Abstract
A slip and cone arrangement including a mandrel having a groove, the groove having a run in end and a set end, a deepest portion of the groove on the run in end having a distance from a longitudinal axis of the mandrel that is less than a deepest portion of the groove on the set end; and a slip disposed in the groove, the slip having a radially inward surface having a convex portion in nested contact with the groove.
Claims14
A slip and cone arrangement comprising:
- a mandrel having a groove, the groove having a run in end and a set end, a deepest portion of the groove on the run in end having a distance from a longitudinal axis of the mandrel that is less than a deepest portion of the groove on the set end;
- and
- a slip disposed in the groove, the slip having a radially inward surface having a convex portion in nested contact with the groove.
A slip and cone arrangement comprising:
- a mandrel having a cone exhibiting a frustoconical outside surface and exhibiting a smooth curved concave groove therein, the groove being frustoconically oriented relative to a longitudinal axis of the mandrel;
- and
- a slip having a radially inward surface being convex and complementary to the concave groove.
A slip comprising:
- an outside surface a mandrel;
- having a convex curvature;
- and
- a radially inward surface including a portion that is convex and complementary to a cone exhibiting a groove being frustoconically oriented relative to a longitudinal axis of a mandrel with which the slip is to be nested during use.
