GEOS4 staff has (co)authored several new research papers on oil and gas shales.
Oil and Gas Shales
This 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.

Oil retention and intrasource migration in the organic-rich lacustrine Chang 7 Shale of the Upper Triassic Yanchang Formation, Ordos Basin, Central China
In a joint study with PetroChina, this paper presents the reservoir scale variability in composition of Mesozoic shales from China, Ordos Basin.

Compositional fractionation of petroleum from reservoir to wellhead in the Niobrara shale oil play
In a joint study with Noble Energy, this paper shows how the FT-ICR MS method employed by GEOS4 is a key tool in deciphering fractionation during production from shale.
