J. Russell Porter, Gastar's President and Chief Executive Officer, made the following comment, "We are pleased with our reported increases in production, revenue and EBITDA. We anticipate continued improvement in operating results during 2006 as we implement a more active drilling program in the deep Bossier play and on our Australian coal bed methane properties. Our 2006 Donelson #1 discovery is currently producing at an approximate gross rate of 7.5 MMcfd (net 5.6 MMcfd) and appears to be stabilizing from the initial gross production rate of 11 MMcfd. The Donelson #1 is our first commercial production in the lower Bossier sands and appears to support Gastar's overall geologic and geophysical model in these formations."
