Stratigraphic traps associated with barrier island model Case 3. Stratigraphic traps associated with shelf sandstone model Reservoir Quality Play Concept Thomson sandstone (local usage) Gen...

Surface coal mining in Appalachia disturbs hundreds of hectares of land every year with the removal of valuable and ecologically diverse eastern deciduous forests. After the passage of the Surface Mining Control and Reclamation Act in 1977, coal mine operators began planting a variety of grasses and legumes as a fast and economical way to reestablish a permanent vegetative cover to meet erosion...

We show that direct estimates of the permeability hydrate-bearing geological formations are possible from remote measurements shear wave velocity (Vs) and attenuation (Qs?1). measured Vs, Qs?1 electrical resistivity at time intervals during methane hydrate formation in Berea sandstone using a laboratory ultrasonic pulse-echo system. observed Vs both increase with saturation Sh, two peaks satura...

Streaming potential is a promising method for variety of hydrogeophysical applications, including the characterisation critical zone, contaminant transport or saline intrusion. A simple bundle capillary tubes model that accounts realistic pore and throat size distribution porous rocks presented in this paper to simulate electrokinetic coupling coefficient compared with previously published mode...

We present an interface tracking algorithm that incorporates essential pore-scale invasion mechanisms for simulating multiphase flow in porous media capillary dominated regime. The allows the capture of actual shape medium with complex geometrical features, including both convex and concave particles or irregular channels. It also sharp edge pinning effect such menisci at corners can be natural...

Torsional vibrations of composite poroelastic dissipative spherical shell are investigated in the framework of Biot’s extension theory.Here composite poroelastic spherical shell consists of two spherical shells, one is placed on other, and both are made of different poroelastic materials. Consideration of the stress-free boundaries of outer surface and the perfect bonding between two shells lea...

Surface mining in West Virginia removes the eastern deciduous forest and reclaiming the mined land to a productive forest must consider soil depth, soil physical and chemical properties, soil compaction, ground cover competition, and tree species selection. Our objective was to evaluate tree survival and growth in weathered brown sandstone and in unweathered gray sandstone. Brown and gray sands...

Abstract Accurate stress–strain measurements in triaxial tests are critical to compute reliable mechanical parameters. We focus on compliance at the interfaces between specimen and endcaps, test specimens under various conditions using different instrumentation protocols. The tested materials include aluminum, Eagle Ford shale, Berea sandstone, Jubaila carbonate. Results obtained following comm...
