Estudio para el Incremento del Factor de recobro en Núcleos de las Arenas “T” y “U” del Campo Shushufindi con la Aplicación de Recuperación Mejorada Mediante la Inyección de Nanofluidos

Abstract

Mature fields in the Oriente Ecuatoriano are reaching depletion in the production of hydrocarbons after having produced for several decades, this due to the reduction in pressure that occurs in the reservoir. To increase the profitability of these fields and recover a greater amount of oil, it is essential to increase the recovery factor. With the Enhaced oil Recovery methods, an increase in the recovery factor can be achieved; one of the innovative and attractive advances is the use of nanoparticles to be injected into the reservoir to increase oil recovery. Within this investigation, it was determined that the Shushufindi field is the ideal candidate for the use of nanofluids because it is a colossal mature field.

This project consisted of the injection of nanoparticles formulated in the Escuela Politécnica Nacional with the help of Formation Damage System (FDS) equipment in the Petroamazonas laboratory in plugs of the “U” and “T” sandstones extracted from the crown core of the wells Shushufindi 74 and 79. The variation of the recovery factor was evaluated and the results were checked by mathematical simulation in Matlab software. Since there is an increase in the recovery of crude oil of 18.44% for the Shushufindi 74 well and 20.96% in the Shushufindi 79 well, the application of nanoparticles in the recovery of the hydrocarbon is a good option to be used and for its cost in inputs profitable and will become the future of the oil industry.
