Abstract
This paper presents a case study outlining key technical developments and the integration of geophysical and geological models that have advanced our understanding of the hydrocarbon plumbing in the Agbada Formation in the Rio del Rey Basin, offshore Cameroon. Geophysical techniques including extended elastic impedance and seismic fluid classification were developed using elastic log data and modern 3D seismic data. These techniques were shown through the drilling of the Oak wells to aid the prediction of presence and hydrocarbon phase in exploration targets. Gas composition analysis in the wells combined with seismic interpretation has resulted in an understanding of how the different oil and gas reservoirs have been sourced. Integrating the geophysical and geological models means there is a coherent approach to de-risk the presence and phase of hydrocarbons in the prospects.
