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.
Claims33
A method of reducing the production of particulates and water from a subterranean formation comprising the steps of:
- applying a preflush solution comprising an aqueous liquid and a water-resistant polymer to the subterranean formation;
- applying an aqueous liquid comprising a surfactant into the subterranean formation;
- applying a low-viscosity consolidating fluid to the subterranean formation;
- and,
- applying an afterflush fluid to the subterranean formation.
