During the last couple of years, drilling activities in the deepwater thrust belt play of Nigeria (Figure 1) have shown mixed results with some wells finding pay but others coming across low-saturation gas and/or brine sands. In this frontier exploration context, Shell Nigeria E&P Co. (SNEPCo) has been particularly successful in a number of toe-thrust prospects where the key risk is trap integrity, related to both earlier thrust faults and later extensional faults.
