Abstract
A method for processing sonic data measured with a downhole tool is provided. The method comprises acquiring dipole wave data measured by a dipole acquisition in multiple firing, and estimating at least one of formation anisotropy properties based on the multiple firing dipole data. The at least one of formation anisotropy properties may be derived by Alford rotation processing. The method may further comprise processing with inversion of an orthogonality error angle of the firing data in two dipole firings and/or providing a quality control with the estimating result based on sonic measurements in a pump-off period.
