Method and system for retrieving a whipstock with a drill bit in a wellbore

Abstract

A system includes a retrieving tool component with a first engagement element disposed at a first radial distance from a retrieving tool centerline. The system includes an uphole component comprising a second engagement element. The system includes a downhole component coupled to the uphole component and releasably connected to a wellbore. The retrieving tool component is configured to retrieve the uphole component and the downhole component from the wellbore using a connection component to release an axial lock thereby allowing an axial movement of the downhole component out of the wellbore.

What is claimed is: 
     
         1 . A system comprising:
 a retrieving tool component comprising a first engagement element disposed at a first radial distance from a retrieving tool centerline;   an uphole component comprising a second engagement element; and   a downhole component coupled to the uphole component and releasably connected to a wellbore;   wherein the retrieving tool component is configured to retrieve the uphole component and the downhole component from the wellbore using a connection component to release an axial lock thereby allowing an axial movement of the downhole component out the wellbore.   
     
     
         2 . The system of  claim 1 ,
 wherein the axial lock comprises a slip selectively extendible between an unlocked position and a locked position;   wherein the slip is initially configured in the locked position to prevent the axial movement of the downhole component within the wellbore,   wherein the slip is moved into the unlocked position upon engagement by the retrieving tool component.   
     
     
         3 . The system of  claim 2 , wherein the slip comprises a slip release. 
     
     
         4 . The system of  claim 1 , wherein the first engagement element comprises an engagement hook. 
     
     
         5 . The system of  claim 4 , wherein the engagement hook has a tapered length and a reduced distance from the retrieving tool centerline. 
     
     
         6 . The system of  claim 1 , wherein the retrieving tool component further comprises a drilling bit. 
     
     
         7 . The system of  claim 1 , wherein the second engagement element comprises a catch. 
     
     
         8 . The system of  claim 7 ,
 wherein the catch comprises a catch first end and a catch opening, the catch opening configured to receive the first engagement element;   wherein the catch is hingedly connected to the uphole component with a catch hinge at a catch second end;   wherein the catch hinge comprises a catch hinge axle.   
     
     
         9 . The system of  claim 8 ,
 wherein the catch is selectively extendable between a recessed position and an extended position;   wherein the catch is disposed in a pocket disposed in the uphole component; and   wherein the catch further comprises a shear element coupling the catch with the pocket such that the shear element prevents an axial catch movement of the catch relative to the pocket;   wherein the shear element comprises the catch hinge axle.   
     
     
         10 . The system of  claim 1  further comprising:
 an extending driver configured to extend the second engagement element from a recessed position to an extended position. 
 
     
     
         11 . The system of  claim 10 , wherein the extending driver is powered by a power supply. 
     
     
         12 . The system of  claim 11 , wherein the second engagement element is electro-mechanically actuated. 
     
     
         13 . The system of  claim 12  further comprising:
 a retainer configured to cooperate with the uphole component to retain the second engagement element in the recessed position using a retainer driver operable by an electronics module. 
 
     
     
         14 . The system of  claim 13 , wherein the electronics module comprises a sensor configured to sense an activation device. 
     
     
         15 . A method for retrieving an uphole component coupled to a downhole component deployed in a wellbore, the method comprising:
 deploying a retrieving tool component into the wellbore, the retrieving tool component comprising a first engagement element;   drilling a lateral wellbore section with the retrieving tool component;   extending a second engagement element disposed on the uphole component;   engaging the second engagement element with the first engagement element;   applying an uphole tension on the second engagement element to unlock the downhole component from the wellbore; and   removing the retrieving tool component connected to the uphole component and the downhole component from the wellbore.   
     
     
         16 . The method of  claim 15 , wherein deploying a retrieving tool component comprises deploying a drill bit. 
     
     
         17 . The method of  claim 15 , wherein extending the second engagement element comprises electro-mechanically actuating the second engagement element. 
     
     
         18 . The method of  claim 15 , wherein extending the second engagement element comprises signaling an electronics module to activate a retainer driver to shift a retainer to unlatch the second engagement element. 
     
     
         19 . The method of  claim 15 , wherein unlocking the downhole component from the wellbore further comprises transferring the uphole tension through a connection component to release an axial lock to axially move the downhole component from the wellbore. 
     
     
         20 . The method of  claim 15 , wherein drilling the lateral wellbore section, removing the retrieving tool component, removing the uphole component, releasing the downhole component, and removing the downhole component are completed in a single trip into and out of the wellbore.
