Abstract

Summary

An indicator of expulsion efficiency obtained from gases extracted from mudstone correlates with the degree of microquartz cementation. Cemented samples have stronger retention of hydrocarbons. The strongest degrees of expulsion are observed in samples that lack cements and have diagenesis dominated by compaction. This suggests that mudrock compaction remains an active process in the zone hydrocarbon generation.
