Popular Name：Quick Test Sub / Fast Test Sub / QTS
Quick Test Sub ( QTS ) saves rig time when it’s necessary to make and break the Lubricators to install and remove the Tool String several times.
Normally, Quick Test Sub is inserted above the Wireline BOP at the position of the joint usual opened to insert and retrieve tools from the well. After making the first pressure test to check the integrity of the whole Wireline PCE String, subsequent pressure tests can be made using the Quick Test Sub to verify the integrity of the joint disconnected, rather than having to test the whole assembly.
With the Quick Test sub, the connection that is broken can be retested by pressure testing the space between the two O-ring Seals on the Quick Test Sub. This is a small volume and can be pressured up quickly with a Hydraulic Hand Pump from the outside.
A high pressure Hand Pump and 100ft Testing Hose are normal required with the Quick Test Sub no matter Grease and Hydraulic Control Module provided or not.
