Casing cleaning tool
Provides effective wellbore cleanup.
Validation that all debris has been removed from the wellbore when transitioning from drilling to completion operations. Previously, validity testing was performed by measuring the turbidity and solids content of the returning clear brine fluid. The WELL PATROLLER validation tool confirms the effectiveness of the displacement operation by filtering wellbore fluids while tripping.
The WELL PATROLLER validation tool does not require balls or darts to operate. Simply run the tool in and out of the hole in combination with the casing cleaning tool assembly. The goal is for the WELL PATROLLER tool to return to the surface empty or with minimal debris. In case of unforeseen circumstances, rupture discs that relieve pressure automatically activate in the event the tool becomes completely full of debris.
Used specifically in precompletion and drill stem test cleanups, the WELL PATROLLER tool can also be included in drilling and milling strings. All common casing sizes and liner sizes can be accommodated.
Experts discuss removing wellbore debris and replacing solids-laden drilling fluid with a clean brine to prepare for completion operations and hydrocarbon production.
Recovery facilitated the successful running and setting of liner hanger, offshore UK.
Three cleanup tools showed no drilling mud after displacement, proving excellent performance in one drillstring trip, deepwater Gulf of Mexico.
