(FR) GÉODIRECTION FONDÉE SUR UNE PRÉDICTION AUTOMATISÉE DE PERFORMANCES DE PUITS
Abstract
(EN)
Systems and methods for automated planning and/or control of a drilling operation are implemented to be based at least in part on automated prediction of well performance using an analytical well performance model. Substantially real-time determination of one or more drilling parameters and/or well trajectory parameters is based on measurements received from a drill tool together with the well performance model. The described techniques thus provide for automated, analytically determined well performance measures (e.g., well productivity and/or revenue) to a geosteering process. The well performance model accounts for variations of well trajectory both in inclination and in azimuth angle.

La présente invention concerne des systèmes et des procédés pour la planification et/ou la commande automatisées d'une opération de forage. Les systèmes et procédés sont mis en œuvre pour être fondés au moins en partie sur la prévision automatisée de performances de puits en utilisant un modèle analytique de performances de puits. La détermination sensiblement en temps réel d'un ou de plusieurs paramètres de forage et/ou paramètres de trajectoire de puits est fondée sur des mesures reçues à partir d'un outil de forage ainsi que sur le modèle de performances de puits. Les techniques décrites permettant ainsi des mesures automatisées, analytiquement déterminées de performances de puits (par exemple, productivité et/ou revenus de puits) pour un procédé de géodirection. Le modèle de performances de puits prend en compte des variations de trajectoire de puits à la fois en termes d'inclinaison et en termes d'angle d'azimut.
