Asymmetric source acoustic LWD for the improved formation shear velocity estimation
Most acoustic LWD tools generate a single pure borehole mode (e.g., dipole or quadrupole) to estimate the formation shear velocity. We propose an approach where many borehole modes are generated and all the modes are used simultaneously to obtain a better shear estimate. In this approach we find...
