During 2006, Chesapeake successfully integrated the November 2005 $3 billion acquisition of Columbia Natural Resources and began laying the groundwork for future growth and value creation from the area. Our 2006 reserve and production growth from Appalachia benefited from an accelerated drilling program and exceeded our expectations. Often referred to as America’s most drilled, but least explored area, Appalachia presents abundant growth opportunities through the application of leading-edge exploration, drilling and production technologies in which Chesapeake is a recognized industry leader. We are currently assessing the potential of deeper drilling opportunities and will be aided by a substantial amount of new proprietary 3-D seismic data. In addition, we are pursuing a variety of new initiatives to develop unconventional shales in Alabama, southern Illinois and western Kentucky and will drill our first operated horizontal shale well in Appalachia in mid-2007.
