Post-Rift Potential Source Rock Correlations and Prospectivity of the Deep Atlantic Conjugate Margins, South of the Walvis Ridge
The deposition of this source rock is interpreted to be widespread in the deep water and modelled to be oil mature in several large kitchen areas, situated in present day water depths from <500m to over 3000m. Additionally, good quality Cenomanian to Santonian age source rocks have also been identified in several wells offshore Namibia, such as the 1911/15-1 well with TOC levels reaching up to 10 % and a gross thickness of 170m, and the Kabeljou-1 well with average TOC of 5.3% and approximately 50m thickness.
The Barremian to Aptian age source rocks on the Namibian margin are now recognised to be the principal source rock for future exploration drilling and they are characterised by parallel-bedded, low amplitude, low frequency, continuous low-impedance reflectors, which lie above the SDRs. The Aptian section above the SDRs in the deepwater (>2 km) Pelotas-Argentine margin has never been drilled, but seismic data indicates a similar stratal package. Recent 2D/3D seismic data from Namibia will be used to characterise the source rock package and compare with recently acquired seismic from Argentina and Uruguay.
