Title
(EN) DETERMINING A LANDING ZONE IN A SUBTERRANEAN FORMATION
(FR) DÉTERMINATION D'UNE ZONE D'ACCROCHAGE DANS UNE FORMATION SOUTERRAINE
Abstract
(EN)
Techniques for generating a geological model include identifying a plurality of well data for each of a plurality of wells drilled into a reservoir basin from a terranean surface. The reservoir basin includes a plurality of landing zones formed under the terranean surface, each of the landing zone including a discrete geological layer. The techniques further include comparing the plurality of well data for each well with a reservoir basin database that associates the well data with one of the plurality of landing zones; correlating each of the plurality of wells with a particular landing zone of the plurality of landing zones based on the comparison; and generating a geological model of the reservoir basin based on the correlated wells.

La présente invention concerne des techniques de génération d'un modèle géologique consistant à identifier une pluralité de données de puits pour chaque puits d'une pluralité de puits forés dans un bassin de réservoir à partir d'une surface terrestre. Le bassin de réservoir comprend une pluralité de zones d'accrochage formées sous la surface terrestre, chacune des zones d'accrochage comprenant une couche géologique distincte. Les techniques consistent en outre à comparer la pluralité de données de puits pour chaque puits avec une base de données du bassin de réservoir qui associe les données de puits à l'une des zones de la pluralité de zones d'accrochage ; à corréler chaque puits de la pluralité de puits avec une zone d'accrochage particulière de la pluralité de zones d'accrochage sur la base de la comparaison ; et à générer un modèle géologique du bassin de réservoir sur la base des puits corrélés.
