Test Sub

Test Sub

The test sub SNLEE distributes is developed to save rig time while pressure testing the wireline pressure control equipment string when multiple wireline runs are required.

The sub makes it easy to make changes to a tool string during multiple runs. It maintains wireline stack integrity and allows an operator to solely re-test the separated connection instead of the entire string.

The sub is inserted either above or below the wireline valve at the position of the joint which is normally opened to insert and retrieve tools from the well. After performing the first pressure test to check the integrity of the whole string, subsequent pressure tests can be made using the quick test sub. This allows for verification of joint integrity with it disconnected, rather than having to test the whole assembly.
