    Copyright 2017, Society of Petroleum Engineers. This article presents the results of experimental modeling of heat and mass transfer processes in oil-containing media caused by natural thermal convection. In this research we designed the laboratory setup and obtained experimental data for single- and two-component liquids medium with different permeability. It was shown that the dynamic of the media heating and the value of the oil recovery coefficient obtained experimentally and numerically by using the CMG STARS program coincides well. It was found that the processes of heat and mass transfer occur most intensively when the temperature of the medium near the heater reaches the value equals to the boiling point of water. The heating of the zone around the heater occurs faster, if a medium has a lower permeability. The oil recovery coefficient reached 55% with an initial water saturation coefficient of 0.52 and other conditions which corresponded to Ashalchinskoye oil field, Republic of Tatarstan, Russian Federation. This result is in a good agreement with the numerical result calculated by the CMG STARS program

    © Published under licence by IOP Publishing Ltd.The method of natural thermal convection with heat agent recirculation (NTC HAR) in oil reservoirs is described. The analysis of the effectiveness of this method for oil reservoir heating with the values of water saturation from 0 to 0.5 units is conducted. As the test element Ashalchinskoye oil field is taken. CMG STARS software was used for calculations. Dynamics of cumulative production, recovery factor and specific energy consumption per 1 m3 of crude oil produced in the application of the heat exchanger with heat agent in cases of different initial water saturation are defined and presented as graphs
