HOUSTON (Reuters) -Exxon Mobil will take 18 to 24 months to achieve its full production synergies from its $60 billion purchase of U.S. shale oil producer Pioneer Natural Resources, the company's top shale executive said on Friday. Exxon this week closed all-stock acquisition after agreeing to an antitrust consent order that barred the former Pioneer CEO from joining its board and is moving in coming weeks to combine operations that will form the largest oil producer in the Permian basin. "You will see (oil production) grow pretty rapidly, year over year," said Bart Cahir, Exxon's senior vice president of shale, as Exxon applies its current growth strategy to the resources incorporated from Pioneer.
