What is it about?
Fault (Zone of fractures) which are enclosed within the Overpressurd formation will behave as a tilted permeabile body with pressured fluids in it, which shall bring drilling surprises and cause issues in terms Safety, Cost and Delayed Time.

Why is it important?
It is important to know likely chances of these kind of secondary overpressures, so that well planning can be optimized avoiding such zones.
Perspectives
Pore pressure prediction process needs to be strengthened beyound the general estimation process by interesting structural implications and possible hydrodynamics in well planning to a avoid surprises.
