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.

New screening tool for rapid identification of "sweet spots"

February 24, 2019

For the rapid and inexpensive identification of “sweet spots” or heterogeneities within vertical profiles, GEOS4 has developed a new geochemical screening tool. It is based on the evaluation of amount and composition of sorbed gas within source rocks using Thermovaporisation GC-FID. This can be easily run alongside Rock-Eval pyrolysis in high... More

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


Norway APA 2018: Timing of generation, GOR and phase behaviour

July 15, 2018

In the upcoming Awards in Predefined Areas (APA) 2018 licensing round, 47 blocks in the Norwegian Sea and 56 blocks in the Barents Sea have been defined. The application deadline for APA 2018 is 4 September 2018, and new production licenses are expected to be awarded during the first quarter of 2019.

New GEOS4 multiclient projects kick off

April 10, 2018

GEOS4 is proud to announce that all three new multiclient projects have attracted sponsors and started. However, projects are still open for additional sponsorship, so have a close look at the project outlines.  More
