Introduction

Depth conversion will transfer the time grids to depth grids. In that process we use the velocity cube as input. The time grids are probed into the velocity cube and the transition to depth grids occurs by sampling velocity values from the cube onto the time grids.
The standard conversion formula is then used: depth = time x velocity.

Exercises:

Exercise

Transfer time grids into depth grids

  1. Copy the time grid layer model and paste it into the Depth data folder.
  2. Right click the layer model that you copied into the Depth data folder and select Utilities > Depth conversion of time grids in folder using velocity cube.
  3. Read the info and browse in the velocity cube.
  4. Click Execute to perform the depth conversion.
Exercise

Display depth grids

  1. Display the same time grid and depth grid to see how it is shifted.
  2. Activate Initialize layer model into Workspace on the depth grid folder.
  3. Make a new cross section folder and perform cross sections in all directions.
