Title (EN) INVERSION-BASED CALIBRATION OF DOWNHOLE ELECTROMAGNETIC TOOLS
(FR) ÉTALONNAGE BASÉ SUR UNE INVERSION D'OUTILS ÉLECTROMAGNÉTIQUES EN FOND DE TROU
Abstract: front page image
(EN)An inversion based calibration method for downhole electromagnetic tools includes processing an inversion of a formation model using acquired electromagnetic measurement data to obtain formation parameters and calibration parameters for at least one measurement array.
(FR)La présente invention concerne un procédé d'étalonnage basé sur une inversion d'outils électromagnétiques en fond de trou comprenant la réalisation d'une inversion d'un modèle de formation en utilisant des données de mesures électromagnétiques acquises pour obtenir des paramètres de formation et des paramètres d'étalonnage d'au moins un groupement de mesures.
