Mesozoic marine organic-rich shales
Geological Society, London, Special Publications, 1987Summary 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, 2015Successful 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.

Generation of Oil-Like Pyrolyzates from Organic-Rich Shales
Science, 1979Pyrolyzates 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, 2020Abstract 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.

Modeling of Methane Adsorption on Organic–Rich Shales
78th EAGE Conference and Exhibition 2016, 2016Recovery 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 ...

A Compositional Model for CO2 Storage in Deformable Organic-rich Shales
Proceedings, 2017Abstract 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, 2017Summary 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.

Porosity-Deformation Relationships in Organic-Rich Shale
2019Abstract 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 ...

A New Geochemical Tool for the Assessment of Organic-Rich Shales
Unconventional Resources Technology Conference, Denver, Colorado, 12-14 August 2013, 2013Summary Here we present a recently developed pyrolysis technique called LIPS (Laser Induced Pyrolysis System) that can be used for a high-resolution definition of total organic carbon (TOC) contents in core samples. Typically, LIPS measurements are performed on a centimeter scale, and hence, the syste m collects roughly 10,000 TOC values on a 100 meter

The Maturity of Organic-Rich Shales Using Microimpedance Analysis
SPE Annual Technical Conference and Exhibition, 2010Abstract The increasing importance of organic-rich shales, ORS as hydrocarbon reservoir rocks has lead to a demand for better understanding of the processes that lead to shale maturity. An improved understanding of these processes in the laboratory can lead to development of methods for their indirect geophysical detection at in-situ ...
