[[Principles of surface geochemical exploration|Surface geochemical methods]]—specifically, [[Seepage activity|soil gas]] surveys—have proven useful in exploring for these types of traps. The computer compares hundreds of soil-gas ratios very quickly. Also, very sensitive [[chromatographs]] have improved the detection of vertical microseepages of hydrocarbons above these fractured reservoirs. The main method of exploration with this technique is to conduct surveys over a number of known commercial accumulations to establish [[productive signature]]s. Then a survey over the prospect may provide useful information that can be integrated with the other exploration techniques to help locate a drillsite.
