A Calgary research firm has mapped and plotted 75 wells in East Texas and North Louisiana's Haynesville shale. More details are thus emerging and the location of the sweet spots is becoming clear. In fact there may be more than one sweet spot. But, says the May 2009 report from Ross Smith Energy Group Ltd., "What seemed like a dream during the leasing frenzy a year ago may turn into a nightmare for some operators. This play is highly variable and some areas will require $10-plus Nymex to break even." Based on results from 53 wells studied in Louisiana, a core area is emerging. The Group concludes that Petrohawk Energy Corp.'s Bossier Parish results are still unmatched by any other company, and that the Houston firm's results in DeSoto and Red River parishes also are superior to other E&Ps drilling in the same general area. Wells in Harrison County in East Texas are showing shallower decline curves than wells in Louisiana. However, it appears their estimated ultimate recovery (EUR) numbers may be lower as well. "Press-released IP rates can be very misleading when compared to actual monthly data reported to the state," the report cautions.
