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


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.

ShalePayFinder MENA-Silurian package released

December 9, 2013

The new ShalePayFinder package for Silurian source rocks from the MENA region has now been released for purchase.
This new package provides the relevant modelling input parameters for reconnaissance-level assessment of regional shale gas prospectivity. If you are targetting the Silurian shales in MENA for its unconventional (or conventional!)... More

Bakken Shale: Advances in Geochemistry, Migration Modelling, PhaseKinetics

October 28, 2013

The Bakken Shale is one of the largest unconventional oil plays in the U.S. Thousands of drilled wells provided insights for an improved understanding of the petroleum system, and the data from logs and rocks serve as input parameters for refined models. GEOS4 co-founder Rolando di Primio will present latest research results on the geochemical analysis... More

GEOS4 at Unconventionals Conference in Abu Dhabi

October 24, 2013

The conference "Unconventional Fossil Fuels: The Next Hydrocarbon Revolution?" will address, among others, implications of unconventional fuels for the oil-producing countries of the Arabian Gulf. This is timely, because when it comes to unconventional resource plays Middle East is a frontier exploration area. Governments are gearing up to unlock these... More
