A Fully Coupled Numerical Model for Microwave Heating Enhanced Shale Gas Recovery

A numerical study of performance for tight gas and shale gas reservoir systems

Various analytical, semi-analytical, and empirical models have been proposed to characterize rate and pressure behavior as a function of time in tight gas and shale gas systems featuring horizontal wells with multiple hydraulic fractures. Despite a few analytical models, as well as a small number of published numerical studies, there is currently little consensus regarding the large-scale flow ...

Coupled Thermal-Electromagnetic Model for Microwave Heating of Temperature-Dependent Dielectric Media

Microwave heating processes involve electromagnetic and thermal effects coupled together through the local temperature dependence of the material dielectric properties. This paper presents a one-dimensional model for the coupled electromagnetic-thermal process and demonstrates its solutions for typical problems. The local temperature dependence of the lossy dielectric medium is taken into accou...

Simulation Study of Enhanced Condensate Recovery in a Gas-Condensate Reservoir

Multiscale model reduction for shale gas transport in fractured media

In this paper, we develop a multiscale model reduction technique that describes shale gas transport in fractured media. Due to the pore-scale heterogeneities and processes, we use upscaled models to describe the matrix. We follow our previous work [1], where we derived an upscaled model in the form of generalized nonlinear diffusion model to describe the effects of kerogen. To model the interac...

Review of Numerical Simulation of Microwave Heating Process

Since the great experiments were carried out by Dr. Percy Spencer in 1946, microwave heating has been used widely in food industry, medicine, chemical engineering and so on [1][2][3][4][5], for processing many materials ranging from foodstuffs [1][6][7][8] to tobaccos [9][10][11], from wood [12][13][14] to ceramics [15][16][17][18], and from biological objects [19][20] to chemical reactions [21...
