CA 2574919

A method is disclosed for determining spatial distribution of resistivity of Earth formations surrounding a wellbore having a conductive pipe therein. The method includes measuring resistivity of the Earth formations using measurements of current leakage along the pipe at selected axial positions. Electromagnetic properties of the Earth formations are measured from within the pipe. The measurements of electromagnetic properties correspond to a larger axial distance and to a greater lateral distance than the measurements of resistivity from current leakage. The current leakage and electromagnetic measurements are jointly inverted to obtain a model of the spatial distribution.

Un procédé permet de déterminer la répartition spatiale de la résistivité des formations terrestres autour d'un puits comportant un tuyau conducteur. Ce procédé consiste à mesurer la résistivité des formations terrestres sur la base des mesures de fuite de courant le long de tuyau en des points axiaux précis. Les propriétés électromagnétiques des formations terrestres sont mesurées à l'intérieur du tuyau. Les mesures des propriétés électromagnétiques correspondent à une distance axiale plus élevée et à une distance latérale plus étendue par rapport aux mesures de résistivité des fuites de courant. Les fuites de courant et les mesures électromagnétiques sont conjointement inversées pour obtenir un modèle de répartition spatiale.
