Abstract

A STRING OF WELL TUBULAR, SUCH AS A WELL CASING OR A DRILL STRING, IS PRIOR TO INSTALLATION OF THE STRING IN BOREHOLE MAGNETIZED ALONG AT LEAST PART OF THE LENGTH THEREOF BY CREATING A MAGNETIC FIELD HAVING FLUX LINES WHICH PASS IN A SUBSTANTIALLY LONGITUDINAL DIRECTION THROUGH AN ELONGATE SECTION OF THE STRING, THEREBY MAGNETIZING SAID SECTION SUCH THAT IT HAS OPPOSED MAGNETIC POLES HAVING A POLESTRENGTH OF MORE THAN 3000 UWB. (FIG. 1)
