Oil production growth was strongest in the U.S., where it grew 38% over last year due to strength in the Permian Basin and the Mississippian-Woodford Trends.

Total production of oil, natural gas and natural gas liquids was strong as well. Devon's production averaged 691,000 barrels of oil equivalent per day. That exceeded the midpoint of the company's guidance. Overall, oil and natural gas liquids, Devon's two highest margin products, now represent 43% of total production and is up from 42% last quarter.

In commenting on the quarter, CEO John Richels noted that, "Once again we significantly increased light oil production in the U.S., reflecting our continued success in the Permian Basin and emerging oil plays. Additionally, Devon's disciplined pursuit of high-margin production has improved cash margins by 16% year over year to our highest level in the past eight quarters."
