Effects of pressure on the stable carbon isotope composition of gas generated from continental type-I and type-III kerogen under semi-closed conditions

Frontiers in Earth Science
Hydrous semi-closed pyrolysis was performed to clarify how water pressure (WP, 50–1,200 bar) and lithostatic pressure (LP, 125–2000 bar) control molecular composition and stable carbon isotopes of thermogenic gas from lacustrine Type I and Type III ...

Molecular Dynamics Study on CO2 Storage in Water-Filled Kerogen Nanopores in Shale Reservoirs: Effects of Kerogen Maturity and Pore Size [PDF]

, 2020
CO2 sequestration in shale reservoirs is an economically viable option to alleviate carbon emission. Kerogen, a major component in the organic matter in shale, is associated with a large number of nanopores, which might be filled with water. However, the

Correlative X‐Ray and Neutron Tomography of Microbial Biosignatures: Perspectives for Mars Sample Return

Earth and Space Science, Volume 13, Issue 7, July 2026.
Abstract Mars Sample Return (MSR) is the next major frontier in Mars exploration, through which advanced laboratory instrumentation will be used to study Martian samples and answer key questions surrounding Mars' planetary evolution and astrobiology. Non‐destructive, high‐resolution imaging will be critical for preliminary MSR analyses.

Surface Chemistry and Atomic-Scale Reconstruction of Kerogen–Silica Composites

, 2018
Interest in gas shale, a novel source rock of natural gas, has increased tremendously in recent years. Better understanding of the kerogen-rock interaction is of crucial importance for efficient gas extraction and, hence, asset management. In this study,

Seismic characterization of kerogen maturity: An example from Bakken shale

, 2020
Summary The conversion of kerogen to oil/gas will build up overpressure. Overpressure is caused by conversion of solid kerogen to fluid hydrocarbons in a relatively fixed pore space.
