Vertical profile of the 3D velocity model along GRT-1 overlaying a vertical South–North section of the 3D P-wave velocity model next to GRT-1 and GRT-2 wells (red curves). The red velocity profile indicates the Vp derived from the VSP, the blue velocity profile indicates the Vs derived from the VSP and the Vp/Vs ratio of the full sonic (see text for further explanations). The Vp and Vs measured by the full sonic log are presented for comparison in dark and light gray, respectively
