Deepwater reservoirs, those in water depths ranging from 1000 m to more than 3000 m, often consist of young turbidite sediments associated with early hydrocarbon charge, overpressure buildup, and seal with retarded diagenesis. Deepwater sands maintain shallow properties even at great depths (e.g., 18 000 ft) but these weakly cemented sands—with a history of progressive compaction and cementation—differ from surface sediments.
