Liner hanger systems
Enhance well stability and protect the casing.
Liner top packer with or without hold-down slips
The integral setting adaptor and mandrel design permits the transmission of high torque from the running string to the liner. This feature is used to drill down the liner while it is being run in hole. When a rotational hanger is deployed, the liner can be rotated after the liner hanger is set to improve cement integrity. Optimized design and materials maximize mandrel performance criteria such as burst, collapse, torque, and tensile ratings.
The hold-down slips are optional components that can be added to the PV-3 packer. The design ensures weight is evenly distributed around the supporting casing ID, and is typically used to accommodate high capacity requirements. Hold-down slips are protected from damage by the body of the packer while running into the well. Their recessed configuration also provides a larger fluid bypass area.
