Abstract
Un procédé pour guider une trajectoire de forage dun second puits (12, 80) situé à proximité immédiate dun premier puits (10, 102). Ledit procédé consiste à connecter électriquement une source de courant électrique variant dans le temps (26, 70) à une extrémité proximale et à une extrémité distale (106) dun tubage conducteur (68) ou dune colonne perdue; à appliquer le courant électrique variant dans le temps directement au tubage conducteur ou à la colonne perdue du premier puits de manière que le courant (62, 114) circule dans une direction commune essentiellement sur toute la longueur du tubage ou de la colonne perdue, le courant électrique étant injecté à une extrémité du tubage ou de la colonne perdue et circulant vers une extrémité opposée du tubage ou de la colonne perdue; à forer le second puits (12) le long dune trajectoire de forage (86); à partir du second puits, à détecter (44, 46, 48, 52, 88) un champ électromagnétique généré par le courant électrique variant dans le temps dans le tubage ou la colonne perdue du premier puits, alors que le courant électrique variant dans le temps est appliqué au tubage ou à la colonne perdue du premier puits; à déterminer une distance et une direction entre les premier et second puits; et à guider la trajectoire de forage du second puits en utilisant la distance et la direction déterminées pour maintenir une séparation entre les premier et second puits.
