Liberian Basin - When the Atlantic opened rivers from the interior (St. Paul, Cestos, Cavalla and Lofa) flowed to the Liberian coast depositing a thick series of sediments into the Liberian basin.

The Harper Basin - The most recent available area is the hardly explored Harper Basin in the southeast offshore sandwiched between the Liberian and Ivorian Basins within the St. Paul Transform System. Syn-rift structural traps can be identified over much of this area, which offer multi-level prospectivity, with analogues to producing fields in neighbouring basins.

Modelling predicts source rock maturity and expulsion post-dates the main tectonism in the basin, and seal presence is evident in West African Transform Margin analogues. Also, several regional channel and fan complexes have been mapped in the Upper Cretaceous and across the shelf, slope and into the deep basin some of which cover over 300 square kms. Volumetric assessment of these features suggests large field sizes could be present.

History

In development

Hydrocarbon exploration began offshore in Liberia basin in the 1940s on the shelf. This had no success and exploration ceased until 2000 when TGS-NOPEC, directed by the newly formed National Oil Company (NOCAL), began the acquisition of 2D seismic data. This confirmed some potential for oil-bearing structures in deep water areas up to 3000m. With the installation of a transitional government in 2003, NOCAL proceeded with a licensing round modelled after the Sierra Leone round. Four offshore blocks were awarded to 3 companies.
