CA 2698743

Methods and systems for drilling to a target location include a control system that receives an input comprising a planned drilling path to a target location and determines a projected location of a bottom hole assembly of a drilling system. The projected location of the bottom hole assembly is compared to the planned drilling path to determine a deviation amount. A modified drilling path is created to the target location as selected based on the amount of deviation from the planned drilling path, and drilling rig control signals that steer the bottom hole assembly of the drilling system to the target location along the modified drilling path are generated.

La présente invention concerne des procédés et systèmes pour forer à un emplacement cible comprenant un système de commande qui reçoit une entrée comprenant un chemin de forage planifié à un emplacement cible et détermine un emplacement projeté d'un ensemble de fond de trou d'un système de forage. L'emplacement projeté d'un ensemble de fond de trou est comparé au chemin de forage planifié pour déterminer une quantité d'écart. Un chemin de forage modifié est créé à l'emplacement cible tel que sélectionné en se basant sur la quantité d'écart par rapport au chemin de forage planifié, et des signaux de commande d'outil de forage qui dirigent l'ensemble en fond de trou du système de trou vers l'emplacement cible le long du chemin de forage modifié sont générés.
