Title (EN) OPTIMIZED GEOSTEERING USING REAL-TIME GEOLOGICAL MODELS
(FR) GÉODIRECTION OPTIMISÉE UTILISANT DES MODÈLES GÉOLOGIQUES EN TEMPS RÉEL
Abstract:
(EN) The present invention relates to a method and a system for optimized geosteering using real-time models that are updated LWD measurements containing data such as, for example, layer boundaries and formation properties, wherein the measurements are obtained by replacing TVD coordinates and MD coordinates for parameter entries in a parameter matrix, which can be updated, with TVD coordinates and MD coordinates for an actual well trajectory.
(FR) La présente invention concerne un procédé et un système de géodirection optimisée à l'aide de modèles en temps réel qui sont des mesures LWD mises à jour contenant des données telles que, par exemple, des limites de couches et des propriétés de formation, les mesures étant obtenues en remplaçant des coordonnées TVD et des coordonnées MD pour des entrées de paramètres dans une matrice de paramètres, qui peuvent être actualisées, par des coordonnées TVD et des coordonnées MD pour une trajectoire réelle du puits.
