Depth conversion.
Depth conversion will transfer the time grids to depth grids. In that process we use the velocity cube in the algorithm.
The time grids are probed into the velocity cube and the transition to depth grids occur by sampling velocity values from the cube onto the tme grids.
The standard conversion formula is then used: depth = time x velocity.
Exercise
Transfer time grids into depth grids.
- Copy the time grid folder and paste it into the depth data folder.
- Activate on the pasted grid folder Utilities > Depth conversion of time grids in folder using velocity cube.
- Read the info and browse in the velocity cube.
- Click Execute to perform the depth conversion.
