Summary:
P212 Effects of source mismatch on multipole logging JOONGMOO BYUN 1 . M. NAFI TOKSÖZ 2 AND RAMA RAO 2 Abstract 1 The effects of mismatched multipole sources were investigated. Multipole sources considered here are those that they are constructed of monopoles with appropriate sign combination. To simulate mismatched dipole and quadrupole sources we made the amplitude of one of monopoles smaller than those of the other monopoles. The dipole and quadrupole component were obtained with four monopole receiver array system by subtracting or adding appropriate responses. Mismatched dipole source excites nondipole modes in addition to the flexural mode. The
