Methods of consolidating unconsolidated particulates in subterranean formations

Abstract

Methods for stabilizing portions of a subterranean formation that comprise unconsolidated particulates. In one embodiment, the methods of the present invention comprise: providing a consolidating agent; introducing the consolidating agent into an unconsolidated portion of a subterranean formation through a dynamic diversion tool; and allowing the consolidating agent to at least partially consolidate the unconsolidated portion of the subterranean formation.

1 . A method comprising: 
 providing a consolidating agent;    introducing the consolidating agent into an unconsolidated portion of a subterranean formation through a dynamic diversion tool; and    allowing the consolidating agent to at least partially consolidate the unconsolidated portion of the subterranean formation.    
   
   
       2 . The method of  claim 1  wherein the unconsolidated portion of the subterranean formation comprises one or more fractures within the subterranean formation.  
   
   
       3 . The method of  claim 1  wherein the consolidating agent is selected from the group consisting of resins, tackifying agents, gelable liquid compositions, derivatives thereof and combinations thereof.  
   
   
       4 . The method of  claim 1  wherein the dynamic diversion tool is selected from the group consisting of ported-sub assemblies, hydroblast tools, hydrajetting tools, pulsonic tools and combinations thereof.  
   
   
       5 . The method of  claim 1  wherein providing a consolidating agent comprises providing a treatment fluid that comprises the consolidating agent; and 
 introducing the consolidating agent into an unconsolidated portion of the subterranean formation comprises introducing the treatment fluid that comprises the consolidating agent into the unconsolidated portion of a subterranean formation.    
   
   
       6 . The method of  claim 1  wherein the unconsolidated portion of the subterranean formation comprises one or more fractures within the subterranean formation wherein a plurality of particulates reside within the open space of the one or more fractures.  
   
   
       7 . The method of  claim 1  wherein the unconsolidated portion of the subterranean formation comprises a plurality of unconsolidated proppant particulates.  
   
   
       8 . The method of  claim 1  further comprising introducing a preflush fluid into a portion of the subterranean formation.  
   
   
       9 . The method of  claim 1  further comprising introducing an afterflush fluid into a portion of the subterranean formation.  
   
   
       10 . The method of  claim 1  wherein the subterranean formation comprises one or more casing strings, screens, gravel-packs, or a combination thereof.  
   
   
       11 . The method of  claim 1  further comprising placing a static diverting agent within a portion of the subterranean formation.  
   
   
       12 . The method of  claim 1  further comprising propelling a fluid through the dynamic diversion tool at a pressure sufficient to erode and/or fracture a portion of the subterranean formation.  
   
   
       13 . A method comprising: 
 providing a consolidating agent;    introducing the consolidating agent into an unconsolidated portion of a subterranean formation through a dynamic diversion tool, wherein a plurality of unconsolidated proppant particulates reside within the subterranean formation; and    allowing the consolidating agent to at least partially consolidate the unconsolidated proppant particulates within the unconsolidated portion of the subterranean formation.    
   
   
       14 . The method of  claim 13  wherein the consolidating agent is selected from the group consisting of resins, tackifying agents, gelable liquid compositions, derivatives thereof and combinations thereof.  
   
   
       15 . The method of  claim 13  further comprising placing a static diverting agent within a portion of the subterranean formation.  
   
   
       16 . The method of  claim 13  wherein the unconsolidated portion of the subterranean formation comprises one or more fractures within the subterranean formation wherein the plurality of unconsolidated proppant particulates reside within the open space of the one or more fractures.  
   
   
       17 . A method comprising: 
 providing a consolidating agent;    introducing the consolidating agent into an unconsolidated portion of a subterranean formation through a dynamic diversion tool, wherein a plurality of unconsolidated formation particulates reside within the subterranean formation; and    allowing the consolidating agent to at least partially consolidate the unconsolidated formation particulates within the subterranean formation.    
   
   
       18 . The method of  claim 17  wherein the consolidating agent is selected from the group consisting of resins, tackifying agents, gelable liquid compositions, derivatives thereof and combinations thereof.  
   
   
       19 . The method of  claim 17  further comprising placing a static diverting agent within a portion of the subterranean formation.  
   
   
       20 . The method of  claim 17  wherein the unconsolidated portion of the subterranean formation comprises one or more fractures within the subterranean formation wherein the plurality of unconsolidated formation particulates reside within the open space of the one or more fractures.
