Adjoint-State Borehole Acoustic First-Arrival & Reflection Traveltime Tomography
Efficient adjoint-state traveltime tomography to reconstruct near- and far-borehole velocity from monopole first and reflected arrivals.
Efficient adjoint-state traveltime tomography to reconstruct near- and far-borehole velocity from monopole first and reflected arrivals.
A fast 3D eikonal solver for analyzing azimuthal first-arrival times and slowness logs in high-angle and horizontal wells.
3D finite-difference simulation of transducer radiation and reflection to compute angle-dependent reflection coefficients of anisotropic rocks.
A multi-physics finite-difference method for elastic, poroelastic, and poro-crack media, capturing Biot and squirt-flow dispersion and attenuation.
