Estudio de factibilidad para la implementación de un nuevo sistema que permita recuperar sistemas electro sumergibles sin taladro

Abstract

The oil reservoirs deplete and lose their natural energy to produce fluids to surface, New artificial lift systems have become essential to maintain the oil production. Most of times, ESP systems are selected as the optimal artificial lift system. Alternative methods for the ESP deployment have grown in recent years. This paper presents a feasibility study where is evaluated the application of the new technology Zeitecs, which allows the recovery of ESP systems without the need of a workover rig. Then, is described the main components of Zeitecs, advantages, limitations, previous local and international implementations. Then, is presented a general description of the JP field considered for the evaluation of a possible application of Zeitecs, the condition of the wells, the failure rate of the ESP systems, the average ESP run life and a summary of the main causes of the last interventions carried out in the ESP wells and the main actions taken. Next, a workflow is presented describing the process for the selection of possible wells candidates for an application of Zeitecs. After that, is presented the analysis and evaluation of four generic wells as possible candidates for the application of Zeitecs technology, establishing the different scenarios and economic considerations. Finally, the economic results, conclusions and recommendations are presented. Finally, the causes that led to the success or failure of the fracturing works evaluated are clarified.
