Petrophysical lithofacies modeling of the upper Pennsylvanian Cline Shale in the Midland Basin, West Texas.
The Cline Shale is an upper Pennsylvanian interval of interstratified organic-rich shale, inorganic shale, and allochthonous carbonate beds, and is currently an active unconventional exploration target within the Midland Basin of west Texas. This study compares core-observed depositional facies to …

Petrophysical facies mapping of the Pennsylvanian Cline Shale, Midland Basin, West Texas.
The Cline Shale is a Pennsylvanian unconventional shale resource play located in the Midland Basin, west Texas. This study evaluates the depositional, stratigraphic and petrologic controls on Cline Shale reservoir quality and their spatial distribution as determined from core-calibrated …

Outcrop to subsurface stratigraphic analysis of the Juana Lopez member of the Mancos Shale, northwestern CO, U.S.A.
The Turonian Juana Lopez Member of the Mancos Shale in northwestern Colorado is a calcareous, bioclastic sandstone interbedded with organic-rich shale. Facies analysis of core and outcrops across northwestern Colorado indicates the presence of proximal, sand-prone facies to the north and distal, …

Creep properties of source rocks using indentation : the role of organic matter on texture and creep rates
Gas shale formations are source rocks of variable mineralogy with oil and natural gas production potential. Due to their low permeability, these source rocks can be produced only after fracturing. Therefore, understanding and characterizing the time-dependent mechanical properties of these …

Microporoelastic modeling of organic-rich shales
Due to their abundance, organic-rich shales are playing a critical role in re-defining the world's energy landscape leading to shifts in global geopolitics. However, technical challenges and environmental concerns continue to contribute to the slow growth of organic-rich shale exploration and …

Linear elastic fracture mechanics in anisotropic solids : application to fluid-driven crack propagation
… try to increase the permeability of gas shale rocks by fracturing it. In this context, we introduce some elements of linear elastic fracture mechanics in anisotropic solids. Notably, a special attention is paid to transverse isotropy, often used to model rocks but also some piezoelectric …

Application of Raman Spectroscopy and Transmission Spectroscopy for Shale Reservoir Characterization: Thermal Maturity Correlation and Organic Matter Type Differentiation
Organic rich shale formations have historically been of interest principally as source rocks for hydrocarbon (HC) generation. As such the prime areas of interest in their study have included organic matter type, as evaluated using geochemical techniques, and thermal maturity. The standard measures …

Geological Effects and Petrophysical Flow Unit Model for the Middle Bakken Member, South-East Saskatchewan
… and Sandstone Member layered between two black organic rich shale members. The Sandstone Member represents the major potential reservoir while the black carbonaceous shale acts as the source and the cap rock of the Bakken petroleum system. These shale rocks have also generated an enormous volume …

Characterization of anisotropy in organic-rich shales: shear and tensile failure, wave velocity, matrix and fracture permeability
Lamination and fractures are common features in organic-rich shales. The objective of this thesis is to determine the impact of lamination and fractures on elastic properties, shear and tensile failures, and the permeability of organic-rich shales. The elastic properties of rocks determine the …
