Identification and Applications of Micro to Macroscale Shale Lithofacies
Journal of Nanoscience and Nanotechnology, 2021Systematic research and evaluations of shale gas reservoirs are critical in shale gas exploration and development. Previous studies in this field mainly depend on experimental analysis that is often overly simplified. Here, we report an integrated geological and engineering method that combines the lithofacies division system with an identification ...

Fuel, 2021 Nanopore structure development in shale is intimated with lithofacies that demonstrates a large variety in different formations. It is critical to differentiate and quantify the separate impact of lithological components (minerals and organic matter (OM))

Energy & Fuels, 2018
Total organic carbon (TOC), optical microscopy (OPM), field emission scanning electron mi-croscopy (FE-SEM), X-ray diffraction (XRD) and nitrogen gas adsorption (N2GA) analyses were performed on shale samples from the Upper Ordovician Wufeng Formation and the Lower Silurian Longmaxi Formation (Wufeng-Longmaxi Formation) in order to explore the effect ...

Proceedings of the 2nd Unconventional Resources Technology Conference, 2014
Organic-rich shale lithofacies, primarily defined by mineral composition and organic matter richness, reflects the features of the two critical factors for unconventional shale reservoirs. The research of shale lithofacies can aid in identifying shale gas productive zones and designing horizontal well and hydraulic fracturing.

Lithofacies of the Devonian Marcellus Shale In the Eastern Appalachian Basin, U.S.A.
Journal of Sedimentary Research, 2015The Marcellus Shale is an important hydrocarbon source rock and an unconventional reservoir whose origin has engendered much recent debate among geologists. Our analysis of the formation in West Virginia and adjacent States aims to identify and describe the several lithofacies in the eastern Appalachian basin and to interpret their depositional setting.

On the Zechstein Copper Shale lithofacies and palaeoenvironments in SW Poland
Geological Society, London, Special Publications, 1986Summary Microfacies and geochemical studies on the Copper Shale in the Sudetic Foreland of SW Poland show the strong influence of palaeorelief on the distribution of lithofacies. Spatial variability in microlithofacies and lithofacies indicate sedimentation in the following palaeoenvironments: (1) offshore—deep shelf, characterized by the ...

Lithofacies and Depositional Environments of Monterey Shale, California: ABSTRACT
AAPG Bulletin, 1981The Miocene Monterey Formation records the deep basinal phase of a major late Tertiary cycle of basin formation and filling associated with wrench fault tectonism. Over much of coastal California, Neogene facies show a progression from Oligocene nonmarine and neritic rocks to Miocene basinal shales and siliceous rocks and then to upper Miocene to ...

International Journal of Coal Geology, 2015
Abstract This study evaluates pore systems of the Horn River shale in Western Canada Sedimentary Basin from lithofacies classification of core samples to micro-scale pore structure investigation. Samples from the Middle and Upper Devonian Horn River shale sequence were examined by core description, porosity measurement, SEM, and TEM imaging of ion ...

Lithofacies classification in Barnett Shale using proximal support vector machines
SEG Technical Program Expanded Abstracts 2014, 2014Summary Classification of different lithofacies and petrotypes is one of the main objectives of modern quantitative seismic interpretation. In this study, we present preliminary results of the application of a proximal support vector machine (PSVM) classification algorithm to seismic data.
