The production growth was concentrated in onshore fields within the United States and Canada. Devon has increased oil and natural gas production from retained properties for eight consecutive quarters.

Sales of oil, gas and natural gas liquids increased 52 percent to $3.2 billion in the first quarter of 2008. The combined effects of increased oil and gas production and higher oil, gas and natural gas liquids prices led to the increase in sales.
