What is it about?
By considering actual reservoirs as double-porosity thermoelastic media where fractures are embedded into an isotropic porous host, we extend the Lord-Shulman thermo-poroelasticity theory to the case of double porosity. Comparisons with laboratory measurements and well-log data from ultra-deep fractured carbonates at high temperatures illustrate the temperature dependence of dispersion and attenuation of elastic waves.

Why is it important?
The proposed LS-BR model considers the thermal effects on the fluids and frame and their mutual interaction. The study of wave propagation in a thermoporoelastic medium has many applications in geophysics, particularly, the exploration and development of ultra-deep hydrocarbon resources in western China are usually associated with high-temperature environments.
