Abstract
A downhole system includes a downhole string insertable within a subterranean wellbore and a roller assembly coupled with the string. The roller assembly includes rollers mounted on lateral sides of the downhole string for reducing the resistance of deploying the string within the wellbore. The string is rotatable about its axis with respect to the roller assembly; bearing surfaces, or low torque surfaces, are included in the roller assembly to further reduce rotational friction so the string precisely positions itself to a designated orientation.
