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.

Controls on petroleum storage in shales: “Porosity makes the difference”

June 22, 2017

GEOS4 staff has co-authored a research paper showing that while the amount of petroleum retained in shales is a function of total organic carbon (TOC) content as well as chemical structure of the macromolecular organic matter, porosity is the fundamental control of how much recoverable oil can be stored. More
