Elastic-Impedance-Based Fluid/Porosity Term and Fracture Weaknesses Inversion in Transversely Isotropic Media with a Tilted Axis of Symmetry

Figure 11

Inverted azimuthally anisotropic EI data with five azimuths, where (a) is the near-angle EI data, (b) is the middle-angle EI data, and (c) is the far-angle EI data. Note that the five azimuths are 20° (ranged from 0° to 40°), 55° (ranged from 35° to 75°), 90° (ranged from 70° to 110°), 125° (ranged from 105° to 145°), and 160° (ranged from 140° to 180°), respectively.
