1. A method of evaluating drilling performance in a wellbore, which comprises:
- monitoring an actual toolface orientation of a downhole steerable motor by monitoring a drilling operation parameter indicative of a difference between the actual toolface orientation and a toolface advisory;
recording the difference between the actual toolface orientation and the toolface advisory;
scoring the difference between the actual toolface orientation and a toolface advisory by assigning a value to the difference that represents drilling performance and varies depending on the difference; and
providing the value to an evaluator.

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.

15. A drilling-accuracy scoring apparatus for evaluating performance in drilling a wellbore, the apparatus comprising:
-
a sensor configured to detect a drilling operation parameter indicative of a difference between an actual toolface orientation of a downhole steerable motor and a toolface advisory; and a controller configured to calculate and score a difference between the actual toolface orientation and the toolface advisory by assigning a value to the difference that varies depending on the size of the difference and is representative of drilling accuracy; a display adapted to provide at least the calculated score to an evaluator. - View Dependent Claims (16, 17, 18, 19, 20)
