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

Figure 9

Variation of P-wave and S-wave amplitudes with eccentricity distances a and b when the receiver array is parallel to the borehole axis; they should be listed as (a) variation of S-wave amplitude with eccentricity distance a, (b) variation of S-wave amplitude with eccentricity distance a, (c) variation of P-wave amplitude with eccentricity distance b, and (d) variation of S-wave amplitude with eccentricity distance b.
