Gas evolution during kerogen pyrolysis of Estonian Kukersite shale in confined gold tube system

, 2013
Pyrolysis of Kukersite kerogen was conducted in gold capsules, with the yield and stable carbon isotopic (d13C) values of selected gas components (C1, C2, C3, i-C4, n-C4, i-C5, n-C5, CO2) and liquid hydrocarbons (C6-C14) separately measured to ...

Impact of Composition on Natural Gas Desorption from Kerogen

, 2018
Shale gas reservoirs hold adsorbed gas in kerogen. Laboratory techniques have been developed to measure the gas amount in samples. However, adsorbed gas recovery is an unsettled issue.

Effect of Temperature on Kerogen Transformation and Hydrocarbon Generation in Bazhenov Formation (Western Siberia, Russia) Rocks During Hydrous Pyrolysis

Energies
The aim of this investigation is to determine the role of temperature in hydrocarbon generation in Bazhenov formation source rocks, as hydrothermal processes in situ are supposed to be the main contributor to kerogen transformation in Western Siberia ...

Molecular Dynamics Simulation Study on the Occurrence of Shale Oil in Hybrid Nanopores

Molecules
The molecular dynamics simulation was used to simulate the influence of the composite wall stacking effect on shale oil occurrence. The kerogen-illite heterogeneous wall pore model was established to study the effects of temperature, pore size, and wall ...

The Cretaceous-Tertiary boundary Fiskeler at Stevns Klint, Denmark: the geochemistry of the major trace metals [PDF]

Journal of the Serbian Chemical Society, 2001
Trace metals in the four discrete layers of the Cretaceous-Tertiary boundary (Fiskeler) at Stevns Klint (Denmark) are relatively well studied, yet much remains to be learned about them.

Multistage alkaline permanganate degradation of a type-III kerogen

, 1985
In order to obtain evidence on the relationship between kerogen structural types and the quantity and nature of their oxidation products, the products of a multistage (13 step) alkaline permanganate degradation of type-III kerogen from a sample of the ...

Methane Adsorption and Self-Diffusion in Shale Kerogen and Slit Nanopores by Molecular Simulations

, 2018
Shale gas has redefined the energy landscape in the world. The scientific community makes efforts to exploit shale gas resources with minimum environmental impact. Shale gas is mainly located in micropores and mesopores of shale rocks.

Effect of Microstructural Flexibility on Methane Flow in Kerogen Matrix by Molecular Dynamics Simulations

, 2019
We investigate the flow of methane in a kerogen matrix with microstructural flexibilities at various pressures. The matrix is constructed by compressing a collection of 60 type II kerogen macromolecules.

Thermodynamic Modeling of the Equilibrium Partitioning of Hydrocarbons in Nanoporous Kerogen Particles

, 2019
In unconventional shale, petroleum compounds are generated during kerogen maturation and chemical fractionation occurs between fluids that are expelled out of kerogen and retained within kerogen because of different solubilities of hydrocarbons in ...
