Mesozoic marine organic-rich shales

Geological Society, London, Special Publications, 1987
Summary A survey of Mesozoic organic-rich shales in space and time indicates that they are widely distributed through much of the era but are concentrated especially at two levels: Upper Jurassic (Kimmeridgian-Volgian/Tithonian) and Middle Cretaceous (Aptian-Turonian).

Introduction to special section: Organic-rich shales

Interpretation, 2015
Successful exploration and production programs for organic-rich shales depend significantly on the kerogen characterization, i.e., identification of kerogen content estimation of its maturity, and prediction of kerogen with different methods.

A Compositional Model for CO2 Storage in Deformable Organic-rich Shales

Proceedings, 2017
Abstract Increased development of resource shales near industrial areas is spawning interests in storing CO2 generated from the neighboring industries in depleted organic-rich resource shales. This work presents a compositional model for the flow of a multi-component hydrocarbon gas and CO2 in a deformable porous medium consisting of an ...

Compositional Reservoir-Flow Simulation for Organic-Rich Gas Shale

SPE Journal, 2017
Summary A new-generation compositional reservoir-flow-simulation model is presented for gas-bearing organic-rich source rocks, including convective/diffusive mass-balance equations for each hydrocarbon component in the organic (kerogen), inorganic, and fracture continua.

Factors controlling organic-matter accumulation in the Upper Ordovician-Lower Silurian organic-rich shale on the northeast margin of the Upper Yangtze platform: Evidence from petrographic and geochemical proxies

Marine and Petroleum Geology, 2020
Organic-rich shales are widespread in the Upper Ordovician-Lower Silurian Wufeng-Longmaxi Formations on the northeastern margin of the Upper Yangtze platform, and these shales have been recognized to be the hydrocarbon source rocks and shale gas ...

Generation of Oil-Like Pyrolyzates from Organic-Rich Shales

Science, 1979
Pyrolyzates similar to natural crude oils were generated from organic-rich shales by hydrous pyrolysis. With this type of pyrolysis it is possible to make more sophisticated correlations between crude oils and their source rocks, evaluate the hydrocarbon potential of a source rock, and elucidate the variables involved in the natural oil-generating ...

Experimental investigation of thermal expansion of organic-rich shales

International Journal of Rock Mechanics and Mining Sciences, 2020
Abstract Experimental data on thermal expansion of rocks are necessary for many applications involving wellbore stability analysis, designing radioactive waste repositories, etc. Such information is especially actual for organic-rich shales that exhibits significant thermal anisotropy and heterogeneity and were not studied comprehensively previously.

Comparison of geochemical characteristics of marine facies, marine-continental transitional facies and continental facies shale in typical areas of China and their control over organic-rich shale

Energy Sources, Part A: Recovery, Utilization, and Environmental Effects, 2020
The geochemical characteristics of marine, marine-continental transitional, and continental facies shale and their control over organic-rich shale were discussed. Results showed that the TOC content of marine shale was the highest with an average of 4.95%

Modeling of Methane Adsorption on Organic–Rich Shales

78th EAGE Conference and Exhibition 2016, 2016
Recovery of gas from organic–rich shales has become a focus for resource development worldwide. Excess adsorption isotherms of methane at 35℃, 50℃, and 65℃ and pressure up to 12 MPa were measured on Lower Cambrian shales from Sichuan Basin of China. Classic adsorption models (Langmuir, Freundlich, and Dubinin–Astakhov equations) had been applied to ...

Porosity-Deformation Relationships in Organic-Rich Shale

2019
Abstract Shales exhibit a wide range of textures, compositions, and mechanical properties, which are interlinked by their diagenetic history. During hydraulic fracturing of shales, the matrix is subjected to shear deformation, which may create microfractures and enhance hydrocarbon transport from nanoscale, organic matter (OM)-hosted pores to the ...
