Products Details
-
The formation is cut by shearing instead of crushing which is much more predictable and reliable.
-
No moving parts mean there are no bearing or seals that could wear out during the drilling process.
-
Most wear is to the PDC cutters leaving the body mostly unharmed after drilling. Hence once all the cutters are worn, the drill bit can be repaired by Rockpecker, ensuring all quality parameters are met.
-
Unlike roller cone bits, the cutters are mechanically and chemically bonded to the bit body eliminating the issue of losing cones/cutters whilst drilling.
-
Gauge protection ensures outer-diameter of the bore is maintained.
-
Strategically placed Nozzle/Holes ensure cuttings are flushed out quickly.
-
Significantly higher junk flow area allows for more volume of cuttings to flow through hence the ROP can be increased substantially.
