The Sliding Sleeve Big Bore (SSBB) System was developed for drilling operations where the retrievability of LWD radioactive sources in the BHA below the SSBB Tool is required.

PBL Tool

Innovated standard tool

Used in exactly the same applications as the standard PBL Tool, the SSBB Tool features a much larger internal ID without any ball catcher cage. This not only allows retrieval from below the SSBB Tool, but also gives an unlimited number of cycles when opening or closing the tool.

Using PBL for Vibration Mitigation

If off bottom high speed string rotation during clean up cycle is a concern (vibrations, tool failures, etc.), a PBL tool can be used as an alternative for achieving the hole cleaning objective. Activating the tool to bypass flow above the BHA will allow for higher flow rate by eliminating the BHA and bit pressure losses. Depending on the hydraulics and ECD limitations, if high flowrate can achieve a turbulent regime across the drill pipe annulus, this can be effectively used to achieve the hole cleaning objective without subjecting the BHA to high speed off bottom rotation, thus preventing any further risk of damage/ failure to the BHA.
