... high viscosity, typically result in height growth rather than increased fracture length. With VES fluids proppant transport is based on the elasticity and structure rather than the viscosity of fluid. Therefore VES fluids efficiently transport proppants at lower viscosities. At the same time, VES...

... analysis shows that proppant convection/encapsulation is a density/viscosity related mechanism. It is indicated that encapsulation (downward motion of proppant) dominates particle settling in a low viscous medium such as water or linear gel. This phenomena, however, diminishes as viscosity of the lower...
