Evidence of Extreme Overpressure Generated by Source Rock Maturation: Case Study, Deep-Offshore GOM, USA

Only very few overpressure prediction accounting for hydrocarbon generation processes are actually based on real well results and data. This paper will show a case study example where both compaction disequilibrium and hydrocarbon generation participate to the generation of overpressures. This case study was built using standard log derived method as well as drilling observations and well events.
