Abstract
Methods for remediating a subterranean environment. Methods comprising introducing a cleanup fluid through a well bore and into a portion of a subterranean formation penetrated by the well bore, applying a pressure pulse to the cleanup fluid, and introducing a consolidating agent through the well bore and into the portion of the subterranean formation. Methods of cleaning a sand control screen comprises introducing a cleanup fluid through a sand control screen and into a portion of a subterranean formation, the sand control screen located in a well bore that penetrates the subterranean formation; applying a pressure pulse to the cleanup fluid; and introducing a consolidating agent through the sand control screen and into the portion of the subterranean formation.

28. A method of cleaning a sand control screen and gravel pack comprising:
-
placing a fluidic oscillator in a well bore in a location adjacent to a sand control screen located in the well bore;
introducing a cleanup fluid through the fluidic oscillator, through the sand control screen, through a gravel pack, and into a portion of a subterranean formation penetrated by the well bore, wherein the gravel pack is located in an annulus between the sand control screen and the portion of the subterranean formation and wherein a pressure pulse is generated in the cleanup fluid by introducing the cleanup fluid through the fluidic oscillator; and
introducing a consolidating agent through the sand control screen, through the gravel pack, and into the portion of the subterranean formation.
