Used a 3D finite-difference code to simulate the radiation and reflection wavefields of a planar transducer and computed the angle-dependent reflection coefficients of anisotropic rock samples in the ultrasonic frequency range (around 1 MHz). The work contributed to the interpretation of seismic azimuthal data and experiments for estimating the dynamic elastic properties of complex rocks from angle-dependent ultrasonic reflection measurements.

Finite-Difference Modeling of Borehole Acoustic Waves in Porous Formations

Developed an advanced multi-physics finite-difference method to simulate elastic wave propagation in porous formations, incorporating elastic, poroelastic, and poro-crack media, and accounting for wave dispersion and attenuation caused by both Biot and squirt-flow mechanisms. The poroelastic finite-difference method and an effective-wavenumber analytical method were used to model Stoneley wave reflection and transmission coefficients across permeable and fractured formations, improving the interpretation of borehole acoustic measurements and the accuracy of reservoir characterization.
