Abstract

La présente invention concerne des procédés permettant d'obtenir de multiples mesures de télémétrie magnétique indépendantes lors d'une mise en uvre de jumelage de puits. Les procédés peuvent consister à utiliser un instrument de télémétrie magnétique présentant des premier et second solénoïdes espacés axialement. Les procédés peuvent en variante et/ou en outre consister à utiliser un instrument de télémétrie magnétique comportant un électroaimant en vue d'étalonner un tubage magnétisé. Les procédés peuvent encore en outre consister à mesurer la composante axiale d'un champ magnétique à l'intérieur d'une colonne de tubage magnétisée à la suite du déploiement de la colonne dans un puits cible.
