Paper Summary

The Liberian basin comprises offshore Liberia and Sierra Leone. Details of the regional structure and petroleum prospectivity of this frontier margin have not been well understood. In 2000-2001, TGS acquired 9,382 line km (5,715 line miles) of regional 2-D seismic data, and an interpretation report was released in 2007 and revised in 2010. Between 2007 and 2011, a series of 3-D seismic surveys was acquired over several blocks in the Liberian basin. All of these datasets have provided better understanding of the regional structure and petroleum prospectivity of this frontier margin.
