An operator drilling a deepwater well in West Africa wanted to thoroughly clean the 1,500m long lateral section of the hole before running the completion. Because this was an expensive deepwater horizontal well, they needed an effective, highly efficient solution to minimize costs and risks.
The operator worked with the DSI team and
determined that a 6¾ inch OD PBL® Multiple Activation Bypass System would be utilized to clean out the well. The tool would be activated in the horizontal section of the well once TD is reached, then the BHA would be pulled back to the 9⅝ inch liner shoe.
The PBL® Tool was successfully activated and deactivated in the horizontal section of the well. The hole was sufficiently cleaned, the BHA was POOH, and the completion assembly was successfully run to TD.
The PBL® Tool provided the perfect solution to clean the hole without the need for a dedicated trip with a clean-out assembly, hence provided the operator with an efficient solution to minimize costs and risks.
The operator was impressed with the tool’s performance and determined that the PBL® Bypass System would be standard for all future lateral wells.
