A method for treating well tubulars and elements (e.g. tubing, casing, sucker rods, etc.) for corrosion, drag reduction, or the like wherein a mass of gelatin is passed downward through the tubular to deposit a protective layer onto the wall of the tubular and/or element. Preferably, the mass of gelatin contains a treating solution therein which forms part of the protective layer. Since such treating solutions can severely damage the production and/or injection formation, the mass is stopped before it completely travels through the tubular and circulation is reversed to return any remaining mass of gelatin and solution back up the tubular towards the surface.
