UNITED STATES - FEBRUARY 11: Aubrey McClendon, chairman and chief executive officer of Chesapeake Energy Corp., speaks during the Cambridge Energy Research Associates CERAWeek 2009 conference in Houston, Texas, U.S., on Wednesday, Feb. 11, 2009. Chesapeake, the petroleum producer that lost 59 percent of its market value last year, is more interested in boosting demand for natural gas in the U.S. than exporting the fuel in a liquefied form, McClendon said.
