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.
Claims39
A downhole tool, comprising:
- a single frustoconical member forming a first end of the downhole tool;
- a single engagement collar forming a second end of the downhole tool opposite the first end when the downhole tool is introduced into a wellbore;
- a single set of slips arranged concentrically to form an external surface of the downhole tool, wherein the set of slips are in contact with the engagement collar;
- a single elastomeric element located between the set of slips and the frustoconical member, wherein at least a portion of the elastomeric element substantially surrounds a portion of the frustoconical member;
- and
- wherein the downhole tool is enabled for setting in the wellbore by applying a setting force to the engagement collar against 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 wellbore,
- wherein the downhole tool is enabled for setting in the wellbore by applying the setting force to the engagement collar against the set of slips using a wireline adapter kit,
- wherein the wireline adapter kit is enabled to engage the frustoconical member at the first end and to engage the engagement collar, including the wireline adapter kit enabled to engage the engagement collar using at least one shear pin that shears when a predetermined force is applied to the shear pin,
- wherein the setting force is greater than a product of the predetermined force multiplied by a number of shear ins engaging the engagement collar.

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 engagement collar at a second end of the downhole tool opposite the first end when the downhole tool is introduced into a casing of a wellbore;
- 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 engagement collar;
- and
- a single elastomeric element located 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 the engagement collar against 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,
- wherein applying the setting force further comprises applying the setting force to the engagement collar against the set of slips using a wireline adapter kit, the wireline adapter kit engaging the frustoconical member at the first end and engaging the engagement collar,
- wherein the setting force is greater than a product of the predetermined shear force multiplied by a number of shear pins engaging the engagement collar.

- a single elastomeric element located between the set of slips and the frustoconical member, wherein at least a portion of the elastomeric element substantially surrounds a portion of the frustoconical member;
- and
- wherein the downhole tool is enabled for setting in the wellbore by applying a setting force to the engagement collar against 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 wellbore,
- wherein the frustoconical member further comprises a central opening in fluid communication with the wellbore when the downhole tool is set,
- wherein the engagement collar is released from the downhole tool when the downhole tool is set, wherein a length of the downhole tool is from the first end to an end of the set of slips, and wherein a first ratio of the length to an external diameter of the downhole tool is less than 1.1 when the downhole tool is set in the wellbore.
