A downhole system including tubular casing string and a packer setting joint configured to receive a packer therein. The packer setting joint includes an interior and an exterior, and all interior and exterior surfaces from an uphole to a downhole end of the packer setting joint are machined surfaces. The uphole end of the packer setting joint is connected to the casing string, and the downhole end of the packer setting joint is connected to the casing string. The packer setting joint has a greater burst strength than a burst strength of a casing joint connected to the packer setting joint within the casing string.

Downhole system using packer setting joint and method

A gas storage well with a tubing string that is disposed within a wellbore communicating an underground storage cavern with the surface. A surface controlled subsurface safety and flow control system is provided within the wellbore so that all flow into or out of the well can be shut down rapidly in the event of an emergency. The safety and flow control system features a dual opening-style packer element that provides an annulus seal between the surrounding casing and the tubing string and between the casing and a pup joint that is located within the annulus. Both the tubing string and the pup joint contain surface controlled subsurface safety valves that are capable of quickly shutting off flow through both the flowbore and the annulus. Each valve can be opened or closed independently of the other.
