Técnicas conjuntas para recuperação avançada de óleo utilizando irradiação eletromagnética e unidades de fluxo hidráulico

Abstract

This work proposes a model to investigate the use of a cylindrical antenna as a thermal recovery method by electromagnetic irradiation of high viscosity oil, associated with the hydraulic flow unit (HFU) technique to determine the best producing zones in the reservoir. The antenna has a simple geometry, of the adapted dipole type, the distribution of energy and temperature produced by the electric field is carefully calculated for analysis of the antenna as an electromagnetic heater. The production will be analyzed using thermo- fluid dynamics simulations on a field scale using a heterogeneous synthetic model built from data sets from the SE-AL oil field for heavy crude oil, whose viscosity model corresponds to that found in Canadian tar sands. The parametric study evaluates the best operating frequency, well configuration, antenna distance to the producing well, and economic analysis for accumulated net production, with electrical energy, using numerical simulations, through adaptation in the STARS® (CMG) software.
