An investigation was conducted to study the reutilization of clear fracturing flowback fluids composed of viscoelastic surfactants (VES) with additives in surfactant flooding, making the process more efficient and cost-effective. The clear fracturing flowback fluids were used as surfactant flooding system with the addition of α-olefin sulfonate (AOS) for enhanced oil recovery (EOR). The interfa...

The AOC Granite 7-32-89-10 hole, drilled to search for oil in the Precambrian basement below the Alberta bituminous (tar) sands near Fort McMurray, Canada, penetrates layered biotite-hypersthene quartz diorite-gabbro sills that occur between 543 and 2363.3 meters depth. Three episodes of fracturing and cataclasis affected these sills. The first allowed Kand Si-metasomatism to change many parts ...

The first step was to collect, process, and examine the data from SHEBA. The meteorological data include wind speed, air temperature, and longwave and shortwave radiation. Ice core data were used to calculate an average profile of ice salinity and porosity. Snow cover variations were combined into bins to produce a time history of the fractional coverage of snow as a function of time. Ice stres...

Considerable fracturing occurs around the deep mine stopes because of the mining induced stresses superimposed on the high overburden stresses encountered at these depths. The frequency and orientation of fracturing is largely affected by the presence of geological structures, as well as the stope layout and mining configurations. Being able to accurately predict the effect of these interfaces ...

Abstract The occurrence of disasters in deep mining engineering has been confirmed to be closely related the external dynamic disturbances and geological discontinuities. Thus, a combined finite-element method was employed simulate failure process an underground cavern, which provided insights into mechanism hard rock affected by factors such as stress-wave amplitudes, disturbance direction, di...

The large-deformation mechanics and multiphysics of continuous or fracturing partially saturated porous media under static dynamic loads are significant in engineering science. This article is devoted to a computational coupled periporomechanics paradigm assuming passive air pressure for modeling failure variably media. governing equations bulk fracture material points formulated the current/de...

Understanding how grain and powder lubrication affect rock friction and fracture dilation, and how microscopic fractures develop according to fault activation may directly improve our capabilities in exploration and stimulation of oil and gas reservoirs. Using a novel rotary shear testing apparatus specifically designed and assembled to conduct experiments inside an X-ray micro computed tomogra...
