Abstract
An example robotic method for disassembling and removing a well string (e.g., a string of sucker rods or tubing within a wellbore) involves a computer controlled track and trolley system. Movement of multiple trolleys, carriages, shuttles, articulated arms and other hardware is orchestrated in a manner that minimizes cycle time and thus reduces the overall time for removing the entire well string. In some examples, upper and lower robots travel along and share a first set of tracks while an upper trolley mechanism and a main trolley travel along and share a second set of tracks. In some examples, the two sets of tracks are mounted vertically to a mast, wherein the mast is part of a workover vehicle.
