Optimización de la producción del campo sacha utilizando el principio estadístico de Pareto

Abstract

CONDITION FOR PUBLICATION OF PROJECT. The Sacha Field, located in Orellana province, is one of Ecuador’s main oil producers but currently faces challenges typical of mature reservoirs, such as high water cut, natural decline, and aging infrastructure. The objective of this project is to apply the Pareto statistical principle to identify the most representative wells and prioritize interventions that maximize hydrocarbon recovery, under the hypothesis that a reduced number of wells accounts for most of the production, thus justifying the need to focus technical efforts. Historical production data were collected and analyzed, wells were classified by cumulative output, and Pareto charts were developed in Microsoft Excel to determine the most productive wells. Results showed that approximately 40% of the wells concentrate around 80% of total production, with the replacement of ESP systems identified as the most impactful intervention. It is concluded that the application of the Pareto principle allows prioritizing investments in high-potential wells, optimizing resources, and ensuring the productive sustainability of the field.
