Ultra-deep carbonate reservoir has great burial depths, high reservoir temperatures, a complex and varying formation pressure system, and complicated pore structures. An ultradeep carbonate reservoir in China is the S area of the Tarim Basin, Xinjiang. The effects of temperature, effective stress and porosity on the wave response are described by the Biot-Rayleigh double-porosity model. By combining seismic wave attenuation, P-wave impedance and VP /VS ratio, temperature-pressure-porosity three-dimensional rock physics templates are developed. These templates are calibrated for a range of frequencies and applied to reservoir temperature, effective stress and porosity as predicted by seismic data inversion for the carbonate reservoirs of the S area.
