HEAVY-DUTY WELL PATROLLER Tool
HEAVY-DUTY WELL PATROLLER tools were run near the bottom of each of three casing sections during the main displacement, with a 7 3/4-in tool located at 27,684 ft [8,438 m], a 10 1/8-in tool at 23,833 ft [7,264 m], and an 11 7/8-in tool at 8,801 ft [2,683 m].

Zinc bromide was pumped at 12 bbl/min [1,908 L/min], directly displacing the synthetic-base mud. When the displacement was completed and the workstring was pulled out of hole, no drilling mud was observed on any of the cleanup tools, proving excellent displacement.
