Fracturing process with friction reduction coating

Abstract

A method to provide a fractured subterranean formation is provided, the method including the steps of: providing a wellbore from a surface location to the subterranean formation; applying a friction reduction treatment to at least a portion of an inside surface of a casing; cementing the casing with the applied friction reduction treatment into at least a portion of the wellbore; and pumping into the wellbore a fluid at a pressure that exceeds a fracture pressure of the subterranean formation thereby forming at least one fracture within the subterranean formation wherein the fluid is in contact with at least a portion of the inside surface of the casing with the applied friction reduction treatment.

It is respectfully requested that the claims be amended as follows: 
     
         1 . A method to provide a fractured subterranean formation comprising:
 providing a wellbore from a surface location to the subterranean formation;   applying a coating selected from the group consisting of epoxy coatings and nylon coatings to at least a portion of an inside surface of a casing;   cementing the casing into at least a portion of the wellbore with the applied coating; and   pumping into the wellbore a fluid at a pressure that exceeds a fracture pressure of the subterranean formation thereby forming at least one fracture within the subterranean formation wherein the fluid is in contact with at least a portion of the inside surface of the casing with the coating.   
     
     
         2 . (canceled) 
     
     
         3 . (canceled) 
     
     
         4 . (canceled) 
     
     
         5 . The method of  claim 1  further comprising the step of producing hydrocarbons from the subterranean formation 
     
     
         6 . (canceled) 
     
     
         7 . The method of  claim 1  wherein the fluid comprises a proppant. 
     
     
         8 . The method of  claim 1  wherein the fluid comprises a component that reacts with at least one component of the subterranean formation to cause that component to be at least temporarily dissolved and transported from the surface of the fracture. 
     
     
         9 . The method of  claim 7  wherein the proppant is sand. 
     
     
         10 . The method of  claim 7  wherein the proppant comprises ceramic particles. 
     
     
         11 . The method of  claim 1  wherein at least a portion of the wellbore within the subterranean formation is essentially horizontal. 
     
     
         12 . The method of  claim 11  wherein fractures are produced at a plurality of locations within the essentially horizontal section of the wellbore. 
     
     
         13 . The method of  claim 1  wherein the subterranean formation has a permeability of less than 1 millidarcy. 
     
     
         14 . The method of  claim 5  wherein the hydrocarbon produced comprises natural gas. 
     
     
         15 . The method of  claim 14  wherein the hydrocarbon produced consists essentially of natural gas. 
     
     
         16 . The method of  claim 5  wherein the hydrocarbon produced comprises light tight oil. 
     
     
         17 . The method of  claim 5  wherein the subterranean formation is a hydrocarbon source rock formation.
