Title (EN) INDUCTION LOGGING BOREHOLE CORRECTION FOR WATER-BASED MUD
(FR) CORRECTION DE PUITS DE FORAGE PAR DIAGRAPHIE DE CONDUCTIVITÉ POUR DE LA BOUE À BASE D'EAU
Abstract:
(EN) A method of borehole correction for water-based mud includes conveying an induction logging tool along a borehole through a formation, obtaining one or more formation measurements using the tool, obtaining a water-based mud conductivity, performing an oil- based mud inversion on the formation measurements to determine an inverted formation conductivity, calculating a corrected formation conductivity using the water-based mud conductivity and the inverted formation conductivity, and displaying a log based at least in part on the corrected formation conductivity.
(FR) L'invention concerne un procédé de correction de puits de forage, pour de la boue à base d'eau, qui comprend le transport d'un outil de diagraphie de conductivité le long d'un puits de forage dans une formation, l'obtention d'une ou de plusieurs mesures de la formation à l'aide de l'outil, l'obtention d'une conductivité de boue à base d'eau, l'exécution d'une inversion en boue à base d'huile sur les mesures de la formation pour déterminer une conductivité inversée de la formation, le calcul d'une conductivité corrigée de la formation à l'aide de la conductivité de la boue à base d'eau et de la conductivité inversée de la formation et l'affichage d'une diagraphie sur la base au moins en partie de la conductivité corrigée de la formation.
