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.

New report: Multi-component kinetics and late gas potential, Cooper Basin

September 11, 2015

Geoscience Australia released in September a report on multi-component kinetics and late gas potential of selected Cooper Basin source rocks. The study, executed by GEOS4, evaluated twenty-seven whole rock samples and eleven extracted samples or kerogen concentrates from five potential Permian sources within the Cooper Basin, Australia for petroleum... More

Baltic-Paleozoic: New Regional Kinetics Package

July 21, 2015

This data package with key Lower Paleozoic Baltic Basin samples is based on 28 Cambrian, Ordovician and Silurian samples of variable maturity from Lithuania. Rock-Eval and pyrolysis gas chromatography data are provided for the whole sample set. Late Gas Potential was determined on eight of these samples. Full PhaseKinetics analysis on two selected... More

Norwegian Viking Graben regional source rock kinetics study released

May 4, 2015

This new PhaseFinder source rock kinetics Package addresses Draupne Formation source rock heterogeneity northwest and southwest of the Stord Basin. Major discoveries prove these areas as key exploration targets. Bulk and compositional kinetic data of 10 key immature source rocks assist in predicting the relative volumes of gaseous and liquid phases,... More
