Brief

The Full bore tension safety joint is an optional emergency backoff device. The safety joint releases the workstring and tools above the packer if the packer becomes stuck during operations. The design of the RTTS safety joint makes unintentional operation difficult.


The Full Bore Tension Safety Joint is a two stage disconnect tool which is run above the packer that allows the tubing to be disconnected from the tool string below it should the need arise. The tension safety joint first requires a predetermined tensile load to be applied from surface in order to sever the shear ring assembly which initiates the disconnection. The tensile load required to shear is dependent of specific requirements and ranges from 4,000 to 66,000 pounds (this figure includes the weight of the test string below the tension safety jont). The second stage of disconnection requires right hand torque to be applied to the tubing while simultaneously stroking it vertically approximately nine inches.

Features

• Positive sequence of operation helps prevent premature release.

• Tools above it can be retrieved when string is stuck.
