Conventionals

We address all elements of petroleum systems through geochemical analysis and basin modelling. We specialise in pre-drill petroleum properties prediction.

Unconventionals

Our expertise helps you to address the three main stages of unconventional petroleum exploration and production, from regional reconnaissance through reservoir profiling to development.

Kinetics Database

Use parameters you can rely on for modelling source rock behaviour in conventional petroleum systems and the generation behaviour of tight lithologies in unconventional resource plays.

Algeria and Libya Petroleum System Modelling Studies

March 7, 2016

GEOS4 offers two new 2D Petroleum System Modelling studies, covering transects of the Berkine/Ghadames Basin in eastern Algeria and the Jabal Nafusah Area, NW Libya. The models are based on the main source rocks in these areas: the `hot shales` of the Silurian Tanezzuft Formation and the Frasnian shales. Geological evolution, source rock maturity and the... More
