Jan 1, 2023 · The sedimentary environment governs the depositional processes, ecological environments, and hydrodynamics, which affect the accumulation of organic-rich sediments.Some particular issues are unsolved about the organic matter accumulations of lacustrine shale mixed with shell bioclasts due to their alternating deposition. Jun 1, 2014 · This paper presents the historical context and current state of shale gas development in Canada (Section 2), geological contexts of main Canadian shale plays containing dry gas (Section 3), facts on hydraulic fracturing (Section 4), water usage by this industry (Section 5), as well as various research initiatives implemented to investigate different environmental issues mentioned above and to ... The high temperature and high in-situ stress geological environment can significantly affect the mechanical properties, failure modes, and deformation characteristics of deep shale reservoirs. In this study, real-time high temperature triaxial compressive tests simulating the deep shale formation environment (temperature: 25–150 °C, confining pressure: 0–100 MPa) are carried out. The GSI ...
