Impact Geothermal Wireline Guide Rollers are used in deviated well bores and are installed on the bottom end of the tool string. With independent swiveling, the self-orienting roller body ensures the rollers are oriented at all times to the low side of the well bore. The tool string is lifted onto large, highly efficient rollers, reducing contact friction and enabling easier wellbore access. The running weight remains positive and steady, pick up weight is greatly reduced and the risk of wire breaks is lowered.
