Title
(EN) PIPE THICKNESS INVERSION USING A FAST FORWARD MODEL
(FR) INVERSION D'ÉPAISSEUR DE TUYAU EN UTILISANT UN MODÈLE D'AVANCE RAPIDE
Abstract
(EN)
A method and a system for estimating a pipe property for a plurality of nested pipes. The method may comprise determining the pipe property from the plurality of measurements, wherein the pipe property identifies a feature in the wellbore, forming a pre-computed table of responses for the at least one channel comprising a plurality of points that sample the pipe property, and performing a model-based inversion to estimate the pipe property using the plurality of measurements, the nominal properties of the pipes, and a fast forward model based on the pre-computed table of responses. A system may comprise an electromagnetic logging tool and an information handling system. The electromagnetic logging tool may comprise a transmitter, wherein the transmitter is a first coil and is operable to transmit an electromagnetic field, and a receiver, wherein the receiver and is operable to measure the electromagnetic field.

L'invention concerne un procédé et un système pour estimer une propriété de tuyau pour une pluralité de tuyaux emboîtés. Le procédé peut comprendre la détermination de la propriété de tuyau à partir de la pluralité de mesures, la propriété de tuyau identifiant une caractéristique dans le puits de forage, la formation d'une table pré-calculée de réponses pour le ou les canaux qui comprennent une pluralité de points qui échantillonnent la propriété de tuyau, et la réalisation d'une inversion à base de modèle pour estimer la propriété de tuyau en utilisant la pluralité de mesures, les propriétés nominales des tuyaux, et un modèle d'avance rapide sur la base de la table pré-calculée de réponses. Un système peut comprendre un outil de diagraphie électromagnétique et un système de traitement d'informations. L'outil de diagraphie électromagnétique peut comprendre un transmetteur, le transmetteur étant une première bobine et utilisable pour transmettre un champ électromagnétique, et un récepteur, le récepteur étant utilisable pour mesurer le champ électromagnétique.
