Drills (Pit, Trip, Strip, Choke, Abandon, Diverter)
Well control drills carried out by crewmembers to ensure positive and effective reaction to a well control situation. Pit drill involves recognizing and reacting to a change in pit level. Trip drill involves recognizing and reacting to a kick while tripping. Strip drills allow the crew to practice stripping in or out of the hole. Choke drills allow crewmembers to practice choke operations with the well under pressure. Abandon drills are generally a part of regular rig drill that involves evacuation to a safe position (especially in the case of H2S) or to the lifeboat stations (offshore). Diverter drills allow the rig floor crew to practice diverting procedures and immediately following actions.
