We have also worked with clients in the modelling of cyclic steam stimulation and steamflood for heavy oil assets with our alliance Unconventional expert, GLJ.

ERCE Directors were appointed by the UK government in the 1980’s to produce the independent Geophysical and Engineering reports for the privatisation of the UK Energy Sector. Building on that foundation, ERCE has worked on virtually every oil and gas field in the United Kingdom, at some point in time.

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.
