Subsurface safety

Baker Hughes has a new tubing retrievable, subsurface safety valve for ultra deep-set, deepwater and HPHT applications. The REACH subsurface safety valves can be set as deep as 20,000ft and ensure fail-safe-closed operation using reliable, field-proven, heavy sprung closure technology, according to the service company.

The new valve offers a single control line operating system for deepwater HPHT wells. It can be controlled from the surface, allowing personnel to monitor its operation remotely. The valve's design isolates wellbore tubing pressure from the hydraulic operating control system, which enables the opening of the valve at much lower operating pressure than previous heavy-sprung valves.

A nitrogen charge system is not necessary. This feature makes the REACH valve ideal for applications with opening pressure limitations, such as subsea completions, high-pressure wells and fields where the rig site and other control facilities may have supply pressure capability limitations, the company says.
