HOUSTON (AP) -- Noble Energy CEO Charles Davidson is retiring in the fall after more than a decade leading the oil and gas producer.

Davidson, 64, will stay on as chairman until May 2015, ending a stretch at the company that began in 2000.

President and Chief Operating Officer David Stover will take over the top job in October.

Stover, 56, joined Noble Energy in 2002. Before that, he worked at oil companies BP, Vastar Resources and Atlantic Richfield.

Houston's Noble Energy has production and exploration facilities in the inland U.S., the Gulf of Mexico, the Mediterranean Sea and off the west coast of Africa.
