30-45 degrees: North or top of hole according to preference

45-60 degrees: Should be oriented to Top of hole, but orientation to North can be ok

> 60 degrees: Must be oriented to Top of hole

20.Next

21.Next

Create dynamic image

22.Deviation 0-30 degrees: Wireline images usually oriented to North

30-45 degrees: North or top of hole according to preference

45-60 degrees: Should be oriented to Top of hole, but orientation to North can be ok
