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.

Improve your Sichuan Basin shale gas predictions using analogues

October 7, 2018

Silurian shales, and most notably those of the Longmaxi Formation, are the prime target for shale gas exploration in the Sichuan Basin. They are highly overmature.

To reconstruct the timing of oil and gas generation in these shales, as well as documenting changing GOR and physical properties of petroleum during maturation, less mature comparable... More
