Abstract

The method for orienting hydraulic fractures in a subterranean formation comprises injecting a first fluid into a first horizontal wellbore penetrating the subterranean formation and open to the formation in at least one specified segment and pressurizing the first fluid in the first wellbore to create a stress field around each specified segment of the first wellbore. A second pressurized fracturing particle-laden fluid is simultaneously injected into a second horizontal wellbore open to the formation in at least one specified segment and vertically spaced apart from the first wellbore for inducing fractures propagating from the specified segments of the second wellbore towards the specified pressurized segments of the first wellbore.

Claims

exact text as granted — not AI-modified
What is claimed is: 
     
         1 . A method for orienting hydraulic fractures in a subterranean formation, the method comprising:
 injecting a first fluid into a first horizontal wellbore that penetrates the subterranean formation and is open to the formation in at least one specified segment,   pressurizing the first fluid in the first wellbore to create a stress field around each specified segment of the first wellbore,   simultaneously injecting a second pressurized fracturing particle-laden fluid into a second horizontal wellbore that is vertically spaced apart from the first wellbore and is open to the formation in at least one specified segment for inducing fractures propagating from the specified segments of the second wellbore towards the pressurized specified segments of the first wellbore.   
     
     
         2 . The method of  claim 1  wherein the first and the second wellbores are lateral wellbores of a multilateral well. 
     
     
         3 . The method of  claim 1  wherein the second pressurized fracturing particle-laden fluid is used as the first fluid injected into the first wellbore. 
     
     
         4 . The method of  claim 1  wherein the first fluid injected into the first wellbore is a natural gas. 
     
     
         5 . The method of  claim 1  wherein the first wellbore is open to the formation through open perforation clusters. 
     
     
         6 . The method of  claim 1  wherein the first wellbore is open to the formation though sliding sleeves. 
     
     
         7 . The method of  claim 1  wherein the second wellbore is open to the formation through open perforation clusters. 
     
     
         8 . The method of  claim 1  wherein the second wellbore is open to the formation through sliding sleeves.
