Downhole tool and method of use

Abstract

A downhole tool suitable for use in a wellbore, the tool having a cone mandrel having a dual-cone outer surface. The downhole tool includes a carrier ring disposed around one end of the cone mandrel. There is a slip disposed around or proximate to an other end of the cone mandrel. The cone mandrel has inner flowbore extending therethrough from the proximate end to the distal end.

       wherein the downhole tool has a set position and an unset position, and 
       wherein in each of the set position and the unset position, the ball seat is relatively disposed between the location of the carrier ring and the slip. 
     
     
         2 . The downhole tool of  claim 1 , wherein the ball seat is defined by a first portion of the inner flowbore having a first inner diameter smaller than another portion of the inner flowbore having a second inner diameter, and wherein the first inner diameter of the first portion between the ball seat and the distal end is constant. 
     
     
         3 . The downhole tool of  claim 1 , wherein the first angle is in a first angle range of 5 degrees to 10 degrees. 
     
     
         4 . The downhole tool of  claim 1 , wherein the slip comprises an at least one slip groove that forms a lateral opening in the slip 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 a slip outer surface to a slip inner surface. 
     
     
         5 . The downhole tool of  claim 4 , wherein when the downhole tool is in the set position or the unset position, the carrier ring comprises an underside surface entirely in contact with the outer surface. 
     
     
         6 . The downhole tool of  claim 5 , wherein any component of the downhole tool is made of a dissolvable metal-based material. 
     
     
         7 . The downhole tool of  claim 1 , wherein the carrier ring comprises an underside surface entirely in contact with the outer surface. 
     
     
         8 . The downhole tool of  claim 1 , wherein the lower sleeve comprises a shear tab, and wherein a longitudinal length of the downhole tool after being moved to the set position is in a set length range of at least 5 inches to no more than 15 inches. 
     
     
         9 . The downhole tool of  claim 8 , wherein the ball seat is defined by a first portion of the inner flowbore having a first inner diameter smaller than another portion of the inner flowbore having a second inner diameter. 
     
     
         10 . The downhole tool of  claim 9 , wherein the first angle has a first angle range of 5 degrees to 10 degrees. 
     
     
         11 . A downhole tool for use in a wellbore, the downhole tool comprising:
 a cone mandrel comprising:
 a distal end; a proximate end; an outer surface; an inner flowbore extending through the cone mandrel from the proximate end to the distal end; and a ball seat in the inner flowbore, 
   a carrier ring slidingly engaged with the proximate end;   a slip engaged with the distal end; and   a lower sleeve coupled with the slip,   
       wherein the outer surface comprises a first angled surface and a second angled surface, 
       wherein the first angled surface comprises a first plane that in cross section bisects a longitudinal axis at a first angle having a first angle range of 5 degrees to 10 degrees, 
       wherein the second angled surface comprises a second plane that in cross section bisects the longitudinal axis at a second angle that is negative to that of the first angle, 
       wherein the downhole tool has a set position and an unset position, 
       wherein the first angled surface and the second angled surface converge at a crest, 
       wherein with respect to a lateral the crest has a crest wall thickness greater than each of a furthermost distal end wall thickness and a furthermost proximate end wall thickness, and 
       wherein in each of the set position and the unset position, the ball seat is relatively disposed between the location of the carrier ring and the slip. 
     
     
         12 . The downhole tool of  claim 11 , wherein the slip comprises an at least one slip groove that forms a lateral opening in the slip that is defined by a first portion of slip material at a first slip end, and a depth that extends from a slip outer surface to a slip inner surface. 
     
     
         13 . The downhole tool of  claim 12 , wherein any component of the downhole tool is made of a dissolvable metal-based material.
