Velocity Model Building (VMB)

$3,130.00

*All commercial products need OpendTect Pro to run

The VMB plugin is used for picking RMO (and NMO) velocities from migrated pre-stack gathers. RMO velocities are used to update the (3D) velocity model in PSDM work flows. Apart from picking velocities on semblance gathers VMB also supports picking anisotropy parameters eta, epsilon and delta and picking of pre-stack events that serve as input to the PSDM-Tomographic plugin.

Two VMB modules are supported: vertical update and horizon-consistent update. The actual creation of velocity models is performed in OpendTect's Volume Builder, which is released in the open source part of the system. Models are constructed from combinations of gridded / smoothed RMO velocities, interval velocities and 3D body velocities.
