fundamental controls on the existence of petroleum systems. This evolved into a macro-framework understanding of hydrocarbon systems produced as a result of source rock maturity and the existence of fluid potential energy fields in a basin. This has provided a key to understanding the creation of overpressured and underpressured “basin centered” or “deep basin” oil and gas accumulations currently being exploited in the Rockies. Bibliography Meissner was a prolific technical writer and authored over 45 publications and papers focusing primarily on hydrocarbon generation, migration and accumulation.
