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 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.

Abstract: A hybrid-tieback seal assembly and methods for tying a well back to the surface or subsea well head are disclosed. A method to tie a well back to the surface or subsea well head comprises running a hybrid-tieback seal assembly into a wellbore, the hybrid-tieback seal assembly comprising one or more anchoring bodies, one or more packer seal assemblies; and a device for creating a pressure differential in a tieback string, wherein the tieback string is coupled to the hybrid-tieback seal assembly. The method further comprises landing a casing hanger in a well head, increasing pressure in the tieback string, setting the anchoring bodies and one or more packer seal assemblies within at least one of a previously installed liner hanger system and a host casing above a previously installed hanger system, and testing the hybrid-tieback seal assembly down an annulus between the host casing and the tieback string.

Abstract: Hybrid-tieback seal assemblies, interventionless setting assemblies, and associated methods of setting downhole components of the hybrid-tieback seal assemblies using such interventionless setting assemblies are disclosed. A hybrid-tieback seal assembly comprises one or more anchoring bodies, one or more packer seal assemblies, and one or more interventionless hydraulic setting systems. A method of setting downhole equipment comprises applying a pressure to a compensating volume and providing a working volume, wherein the working volume is separated from the compensating volume by one or more hydraulic control devices. A pressure is applied to the working volume in response to the pressure applied to the compensating volume. The pressure applied to the compensating volume is then reduced and the pressure applied to the working volume is captured by the hydraulic control devices. The captured pressure in the working volume is applied to set one or more of the anchoring bodies and packer seal assemblies.
