Evaporites and their Role in Petroleum Exploration

Estimated Time to Complete:

2 hours 20 minutes

(average of 20 minutes per Subtopic)

Describes characteristics of evaporites and examines their relationship to hydrocarbon accumulations, including their role as source beds, reservoirs, traps and seals. Discusses evaporite mineralogy and diagenesis, as well as analysis and identification techniques. Field examples illustrate occurrences, evaluation and significance of evaporite structures.
