Mud Pumps and associated equipment comprise the single largest investment on the modern drilling rig. Constant monitoring of the entire mud system is crucial not only to the protection of expensive equipment, but to the efficiency of the entire drilling operation.

Pump trouble, pipe trouble, trouble downhole - they all show up initially as a change in pump pressure. But that's not the whole story. Before any corrective action is taken, the driller must assure himself that the pump speed has not changed. NOV M/D Totco has simplified this process for the driller with its Tachometer Systems.

Rotary table RPM and Mud Pump SPM are two primary drilling parameters that must be closely monitored in order to achieve the maximum ROP and drilling efficiencies required in today's competitive drilling market. Tachometer systems provided by NOV M/D Totco enable drillers to monitor not only drilling operations but also equipment performance in support of preventive maintenance programs.
