Our Outlook is dominated by the uncertainty surrounding security. However, this is further undermined by the limited access to independent operators.

Description

North Africa originated as a north-facing passive continental margin until Late Carboniferous–Permian Hercynian compression reactivated the regional fault systems that segmented the passive margin into a mosaic of basins and uplifts. Silurian and Devonian source rocks were deposited during the passive-margin phase are preserved in the basins but were largely eroded from the uplifts during Hercynian compression. Variations in the magnitude of subsidence, uplift, and erosion among the basins led to temporal and spatial variations in thermal maturation of the source rocks. In some basins, gas is interpreted to have been generated prior to or during Hercynian compression, whereas in other basins, the source rocks reached the thermal window for oil or gas generation in the Mesozoic.

Summary

The GEAB basin in located onshore towards Algeria's interior. It is not widely explored by modern standards, principally due to the closed nature of the natural resources sector.
