... are used to orient the horizontal components towards the fast and slow shear directions. The separated S 1 and S 2 wavefields are processed to generate PS 1 , PS 2 , S 1 S 1 , and S 2 S 2 corridor stacks. Conventional PP corridor stacks are generated by processing the vertical component. The technique...

Fig. 4 From the enhanced upgoing wavefield (ii), a corridor stack is generated (iii), which is then inverted to generate an AI profile (blue, converted after in a velocity profile) ahead of the well TD (at 5.33 seconds). On the right, the green curve is the velocity profile obtained from the inver... More
