Title (EN) METHOD AND APPARATUS FOR ENHANCING FORMATION RESISTIVITY IMAGES OBTAINED WITH DOWNHOLE GALVANIC TOOLS
(FR) PROCEDE ET DISPOSITIF PERMETTANT D'AMELIORER LA QUALITE D'IMAGES DE LA RESISTIVITE DE FORMATIONS OBTENUES A L'AIDE D'OUTILS GALVANIQUES DE FOND DE TROU
Abstract: front page image
(EN)The average current at a plurality of measure electrodes of a resistivity imaging tool is determined and subtracted from the individual measure currents to give a resistivity image with improved dynamic range.
(FR)Dans la présente invention, le courant moyen au niveau d'une pluralité d'électrodes de mesure d'un outil d'imagerie de la résistivité est déterminé et soustrait de courants mesurés individuellement, afin de fournir une image de la résistivité avec une meilleure plage dynamique.
