The example of background determination and mathematical processing of data from surface geochemical survey for the purposes of petroleum exploration



The example of background determination and mathematical processing of data from surface geochemical survey for the purposes of petroleum exploration



Journal of Petroleum Science and Engineering 78(2): 396-406



The paper reports on the methods of mathematical processing of the results of surface geochemical survey applied to petroleum exploration. The results include concentrations of methane analyzed in 1,251 soil gas samples collected from the area over the Wierzchowice gas field (SW Poland). The methods were presented of determining the geochemical background, the anomalous threshold as well as of data normalization and filtration. The advantages were presented of iterative method for determination of background values proposed by the authors. In the authors opinion, selection of the background should be preceded by statistical analysis of each set received during the iteration.
