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,
- wherein the downhole tool is operable to move from a run-in configuration to a set configuration,
- wherein in the set configuration a ball is positioned within the ball seat in a manner to form a first contact point between the ball and directly against the compressible member, and also a second contact point between the ball and directly against the ball seat,
- wherein a convergence gap is formed between the first contact point and the second contact point such that at all times a point of non-contact occurs between the ball and the seat in the convergence gap,
- wherein on a first lateral reference, the ball seat groove comprises a groove midpoint,
- wherein on a second lateral reference, the compressible member has a compressible member midpoint, and
- wherein during a pressurization sequence, the groove midpoint is offset from the compressible member midpoint.
