Damn vanwinkle23. You burst my bubble. I thought 3rd was the CEO of an oil company with 30 years of experience drilling wells. Who are you, fahraint? Neither of you have ag tags. I think fahraint got banned about the same time you created your account. Interesting coincidence.

The geology is different for a variety of reasons but most importantly is the one that there did not exist offshore Sierra Leone a body continental shelf landmass like offshore Guinea. Any source rock basin that existed offshore Sierra Leone and Liberia still exists there today. In contrast, offshore Guinea there was the continental shelf land mass called the Demerara Plateau
To continue, in contrast here, Guinea offshore area has this major GFZ (Guinea Fracture Zone) which acts as the boundary between essentially the North Atlantic Geologic Province and that of the South Atlantic Geologic Province. This GFZ is the major transform fault positioned orthogonally to and intersecting with the continental landmass known as Guinea today. The GFZ northern half sets in the north of our concesion and the southern half was at one time attached to the south. It is this portion that got "rafted" away with the breakup of the Pangea super-continent known in circles of Plate Tectonics. The GFZ is a tranpressional fault (you can look up this term in any structural geology text or advanced one for explanation in compressional tectonics (there are two types of tectonics, one compressional and one extensional).
Sierra Leone and Liberia never had this setup. Thus, when the breakup occurred between South America and Africa, the southern portion of the Demerara Plateau was essentially broken at this junction of the GFZ. As the continental shelf breakup occurred, the portion that would have contained the source rock basins (or many mini-basins) rode on the South AMerican Plate leaving the area south of the GFZ essentially devoid of any possible source rock basin (or basins collectively).
