Reduce CAPEX by eliminating the need to run long casing string to surface
Running liners is not without risk. Wellbores take on many characteristics that are often challenging to liner deployment. Wells with high pressure differentials and extreme temperature ranges can threaten tool integrity. This can lead to non-productive time (NPT) which drives up cost. These extreme environments require liner system solutions that can effectively manage the liner to total depth while mitigating risks and withstanding severe conditions.
Liner systems help reduce CAPEX by eliminating the need to extend a single, long casing string to the top of the wellbore. A liner hanger allows the liner (casing below the liner hanger) to be suspended in the previous casing string to reduce material cost and provide completion solution options. A seal is required at the top of the liner hanger to prevent transfer of fluid or pressures from either direction. This seal can be in the form of an integral expandable liner hanger or by means of a liner packer.
Our portfolio of tools offers both expandable and conventional liner hangers to cover all types of well environments from mature and unconventional assets to shallow and ultra-deep water.
