... Abstract China has abundant deep shale gas resources, but the complex problem of wellbore collapse in horizontal well drilling is prominent. Aiming at the problem of wellbore collapse in deep brittle shale, deep shale's mechanical loading simulation experiment scheme under a complex wellbore...

... Abstract Uniaxial compression tests and acoustic emission (AE) monitoring on shale specimens with horizontal bedding planes and perpendicular bedding planes after subjection to high temperatures (25°C, 100°C, 150°C and 200°C) were performed to investigate the effect of high-temperature...

... Abstract The development of deep shale gas reservoirs has become economically and commercially viable through novel horizontal well completion and multistage hydraulic fracturing technologies in recent years. In the Sichuan Basin, the deep Longmaxi shale is a major target formation that has...

... Abstract In recent years, the deep shale gas reservoirs has been a major shale gas target in Sichuan Basin. Usually, the burial depth of this target formation is more than 3500m, which is receiving increasing interests to get industrial natural gas. The deep shale gas reservoirs, characterized...

... Abstract In this study, uniaxial compression tests were conducted and acoustic emission monitoring technology was used on shales from the Liutang Village, Shizhu County, Chongqing City. The ringing count and energy evolution law during the compression process of shale samples were analyzed...

... Abstract This study investigated the transversely isotropic properties of water-bearing shale by performing laboratory experiments on shale specimens with different bedding angles of 0°, 45°, and 90° under different saturation conditions. X-ray diffraction, P-wave velocity, and water...

... of lost time and trouble cost. However, at present, the mechanism of the instability of the shale borehole wall is unclear. To study the shale WI in Wushi Oilfield, the rock mechanics parameters of rocks were tested according to the actual situation of the oilfield. Experimental results were helpful...

... Abstract The loading rate has a significant effect on the mechanical properties of shale and its influence degree is related to the angle of weak plane. Tri-axial compression tests were performed on shale samples from Longmaxi reservoir formation with GCTS RTR1500 mechanical testing system...

...Failure of Anisotropic Rocks such as Shales, and Implications for Borehole Stability R. W. Zimmerman, J. Ambrose, and N. B. Setiawan Imperial College, London, United Kingdom [email protected] Abstract In anisotropic rocks such as shale, the value of the maximum principal stress required...

... Abstract A tunnel in the region of Toronto, Canada, situated within the Georgian Bay shale and limestone formation, was simulated using the hybrid finite-discrete element method (FDEM). The model was calibrated based on input parameters that adequately reproduced standardized laboratory rock...

... ABSTRACT In this study, a method is devised to implement a supercritical CO 2 (scCO 2 ) injection environment on a laboratory scale and to investigate the effects of scCO 2 on the properties of rock specimens. Specimens of shale and sandstone normally constituting the cap rock and reservoir...

... of Disang & Barail of tertiary age. A major portion of HRT passes through a variety of rocks of sandstone with shale partings, intercalation of siltstone with shale and fine grained sandstone with dark grey shale. The project has witnessed a massive landslide on 1983, which resulted to a collapse of about...

... modelling. Based on the Brazilian Test [1] this paper analyses three types of rocks namely limestone, sandstone and shale, which belong to the sedimentary rock category with sandstone having greater strength than limestone and shale. The Finite Element-Discrete Element coupled method (FEM-DEM) used...

... Abstract When drilling wells through shales, the rock mechanics and physico-chemical properties of shales are critical to design the trajectory of wells, mud weight as well the mud chemical composition. In spite of their large occurrence, shales are also among the lesser known rocks...
