Is there any need to run a GR/CCL log prior to Perforation?
The GR/CCL run serves the purpose of a drift run, thus giving the operator an idea of the nature of the casing, so that you don’t encounter obstructions when you run in hole with a live gun. It is always better to correlate the CCL, during the gun run, to the GR/CCL log, so that any mistakes, such as off-depth perforations in previous jobs, will not be inherited.
