Review on the kerogen deformation mechanism [PDF]

E3S Web of Conferences, 2022
Shale gas is unconventional natural gas energy stored in shale, and is one of the important substitutes for conventional oil and gas resources. Since amorphous kerogen is the main component of shale organic matter and has a high degree of deformation ...

The kerogen vanadyl porphyrins: incorporation during catagenesis [PDF]

Journal of the Serbian Chemical Society, 1999
Natural vanadyl (VO2+)-deoxophylloerythroetioporphyrins (DPEP) have been shown to be capable of reacting and quantitatively incorporating into immature kerogen model materials (torbanite, lignites, subbituminous coal and immature lacustrine kerogen) at ...

Primary research on expression of kerogen in Longmaxi Shale and its adsorption characteristics [PDF]

Youqicang pingjia yu kaifa, 2023
Adsorbed gas represents a primary mode of shale gas occurrence and is a major source of shale gas production in the later stages of development. It primarily resides within the organic kerogen and clay minerals of shale formations, with organic kerogen ...

Effect of Kerogen Thermal Maturity on Methane Adsorption Capacity: A Molecular Modeling Approach

Molecules, 2020
The presence of kerogen in source rocks gives rise to a plethora of potential gas storage mechanisms. Proper estimation of the gas reserve requires knowledge of the quantities of free and adsorbed gas in rock pores and kerogen.

Multiscale Reconstructions, Effective Elastic Properties, and Ultrasonic Responses of Kerogen Matter Based on Digital Organic Shales

IEEE Access, 2021
Organic shales usually present significant heterogeneities in rock textures and reservoir properties due to differing kerogen contents and morphologies, subsequently impacting shale elastic properties and acoustic responses.

Stress distribution around kerogen particles as a measure of the initiation of bitumen-filled microfractures in organic-rich source rocks

MethodsX, 2022
: In this article, we present a method used to model the initiation of bitumen-filled microfractures in immature, organic-rich source rocks. The first part presents the method used to calculate the stress distribution around the kerogen particles.
