GeoS4 profile

Built on the 40+ years combined experience of its co-founders, GeoS4 is a specialised service provider and consultancy to the upstream sector of the petroleum industry. We address exploration problems using cutting edge science, focussing on pre-drill pay definition.

There is no hype; there are no black boxes. We bridge the research-service divide, working with our customers via on-site placement and/or on-line networking. As a result, we can proudly boast a list of clients that includes some of the world's largest and smallest energy companies.

GeoS4 services

We use Petroleum Systems Modelling to integrate all the geological elements and processes that are fundamental to the evaluation of a petroleum system. This includes establishing the timing of petroleum generation from source rocks as compared to that of trap formation.

The PhaseKinetics approach allows the explorationist to link source rock organic facies to the petroleum type it generates. In a nutshell, we integrate organic matter structure and kinetics with Equations of State originally developed by petroleum engineers to predict petroleum composition ahead of drilling.

Our approach to gas shale profiling predicts high temperature methane generation, biogenic gas generation and nitrogen gas. For additional information on GFZ research programmes in this field, check out Gas Shales in Europe and Methane on the Move.

Research programme

Our specialised service know-how and activities are coupled with an aggressive and state-of-the-art research programme at GFZ German Research Centre for Geosciences in Potsdam, Germany. You can learn more about our IPP activities, including reservoir scale heterogeneities, biodegradation, phase prediction, deep gas, nitrogen and biogenic gas.

For more information on our research activities, read up on our current big projects Gas Shales in Europe (GASH) and Methane on the Move.

The bottom line

For the client, all of this translates into defining oil- versus gas-plays, identifying likely production problems and providing a prognosis of pipeline/transportation and refining costs.
