Abstract
A jet bushing for a wellbore cleanup tool features a jet looking uphole to reduce turbulence at the outlet ports that look downhole to accommodate the recirculation flow around the tool that captures the cuttings. The uphole oriented port keeps the pumped fluid downhole from having to make a u-turn to get back uphole and reduces turbulence to allow a higher recirculation flow at the tool to pick up and capture cuttings within the tool.
