Abstract
A wet connection system has pressure compensation operative when running in and thermal effects compensation active in the duration between running in and supporting a bottom hole assembly and hooking up a production string having a mating upper part of the wet connect to the lower part of the wet connect already in the hole. The thermal compensation system is then defeated by locking a floating piston so that applied pressure in a given control line will be used to operate an associated tool connected to that control line. Multiple control lines each similarly compensated are envisioned. The pressure compensation system comes out of the hole with the running tool for the bottom hole assembly.
