This Regional Report examines the petroleum systems of the interior basins of the Algerian Saharan Platform. The report evaluates the tectonostratigraphic evolution of the basins on the northern edge of the African Craton in Algeria and the key issues of source, reservoir and seal development and maturation history.
The report builds on Getech’s unique global gravity and magnetic data to underpin a re-evaluation of the structural development of the Saharan Platform in Algeria. This forms the basis for an evaluation of the tectonostratigraphy of key horizons in the study area.
The report also incorporates tectonics, petroleum systems, palaeodrainage analysis and play fairway mapping, with a particular emphasis on establishing the evolution of the Algerian Saharan Platform through the Paleozoic and Mesozoic supercycles. Particular emphasis has been given to specific issues surrounding source and reservoir distribution and quality, source maturation history, seal distribution and competency, and trap formation; all these have been used to generate new insights into the petroleum systems of the Algerian Saharan Platform.

This Regional Report investigates…
…how Hercynian and Post-Hercynian movements have affected petroleum systems.
…the influence of the intra-basin highs on sediment source and transport pathways.
…how the proximity to land has influenced the distribution and quality of source and reservoir rocks.
…the hinterland extent of the Paleozoic and Mesozoic supercycles onto the Saharan Platform.
…the importance of glacial valleys in the distribution of Silurian source rocks.
…the influence of Triassic volcanics on source maturity across the Saharan Platform.
…if sequence stratigraphic analysis can assist in understanding the distribution of potential play fairways in frontier areas.
…movement on the main structural lineaments and its affect on the competency of seals, trap formation and hydrocarbon migration.
