PRACTICAL APPLICATION OF THE ALFORD METHOD FOR ESTIMATING ANISOTROPY FROM CROSS-DIPOLE ACOUSTIC LOGGING RECORDS
Annotation
The Alford method is a modern tool for estimating anisotropy from cross-dipole acoustic logging records. The azimuthal angle of the acoustic anisotropy direction is estimated by the minimum cross energy of the converted records. The interval times (speeds) of the fast and slow bending wave pfast, pslow in the forward and reverse directions of anisotropy are estimated using the corresponding transfor-mations. Practical implementation of the method is considered, using the analytical solution of the min-imization problem.
