Impact of Tool Eccentricity on Acoustic Logging Response in Horizontal Wells: Insights from Physical Simulation Experiments

Table 1

Statistical table of P-wave and S-wave velocities and amplitudes in different eccentric states when the receiver array is parallel to the borehole axis, where represents the P-wave velocities and represents the velocities of the S-wave.
