Abstract

A downhole system for use in a wellbore that includes a work string having a downhole end; a setting sleeve coupled with the downhole end; and a downhole tool engaged with the setting sleeve during run-in, the downhole tool further including a mandrel, a first slip, a first cone, a sealing element, and a lower sleeve coupled with the mandrel.

a mandrel made of a composite material, the mandrel further comprising:

a distal end; a proximate end comprising a set of threads; and a mandrel outer surface;

a bearing plate disposed around the mandrel;

a first slip disposed around the mandrel proximate to the distal end, the first slip further comprising:

a first slip body having a one-piece configuration;

a first slip outer surface; and

at least one lateral groove in the first slip body that is defined by a depth that extends from the first slip outer surface to a first slip inner surface;

a first cone disposed around the mandrel, and proximate to a first side of the first slip;

a second slip disposed around the mandrel;

a second cone disposed around the mandrel, and proximate to a first side of the second slip;

a sealing element disposed around the mandrel, and between the first cone and the second cone; and

a lower sleeve disposed around the mandrel, and proximate to a second side of the first slip, wherein the lower sleeve is coupled with the mandrel outer surface at the distal end,

wherein the setting sleeve comprises a set of linear channels disposed in an outer surface of the setting sleeve, wherein an at least one channel of the set of channels extends from a first sleeve end to a second sleeve end, and wherein the setting tool comprises an adapter coupled with the set of threads.

2. The downhole system of claim 1 , wherein the distal end is configured with a bottom ball check comprising a check ball held in place by a check ball retainer.

3. The downhole system of claim 2 , wherein the check ball is proximate to a seat contact surface disposed in the mandrel.

4. The downhole system of claim 1 , wherein the downhole tool further comprises a deformable member proximate to the first cone, the deformable member configured to expand outward in a radial direction away from a longitudinal tool axis upon interaction with a pump down fluid.

5. The downhole system of claim 1 , wherein the setting sleeve comprises a plurality of grooves.

6. The downhole system of claim 5 , wherein an at least one channel of the plurality of grooves is linear in length and disposed in an outer surface of the setting sleeve.

7. The downhole system of claim 1 , wherein the first slip is a heat treated one-piece metal slip configured with a hardness profile comprising the first slip outer surface having a Rockwell hardness Scale C (HRC), in the range of 40 to 60, and the inner slip surface having a Rockwell hardness Scale C (HRC) in the range of 10 to 25.

8. The downhole system of claim 1 , wherein the first slip further comprises a slip face surface configured with a set of mating holes, and wherein the lower sleeve comprises a set of pins configured to engage the set of mating holes.

9. The downhole system of claim 1 , wherein the setting sleeve comprises a set of three groups of channels disposed in an outer surface of the setting sleeve, wherein each group comprises between 1 and 3 channels, and wherein the cross-sectional shape of an at least one channel of the set of three groups is rounded.

10. The downhole system of claim 1 , wherein the second slip further comprises:

a composite slip further comprising a circular composite slip body having one-piece configuration, and an at least two slip grooves disposed therein,

wherein the composite slip body further comprises a composite slip outer surface and a composite slip inner surface, wherein at least one of the at least two slip grooves forms a lateral opening in the composite slip body that is defined by a first portion of slip material at a first slip end, a second portion of slip material at a second slip end, and a depth that extends from the composite slip outer surface to the composite slip inner surface.

11. A downhole system for use in a wellbore, the downhole system comprising:

a work string comprising a downhole end, and a setting tool;

a setting sleeve coupled with the downhole end; and

a downhole tool engaged with the setting sleeve during run-in, the downhole tool further comprising:

a mandrel further comprising:

a distal end; a proximate end; and a mandrel outer surface;

a first slip disposed around the mandrel proximate to the distal end;

a first cone disposed around the mandrel, and proximate to a first side of the first slip;

a deformable member proximate to the first cone, the deformable member configured to expand outward in a radial direction away from a longitudinal tool axis upon interaction with a pump down fluid;

a sealing element disposed around the mandrel; and

a lower sleeve disposed around the mandrel, and proximate to a second side of the first slip, wherein the lower sleeve is coupled with the mandrel outer surface at the distal end,

wherein the setting sleeve comprises a set of linear channels disposed in an outer surface of the setting sleeve, wherein an at least one channel of the set of channels extends from a first sleeve end to a second sleeve end, wherein a lateral cross-sectional shape of the at least one channel is rounded, and wherein the setting tool comprises an adapter coupled with the proximate end.

12. The downhole system of claim 11 , the system further comprising a drop ball engaged with the mandrel, wherein the drop ball is made of dissolvable material.

13. The downhole system of claim 11 , wherein the first slip is a one-piece metal slip that comprises columns of serrated teeth.

14. The downhole system of claim 11 , wherein the first slip further comprises:

a composite slip further comprising a circular composite slip body having one-piece configuration, and an at least two slip grooves disposed therein,

wherein the composite slip body further comprises a composite slip outer surface and a composite slip inner surface, wherein at least one of the at least two slip grooves forms a lateral opening in the composite slip body that is defined by a first portion of slip material at a first slip end, a second portion of slip material at a second slip end, and a depth that extends from the composite slip outer surface to the composite slip inner surface.

15. A downhole system for use in a wellbore, the downhole system comprising:

a work string comprising a downhole end, and a setting tool further comprising a setting adapter;

a setting sleeve coupled with the downhole end; and

a downhole tool engaged with the setting sleeve during run-in, the downhole tool further comprising:
