Abstract
The present invention provides methods for fracturing and for reducing the production of both water and particulates from subterranean formations. The methods are particularly useful in conjunction with subterranean formations surrounding wellbores and fractures. The methods comprise the steps of applying to a subterranean formation gelled fluid that contains a gelling agent and a water resistant polymer, applying aqueous surfactant fluid, applying a low-viscosity consolidating fluid, and applying an after-flush fluid, and (in some embodiments) a crosslinked gel fluid.
