Waveguide Analysis of Radiofrequency Transmission in Well Tubulars for Electromagnetic Heating of Heavy Oil

This paper presents the numerical modelling and simulation of a 2D vertical well tubular model excited by coaxial radiofrequency transmission line placed in its annular space for purpose downhole RF energy transmission. The study identifies mechanism losses due to coupling between steel tubing casing using resonance mode analysis. design left-handed artificial power is proposed minimize right-handed properties line. utilizes ideal lumped element method determine left-handedness over industrial heating radio-frequency band. developed simulated COMSOL multi-physics commercial software. effect position within on tangential magnetic field resulting along discussed. It observed that improves 60 m depths oil
