On Theory of Thermal Recovery of High-Viscosity Oil

Abstract

A theoretical model of the development of a high-viscosity oil reservoir using the technology of paired horizontal wells is presented. The problem was solved numerically assuming that the two-well system is replaced by one hypothetical well through which simultaneous heating of the reservoir and oil recovery are performed. The heat consumption for heating the reservoir, the change in flow rate, and the mass of extracted oil for a certain period of time were analyzed for different values of the heating temperature, pressure difference, and induction period of the well. The obtained solutions can be used to determine heating conditions optimal in energy consumption.
