In 2006, eight wells were drilled in the South Texas region, of which seven were successful including the Scott & Hopper 5-well producing 400 Mcfed (gross), 140 Mcfed (net); two wells in the South Texas Olmos exploration project producing 300 Mcfed (gross), 80 Mcfed (net) and three wells in the South Texas royalty acreage producing 4 Mmcfed (gross), 1 Mmcfed (net).
