Safe and economical exploration drilling largely relies on appropriate analyses and estimation of the overpressures in the subsurface. In contrast, incorrect predictions of these abnormal pressures can cause delays and increase costs due to failures of rock formations, lack of drilling mud circulation, collapse of the casing, and closures for differential pressures.
