Methods of treatment of a subterranean formation with polymeric structures formed in situ

Abstract

Methods of treating a subterranean formation are disclosed that include placing a treatment fluid into a subterranean formation, the treatment fluid containing a one or more polymers capable of consolidating to form a polymeric structure at a downhole location. Also disclosed are treatment fluids including a polymeric structure for treating a subterranean formation.

1 . A fluid for treating a subterranean formation comprising:
 a solvent; and   a polymeric structure comprising one or more polymers; wherein the polymeric structure is formed by consolidating the one or more polymers during a shear event.   
     
     
         2 . The fluid for treating the subterranean formation of  claim 1 , wherein the fluid is selected from the group consisting of a fluid loss control pill, a water control treatment fluid, a scale inhibition treatment fluid, a fracturing fluid, a gravel packing fluid, a drilling fluid, and a drill-in fluid. 
     
     
         3 . The fluid for treating the subterranean formation of  claim 1 , wherein the polymeric structure comprises one or more pH sensitive polymers. 
     
     
         4 . The fluid for treating the subterranean formation of  claim 1 , wherein the polymeric structure comprises a seed particle or seed fiber. 
     
     
         5 . The fluid for treating the subterranean formation of  claim 1 , wherein the polymeric structure comprises one or more proppant particles. 
     
     
         6 . The fluid for treating the subterranean formation of  claim 1 , wherein the polymeric structure has an aspect ratio of at least 2:1. 
     
     
         7 . The fluid for treating the subterranean formation of  claim 1 , wherein the polymeric structure is a solid. 
     
     
         8 . The fluid for treating the subterranean formation of  claim 1 , wherein the polymeric structure is a gel. 
     
     
         9 . The fluid for treating the subterranean formation of  claim 1 , wherein the polymeric structure comprises one or more crosslinked polymers.
