High Viscosity Oil

In the paper the heat of high-viscosity oil reservoir using two physical fields: RF electromagnetic fields and acoustic. It is the simultaneous production of oil. The formula is derived for the volume of heat sources, resulting in the formation therein during propagation of acoustic waves, which is suitable for the calculations in any zone of the formation. A mathematical model based on the heat equation in cylindrical coordinates. The equation depends only on the radial coordinate. Problem is solved by the finite difference method for the implicit scheme. It is shown that neglecting the absorption of acoustic waves in a thermally distorts the real picture of the temperature field in the formation.

We investigate the possibility of increasing the efficiency of extraction of high-viscosity oil combined effect of radio-frequency (RF) electromagnetic (EM) and acoustic fields on the formation and miscible displacement oil solvent. A mathematical model of two-stage impact on the oil reservoir. At the 1st stage, the heating of the formation RF electromagnetic and acoustic field. At the 2nd stage the RF heating of the formation with simultaneous injection of low-viscosity solvent.

Oil Filtration

A theoretical and numerical study of developing a reservoir with high-viscosity oil using the technology of pair horizontal wells is presented. In a two-dimensional formulation, numerical solutions to the problem of the possibility of extracting high-viscosity oil from a formation with the use of thermal action were obtained. The proposed method is aimed at increasing the efficiency of developing an oil reservoir with high viscosity oil by ensuring a uniform warming up of the developing zone of the field. The adopted model allows to trace a detailed two-dimensional picture of oil filtration in the reservoir and to investigate the main regularities of this process.
