- Click on the blue (+) button to add the horizon.
- Select Property: TWT
- This will retrieve the TWT property as converted by the velocity.
- Input Formula: h1
- No mathematical operation will be applied to the values (*1).
- In Settings select Vertical: TWT
- This will save the values from step 4 as a TWT property.
- Click Calculate and Create a new horizon.
Note: To convert from TWT to TVDSS, use TVDSS in both the horizon property and vertical settings.
