Surface geochemical methods—specifically, 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 signatures. Then a survey over the prospect may provide useful information that can be integrated with the other exploration techniques to help locate a drillsite.
