Abstract
A downhole tool includes a cone, a slips assembly positioned at least partially around the cone, and a shoe configured to press against the slips assembly. The shoe is configured to engage a setting assembly, so as to apply an axial force to the slips assembly that moves the slips assembly relative to the cone and drives the slips assembly radially outwards. The shoe is made at least partially from a dissolvable material configured to dissolve in a fluid in a well, and the cone, the slips assembly, or both are at least partially made from a second material that is configured not to dissolve in the fluid in the well.
Claims20
A method, comprising:
- connecting a setting assembly to a downhole tool comprising a slips assembly, a cone positioned at least partially in the slips assembly, and a shoe;
- deploying the downhole tool and the setting assembly into a well;
- attempting to set the downhole tool in the well using the setting assembly;
- determining that attempting to set the downhole tool is unsuccessful;
- withdrawing the setting assembly from the well while leaving the downhole tool in the well, wherein the shoe dissolves in a fluid in the well in response to determining that attempting to set the downhole tool is unsuccessful;
- and
- drilling out the slips assembly, the cone, or both after dissolving the at least a portion of the shoe.
A method, comprising:
- running a downhole tool into a well, wherein the downhole tool comprises a cone;
- setting the downhole tool in the well;
- and
- introducing an impediment into the well, wherein the impediment is received into a seat formed on an inner surface of the cone, which causes the cone to deflect radially inwards and to yield or collapse, thereby unsetting the downhole tool in the well.
A method, comprising:
- deploying a downhole tool into a well, wherein the downhole tool comprises a slips assembly and a cone positioned at least partially in the slips assembly;
- deploying a first impediment into a first seat of the cone of the downhole tool;
- increasing a pressure in the well uphole of the downhole tool, wherein the pressure generates an axial force on the cone at least partially via the first impediment, and wherein the first impediment prevents at least a portion of the cone from deforming radially inward;
- deploying a second impediment to a second seat of the cone of the downhole tool, such that the second impediment is held by engagement with the second seat, wherein the second seat is uphole of the first seat;
- and
- increasing a pressure in the well uphole of the downhole tool, wherein the pressure generates an axial force on the cone at least partially via the second impediment, and wherein the axial force drives the cone axially into the slips assembly which causes the cone to deform radially inwards such that the downhole tool is at least partially unset.
