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.

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

AAPG: Where the action was in 2014

February 6, 2015

2014 was a year with a healthy dose of modest petroleum discoveries, according to the January issue of the AAPG Explorer. It wasn’t a standout year, exploration appeared to represent “more of a return to normal, to more typical years” Julie Wilson, senior exploration analyst for Wood Mackenzie in Houston was quoted. Where was the action? More


Posidonia Shale Germany: database and regional synthesis updated

January 5, 2015

GEOS4´s database and regional synthesis of the Posidonia Shale in Germany has been updated to include the latest research, published and proprietary, on Germany´s world class source rock. First published in 2011, the updated data set includes latest results from basin modeling (20 new maps of maturity, dephts, thickness, and erosion; including onshore... More


Brian Horsfield on fluid retention behaviour, AOGC 2014

November 26, 2014

Brian Horsfield, CEO of GEOS4, presents new insights into HC-in-place and heterogeneity with reference to selected examples from Europe, the USA, China and Australia on the 18th Australian Organic Geochemistry Conference (AOGC). In his keynote speach he will lay out how these findings have changed our perceptions of fluid retention behaviour in... More
