How abnormal pressures affect hydrocarbon exploration, exploitation
Abnormal pressures, principally overpressure but also underpressure, have been discussed in numerous papers. These have concentrated on overpressure generating mechanisms and the ability of abnormal pressure prediction. This article will examine the information that can be deduced by the knowledge that a basin is abnormally pressured and how this can affect exploration risking, reserves estimation, and hydrocarbon production. Abnormal pressures consist of both underpressure and overpressures.
