The evolution of porosity in shales with increasing maturity was examined in a suite of five
New Albany Shale samples spanning a maturity range from immature (vitrinite reflectance …

Hydrocarbon generation reactions occur within organic-rich shales as a response to thermal
maturation. Here, we report observations on samples from the organic-rich Mississippian …

Hydrocarbon generation and retention processes occurring within gas shales as a response
to increases in thermal maturation are still poorly constrained. While efforts have been …

Variations in the relative proportions of individual macerals in shales can significantly
influence the geochemical characteristics of bulk organic matter. Density fractions of …

Kerogen concentrates as well as whole rock samples of the Lower Jurassic Posidonia
Shale, representing a complete maturity series from immature to highly overmature, were …

Monoaromatic hydrocarbons (alkylbenzenes) in Paleozoic oils/condensates from the Tarim
Basin were quantitatively analyzed using gas chromatography–mass spectrometry. Their …

Low electrical resistivity measurements in organic-rich mudrocks are commonplace in highly
mature zones. These low resistivity values are usually difficult to justify and lead to …

This chapter describes shale gas resource systems in terms of their organic geochemical
characteristics. A key component in the volume of petroleum that can be generated is the …

Oil shale as well as shale oil and shale gas are significant energy resources with huge
reserves present in different parts of the world. Various geochemical proxies have been …

We integrated X-ray diffraction (XRD) data concerning the illite content in mixed-layer illite–
smectite with data derived from Fourier Transform Infrared spectroscopy (FTIR) on H-rich …
