Abstract
The present invention provides methods of 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 a pre-flush fluid, applying aqueous surfactant fluid, applying a low-viscosity consolidating fluid, and applying an after-flush fluid.
