The French major is racking up barrels of deepwater production as part of its large-scale West African push. Despite a trend toward renewables and low-carbon energy production among European majors, Total remains wholeheartedly committed to deepwater production. West Africa has seen a significant shift in drilling activity, mainly in deep water. Many of the major international operators are carrying out important exploration-and-development activities there. The subject field in deep water off West Africa provides an opportunity to perform a review of how well the reservoir-performance predictions made at project funding matched with the final actual field performance.
