Geological Drivers for Reprocessing

The presence of an active hydrocarbon system in the Douala/Kribi-Campo Basin has been demonstrated by numerous gas and oil discoveries both onshore and offshore. Regional PSDM reprocessing of 3D seismic datasets will significantly improve imaging of the deeper plays in the basin including Cretaceous basin-floor fans and compound channel systems. Previous work along the margin has shown the importance of accurate well placement, particularly when targeting channels; GeoSpec’s 3D TerraCubePSDM project will better define these stratigraphic and combination traps, taking lateral velocity variations into account. Instant comparisons between blocks will be possible using the single continuous dataset and the associated consistent gathers, stacks and sub stacks.

This 3D TerraCubePSDM dataset will be large enough to provide regional context, yet focused enough to image subtle changes.

Specific workflows for the project included broadband processing technology, advanced de-multiple algorithms, detailed velocity model building and improved imaging driven by the various geological and geophysical issues within each of the currently open blocks. Key challenges include removal of ringing within legacy data in the Tilapia block, which obscures the proven Paleocene play where oil was produced from Coco Marine-1, and amplitude dimming and incorrectly focused reflectors within the Ntem block.

Available now: Cameroon enhanced data packages - available exclusively from CGG

TerraCube Geomodel

In partnership with SNH, GeoSpec are pleased to make available workstation-ready exploration packages including enhanced 3D, 2D and well data for the Douala/Kribi-Campo and Rio del Rey basins sedimentary basins of Cameroon.

Following the successful conclusion of the 2018 Cameroon onshore and offshore License Round, we are pleased to announce that until further notice bona-fide E&P companies may approach SNH directly for 1:1 negotiations on any remaining available exploration blocks. Once initiated, negotiations will be expected to progress in a timely manner, prior to the opening of the 2020/21 licensing round.

Cameroon Prospectivity Overview


Cameroon currently produces hyrdrocarbons from its two main basins: Rio del Rey (since 1977) and Douala/Kribi-Campo since the late nineties. Oil production reached 8.1mmbo in 2019 but output has been in steady decline since the mid 1980’s. Cameroon are offering attractive terms to their flexible 2019 Petroleum Code to continue to entice international oil companies back to the region. An effort to promote exploration, thus reversing the decline in production.

Cameroon is a proven hydrocarbon province with production from both the Rio Del Rey and Douala/Kribi-Campo basins. Significant further opportunities exist for commercial hydrocarbon accumulations in both basins with large tracts of open acreage available , particularly in the Douala/Kribi-Campo basin, that could offer one or more companies a significant strategic position.

Cameroon interp To the south of the Cameroon volcanic line, the Douala/Kribi-Campo basin, with several large blocks available in the round, is located at the northern end of the prolific hydrocarbon producing South Atlantic Rift. Both pre- and post-Campanian source rocks are proven, producing liquid hydrocarbons as well as gas/condensate. Structural and stratigraphic traps are proven from Early Cretaceous through to late Tertiary, varying from tilted fault blocks to turbidite channels and fans in deeper water. Recent new petrophysical and geophysical analysis has identified potential missed opportunities from previous exploration, as well as new plays with the potential for large volumes of hydrocarbons to be present across this increasingly prospective basin.

Cameroon play cartoon

To the north of the Cameroon volcanic line lies the prolific Rio Del Rey basin, which is the easternmost extension of the Niger Delta complex and currently produces from the classic play of the Agbada Formation deltaic sands. The under-explored deeper intervals of the Isongo, Oongue and Nguti sandy turbidites mainly enveloped within the undercompacted shales of the Akata Formation have been tested with discoveries and contain significant undiscovered resources. The tested discoveries of the Isongo turbidites in Cameroon are currently being appraised for production and lie on the same fairway as the gas/condensate reservoirs in the Alba Complex field. The Diongo sands have been confirmed to have additional resources.
