Hey Tom! Episode 4 – in this episode Tom is talking about how performance means different things to different people. For the driller, it means drilling more meters than his back-to-back. For the bit provider, it means getting more ROP than his competitors. ED-Project’s KPI is to minimise back reaming by effective stabilisation which counteracts the reactive torque from the large cutter PDC bit. In this particular section, the total back reaming time while POOH was 26 minutes.
