Quick Test Sub

Quick Test Sub

Quick Test Sub is designed to save rig time while pressure testing a lubricator rig up, before exposing it to well pressure. When multiple wireline runs are required, the lubricator has to be tested each time the bottom connection is broken, and much time can be lost. After performing the first pressure testing of the whole string, subsequent pressure test can be made using the Quick Test Sub to verify the integrity of the joint disconnected, rather than testing the whole lubricator assembly. This is done by connecting a small hand pump to the Quick Test Sub and testing the two O-Rings seals from outside. The Quick Test Sub s installed either above or below the BOP and becomes the joint that is disconnected each time to insert and retrieve tools from the well.
