摘要
A system and method for determining shear wave anisotropy in a vertically transversely isotropic formation is disclosed. The method includes generating a broad band Stoneley wave and a broad band dipole flexural wave. The broad band Stoneley wave and a broad band dipole flexural wave may be generated at a logging tool located within a wellbore. The method also includes receiving at the logging tool first data corresponding to the broad band Stoneley wave and second data corresponding to the broad band dipole flexural wave. The method also includes determining a vertical shear wave constant, c66, by at least applying an inversion algorithm to the first data and the second data.
