Abstract[English]
Methods for modeling downhole formations include drilling, with a drill string, a drilling interval of a borehole through the downhole formation. The methods include obtaining measurement data for at least one measurement interval along the borehole, generating an initial composite model for a predefined region associated with the at least one measurement interval, calculating a best-fit model for the initial composite model based on the measurement data, performing a geometric partitioning and a property-driven partitioning of the initial composite model to generate a final composite model, and calculating a best-fit model for the final composite model based on the measurement data.[French]
Procédés de modélisation de formations de fond de trou comprenant le forage, avec un train de tiges, d'un intervalle de forage d'un trou de forage à travers la formation de fond de trou. Les procédés comprennent l'obtention de données de mesure pour au moins un intervalle de mesure le long du trou de forage, la génération d'un modèle composite initial pour une région prédéfinie associée à l'au moins un intervalle de mesure, le calcul d'un modèle de meilleur ajustement pour le modèle composite initial sur la base des données de mesure, la réalisation d'un partitionnement géométrique et d'un partitionnement entraîné par propriété du modèle composite initial pour générer un modèle composite final, et le calcul d'un modèle de meilleur ajustement pour le modèle composite final sur la base des données de mesure.
