We present spatial distributions for pore path length and coordination number, pore throat size and nodal pore volume obtained for a 1:53 mm3 volume of 12.1% porosity Fontainebleau sandstone. The sandstone was imaged using Synchrotron X-Ray computed microtomography at 6 micron resolution. The spatial distributions were computed based upon three dimensional medial axis analysis of the void space...

A two-dimensional micro-scale model for crystal dissolution and precipitation in a porous medium is presented. The local geometry of the pore is represented as a thin strip. The model allows for changes in the pore volume. A formal limiting argument leads to a system of 1D effective upscaled equations. The effective equations allow for travelling wave solutions. Existence and uniqueness of thes...

A light scattering turbidity method has been employed to measure the dimensionless colloidal osmotic compressibility of carefully characterized model athermal colloid (silica)-polymer (polystyrene) suspensions. Mixture thermodynamics is controlled by purely repulsive, hard sphere interactions between the particles while the polymer is in a good solvent. Polymer size is varied by nearly 2 orders...

the goal of this laboratory study is to investigate the effect of pore shapes on seismic wave velocities in carbonate rocks under reservoir conditions. in this research, 41 core plugs of carbonate rocks from oil fields of the southwest of iran were prepared. the compressional and shear wave velocities were measured in both dry and brine saturated samples under several pressures especially reser...

The thermodynamic properties of water are of fundamental importance to perform geochemical, reservoir and production engineering calculations in the geothermal industry. Using the IAPWS-95 formulation an ActiveX component, SteamTablesIIE is developed to calculate thermodynamic properties of pure water as a function of two independent intensive variables: (1) temperature (T) or pressure (P) and ...

The paper is devoted to the homogenization of porous piezoelectric materials saturated by electrically inert fluid. The solid part of a representative volume element consists of the piezoelectric skeleton with embedded conductors. The pore fluid in the periodic structure can constitute a single connected domain, or an array of inclusions. Also the conducting parts are represented by several mut...

Injection-induced rock mechanical failure risks are critical in CO2 sequestration, and thus there is a need to evaluate these occurrences ensure safe reliable subsurface storage. A stress–strain-based numerical simulation can reveal the potential of any sites. This study investigated hydromechanical effect on geomechanical due injection-induced stress pore pressure changes prospective storage s...
