Nanostructure Effect on Methane Adsorption Capacity of Shale with Type III Kerogen
, 2020 This study focuses on the nanostructure of shale samples with type III kerogen and its effect on methane adsorption capacity. The composition, pore size distribution, and methane adsorption capacities of 12 shale samples were analyzed by using the high ...

Separation and Artificial Maturation of Macerals from Type II Kerogen [PDF]
, 1997 Immature Type II kerogen (HI= 660 mg/g) from the Lower Toarcian of the Paris Basin was separated into an alginite concentrate (HI = 952 mg/g) and an amorphous organic matter (AOM) concentrate (HI = 573 mg/g) by density centrifugation.

Study of factors affecting shale gas adsorption by simplified local density-Peng–Robinson method
Energy Exploration & Exploitation, 2017 Shale gas has become an important source of natural gas, and a significant portion of gas in the reservoir exists in an adsorbed state. Thus, knowledge of gas adsorption behavior is important to estimate original gas in place and shale gas production. In

Surface Chemistry and Atomic-Scale Reconstruction of Kerogen-Silica Composites
, 2014 The interest in gas shale, a novel source rock of natural gas, has tremendously increased in recent years. Better understanding of the kerogen/rock interaction is of crucial importance for efficient gas extraction and hence for asset management.

Jump in the structure of Type I kerogen revealed from pyrolysis and 13C DP MAS NMR
, 2017 Artificial maturation of Maoming oil shale kerogen (Type I) was performed at a heating rate of 5 degrees C/h in a closed Au tube system. Yields of pyrolysis products (C1-5, C6-14, C14+ and insoluble residue) were quantified. The insoluble kerogen residue

Release of bound aliphatic biomarkers via hydropyrolysis from Type II kerogen at high maturity
, 2008 At relatively low maturity, kerogen-bound aliphatic biomarkers invariably display retardedmaturity compared to their ‘‘free” counterparts as a result of the protection afforded by themacromolecular structure.
