La tecnología de inyección de nanofluidos (nanopartículas dispersas en un fluido de acarreo) ha sido estudiada en reducciones de tensión interfacial, aumentos de viscosidad de fase desplazante y en alteraciones de humectabilidad en la roca; factores que impactan directamente en el número de capilar, favoreciendo aumentos en la recuperación del petróleo.

Despite all the controversies, the consumption of fossil fuels is the main source of energy worldwide, with oil supplying 36% of the global energy demand. Thus, the industry's interest in obtaining greater amounts of crude oil from the reservoirs is maintained through processes of enhanced oil recovery (EOR), with special focus on unconventional ...

Enhanced oil recovery (EOR) processes simulation is governed by mass conservation laws. In such laws, ow, accumulation, sources and sinks phenomena in porous media are described. Multiple proposals for framework and simulation elaboration have been de_ned. However, they lack concepts and processes tracing and event representation for physical phenomena.

The processes of improved thermal recovery by cyclic steam injection have been used successfully in heavy and extra-heavy crude oil reservoirs as a strategy for recovering remaining reserves. The increase in oil recovery is caused by the reduction in viscosity of crude oil, which leads to an increase in mobility and a decrease in the residual ...
