“…For petroleum-based applications, the use of microwaves has been primarily observed in enhanced oil recovery (EOR) techniques. Several studies have been performed to determine the efficiency of electromagnetic heating as a support method for EOR (Kislitsyn and Nigmatulin, 1990;Kovaleva et al, 2004;Sayakhov et al, 2002;Sysoev and Kislitsyn, 2011). In the case of hydrate reservoirs, the decomposition of methane hydrate into gas and water is an endothermic reaction.…”

Purpose This paper aims to present the implementation of a multi-layer radiation propagation model in simulations of multi-phase flow and heat transfer, for a dissociating methane hydrate reservoir subjected to microwave heating. Design/methodology/approach To model the induced heterogeneity due to dissociation of hydrates in the reservoir, a multiple homogeneous layer approach, used in food processes modelling, is suggested. The multi-layer model is incorporated in an in-house, multi-phase, multi-component hydrate dissociation simulator based on the finite volume method. The modified simulator is validated with standard experimental results in the literature and subsequently applied to a hydrate reservoir to study the effect of water content and sand dielectric nature on radiation propagation and hydrate dissociation. Findings The comparison of the multi-layer model with experimental results show a maximum difference in temperature estimation to be less than 2.5 K. For reservoir scale simulations, three homogeneous layers are observed to be sufficient to model the induced heterogeneity. There is a significant contribution of dielectric properties of sediments and water content of the reservoir in microwave radiation attenuation and overall hydrate dissociation. A high saturation reservoir may not always provide high gas recovery by dissociation of hydrates in the case of microwave heating. Originality/value The multi-layer approach to model microwave radiation propagation is introduced and tested for the first time in dissociating hydrate reservoirs. The multi-layer model provides better control over reservoir heterogeneity and interface conditions compared to existing homogeneous models.

“…The damping of the electromagnetic wave is caused by volume losses in the dielectric corks and surface losses in the metal walls of a cylindrical waveguide due to the imperfection of the conductivity of its surface The process of heating and melting asphalt-paraffin deposits under the influence of high-frequency electromagnetic radiation was studied on the basis of heat conduction equations with a given external heat source, which moves in the pipe in the longitudinal direction so that the minimum longitudinal distance from it to the surface phase transition was permanent. Considered axisymmetric problem, equation of heat conduction is written in a General form without explicit allocation of the phase [2,3]:…”
