Abstract:
Method, system, and apparatus for evaluating drilling accuracy performance in drilling a wellbore that can include: (1) monitoring an actual toolface orientation of a tool, e.g., a downhole steerable motor, by monitoring a drilling operation parameter indicative of a difference between the actual toolface orientation and a toolface advisory; (2) recording the difference between the actual toolface orientation and the toolface advisory; and (3) scoring the difference between the actual toolface orientation and the toolface advisory.
