An investigation is performed to study the effect of suction/injection on unsteady hydromagnetic natural convection flow of viscous reactive fluid between two vertical porous plates in the presence of thermal diffusion. The partial differential equations governing the flow have been solved numerically using semi-implicit finite-difference scheme. For steady case, analytical solutions have been ...

The transport of chemically reactive fluids through fractured clay-rich rocks is fundamental to many subsurface engineering technologies. Here, we present results direct-shear laboratory experiments with simultaneous imaging by X-ray Computed Tomography in Opalinus claystone subsequent fluid injection unravel the interplay between mechanical fracture deformation, sorption, and flow. Under const...

Enhanced oil recovery using nitrogen injection is a commonly applied method for pressure maintenance in conventional reservoirs. Numerical simulations can be practiced for the prediction of a reservoir performance in the course of injection process; however, a detailed simulation might take up enormous computer processing time. In such cases, a simple statistical model may be a good approach to...

Microearthquake activity at the Southeast Geysers, California, geothermal field is monitored with a highresolution digital seismic network. Hypocenters are spatially clustered in both injection and production areas, but also occur in more diffuse patterns, mostly at depths from 1 to 2.8 km. Hypocenters near the injection well DV-11 exhibit a striking correlation with movement of injectate and i...

In this paper, the interfacial motion between two immiscible viscous fluids in confined geometry of a Hele-Shaw cell is studied. We consider influence thin wetting film trailing behind displaced fluid, which dynamically affects pressure drop at fluid-fluid interface by introducing nonlinear dependence on velocity. framework, cases interest are analyzed: The injection-driven flow (expanding evol...

A three-dimensional poroelastic model is developed to investigate the poroelastic effect of fluid injection into a geothermal reservoir. In the model, the fluid flow in the fracture is assumed to be lubrication flow and modeled by the finite element method. The threedimensional pore fluid diffusion in the reservoir and the induced stresses are modeled by the boundary integral equation method. T...

Acute cord cavities have been produced by injection of saline or cerebrospinal fluid into the spinal cords of five beagle dogs. The lesions resemble syringomyelia as seen in the human. The lesions are described and the significance of the findings in supporting a hydrodynamic concept for communicating syringomyelia in the human are discussed.

We study mixing of two fluids of different viscosity in a microfluidic channel or porous medium. We show that the synergetic action of alternating injection and viscous fingering leads to a dramatic increase in mixing efficiency at high Péclet numbers. Based on observations from high-resolution simulations, we develop a theoretical model of mixing efficiency that combines a hyperbolic mixing mo...
