Apr 07, 2014 · INTRODUCTION. Hydraulic fracturing is a commonly used technique to stimulate hydrocarbon production by creating a network of highly conductive fractures in the area surrounding a wellbore. 1 The network of fractures created not only improves hydraulic conductivity of the reservoir rock but also increases the surface area contributing to hydrocarbon production.

Sep 01, 2016 · In hydraulic fracturing, initially, a high fracturing viscosity is desired to enable the effective transport and deposition of large volumes of proppant (sand) into the fissures. The apparent viscosity of commercially used fracturing fluids is generally 50–2000 times larger than that of water (Gaillard et al., 2013).

because increased viscosity is known to increase the dynamic resistance when creating an interface and the high solids concentrations in the slurries probably increased the viscosity sufficiently to cause this effect. Overall, the dynamic surface tension of K Basin slurries under spray conditions is expected to be equal to the value of pure water.
