Zusammenfassung:A centralizer with low friction buttons comprising a plurality of collars including a first collar and a second collar; a plurality of bow springs, each bow spring having a first end and a second end; and a plurality of low friction buttons. The plurality of bow springs extend between the first and second collar such that the first and second end of each bow spring is connected to the first and second collar respectively; the plurality of low friction buttons are mounted on the bow springs such that they act as the only point of contact between the centralizer and borehole during movement of the pipe casing while getting it to the total depth during drilling operation, said buttons being of the type whose coefficient of friction is lesser than the rest of the body of the centralizer.
