The GeoproHYDRA™ comes in a PRO version where the entire tool rotates. All GeoproHYDRA™ systems are hydraulically actuated and require fluid circulation to activate. Achievable rotational speeds are in excess of 1000 RPMs in all sizes, while the MPT (multi-purpose tools) designed specifically for through tubing wellbore cleanup operations, with diameter ≤ 3½ inch (88.9 mm), achieve rotational speeds are in excess of 5000 RPMs.
The GeoproHYDRA™ systems comes in two variants: a first generation tool and the newly launched GEN2 systems.
First generation systems are high speed systems, come standard with 6 blades and an aluminium nose and very limited torque. Pressure drop across the system is low with little or no back/stall pressure making the GeoproHYDRA™ the ideal tool for running delicate completions strings through unconsolidated formations where reaming is required.
The GEN2 system significantly extends the torque output by up to 8 times, raising the torque output by the GeoproHYDRA™ to the lower thresholds of the MRS™. This improvement has enabled more cutting structure to be included on the GeoproHYDRA™ with a redesigned nose profile and a reamer housing blade profile that improves flow by area by over 40%.
