In 2006, Guinea signed a production sharing agreement with Hyperdynamics Corporation of Houston to explore a large offshore tract, and was recently in partnership with Dana Petroleum PLC (Aberdeen, United Kingdom). The initial well, the Sabu-1, was scheduled to begin drilling in October 2011, at a site in approximately 700 metres of water.  The Sabu-1 targeted a four-way anticline prospect with upper Cretaceous sands, and was anticipated to be drilled to a total depth of 3,600 meters.
