TGS, APPA move to standardize basin references offshore West Africa

Offshore staff

ASKER, Norway – TGS and the African Petroleum Producers’ Association (APPA) have signed a letter of intent to “harmonize the stratigraphic nomenclature of the sedimentary basins of 13 countries in Africa.”

The project is intended to provide a standard and consistent framework for future exploration of these basins, contributing to a reduction of the exploration risks and an improvement of productivity.

The project will use TGS’ skills in sequence stratigraphy and seismic interpretation to create new stratigraphic columns for each basin and country. The project will extend the interpretation to include gross depositional environment mapping, seismic facies analysis, and play fairway analysis over time. The results will be primarily delivered using TGS’ proprietary Facies Map Browser.

The project will incorporate data from more than 1,300 wells and 200,000 km (124,274 mi) of 2D seismic. The countries concerned cover from the Republic of Cote d’Ivoire to Angola. Each of the 13 countries involved is committed to using the new stratigraphic nomenclature in all future exploration work.

It is anticipated that the new nomenclature will be complete by end 2018 with the additional studies completed thereafter.

The project, anticipated to start in January 2016, is currently seeking further industry support.
