Propuesta de un modelo de confiabilidad basado en el contexto operativo del Bloque 57 Libertador para el sistema de reinyección de agua en la Empresa Petroamazonas EP

Abstract

This research work has as purpose to determine the reliability of the water reinjection system in block 57 Liberator, Sucumbios Province, Pacayacu [Parish], which is based on a real analysis of the operational context, taking into account the intrinsic availability, associated with the reliability and maintainability of the elements that comprise it. The main objective of any company is predicting failure modes to prevent the consequences that this entails, since it requires learning of the previous history to make improvements in the future through o root cause analysis that would help eliminate its recurrence. The methodology used was the field research and historical records available since 2013, date in which it started to record failures in the “Maximum for Oil and Gas” maintenance and management software. It was also used observation techniques, revision of: data quality, operating daily reports, process diagrams, functional schematics and established methods such as analysis of goodness of-fit for the distribution Exponential probability and Weibull. The results of reliability for the 7 types of equipment involved in the water reinjection system were correlated based on failures by type of equipment throughout the available population to block 57 Liberator, this establishes the block diagram of reliability, with which it is possible to predict a value of probability of failure of an estimate for each system. Finally, it is possible to propose actions to prevent the reliability of the system from being lower than 50% in a period of 3000 hours of continuous operation, and the intrinsic availability of the systems from being lower than 99.9% thanks to the opportune maintenance intervention. It is recommended to implement the model proposed in this research for better results.
