Thick allochthonous salt masses that pierced the seafloor in the formation of salt-cored folds flowed laterally downdip to form canopies above turbidite exploration targets. This acoustic configuration has created ray path and contrast difficulties for seismologists attempting to carry reservoir reflections beneath the salt and updip to their terminations against it. Initial attempts to correlate these turbidite channel and sheet reservoirs include standard log goodness-of-fit methods, paleontology, surface seismic, and expected hydrocarbon occurrences such as gas-updip-to-oil or oil-updip-to-water. Unfortunately, these methods seldom provide a definitive correlation. Formation pressure data, however, does prove effective in correlating and defining connectivity in these deepwater sediments, especially when exacting pressure gradients and detailed hydrocarbon characterizations have been performed.
