THE CENTRALIZER (100) INCLUDES A ONE PIECE INTEGRAL HOLLOW ELONGATED STRUCTURE (102) SELECTED FROM A GROUP OF A METAL TUBE AND A METAL SHEET ROLLED AND LONGITUDINALLY CONNECTED TO DEFINE A METAL TUBE. THE HOLLOW ELONGATED STRUCTURE (102) INCLUDES A FIRST END PORTION (110) AND A SECOND END PORTION (112) LONGITUDINALLY SPACED APART FROM EACH OTHER. THE HOLLOW ELONGATED STRUCTURE (102) ALSO INCLUDES AN INTERMEDIATE BOWED PORTION (120) INTEGRALLY EXTENDING BETWEEN THE FIRST END PORTION (110) AND THE SECOND END PORTION (112). THE INTERMEDIATE BOWED PORTION (120) INCLUDES A PLURALITY OF LONGITUDINAL SLITS (122) AND A PLURALITY OF STAVES (124) SPACED APART BY THE PLURALITY OF SLITS (122). THE PLURALITY OF STAVES (124) IS LONGITUDINALLY BENT TO PROTRUDE OUTWARDLY. THE CENTRALIZER (100) IS ADOPTED TO DEFORM WHEN MOUNTED ON THE WELL CASING (10) AND FORCED INTO WELL BORE (20) HAVING INNER OBSTRUCTION OF LESS DIAMETER THAN THE MAJORITY PORTION OF THE WELLBORE INNER DIAMETER.
