[54] SYSTEM AND METHOD FOR POSITIONING A BOTTOM HOLE ASSEMBLY IN A HORIZONTAL WELL
[57] Abstract: A system of couplings and method of use of the couplings to locate a downhole tool connected to coiled tubing, such as a bottom hole assembly, within a selected segment of a casing string. The selected segment of casing may be a ported collar or ported housing that permits the treatment and/or stimulation of the adjacent well formation. The system of couplings may be two, three, or four couplings that are spaced apart at predetermined lengths. The predetermined lengths may be shorter than typical lengths of casing segments. The distance between the first and second coupling may be substantially identical to the distance between the third and fourth coupling. The use of distances between the couplings that are shorter than the length of conventional casing segments may provide surface indicators as to the location of the bottom hole assembly with a higher confidence than relying on a traditional tally sheet.
