Experimental, Theoretical, and Numerical Investigations of Geomechanics/Flow Coupling in Energy Georeservoirs
… exerted on a shale formation has a significant effect on the rock's apparent permeability. Gas flow in low-permeability shales is significantly different from liquid flow due to the Klinkenberg effect caused by gas molecule slip at the nanopore wall surfaces. This has the effect of increasing …

Fracture optimization based on gradient descent methodology
… MSFLOW, with gas adsorption/desorption and Klinkenberg effect coupled, is adopted to obtain the production rate and NPV at each searching step. Armijo rule is used to determine the searching step size. With the developed workflow, we have investigated the optimal geometry of the fractures …

Flow mechanisms and numerical simulation of gas production from shale reservoirs
… including viscous flow, Knudsen diffusion, Klinkenberg effect, pore radius change, gas desorption, and gas viscosity change. Results show that adsorption and gas viscosity change will have a great impact on gas production. At last, the numerical simulation model for SGRs with multi-stage …

Using data analytics and laboratory experiments to advance the understanding of reservoir rock properties
… outcome indicated that certain variables were effectively correlated to the permeability. The 2D microfluidic model demonstrated the development of viscous fingering when the injection water flow rate was higher than a certain level, which resulted in reduced overall sweep efficiency. These …
