Claims21
A slip for a downhole sealing device, comprising:
- a plurality of slip segments angularly disposed about a central axis, each slip segment including:
- a plurality of bodies, wherein each body comprises a first end, a second end opposite the first end, a radially outer and extending from the first end to the second end, and a radially inner end extending from the first end to the second end and positioned between the radially outer end and the central axis, and wherein the radially inner end of at least one of the plurality of bodies comprises a first engagement surface, a second engagement surface, and a receptacle;
- a web extending between the plurality of bodies, the web monolithically formed with each of the plurality of bodies;
- a plurality of engagement members molded or cast at least partially within the radially outer end of each of the plurality of bodies;
- and
- an insert received within the receptacle of the at least one of the plurality of bodies, wherein the insert comprises a first planar surface flush with the first engagement surface and a second planar surface that extends at a non-zero angle relative to the first planar surface and which is flush with the second engagement surface;
- wherein each of the slip segments are releasably coupled to one another.

A slip for a downhole sealing device, comprising:
- a plurality of separate and distinct slip segments angularly disposed about a central axis, each slip segment comprising:
- a body formed of a first material, wherein the body comprises an outer surface and an inner surface located between the outer surface and the central axis;
- and
- a first arcuate engagement member and a second arcuate engagement member separate and distinct from the first arcuate engagement member, the first arcuate engagement member and the second engagement member each embedded within the outer surface of the body whereby relative movement between the body and the first arcuate engagement member and the second arcuate engagement member is prevented, and wherein the second arcuate engagement member is formed of a second material that is different from the first material.
1 more element
A method for manufacturing a slip for a downhole sealing device, the method comprising:
- (a) forming a plurality of engagement members from a first material;
- (b) placing the engagement members into a mold;
- (c) inserting a second material into the mold around the engagement members to form a slip segment;
- and
- (d) coupling the slip segment formed during (c) to another slip segment;
- wherein (a) comprises:
- (a1) cutting a plurality of rings from the first material;
- (a2) cutting each ring into a plurality of arcuate segments;
- and
- (a3) cutting one or more grooves into one or more of the arcuate segments.
