The HPOGC hydraulic PDC cutter underreamer is used to enlarge boreholes beyond bit diameter. The retractable under reamer arms can be opened and closed multiple times while downhole, making it the best choice for selective section enlarging jobs.
This simple and efficient arm design increases longevity and facilitates simple field maintenance.
The optimum placement of mud ports on the tool ensures thorough cleaning of the PDCs for faster reaming with less pack-off risks.
Each HPOGC underreamer body can be fitted with any size of arms within its opening range. We can manufacture and deliver extra arms on short notice. Custom bodies can also be provided to accommodate for different hole diameters.
