Coiled Tubing In-Situ Pressure Test Sub
Takes the place of the bottom connection, effectively becoming the tool change joint that has to be broken
The Hunting In-Situ Pressure Test Sub was originally designed to reduce time spent pressure testing the broken lubricator connection after tool changes.
The Coiled Tubing In-Situ Pressure Test Sub takes the place of the bottom connection, effectively becoming the tool change joint that has to be broken. As a result of its unique design, it can be tested in isolation to the rest of the rig-up, by the simple use of a small hand pump.
The mid-joint of a Coiled Tubing In-Situ Pressure Test Sub is like any other quick union, except that it has two O-ring seals with a pressure test port between them. This feature is responsible for easy testing of joint integrity.
As noted, this saves pressure testing the whole rig-up, however there is another added advantage in that it allows for the riser system to be pressure tested whilst pressure sensitive equipment (such as perforating guns) are in the riser.
