Simulación dinámica y análisis de las variables de operación en las líneas de producción de REPSOL NPF, Bloque 16

Abstract

The present work of Dynamic Simulation and Analysis of operating variables in the production lines of Repsol NPF, Block 16 was carried out in the oil company Repsol-Ecuador in charge of the operation of Block 16, which is located in the province of Orellana near the Yasuni National Park and the Waorani Ethnic Reserve, with the objective of analyzing the hydraulic behavior of the production and transport lines under variations in the operating conditions in the simulation models developed. For the development of the project, information and operation data reported in the field were collected, as well as PVT analysis of the producing sands of each field and of the hydrocarbon fluid currents that enter and leave the North Production Facilities. Normal operating conditions were defined for each simulated production line based on operating pressure, temperature and flow rate. Hysys and PVTsim software were used as tools to characterize the fluids transported in each line and to know their composition, as well as OLGA software, which facilitated the understanding of the hydraulic behavior of the lines in an almost real environment; once the simulation models were developed in OLGA, production scenarios were analyzed such as: sending cleaning tools in pipelines, production stops and starts and use of pumps in intermediate pumping stations in order to predict the probable production losses when operating conditions varied. The results obtained for pressure, temperature and flow through the simulation models showed an error percentage of less than 10% between the results obtained in the simulation and the real operating conditions, indicating the reliability of the models developed. Based on the results obtained, it was concluded that using OLGA software it is possible to simulate and analyze the hydraulic behavior of Repsol NPF's production and transportation lines based on the main operating variables such as pressure, temperature and flow rate. Therefore, it is recommended that the company continue developing projects with simulation models using OLGA software to ensure flow in pipelines and analyze future scenarios in order to avoid production losses in the other production lines in Block 16.
