ABSTRACT: In order to produce a more detailed structural and geometrical information,
and determine sediments thickness along the Kribi-Campo sub-basin, statistical
spectral analysis and horizontal gradient analysis of residual anomalies coupled
with the Euler deconvolution approach were applied on the gravity data in the
area. The results obtained from the 2D spectral analysis on anomaly grids gave a
depth to the basement rocks of the basin from 0.60 km to 3.93 km. This
represents the thickness of the sedimentary formations overlying the basement.
The interpretation of the spectral analysis results indicated that the potential
hydrocarbon field areas are situated between Kribi and Lolabe and at Campo
given that those areas have the highest sedimentary thicknesses values. From the
analysis of the horizontal gradient, deep faults mainly striking SW-NE have
been traced and a structural map of the area has been produced. By applying the
Euler deconvolution method to the gravity data, information about the depth
and trend of the main subsurface structures have been obtained.
