Abstract

A compact downhole tool, such as a frac plug, may include a single frustoconical member and a single set of slips. The slips may further include an internal button that engages with the frustoconical member. Various elements in the downhole tool may be dissolvable or degradable.

Claims (15)

1 . 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.

2 . The method of claim 1 , further comprising:

introducing into the wellbore a sealing element configured to engage a central opening in the downhole tool.

3 . The method of claim 2 , further comprising:

causing the sealing element to dissolve in the wellbore; and

producing hydrocarbons from the wellbore through the central opening after the sealing element has dissolved.

4 . The method of claim 1 , wherein the step of applying a setting force is performed using a wireline adapter kit.

5 . The method of claim 1 , wherein at least one slip of the plurality of slips is formed using a composite material.
