PetroStrat geoscientists have a wealth of experience in the provision of integrated bio-stratigraphic and multi-well sequence stratigraphic services throughout the West and South African margins. This includes Tertiary and the Cretaceous sediments, the post-Salt and the pre-Salt.
PetroStrat have developed a high-resolution composite bio-zonation scheme for the Tertiary and Cretaceous strata found along the West African Atlantic margin. This advanced, integrated scheme incorporates bio-events derived from all three biostratigraphic disciplines, allowing for a more accurate correlation of stratigraphy across the region. This zonation is calibrated to the published zonation schemes and, in the post-Salt marine sections, to the sequence chrono-stratigraphic frameworks of Gradstein et al.
