HDR samples are collected from the Department...

... model first uses the three-dimensional Displacement Discontinuity Method (DDM) to calculate displacement fields induced by hydraulic fractures. The model then takes into account the occurrence of slippage and calculate the fiber displacement distribution with slippage effect. Additionally, the model can...

... displacement of pore water from wet reservoirs during hydrocarbon emplacement. These forces are measured with capillary pressure drainage curves. Secondly, the capillary film water and oil phases are immiscible but also bonded to some degree by polar components within the oil that can bridge the interface...

... Abstract Water imbibition and associated oil displacement is an important process in shale oil reservoirs after hydraulic fracturing and in water-based enhanced oil recovery. Current techniques for water imbibition measurement are mostly "black-box" type of methods. More explicit understanding...

... of equations is used to generate simulated microseismic events for a fracturing treatment. The limited far-field displacement (LFFD) method, is used to generate expected microseismic events. These are then compared with measurements and used to infer the geometry of the created fracture network...

Consider that a constant line heat source with unit heat strength is located along each element at initial time, the temperature, displacements, and stresses at any arbitrary point can be calculated based on the integral fundamental solutions. We construct different numerical experiments...
