Giant Oil Fields


http://www.africaoilcorp.com/i/pdf/Presentation.pdf


There are several large - in some cases, very large
undrilled structural closures in the Nogal Block. These
structures are big enough to contain giant oilfields.
Nogal-1 and Kalis-1 were well located exploration
boreholes. Neither well penetrated Jurassic sediments
but both encountered oil in the Cretaceous secondary
objective. The wells were logged but not tested due to
Conoco’s hasty withdrawal from the country in 1991.
Acquisition of a regional 2D seismic survey is required
to evaluate the prospectivity of the Darin Block
