“…Bouguer maps of the Douala sub-basin are characterized by high positive anomalies which suggest the possibility of continuity beyond the South-West coastal portions. 3D surface oriented plots in the Douala sub-basin further emphasize this possible extension (Ndikum et al, 2019a…”

“…Malquaire et al (2017) carried out 3D gravity modeling in the northern part of the Kribi-Campo sub-basin to indicate the presence of a dense intrusive igneous body of density 2.74 g/cm 3 in the upper crust. Ndikum et al (2019aNdikum et al ( , 2019b have also employed geophysical techniques of Euler 3Ddeconvolution, Source Edge Detection (SED), analysis of some special functions (horizontal gradient magnitude (HGM), analytic signal (AS) and the local wavenumber (LW)), 3D surface oriented models and 3D voxel solutions to characterise a 3D intrusive body and other structural lineaments in the Douala sub-basin.…”

The Gulf of Guinea constitutes an area of great petroleum potential yet with very limited geophysical research information. Consequently in this study, a Bouguer anomaly map has been computed from gravity data covering regions stretching from the Cameroon coastal basins to Bioko island (formerly Fernando Po) which is part of Equatorial Guinea. The data were further processed for Source Edge Detection (SED), Euler 3D deconvolution, 3D surface oriented models and 3D voxel solutions. The results confirmed the presence of previously identified intrusive bodies around the Douala and Kribi/Campo sedimentary sub-basins and went ahead to suggest a probable continuity between these two. A possible extension of this body offshore the Gulf of Guinea right up to Bioko island with very striking similarities was also highlighted and it shows characteristic variations in the depth to the surface of the body at different locations.
