Abstract
A downhole tool suitable for use in a wellbore, the tool having a mandrel with an inner flowbore extending therethrough from a proximate end to a distal end. There is a ball seat in the inner flowbore, and a groove disposed in the inner flowbore in association with the ball seat. A compressible member is disposed in the groove.
Claims20
A downhole tool for use in a wellbore, the downhole tool comprising:
- a mandrel comprising:
- a distal end;
- a proximate end having a furthermost end;
- an outer surface;
- an inner flowbore extending therethrough from the proximate end to the distal end;
- a ball seat in the inner flowbore;
- a ball seat groove formed in the inner flowbore between the furthermost end and the ball seat;
- and a compressible member disposed in the ball seat groove,
- a first slip disposed around the mandrel;
- a first cone disposed around the mandrel;
- and
- a sealing element disposed around the mandrel;
- wherein the ball seat comprises a seat portion that results in a first inner diameter of a first portion of the inner flowbore differentiated in a size from a second inner diameter of a second portion of the inner flowbore,
- wherein a ball is positioned within the ball seat in a manner to form a first contact point against the ball from the compressible member, and also a second contact point against the ball directly from the ball seat,
- wherein on a first lateral reference, the ball seat groove comprises a groove midpoint,
- wherein on a second lateral reference, the ball has a ball midpoint,
- wherein during a pressurization sequence, the groove midpoint is offset from the ball midpoint, and
- wherein a convergence gap is formed between the first contact point and the second contact point.
