West Africa


ERCE has been involved in offshore West African work since the late 1990’s. ERCE has been the auditor of Tullow since 2003. We have worked with other core West African independent operators and have completed many prospectivity studies. We have also been involved with many of the major divestment processes by Shell, ConocoPhillips and Exxon across the regions. Our breadth of experience in Expert advisory, technical studies and CPR reporting, means that ERCE is a world leader in West African evaluations.
