Claims5
A method for using a downhole tool comprising a single frustoconical member, a mandrel collar affixed to a first end of the single frustoconical member, a plurality of slips arranged concentrically around the mandrel collar, and an elastomeric sealing element disposed around the plurality of slips, the method comprising:
- running the downhole tool into a wellbore to a desired location;
- and
- applying a setting force to shear screws disposed in the plurality of slips;
- causing each of the plurality of slips to separate from each other and move radially outward from a central longitudinal axis of the wellbore to engage a casing of the wellbore, such that:
- a first circumferential distance is created between a first one of the plurality of slips and a second one of the plurality of slips;
- a second circumferential distance is created between the second one of the plurality of slips and a third one of the plurality of slips;
- and
- the first circumferential distance is substantially equal to the second circumferential distance;
- and
- causing the elastomeric sealing element to expand radially outward to seal against the casing of the wellbore.
