Abstract
Chalks behave weaker at water saturated condition. We
studied this softening effect as a function of Biot’s
frequency ratio, which is a ratio between measured
ultrasonic wave frequency and Biot critical frequency, fc.
Kinematic viscosity of fluid and permeability of rock
determines fc. We observed that rocks saturated with higher
kinematic viscosity fluid are stiffer.
