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.

Introducing, “The PBL Booster Tool”

DSI FZE is pleased to introduce a new option for splitting the flow while drilling, completion and workover operations. With a single ball activation/de-activation cycle a pre-calculated amount of drilling or completion fluid will pass through the Booster Tool and on to the BHA below while the remaining fluid is diverted out of the Booster Tool ports. The ability to split the flow gives the operator more options on available hydraulics and hole cleaning parameters.
