We studied second-order wave propagation systems for vertical transversely isotropic (VTI) and tilted transversely isotropic (TTI) acoustic media with variable axes of symmetry that have their shear-wave speeds set to zero. Acoustic TTI systems are c

We derive and compare first-order wave propagation systems for variable-tilt elastic and acoustic tilted transversely isotropic (TTI) media. Acoustic TTI systems are commonly used in reverse-time migration. Starting initially with homogeneous vertica

Summary Second-order pseudo-acoustic systems are commonly used in reverse-time migration in tranversely isotropic media to model quasi-P-wave propagation. Systems with the shear wavespeeds set to zero can suffer from instabilities. Systems with posit

A 2-D elastic dataset over a complex geologic model was used to investigate and benchmark demultiple processing capabilities at seven seismic processing vendors. Results show the free surface related multiple elimination (SRME) method to be superior
