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 (230); (2) recording the difference between the actual toolface orientation and the toolface advisory (240); and (3) scoring the difference between the actual toolface orientation and the toolface advisory (250).

L'invention porte sur un procédé, sur un système et sur un appareil d'évaluation de l'efficacité de précision de forage, dans le forage d'un puits de forage, qui peut comprendre : (1) la surveillance d'une orientation réelle de la face de coupe, par exemple un moteur orientable de fond de trou, par la surveillance d'un paramètre de fonctionnement de forage indiquant une différence entre l'orientation réelle de la face de coupe et une information de la face de coupe (230); (2)l'enregistrement de la différence entre l'orientation de la face de coupe réelle et l'information de la face de coupe (240), et (3) le pointage de la différence entre l'orientation réelle de la face de coupe et l'information de la face de coupe (250).
