Devon Energy Provides Preliminary Report on Severe Weather Damage to Cana Plant

Devon Energy Corporation (NYSE:DVN) today reported that its Cana gas processing plant in Canadian County, Oklahoma sustained significant damage from a tornado on May 24, 2011. Approximately 36 million cubic feet of natural gas and 2,000 barrels of natural gas liquids per day, net to Devon’s interest, are curtailed as a result of the plant outage. In spite of the curtailment, Devon continues to produce approximately 100 million cubic feet per day of natural gas and 5,000 barrels of natural gas liquids per day from the Cana field.

At the time of the incident, the plant had been temporarily shut-in as a precautionary measure. In addition, all plant personnel had been evacuated to on-site storm shelters.

"Our preliminary assessment indicates that it could take up to three months to repair the plant and fully restore production,” said Dave Hager, Devon’s executive vice-president of exploration and production. "We expect the impact on Devon’s full-year production to be less than one half of one percent.”
