A triple-sealed ESP connection provides a first seal at the upper end of a coiled tubing to limit the migration of vapors from the interior of the coiled tubing into the annulus at a wellhead and a second seal to prevent migration of the vapors from the annulus of the wellhead to the exterior surface of the wellhead. This triple-sealed arrangement can be accomplished by providing a threaded connection on an upper end of the coiled tubing to which is attached the sealable shroud for the electrical conductor splice which sealably connects with the wellhead thereby providing a sealed upper end to the coiled tubing and a second seal on the shroud and a seal at the wellhead. The second seal in both cases is the seal that can be either a metal-to-metal or other type of compressive seal arrangement or a sealed tubing arrangement.
