Workover of wells is one of the most important processes in the oil industry because it recovers or increases the hydrocarbon production of an oil well that, because of mechanical conditions or the reservoir, is producing volumes less than their optimal value. The workover process of the national oil company Petroamazonas EP in an oilfield in the Ecuadorian Oriente Basin was analyzed in order to define an improvement proposal using tools commonly used in Industrial Engineering. Considering the point of view of the clients of the process, it was determined that the parameter subject to improvement is the time. In order to determine the operations to be optimized, the available information of the workovers made in the oilfield, from January 2015 to January 2017, was collected and analyzed. Using Pareto analysis, two operations to be improved were determined: Initialization and Completion. For these operations, control charts were performed in order to determine values outside the expected ranges of time. At the farthest points a cause-and-effect analysis was applied to determine the main cause of the failure. Considering the results of the analysis, a proposal was developed to improve the workover process.
