During an offshore drilling operation for a major Indian operator, the drill-string became stuck and packed off, with the hole inclination at 60°.
The operator was unable to establish any circulation or rotation and the jars were unable to fire up or down. It was imperative to re-establish circulation as soon as possible in an effort to help free the drill-string.
DSI advised that a Fast Dart should be dropped from surface to the 6 ¾” PBL® circulating sub, which was positioned within the BHA approximately 50m behind the drill-bit. Falling under gravity and without the need to circulate, the Fast Dart successfully landed in the PBL® tool allowing the tool to be activated into the open position and begin attempts to regain circulation.
