Description
Delta is one of the Thomsen's anistropic parameters. The other two are Epsilon and Gamma. Besides PSDM Imaging, the user can use HTI delta estimation module to calculate/estimate the delta value in g-Platform.
If the axis of symmetry is along the horizontal then we call it as Horizontal Transverse isotropy. In HTI, velocity is slow in the horizontal direction and we expect faster velocities in the vertical direction.
This module requires two velocity fields.
1. Isotropic Velocity model
2. Vertical velocity model (check shots)
3. Horizons
The final output from the HTI delta estimation module should be "Delta parameter by layer"
