GEOS4 research on oil and gas shales

July 7, 2019

GEOS4 staff has (co)authored several new research papers on oil and gas shales. A book chapter provides an overview of the chemical, physical, and biological processes involved in the formation of shale gas and shale oil and outline how organic geochemistry can be applied to the exploration and production of these resources. Read also about a joint... More


New GEOS4 research presented at URTeC 2019

May 15, 2019

GEOS4, in collaboration with petroleum industry companies, will present two research papers at the Unconventional Resources Technology Conference URTeC 2019, Denver, Colorado, 22-24 July.
We introduce PhaseSnapShots as a quick and low-cost tool for production efficiency assessments in the Permian Basin, US, and describe the effects of production... More


New screening tool for rapid identification of "sweet spots"

February 24, 2019

For the rapid and inexpensive identification of “sweet spots” or heterogeneities within vertical profiles, GEOS4 has developed a new geochemical screening tool. It is based on the evaluation of amount and composition of sorbed gas within source rocks using Thermovaporisation GC-FID. This can be easily run alongside Rock-Eval pyrolysis in high... More

Improve your Sichuan Basin shale gas predictions using analogues

October 7, 2018

Silurian shales, and most notably those of the Longmaxi Formation, are the prime target for shale gas exploration in the Sichuan Basin. They are highly overmature.

To reconstruct the timing of oil and gas generation in these shales, as well as documenting changing GOR and physical properties of petroleum during maturation, less mature comparable... More
