Paper Number: SPE-174187-MS
.... Walls 4 in 1981 conducted core testing on samples from Spirit river tight gas sand of Western Alberta and Cotton Valley Formation of East Texas for their effect of pressure, partial saturation and salinity on permeability. It was concluded that samples showed strong relation of permeability with...

Rod-shaped proppant is a single proppant flowback prevention product, which prevents flowback and increases conductivity at the same time. All other known methods, such resin-coated proppants (RCP), surface...

... stress in the subsurface, proppantsareused. The hydraulic conductivity (C f ) of such a fracture is defined as the permeability of the proppant pack (k pr ) times the fracture width (w f ). However, this value cannot be considered a constant. The increasing effective pressure leads to an increased stress...

.... They showed that once the proppant settles and the fracture closes, an arch forms at the top of the proppant bed, resulting in a very high-conductivity channel along the primary fracture. This presence of a high-conductivity arch can significantly impact fracture treatment design and reduce the...
