Abstract
An adaptor kit is configured to limit the amount of shear pins/metal/material left downhole after the frac plug is set and the setting tool is removed from the hole. More specifically, embodiments may utilize a setting sleeve that is configured to set the frac plug.
Claims18
A downhole tool comprising:
- a conveyed object having a mandrel with an inner diameter profile, an inner diameter of the mandrel having first threads;
- a collet having a proximal end and a segmented distal end, the outer diameter of the collet having second threads, the distal end defining an outer diameter profile configured to engage the inner diameter profile of the mandrel in a radially expanded condition and to disengage from the inner diameter profile in a radially collapsed condition, and a cavity between the proximal end and the distal end, the cavity including a ledge;
- a support sleeve extending within the collet and having a projection on an outer diameter thereof, the projection having an outer diameter greater than an adjacent outer diameter of the support sleeve;
- wherein, in a run-in position, the projection is aligned with the distal end of the collet and props the distal end radially outward into the expanded condition such that the second threads threadably engage the first threads and supports the conveyed object;
- and
- wherein, the conveyed object is configured to be transitioned into a release position by moving the support sleeve relative to the collet, wherein the projection is received in the cavity and positioned adjacent to the ledge such that the distal end of the collet is free to radially collapse into the collapsed condition with an outer diameter less than the inner diameter profile of the mandrel, and further configured such that axial movement of the support sleeve in the release position causes the projection to bear against the ledge to pull the collet uphole while the conveyed object remains downhole.

A method associated with a downhole tool, the method comprising:
- conveying a conveyed object having a mandrel with an inner diameter profile, the inner diameter of the mandrel having first threads, into a wellbore;
- providing a collet having a proximal end and a segmented distal end, the outer diameter of the collet having second threads, the distal end defining an outer diameter profile configured to engage the inner diameter profile of the mandrel in a radially expanded condition and to disengage from the inner diameter profile in a radially collapsed condition, and a cavity between the proximal end and the distal end, the cavity including a ledge;
- providing a support sleeve extending within the collet and having a projection on an outer diameter thereof, the projection having an outer diameter greater than an adjacent outer diameter of the support sleeve;
- positioning the support sleeve relative to the collet in a run-in position such that the projection aligns with the distal end of the collet and props the distal end radially outward into the expanded condition, whereby the second threads threadably engage the first threads and support the conveyed object;
- moving the support sleeve relative to the collet to a release position after the conveyed object is set, such that the projection is received in the cavity and positioned adjacent the ledge, whereby the distal end of the collet is free to radially collapse into the collapsed condition with an outer diameter less than the inner diameter profile of the mandrel;
- and
- axially moving the support sleeve in the release position to cause the projection to bear against the ledge and pull the collet uphole while the conveyed object remains downhole.
