Nicolaj Mahlstedt presented at Gordon Research Conference
August 14, 2014
Nicolaj Mahlstedt, Petroleum System Analyst at GEOS4, gave a presentation at Gordon Research Conference on Organic Geochemistry, on tracing structural blocks of kerogen to HC and NSO-components in petroleum using a combination of pyrolysis methods and high resolution mass spectrometry (FT-ICR MS).

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
Think Molecular!
May 14, 2014
GEOS4 has published an article about basic concepts and major advantages of molecular kerogen analysis. Going beyond simple, routine Rock Eval typing schemes, we demonstrate by example that molecular characterisation does make a difference, and that it is the foundation of compositional kinetic modelling. Get a grip on new ideas and practical... More
New: GEOS4 Kinetics Database. Worldwide coverage, excellent quality
April 11, 2014
Our Kinetics Database contains activation energy distributions and single frequency factors for currently 193 samples worldwide. Use parameters you can rely on, linked to organofacies, for modelling source rock behaviour in conventional petroleum systems and the generation behaviour of tight lithologies in unconventional resource plays.
