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.

Regional Kinetics offshore SW Africa: New dataset available

August 4, 2014

Use GEOS4´s compositional kinetics data set on Cretaceous source rocks for a refinement of prospectivity studies on the SW African shelf.

The data serve as input for petroleum system modeling studies to elucidate changes in the physical properties of petroleum fluids under varying pressure and temperature conditions. More


South-Eastern Barents Sea: New Regional Kinetics Package

June 16, 2014

GEOS4 is preparing a new regional kinetics data package for the South-eastern Barents Sea (Finnmark East). This area has seen exiting discoveries in recent years and is one of the core areas of interest in the 23rd licensing round in Norway. With our data you can quickly assign appropriate source rock properties to your petroleum system models when... More
