... the effect of the fracture wall and in the interaction of multiple particles. Furthermore, some numerical results for different concentrations of injected solids are shown to exhibit the effect of this parameter on the final geometry of the fracture. The slurry viscosity and vertical pressure gradient can...

... = initial permeability; k = current permeability; 0 = initial porosity; = current porosity; v = volumetric strain. Vaziri [4] proposed an expression of permeability of oil sands as a function of change in void ratio, saturation and viscosity, assuming a single-phase fluid filled the pore of oil sands: 3...

... sliding) at different levels of confining pressure (500, 2000, 5000 psi). Viscosity and lubricating effects of the fluids and chemical interactions of the pore fluids with the quartz grains of the gouge are the processes envisioned as affecting the mechanical properties of the experimental faults...

... Republic of China ABSTRACT: This study presents the empirical relations between creep parameters, including initial creep stress, failure creep stress, elastic modulus, viscosity, cohesion and friction angle, and water content, derived from the experimental data of a series of creep tests on several rocks...

Paper Number: ARMA-2000-1185
... ABSTRACT ABSTRACT: Laboratory hydraulic fracturing tests were performed in cylindrical specimens of highly porous Berea sandstones (17% and 25%). We were able to raise the borehole pressure so as to induce hydraulic fractures by increasing the viscosity of the borehole injection-fluid as well...

Paper Number: ARMA-96-1251
... Abstract: We present theory and experiments on the relation between pressurisation rate and fluid viscosity and the fracture initiation pressure and fracture geometry. We observed a strong increase in initiation pressure with pressurisation rate. The theory explains qualitatively the observed...
