Fluid communication method for hydraulic fracturing

Abstract

Aspects of the disclosed technology provide techniques for facilitating hydrocarbon extraction from a wellbore. In some aspects, the disclosed technology encompasses a novel casing string that includes at least one casing section, an aperture disposed on a surface of the casing section, and an insert affixed around a periphery of the aperture. The casing string can further include a plug disposed within the insert, wherein the plug is configured to be selectively removable to allow fluid communication between an interior volume of the casing string and an exterior of the casing string, e.g., adjacent to a geologic formation.

1 . A casing string configured for facilitating hydrocarbon extraction from a wellbore, the casing string comprising:
 at least one casing section;   an aperture disposed on a surface of the of the at least one casing section;   an insert affixed around a periphery of the aperture; and   a plug disposed within the insert, wherein the plug is configured to be selectively removable to allow fluid communication between an interior volume of the casing string and an exterior of the casing string adjacent to a geologic formation.   
     
     
         2 . The casing string of  claim 1 , wherein the insert is configured to prevent erosion of the internal edge of the aperture in order to maintain a diameter of the aperture. 
     
     
         3 . The casing string of  claim 1 , wherein the insert comprises a carbide composite. 
     
     
         4 . The casing string of  claim 1 , wherein the plug is configured to be removed from the insert by an explosive device. 
     
     
         5 . The casing string of  claim 1 , wherein the plug is configured to be removed from the insert by heat. 
     
     
         6 . The casing string of  claim 1 , wherein the plug is configured to dissolve upon contact with a chemical cutter. 
     
     
         7 . The casing string of  claim 6 , wherein the chemical solution comprises bromine tri-fluoride. 
     
     
         8 . The casing string of  claim 6 , wherein the chemical solution comprises an acid. 
     
     
         9 . The casing string of  claim 1 , wherein the plug comprises zinc. 
     
     
         10 . The casing string of  claim 1 , wherein the plug comprises aluminum. 
     
     
         11 . The casing string of  claim 1 , wherein the plug comprises ceramic, calcium carbonate, or dolomite. 
     
     
         12 . A method for constructing a casing string configured for facilitating hydrocarbon extraction from a wellbore, the casing string comprising:
 inserting an aperture in at least one casing section, wherein the aperture is disposed on a surface of the of the at least one casing section;   affixing an insert around a periphery of the aperture; and   placing a plug within the insert, wherein the plug is configured to be selectively removable to allow fluid communication between an interior volume of the casing string and an exterior of the casing string adjacent to a geologic formation.   
     
     
         13 . The method of  claim 12 , wherein the insert is configured to prevent erosion of the internal edge of the aperture in order to maintain a diameter of the aperture. 
     
     
         14 . The method of  claim 12 , wherein the insert comprises a carbide composite. 
     
     
         15 . The method of  claim 12 , wherein the plug is configured to be removed from the insert by an explosive device. 
     
     
         16 . The method of  claim 12 , wherein the plug is configured to be removed from the insert by heat. 
     
     
         17 . The method of  claim 12 , wherein the plug is configured to dissolve upon contact with a chemical cutter. 
     
     
         18 . The method string of  claim 17 , wherein the chemical solution comprises bromine tri-fluoride. 
     
     
         19 . The method string of  claim 17 , wherein the chemical solution comprises an acid. 
     
     
         20 . A wellbore casing section, comprising:
 at least one aperture disposed on a surface of the casing section;   an insert affixed around a periphery of the aperture; and   a plug disposed within the insert, wherein the plug is configured to be selectively removable to facilitate communication between an interior volume of the casing section and an exterior of the casing section.
