This aproach is not good for anomalous gelogical areas and/or unconsolidated samples.
If you want the presures for production analysis or similar then the formation pressure has to be measured and the overburden has to be calculated from logs (density log)
first thanks a lot for your reply
seconded what is the meaning of anomalous geological areas and if you do not mind how can I calculate overburden from density log in details
thanks brother
