According to elastic reciprocity theorem, the shear-wave radiation from a borehole dipole source is reciprocal to the reception in the source orientation of the borehole fluid displacement caused by the incidence of plane shear waves upon the borehole. Consequently, the borehole radiation pattern can be utilized to compute the borehole reception directivity. The results show that the radiation away from borehole can be accurately computed using an asymptotic solution in the far-field of the borehole. The use of the reciprocity theorem and the asymptotic solution greatly reduces the computational effort in the reflection survey simulation. The simulation results agree well with those from a 3D finite difference elastic wave simulation. The modeling results also show that the SH-wave component from the dipole source is a dominate component for the dipole shear-wave imaging. Simulation and processing results of cased-hole dipole reflection survey data also demonstrate the feasibility of applying the borehole shear-wave imaging technology in cased boreholes. The results of this work provide a fast and accurate algorithm for simulating the dipole-shear wave reflection survey along a borehole.
