CASING STAND-OFF BAND FOR USE WITH RUNNING AND CEMENTING OF CASING IN WELLBORES Abstract - Stand-off band of this invention is particularly useful when mounted on casing which must be run into deviated wellbores to assure that the casing does not stick prior to reaching a desired depth and permits the casing to be reciprocated up and down, or rotated, during the cementing operation, in order to obtain more effective cementing of the casing. The design and construction of this invention with its spiralled flutes cause the stand-off band to rotate relative to the wellbore and the casing and thus distribute the wear over the entire circumference of the stand-off band and during cementing the spiralled flutes guide the cement in a spiralled fashion for more effective displacement of the drilling mud from the annulus.
