Desarrollo del mapa de presiones para las arenas u y t del campo sacha mediante el análisis de pruebas de presión: construcción del mapa de presiones para la arena u del campo sacha con el uso del análisis de pruebas de presión.

Abstract

The reinterpretation of the pressure increase tests implemented throughout the productive life of the U sandstone from the Sacha field was carried out, and from the results of the reinterpretation a relationship was obtained between the behavior of pressure as a function of production and the reservoir pressure was estimated as of December 2023. From an initial base of 432 pressure tests of the Napo “U” formation, 151 pressure tests were discarded and selected based on the information available about them. Using another filter, due to the quality of the information provided, a total of 68 pressure tests were analyzed through the Saphir NL software. A pressure estimate was made for each interpreted well, which was estimated based on the pressure and production relationship obtained and based on the years elapsed since the date of the increase test. An isobaric map was generated based on the 68 pressures obtained and from which an average pressure representative of the Napo “U” formation of the Sacha field of 1380.94 psi was estimated.
