Abstract: A liner hanger having one: or more enhanced Socking assemblies is provided. The liner hanger includes a liner hanger body, lower slips, upper slips, a packer cone, and a seal that seals an annulus between the liner hanger and an outer casing, The one or more enhanced locking assemblies may include: a packer cone locking assembly that prevents all components of the liner hanger from actuating until it is unlocked; a slips locking assembly that prevents the lower slips from being actuated until it is unlocked; guide rails that prevent. the lower slips and/or the upper slips from being wedged in a radially outward direction during run in; and a floating cone locking assembly that releases the packer cone from being coupled to a spacer of the liner hanger when it is unlocked.

Abstract: A downhole plug for plugging a tubular member. The downhole plug may include a packer and a slip assembly including a plurality of slip segments circumferentially spaced about a central axis of the slip assembly, each slip segment having a body comprising a first end, a second end longitudinally opposite the first end, an outward face with at least one engagement member for coupling to the tubular member, and sides each facing an adjacent slip segment of the plurality of slip segments. The plurality of slip segments may include a first set of slip segments and a second set of slip segments wherein each of the first set of slip segments is positioned directly between a pair of the second set of slip segments. Each of the second set of slip segments may include a pair of arcuately extending anti-extrusion members.

Abstract: A self-locking packer carrier includes an integrated locking mechanism that locks the packer carrier directly to the packer cone after the sealing element is fully set. The integrated locking mechanism may include one or more compression splines extending from a packer carrier base in a radially outward direction to engage a casing after the attached sealing element has created a fluid tight seal, and a tooth profile formed along an inner diameter of the packer carrier base to lock the packer carrier to the packer cone in response to a compression force transferred to the base via the splines. The integrated locking mechanism is designed to eliminate backlash on the liner hanger system, increase vibrational resistance, accommodate liner stretch, withstand pump-out loads, and tolerate liner movement while maintaining sealing integrity.

Abstract: An improved c-ring slip retention system and method for extraction of the c-ring slip are provided. The c-ring slip retention system may use a lip portion of a retention sleeve to hold the c-ring slip against a liner hanger body. The c-ring slip may have a multi-load shoulder profile that interfaces directly with a complementary profile formed in the liner hanger body. The disclosed retention system prevents the c-ring slip from being prematurely extracted from a liner hanger body while the liner hanger is lowered through a borehole. The c-ring slip retention system may include a first retention mechanism and a second retention mechanism used to secure the retention sleeve to the liner hanger body. A single actuation of at least one setting segment in an axial direction may disengage both retention mechanisms, move the retention sleeve axially relative to the liner hanger body, and extract the c-ring slip.

Abstract: An improved c-ring slip retention system and method for extraction of the c-ring slip are provided. The c-ring slip retention system may use an axially movable support sleeve with a support ring for securing the c-ring slip against a retention lip of the liner hanger body. The disclosed retention system prevents the c-ring slip from being prematurely extracted from a liner hanger body while the liner hanger is lowered through a borehole. The c-ring slip retention system may also include anti-rotation features that prevent the c-ring slip from rotating relative to the liner hanger body. A single actuation of the support sleeve in an axial direction may unlock the c-ring slip from the retention lip, disengage the anti-rotation features, compress the c-ring slip out of the keyed profile, and extract the c-ring slip from the liner hanger body.
