Tindouf

Commentary

Exploration of the TDFB is constrained by security risk near the Western Sahara border and limited access for independents. Improved fiscal terms and bid rounds are positives but do not offset these constraints. Outlook: Uncertain.

Description

The TDFB is the westernmost of a series of Palaeozoic intracontinental basins that are present across much of northern Africa. North Africa was a passive margin in the lower Palaeozoic with fluvial systems flowing northwards towards the ocean. Glaciation across North Africa waned in the Ordovician, with meltwater forming a series of north-trending incised valleys that were filled with organic-rich sediments during a major south-directed transgression in the Silurian. Another major transgression in the Late Devonian led to deposition of a second layer of organic-rich shale.

Summary

The TDFB straddles the borders with Morocco and the SADR, which has meant that exploration has been relatively limited.
