ABSTRACT:
A method to create a drilling performance assessment ratio. The ratio includes the steps of establishing a technical minimum time limit standard for each of multiple sequential steps required for a drilling operation. Actual time performance for each of the multiple steps is measured for an actual drilling operation. The actual performances are compared to the technical time limit standards in order to produce a drilling performance ratio.
