11. A method for using a downhole tool, the downhole tool comprising:
a single frustoconical member at a first end of the downhole tool;
a single set of slips arranged concentrically at an external surface of the downhole tool, wherein the set of slips are in contact with the single frustoconical member; and
an elastomeric element around the circumference of the set of slips tending to pull the slips against the frustoconical member;
between the set of slips and the frustoconical member, wherein the method comprises:
running the downhole tool into the casing to a desired location; and
applying a setting force to shear screws in the set of slips, wherein the set of slips engages the frustoconical member and forces the elastomeric element over the frustoconical member, and the set of slips engages the casing, and wherein the frustoconical member and the engagement collar further comprise a central opening in fluid communication with the casing when the downhole tool is set.
