Methods of Cleaning Sand Control Screens and Gravel Packs

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.

1 . An apparatus for use in a subterranean formation chosen from the group consisting of a sand control screen, a liner, a gravel pack, or combination thereof and comprising a consolidating agent. 
   
   
       2 . The apparatus of  claim 1  wherein the sand control screen is a wire-wrapped screen, a pre-packed screen, or an expandable screen. 
   
   
       3 . The apparatus of  claim 1  wherein the consolidating agent comprises at least one member selected from the group consisting of a non-aqueous tackifying agent, an aqueous tackifying agent, a resin, a gelable composition, and combinations thereof. 
   
   
       4 . The apparatus of  claim 1  wherein the apparatus is a sand control screen that comprises an adjacent fluidic oscillator.
