Hole Opener Power Reamer
– The Power Reamer is a hydraulically expandable under-reamer designed to enlarge existing or remaining holes, ensuring a smooth and consistent wellbore.
– Constructed from a one-piece forged body and optimized using FEA and CFD, it offers a robust design while improving hole cleaning efficiency.
– The reamer is activated via ball-dropping or a pre-set central nozzle to control pressure drop. Its Z-pattern grooves ensure reliable and consistent full expansion and retraction.
– The cutting structure can be customized to match drill bit dynamics, delivering optimal performance and reliability in challenging drilling applications.
