Above a specific SGR value, 100% of all faults in the Gulf Coast cross-leak oil. Below a specific SGR value, 100% of the faults cross-seal oil. A narrow transition zone defines the threshold for seal/leak. Separate thresholds exist for cross-seal/-leak, dip-seal/-leak, oil, and gas. | Above a specific SGR value, 100% of all faults in the Gulf Coast cross-leak oil.
