.C. -- one of the fastest growing gas producing regions in North America.

EnCana considers that its Greater Sierra lands contain the largest regional gas play discovered in Western Canada in the past decade. For the last four years EnCana has been steadily acquiring mineral rights and extending the productive area of this play.

The Greater Sierra development taps the extensive Upper Devonian Jean Marie formation, a gas-rich carbonate present throughout much of northeast B.C.

The most prolific wells are located east of Fort Nelson, B.C. along the reef margin that is about 3 to 5 miles wide, extending more than 175 miles south from the Northwest Territories border to the disturbed belt of the Rocky Mountains.

Typical wells in the reef margin will produce from 2 million to 4 million cubic feet per day in the first year and then stabilize in the range of 1 million cubic feet per day with a reserve life of greater than 10 years. Each square mile of productive land on the reef margin contains an estimated 5 billion to 10 billion cubic feet of gas in place. To date, EnCana's success rate along the margin has been in the order of 90 percent.

EnCana is forecasting natural gas sales of between 2,675 million and 2,745 million cubic feet per day in 2002, a 14 percent increase in average daily gas sales compared to the 2001 combined results for Alberta Energy Company Ltd. and PanCanadian Energy Corporation.
