Modelo de confiabilidad para sistemas de levantamiento artificial con bombas eléctrico sumergibles del Campo Shushufindi Bloque 57.

Abstract

The reliability model for artificial lifted systems with electric submersible pumps in the Shushufindi oil field – block 57 in Sucumbios province has been developed with the aim of reducing production losses caused mainly by equipment failure of electric submersible pump. The development of the model is based on the guidelines of the ISO 14224 standard, and the analysis of the operational context of each system. This scheme allows reducing the losses for failures in the electric pumps and their associated subsystems, increasing the lifetime of the equipment and components. The determination of the levels of the hierarchy established in the ISO 14224 standard in production processes can identify what are the failure types that affect the components, which once they fail, they generate the largest amount of lost production. The classification of production losses associated with the failure types allow to prioritize decisions and make a detailed analysis of the factors affecting the reliability of systems, identifying sensitive or susceptible to failure as a function of the operational context components. This analysis has identified what are the areas of production in which the electric submersible pumping systems have shorter useful life; it allows taking preventive action, in the design phase, and operation in order to increase the lifetime of useful systems for artificial lifted electric submersible pumps. Therefore, it is recommended to implement the model of reliability based on the stipulations of the ISO 14224 standard.
