The Crustal Configuration and Deep Structures Related to the Pre-salt Oil/gas Objectives of the Eastern Maghreb: Need for Deep Seismic Imaging

Over the last decade, the major tectonic evolutionary steps of the Eastern Maghreb structures have been precisely constrained by shallow seismic Sects. (5 s TWT) interpretations and structural analyses. However, their overall configurations at depth, and their deep structural configuration controlled by the underlying basement, remain poorly understood because only few wells have succeeded to penetrate slightly deeper than the thick Triassic evaporites sequences in the Atlas and the foreland basins. Thus, this work focused on the deep structures affecting the Pan-African basement in the Eastern Maghreb by means of wide regional cross-sections passing through key structures of the Eastern Maghreb. Our purpose was to stimulate the exploration of deep hydrocarbon traps and stimulate the industry, universities, and other public research companies to launch a major research program on the deep crustal configuration in the Eastern Maghreb for the unlocking of deep oil/gas plays.
