Devon Energy Corp. executives said Thursday they have completed most of the company's previously announced layoffs of about 300 employees, or 9 percent of the company's workforce.

The cuts include about 240 employees in Oklahoma City, with the remainder in Canada and at Devon's U.S. field offices.

Affected workers in Oklahoma City and Canada have been notified, and affected field workers will be notified by early next week, the company said.

Devon executives announced the layoffs earlier this month, saying the changing oil and natural gas industry has led companies to focus on fewer, stronger fields and wells, requiring fewer employees.
