Method and composition to divert fluids at high temperatures

Abstract

Methods of treating a subterranean formation as a portion of steam-assisted gravity drainage operation including providing a fluid containing a diverting agent, injecting the fluid into a first wellbore, allowing the diverting agent to divert fluid placement, performing steam-assisted gravity drainage, and producing formation fluids from a second wellbore.

1 . A method of treating a subterranean formation as a portion of steam-assisted gravity drainage operation, the method comprising:
 a. providing a fluid comprising a diverting agent;   b. injecting the fluid into a first wellbore;   c. allowing the diverting agent to divert fluid placement;   d. performing steam-assisted gravity drainage; and,   e. producing formation fluids from a second wellbore.   
     
     
         2 . The method of  claim 1  wherein the diverting agent is functional at high temperature. 
     
     
         3 . The method of  claim 1  wherein the fluid further comprises a particulate. 
     
     
         4 . The method of  claim 3  wherein the particulate further comprises glass bubbles to reduce the density. 
     
     
         5 . The method of  claim 3  wherein the particulate has a high surface areas to facilitate entrainment in steam. 
     
     
         6 . The method of  claim 1  wherein the diverting agent is a fibrous material. 
     
     
         7 . The method of  claim 1  wherein the diverting agent is a nonfibrous material. 
     
     
         8 . The method of  claim 1  wherein the diverting agent is a fibrous bridging agent. 
     
     
         9 . The method of  claim 1  wherein the diverting agent is a nonfibrous bridging agent. 
     
     
         10 . The method of  claim 1  further comprising utilization of an adhesive binder. 
     
     
         11 . The method of  claim 10  wherein the adhesive binder is a permanent adhesive. 
     
     
         12 . The method of  claim 10  wherein the adhesive binder is a temporary adhesive. 
     
     
         13 . The method of  claim 1  wherein the diverting agent is placed by an active placement method. 
     
     
         14 . The method of  claim 1  wherein the diverting agent is placed by a passive placement method. 
     
     
         15 . A method of treating a subterranean formation as a portion of steam-assisted operation, the method comprising:
 a. providing a fluid comprising a diverting agent;   b. injecting the fluid into a first wellbore;   c. allowing the diverting agent to divert fluid placement; and,   d. performing steam-assisted production of formation fluids from a second wellbore.   
     
     
         16 . The method of  claim 15  wherein the diverting agent is functional at high temperature. 
     
     
         17 . The method of  claim 15  wherein the fluid further comprises a particulate. 
     
     
         18 . The method of  claim 17  wherein the particulate further comprises glass bubbles to reduce the density. 
     
     
         19 . The method of  claim 17  wherein the particulate has a high surface areas to facilitate entrainment in steam. 
     
     
         20 . The method of  claim 15  wherein the diverting agent is a fibrous material or nonfibrous material. 
     
     
         21 . The method of  claim 15  further comprising utilization of an adhesive binder, wherein the adhesive binder is either a permanent adhesive or temporary adhesive. 
     
     
         22 . The method of  claim 15  wherein the diverting agent is placed by an active placement method or a passive placement method. 
     
     
         23 . A method of treating a subterranean formation comprising:
 a. providing a fluid comprising a diverting agent and adhesive;   b. injecting the fluid into a first wellbore;   c. allowing the diverting agent to divert fluid placement; and,   d. performing steam-assisted production of formation fluids from a second wellbore.
