Imbibition of hydraulic fracturing fluids into partially saturated shale [PDF]
Water Resources Research, 2015 AbstractRecent studies suggest that imbibition of hydraulic fracturing fluids into partially saturated shale is an important mechanism that restricts their migration, thus reducing the risk of groundwater contamination. We present computations of imbibition based on an exact semianalytical solution for spontaneous imbibition. These computations lead to

Yield stress fluids solidifying in capillary imbibition
Journal of Fluid MechanicsWhen subjected to external stress exceeding their yield stress ( $\sigma _{Y}$ ), yield stress fluids (YSFs) undergo transition from solid to liquid. While the flow dynamics of capillary flows – including wetting, coating, spreading, and wicking – can be predicted accurately for fluids without yield stress, only a few ...

Fluid drainage from the edge of a porous reservoir [PDF]
We report theoretical and experimental studies to describe buoyancy-driven fluid drainage from a porous medium for configurations where the fluid drains from an edge. We first study homogeneous porous systems.

Arthritis Care &Research, Accepted Article.Objective Routine liver enzyme monitoring is advocated while on allopurinol but supporting guidance is lacking. We assessed the incidence and factors associated with elevated liver enzymes in gout patients commenced on allopurinol. Methods 150 patients with gout and normal baseline serum aminotransferases initiated on allopurinol were followed ...

Journal of Petroleum Exploration and Production TechnologyFluid soaking after hydraulic fracturing of shale reservoirs is generally believed essential for improving oil/gas productivity of wells in shale reservoirs. Factors affecting the effectiveness of post-frac fluid soaking has not been fully explored.

Energies, 2020 Post-fracturing well shut-in is traditionally due to the elastic closure of hydraulic fractures and proppant compaction. However, for shale gas wells, the extension of shut-in time may improve the post-fracturing gas production due to formation energy ...

Arthritis Care &Research, Accepted Article.Objective We describe the frequency, risk factors, severity, and management of actionable and serious adverse events (AAE and SAE) in children with newly diagnosed Juvenile Idiopathic Arthritis (JIA) in Canada. Methods We enrolled patients within 3 months of JIA diagnosis in the Canadian Alliance of Pediatric Rheumatology Investigators (CAPRI) Registry,
