    "abstract": "In this paper, the reservoir is modeled by homogeneous two-phase media based\non BISQ model. We focus on the effects of the squirt flow on the fundamental\nguided waves propagation in borehole embedded in saturated porous media excited\nby monopole, dipole and quadrupole point sources. The full waveforms acoustic\nlogging in a fluid-filled borehole are simulated. The curves of velocity\ndispersion, attenuation coefficients and excitation of the fundamental guided\nwaves have shown that velocity dispersions are almost independent of the\ncharacteristic squirt flow length, attenuations of guided waves are enhanced\ndue to the squirt flow, and excitations of guided waves are decreased due to\nthe squirt flow. It is possible to estimate the characteristic squirt flow\nlength by attenuation coefficients of the guided waves from acoustical logging\ndata.",
