Abstract: A cable coater system for a downhole tool includes a cable coater. The cable coater may include a housing and one or more rollers that are coupled to the housing, wherein the one or more rollers are configured to rest on the downhole cable while guiding the cable through openings in the cable coater during wireline operations. The cable coater may remain on cable during all spooling (on and off) activities for the duration of operations and activated to coat the cable upon the final pull out of hole and prior to storage of the cable. The spooling in and out of the cable may further be automatically controlled by providing a positional indicator of the cable coater and thus where the cable is in three-dimensional space relative the spool.
