Selective running tool with separation feature

Abstract

A running tool that delivers an object selectively to one of a plurality of landing nipples and then releases from the object is disclosed. The tool is actuated by raising it after it has passed the desired landing nipple to release a locating dog. The locating dog places locking dogs on the object even with a groove on the landing nipple. Movement of the tool downhole secures the locking relationship and releases the running tool from the object. A sheer pin allows testing at the surface that the object is locked in place, prior to removal of the running tool. The object comprises a fishing neck to allow it to be subsequently retrieved.

1 . A tool assembly for delivering a downhole tool into a wellbore, comprising: 
 a body;    an indexing mechanism on said body selectively actuated to support said body in one of a plurality of wellbore locations;    an actuating assembly on said body selectively movable when said indexing mechanism supports said body in the wellbore for actuating an anchor on the downhole tool to support the downhole tool in the wellbore;    
     
     
         2 . The assembly of  claim 1 , further comprising: 
 a release device on said body for disconnecting said body from the downhole tool when the downhole tool is supported by its anchor;    a plurality of downhole downhole landing nipples mounted in the wellbore and serving as said plurality of locations for support of said body, said landing nipples comprising at least one locating groove and at least one locking groove.    
     
     
         3 . The assembly of  claim 2 , wherein: 
 said indexing mechanism comprises at least one indexing dog held in a retracted position to said body; and    a release assembly capable of passing through said landing nipples in a first direction while maintaining said indexing dog retained to said body, said release assembly allowing said indexing dog to extend when said body is moved into one of said landing nipples in a second direction opposite said first direction.    
     
     
         4 . The assembly of  claim 3 , further comprising: 
 a downhole tool releasably connected to said body and further comprising an anchoring dog, said anchoring dog aligned with said locking groove when said body is supported by said indexing dog in said locating groove.    
     
     
         5 . The assembly of  claim 4 , further comprising: 
 an inner and outer sleeve on said downhole tool, said actuating assembly selectively retained to said inner and outer sleeves to cause relative movement between them, said relative movement forcing said anchoring dog into a locked relation with said locking groove.    
     
     
         6 . The assembly of  claim 5 , further comprising: 
 said relative movement releases connection of said inner and outer sleeves to said body.    
     
     
         7 . The assembly of  claim 6 , further comprising: 
 at least one shear pin;    said shear pin maintaining contact with at least one of said inner and outer sleeves after said relative movement releases connection of said inner and outer sleeves to said body.    
     
     
         8 . The assembly of  claim 5 , further comprising: 
 said body further comprises a first dog to engage said outer sleeve and a second dog to engage said inner sleeve, whereupon movement of at least one of said first and second dogs with respect to the other said dogs release from their respective sleeves    
     
     
         9 . The assembly of  claim 8 , further comprising: 
 said sleeves lock to each other subsequent to relative movement between them that results in locking said anchoring dog in said locking groove.    
     
     
         10 . The assembly of  claim 8 , wherein: 
 said release of said first and second dogs occurs when grooves on a part of said body come into alignment with said first and second dogs.    
     
     
         11 . A method of placing a downhole tool in a well, comprising: 
 providing a plurality of anchoring points for the downhole tool in the well;    connecting the downhole tool to a running tool and running the assembly into the well;    providing a selectivity feature to the running tool so that the running tool can obtain support selectively near said plurality of the anchoring points;    supporting the running tool from near one of the anchoring points;    anchoring the downhole tool to an anchoring point; and    releasing the running tool from the downhole tool.    
     
     
         12 . The method of  claim 11 , comprising: 
 providing an indexing point adjacent each anchoring point;    retaining an indexing dog to the running tool when the running tool is moved in a first direction and releasing said indexing dog for support of the running tool at an indexing point when the running tool is moved in a second direction opposite said first direction.    
     
     
         13 . The method of  claim 12 , comprising: 
 shifting a sleeve to align an opening opposite said indexing dog to allow it to be biased out from the body of the running tool; and    locking said sleeve to the running tool body when its opening is aligned with said indexing dog.    
     
     
         14 . The method of  claim 12 , comprising: 
 positioning an anchoring dog on the downhole tool adjacent an anchoring point when said indexing dog suspends the running tool from an indexing point; and    locating said anchoring dog into said anchoring point with movement of a portion of said running tool relative to another portion suspended from said indexing point.    
     
     
         15 . The method of  claim 14 , comprising: 
 providing an inner and outer sleeve on the downhole tool;    creating relative movement between said sleeves from said movement of a portion of the running tool; and    using a ramp on one of said sleeves for said locating said anchoring dog through an opening in the other of said sleeves.    
     
     
         16 . The method of  claim 15 , comprising: 
 connecting a first dog on said running tool to said inner sleeve and a second dog on said running tool to said outer sleeve;    releasing said first and second dogs as a result of said relative movement.    
     
     
         17 . The method of  claim 16 , comprising: 
 providing a breakable connection to one of said inner and outer sleeves;    applying a force to said running tool with said anchoring dog located into said anchoring point and said first and second dogs released;    using resistance to said force to the running tool as a signal said anchoring dog is in place in said anchoring point; and    breaking said breakable connection.    
     
     
         18 . The method of  claim 16 , comprising: 
 moving one of said first and second dogs, when said dogs are still connected to said sleeves, with respect to the other of said first and second dogs;    presenting grooves opposite said first and second dogs after said anchoring dog is located into said anchoring point; and    locking said inner and outer sleeves to each other after said anchoring dog is located into said anchoring point.    
     
     
         19 . The method of  claim 15 , comprising: 
 providing said opening in said outer sleeve and said ramp on said inner sleeve;    holding said outer sleeve while moving said inner sleeve;    locking said sleeves to each other after said ramp has pushed said anchoring dog into the anchoring point through said window.    
     
     
         20 . The method of  claim 19 , comprising: 
 connecting a first dog on said running tool to said inner sleeve and a second dog on said running tool to said outer sleeve;    releasing said first and second dogs as a result of said relative movement.    
     
     
         21 . The method of  claim 11 , comprising: 
 using one of coiled tubing and a workstring to run the assembly into the well; and    setting hydraulically at least one of the running tool and the downhole tool.
