Bengal Energy announced that hydraulic stimulation has successfully been completed on wells in the ATP 752 Barta Block in the Cooper Basin of Queensland, Australia. Four stimulated wells placed back on production have achieved an aggregate gross increase of more than 200 B/D of oil. The fifth stimulated well was slated to be tested. The results have exceeded technical and commercial expectations, the company said. Bengal has a 30.36% working interest in the block, which is operated by Santos.
