N2  - Resumen del autor, extraído del trabajo. This paper presents a method for optimizing the itinerary of workover rigs, searching for the route of minimum total cost. The total cost of a route includes the rig expenses (transport, assembly and operation), which are functions of time and distances, plus the losses of revenue in wells waiting for the rig, which are also dependent of time. A reservoir simulator is used to evaluate the monetary influence of the well shutdown on the present value of the production curve. Finally, search algorithms are employed to determine the route of minimal cost. The Simulated Annealing algorithm was also successful in optimizing the distribution of a list of wells among different workover rigs. The rational approach presented here is recommended for management teams as a standard procedure to define the priority of wells scheduled for workover
