ABSTRACT: 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.
