Title (EN) METHOD OF PREDICTING THE RESPONSE OF AN INDUCTION LOGGING TOOL
(FR) PROCÉDÉ DE PRÉDICTION DE LA RÉPONSE D'UN OUTIL DE DIAGRAPHIE PAR INDUCTION
Abstract: front page image
(EN)There is provided a method of predicting the response of an induction logging tool along an arbitrary trajectory in a three-dimensional earth model, wherein the method comprises a confinement of the electromagnetic field computations to a limited domain of the geology surrounding the induction logging tool. The magnetic field at a receiver coil is considered as a superposition of a primary background constituent and a secondary constituent. A single spherical scatterer aproximation is used for the second constituent.
(FR)L'invention porte sur un procédé de prédiction de la réponse d'un outil de diagraphie par induction le long d'une trajectoire arbitraire dans un modèle terrestre tridimensionnel, le procédé comprenant un confinement des calculs de champ électromagnétique sur un domaine limité de la géologie entourant l'outil de diagraphie par induction. Le champ magnétique au niveau d'une bobine réceptrice est considéré comme une superposition d'une composante de fond primaire et d'une composante secondaire. Une seule approximation de diffuseur sphérique est utilisée pour la seconde composante.
