OKLAHOMA CITY (AP) ¿ Independent oil and gas producer Devon Energy Corp. on Monday said it successfully drilled a Haynesville Shale well in San Augustine County, Texas.

The Kardell Gas Unit 1H well achieved an average continuous 24-hour flow rate of about 30.7 million cubic feet of natural gas equivalent per day.

"With a flow rate of more than 30 million cubic feet per day, we believe the Kardell well is the highest rate well ever drilled in the Haynesville Shale," said David Hager, executive vice president of exploration and production.

Devon owns a 48 percent working interest in the well, which was drilled 18,350 feet deep. Crimson Exploration Inc. owns the remaining 52 percent working interest.

The Kardell well is the company's first well in San Augustine County. Its success prompted plans to accelerate drilling activity in the area, the company said. Devon's southern Haynesville Shale acreage is made up of 47,000 net acres mainly located in the Texas counties of San Augustine and Sabine and in Sabine Parish, La. Devon holds a 100 percent interest in its primary term leases in the southern area.
