Evaluation of sintered bauxite proppant for binary enhanced geothermal systems
Geomechanics and Geophysics for Geo-Energy and Geo-ResourcesSolid granular proppant particles are widely used in oil and gas development to sustain permeability through fractures after hydraulic stimulation. Similar proppants are of interest for geothermal applications where the goal of sustaining permeability is

Numerical Simulation Of Horizontal Migration Of Proppant
, 2008 The horizontal migration of proppant was numerically investigated with a two-fluid model, in which the interaction between fracturing fluid and proppant, along with that among proppants was taken into account through interphase forces.
