In January 2018, Sasol acquired a 40% interest of the Block DE8 from Perenco.Â Perenco retains the remaining 60%. DE8 exploration permit is located along the coast off Omboue, 90-190km SSE of Port Gentil, in water depths ranging from 0 to 80m. Straddling the limit between the North and South Gabon sub-basins, DE8 surrounds three fields operated by Perenco Oil Gabon Ltd, Tchatamba Marin, Tchatamba West and Tchatamba South. Potential reservoirs in the area are the Albian Upper Madiela unit, which is the main reservoir on the Tchatamba complex, and the Senonian Batanga Formation. Potential source rocks lie in the Turonian Azile and Albian Madiela formations.
