HEAVY-DUTY WELL PATROLLER Tool Removes Debris and Validates Wellbore Cleaning in One Run

已发表: 02/26/2016

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.

背景

To avoid damage to completion equipment and screens and to prevent production-threatening formation damage, an operator needed to ensure that all debris had been removed from a deepwater well with challenging depths, volumes, temperatures, and pressures while transitioning from drilling to completion.
