Audited Supplier API Pony Rod and Pup Joint Down-hole Tools
Pony Rod
Pony rods are sucker rods shorter than 25 ft, with various length. They are mostly placed adjacent to the polished rod at the top of rod string, on top of the downhole pump for handling purposes, and on top of the polished rod with appropriate couplings to prevent the string from falling downhole if the polished-rod clamp slips.
Normally, old pony rods should not be used in the load-carrying part of a new rod strings. Thus, when placing the rod string with new suckers, new pony rods should be used.
