Trip

A term that is used by pressurized water reactors for a reactor scram (see Scram).

Coiled Tubing: The event which describes the complete deployment and retrieval of a segment of coiled tubing. Specifically, a trip occurs when an identified point on the coiled tubing string (originally on the service reel) is spooled off, deployed below the stripper into the wellbore and subsequently retrieved back onto the reel. Jointed Tubing: The event which describes the complete deployment and retrieval of a string of jointed tubing. Specifically, a trip occurs when an identified point on the tubing string is deployed into the wellbore and subsequently retrieved back to surface.
