Abstract
A slip for use in a downhole tool that includes internal buttons on an internal surface of the slip that engages a setting cone. The internal buttons may be made of a hard material, such as a ceramic, among others, to increase the coefficient of friction between the slip and the cone when the downhole tool is set.
Claims35
A slip, comprising:
- an outer surface enabled to engage a wellbore surface;
- and
- an inner surface enabled to be engaged by a setting cone of a downhole tool, wherein the inner surface includes at least one inner button enabled to contact the setting cone when the setting cone engages the inner surface.
A downhole tool, comprising:
- a setting cone enabled to engage a plurality of slips located circumferentially about the setting cone when the downhole tool is set;
- and
- wherein the slips further comprise:
- an external surface enabled to engage a casing when the downhole tool is set;
- and
- an internal surface enabled to engage the setting cone when the downhole tool is set;
- wherein at least one of the slips further comprises:
- the internal surface of the slip including at least one internal button enabled to contact the setting cone when the downhole tool is set.

A method for engaging downhole tools in wellbores, the method comprising:
- running a downhole tool to a depth in a casing, wherein the downhole tool comprises a setting cone enabled to engage a plurality of slips located circumferentially about the setting cone when the downhole tool is set;
- setting the downhole tool in the casing, including causing the plurality of slips to engage a setting cone, the slips further comprising:
- an outer surface enabled to engage the casing when the downhole tool is set;
- and
- an inner surface enabled to engage the setting cone when the downhole tool is set;
- wherein at least one of the slips is an inner button slip further comprising:
- the inner surface of the slip including at least one inner button;
- and
- wherein causing the plurality of slips to engage the setting cone further comprises:
- forcing the plurality of slips against the setting cone;
- and
- wherein the plurality of slips include the at least one inner button slip, and wherein the inner button contacts the setting cone as the plurality of slips engage the casing.
