ABSTRACT:
A test technique and mechanism includes lowering a junction assembly to a junction between at least two bores of a well. The junction assembly includes one or more sealed connections that are tested by the generation of a test flow of fluid. The distal ends of the junction assembly are blocked so that a pressure increase in the junction assembly can be monitored. The level of this pressure increase is used to determine if there is any leakage in the junction assembly. To reduce the costs associated with a faulty junction assembly, the testing is performed during an installation procedure of the junction assembly. Thus, if a faulty junction is detected, it can be quickly removed and replaced with another junction assembly.
