The flow resistance of faults can make or break an exploration play or undermine the economics in a developing field where the decision whether to drill one or two wells depends on communication across fault-bound compartments. Well-developed workflows reduce the uncertainty in the precise behavior of hydrocarbon flow across faults and improve risk assessment for making more economically sound decisions.
