Topic:
What data is recommended for use in the time/depth pair selection?

Description:
        

Solution:
1. If markers are available, use them. When the marker interpretation and
preferred checkshots exist in the project, the markers (TWT) and TVD may be
used.

2. If checkshots are available but no markers have been entered, seismic
interpretation with a preferred checkshot may be the best option.

3. If the project contains little or no seismic data, time grids may be used.
The time or depth is based on the intersection of the borehole path (derived
from the preferred checkshot) and the grid.

4. If markers exist with seismic time picks, it may be useful to generate
checkshots from the marker TVD and the seismic time pick.
