Wireless perforating gun

Abstract

An apparatus and method for wirelessly perforating a wellbore casing. The apparatus includes a body, at least one explosive charge, a trigger, a depth correlation device, a detonator cord, and a detonator. The depth correlation device is programmed to send a signal to the trigger to ignite/fire the detonator, which ignites the detonator cord and explosive charges. The method utilizes the apparatus of the present invention to perforate a wellbore casing.

What is claimed is: 
     
         1 . A fragmenting perforating gun for use in a wellbore casing, comprising:
 a body;   at least one explosive charge;   a trigger;   a depth correlation device;   a detonator cord; and   a detonator,
 wherein the explosive charge, the trigger, the depth correlation device, detonator cord, and detonator are contained in the body, 
 wherein the depth correlation device is programed to activate the trigger at a certain pre-set variable, and 
 wherein the trigger activates the detonator, and in turn, the detonator cord and the explosive charge. 
   
     
     
         2 . The fragmenting perforating gun of  claim 1 , wherein the depth correlation device comprises a collar locator.

         9 . The fragmenting perforating gun of  claim 1 , wherein the body, the explosive charge, the trigger, the depth correlation device, the detonator cord, and the detonator are comprised of materials that are intended to not obstruct flow through the perforations after detonation. 
     
     
         10 . The fragmenting perforating gun of  claim 1 , wherein the explosive charge comprises a series of charges. 
     
     
         11 . A method for using the device of  claim 1  for use in a wellbore casing, comprising the steps of:
 programming the depth correlation device to activate the trigger at a certain pre-set variable; and 
 inserting the body into the wellbore casing,
 wherein the trigger activates the detonator, the detonator cord, and the explosive charge at the pre-set variable. 
 
 
     
     
         12 . A method for perforating a wellbore casing, the method being implemented by a fragmenting perforating gun body that contains an explosive charge, a trigger, a depth correlation device, a detonator cord, and a detonator, the method comprising the steps of:
 programming the depth correlation device to activate the trigger at a certain pre-set variable; and   inserting the fragmenting perforating gun body into the wellbore casing,
 wherein the trigger activates the detonator, the detonator cord, and the explosive charge at the pre-set variable. 
   
     
     
         13 . A fragmenting perforating gun body for use in a wellbore casing, comprising:
 an explosive charge;   a trigger;   a depth correlation device;   a detonator cord; and   a detonator,
