... 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...

... is raised by iterating inversion via multi-scale seismic inversion. The constraint of low frequency can improve resolution furtherly by proposed method. More precisely, low frequency information of P-wave impedance is obtained by large scale inversion. On this basis, high frequency information of P-wave...
