Abstract
A frac plug with lower slips and a lower cone. In embodiments, a lower cone ramp angle is greater than or equal to a cone bevel angle and a slip inner cut angle. This geometry enables the fins of the cone to not interact with the lower slips, which may not break the lower slips as the lower slips move over the cone. Instead, the lower slips may break due to stresses caused by the tendency of the lower slips to expand as they lower slips interact with the ramp of the lower cone.
Claims19
A downhole tool comprising:
- a slip with a plurality of wedges and webbing, the webbing being positioned between the plurality of wedges, wherein after setting the slip at least a fin of a cone is configured to be radially positioned between an inner surface of the webbing and a central axis of the downhole tool without contacting an inner surface of the webbing, the fin extending outward from an outer surface of the cone.
A downhole tool comprising:
- a slip with a plurality of wedges and webbing, the webbing being positioned between the plurality of wedges, wherein after setting the slip at least a portion of a cone is configured to be positioned radially between an inner surface of the webbing and a central axis of the downhole tool without contacting an inner surface of the webbing,
- wherein before setting the slip at least the portion of the cone is positioned radially between an inner surface of the webbing and a central axis of the downhole tool without contacting an inner surface of the webbing.
A downhole tool comprising:
- a slip with a plurality of wedges and webbing, the webbing being positioned between the plurality of wedges, wherein after setting the slip at least a portion of a cone is configured to be positioned radially between an inner surface of the webbing and a central axis of the downhole tool without contacting an inner surface of the webbing,
- a cap positioned downhole from the slip, wherein the cap and the slip include anti-rotation mechanisms that do not allow the relative rotation between the cap and the slip.
