Plug securement and running arrangement and method

Abstract

A plug securement and running arrangement including a wireline adapter kit having a tension mandrel, a setting tool attached to the wireline adapter kit, a collet configured and dimensioned to be received in a bore of a downhole plug and having a material-penetrating engagement feature on an outer surface thereof attached to the tension mandrel, an interengagement feature interengaging the tension mandrel and the collet, and a support surface extending from the interengagement feature and disposed radially inwardly of the feature. A method for deploying a plug in a borehole system including penetrating an inside surface of a plug with a material-penetrating feature of a collet, setting the plug at a target location in the borehole system, disengaging the material-penetrating feature from the plug.

What is claimed is: 
     
         1 . A plug securement and running arrangement comprising:
 a wireline adapter kit having a tension mandrel;   a setting tool attached to the wireline adapter kit;   a collet configured and dimensioned to be received in a bore of a downhole plug and having a material-penetrating engagement feature on an outer surface thereof attached to the tension mandrel;   an interengagement feature interengaging the tension mandrel and the collet; and   a support surface extending from the interengagement feature and disposed radially inwardly of the feature.   
     
     
         2 . The arrangement as claimed in  claim 1  wherein the support is a shaft. 
     
     
         3 . The arrangement as claimed in  claim 1  wherein the collet further includes flats along each side of each collet finger. 
     
     
         4 . The arrangement as claimed in  claim 3  wherein the interengagement feature includes reduction fins. 
     
     
         5 . The arrangement as claimed in  claim 4  wherein the reduction fins are configured to interact with the flats to draw the collet fingers radially inwardly when the interengagement feature is stroked. 
     
     
         6 . The arrangement as claimed in  claim 4  wherein the reduction fins comprise a radially extending web and a flange. 
     
     
         7 . The arrangement as claimed in  claim 6  wherein the flange includes an interface surface for a flat of the flats, the interface surface being closer to an axis of the interengagement feature distal to the tension mandrel and farther away from the axis of the interengagement feature proximal to the tension mandrel. 
     
     
         8 . The arrangement as claimed in  claim 1  wherein the material-penetrating engagement feature is a wicker. 
     
     
         9 . The arrangement as claimed in  claim 1  wherein the collet is cylindrical at rest. 
     
     
         10 . The arrangement as claimed in  claim 1  wherein the collet is frustoellipsoidal when at rest. 
     
     
         11 . The arrangement as claimed in  claim 1  wherein the collet includes a release configuration releasably connecting the collet to the tension mandrel. 
     
     
         12 . The arrangement as claimed in  claim 1  wherein the collet includes a cap. 
     
     
         13 . The arrangement as claimed in  claim 12  wherein the cap includes a release configuration releasably retaining the cap and the tension mandrel. 
     
     
         14 . A method for deploying a plug in a borehole system comprising:
 penetrating an inside surface of a plug with a material-penetrating feature of a collet;   setting the plug at a target location in the borehole system;   disengaging the material-penetrating feature from the plug.   
     
     
         15 . The method as claimed in  claim 14  wherein the disengaging is withdrawing a shaft previously forcing the material-penetrating feature into the plug. 
     
     
         16 . The method as claimed in  claim 14  wherein the disengaging is drawing reduction fins into the collet to forcibly radially reduce the collet.
