Create a Velocity Picking

Create a new velocity picking

Create new velocity picking
  1. In the Control Panel, open the Imaging tab.
  2. At the tab header, click the blue "+" icon and select New process.
  3. In the Create Process window, select Picking: Manual.
  4. The Configure Velocity Picking window will be displayed.
  1. Type a Name for the Velocity Picking.
  2. Select the Shared check box if you want to make the velocity picks visible to other users.
  3. At Pre-NMO Gathers, select an offset gather volume to be used for picking. You must choose a gather that is NOT an NMO-corrected gather volume.
  4. Select the Pick effective η (eta) check box to also conduct anisotropic RMO imaging (eta picking).
  5. At the 3D Picking Grid section, type a value for the Inline and Crossline increments (you can only use increments of 4) to specify the grid on which to conduct your velocity picking. You can see the resulting Spacing on the right.
  6. At Anchor, type the values to anchor the grid.
  7. Click on Default Grid to set the spacing based on the default grid. The default spacing is set at 1km x 1km.
  8. Click OK to confirm the velocity picking configurations. A new velocity picking item will be available as part of the episode in the Imaging tree, and the Velocity Picking window will be displayed.

See Using the Velocity Picking Window to begin velocity picking.

The output from the velocity picking can be found in the Volume tab, including the picked velocity, automatic stack and semblance. You can change the display of the output parameters like any other volume.
