The company has built a portfolio of exploration and production assets in Africa and the Middle East. The exploration portfolio increased significantly in potential prospectivity through the signing of the Sangaw North PSC in Kurdistan, which is the focus of the company's activities. Continued exploration success by other operators confirms the highly prospective nature of the Kurdistan region. In May 2009, Heritage reported an oil discovery at Miran West, 40km north of Sangaw North-1. Further north Gulf Keystone reported an oil discovery at Shaikan in August 2009 in the same Cretaceous and Jurassic reservoirs being targeted by the Sangaw North-1 well.
