We are consultants to the fossil energy sector. We provide petroleum system assessments using tailormade compositional kinetic models, a global kinetics database, bound biomarkers and polar compound tracing.
Brian Horsfield will deliver a keynote address at the EAGE Workshop on Petroleum Geochemistry in Operations and Production,which will be held in Doha, Qatar 3-5 October 2016. More
The new Midland Basin Hydrocarbon Phase Study is now open for sponsorship. This joint venture of GeoMark and GEOS4 focuses on predicting the GOR and PVT properties of dispersed petroleum in the Wolfcamp, Spraberry and Cline Formations. More
GEOS4's Mareike Noah successfully completed her Ph.D defence at the Technical University of Berlin, 28 June. Her thesis is entitled ”Biogeochemical Process Studies on Oil Sand Tailings used for Land Reclamation in Alberta, Canada”, and utilises FT-ICR MS as a tool for examining polar compounds in highly altered oils.

GEOS4 offers two new 2D Petroleum System Modelling studies, covering transects of the Berkine/Ghadames Basin in eastern Algeria and the Jabal Nafusah Area, NW Libya. The models are based on the main source rocks in these areas: the `hot shales` of the Silurian Tanezzuft Formation and the Frasnian shales. Geological evolution, source rock maturity and the... More
Brian Horsfield, CEO of GEOS4, will present an invited keynote at the 21st International Symposium on Analytical and Applied Pyrolysis which will be held 9-12 May 2016 in Nancy, France.
The title of his presentation is: "Geochemical transformation and transport processes as revealed by kinetic determinations and molecular indicators". More
