I’ve got an email asking me about how to figure out the total bit revolution (RPM) at down hole when the mud motor is used in the drill string and rotating at surface is also conducted.
There are two components contributing in the total revolution of downhole drilling bit using mud motor.

Minagesh, West Kuwait
Upon the completion of contract & de-hiring, a drilling rig was being moved from KOC field to the contractor Yard. The rig was being towed by the rig move sub contractor & was steered by the night duty rig mechanic.
The rig pick-up vehicle driven by roustabout along with the Toolpusher was trying to overtake the rig. The pick-up drove outside the normal road though the elevated loose sand to overtake the rig. The incident happened at a curved portion of the road where the rig tires were at the extreme end of the road on the pavement.
