Paper presented at the SEG International Exposition and Annual Meeting, October 11–16, 2020
Paper Number: SEG-2020-3412339
... Understanding the effects of pressures, fluid content, and fluid distributions on the elastic wave propagation in reservoir rocks is of great importance in guiding oil and gas exploration. A new theoretical model for the attenuation of partially saturated porous rock was developed by combining...
