Weatherford’s adjustable sub with rotational lock enables the length of the
tubing to be adjusted up to 24 in. (610 mm) without rotation of the tubing
string. The sub is used in multistring completions to ease connecting or
spacing the tubing among multiple packers and the tailpipe. The lock
prevents both telescoping and rotation.
Applications
• Multistring completions
• Retrievable packer systems
Features, Advantages and Benefits
• The sub can be locked at any length up to 24 in. (610 mm) to facilitate
tubing connections and spacing among multiple retrievable packers,
reducing the inventory of pup joints required.
• The rotational lock prevents the rotation and telescoping of the tubing
string to enable the correct operation of downhole equipment.
