Senegals Natural Gas reserves are primarily located onshore. In October 2002, U.S.-independent Fortesa International began natural gas production from the onshore Gadiaga Development Area, with current production at two MMcf/d of natural gas. Fortesa holds a 70 percent stake in Gadiaga, with the remaining 30 percent held by Petrosen, the Senegalese national Oil company. In December 2005, Fortesas Sadjiratou-1 natural gas Well tested positive and the company has plans to drill another test well in 2006. Petrosen anticipates that Tullow Energy, Hunt Oil and Edison will drill additional test wells in 2007.
