    The paper presents results of surface geochemical surveys carried out in the area of Underground Gas Storage Mogilno in 2009. The survey has been provided along two measurement lines. The investigations were carried out with application of the method of static chambers and geochemical probe. The geochemical surveys consisted in taking 200 soil-gas samples, in which concentrations of gaseous hydrocarbons were determined. The comparative analysis was conducted in the support about the made statistical profile of measured sets. All comparisons were introduced in the figure of graphs and correlations. As a result of geochemical analysis were found the anomalous hydrocarbon concentrations. In order to determine the leak, it is necessary to perform additional geochemical measurements.

    The paper presents results of surface geochemical surveys conducted in the area of Underground Gas Storage Mogilno in 2008-2009. Collection of test samples was made using a “free” gas method consisting of the current dynamic gases migration. The purpose of this study is to compare changes in concentrations of gaseous hydrocarbons in terms of tightness of the magazine. The comparative analysis was based on the statistical characteristics of the of measured concentrations, changes in average and median quantities, changes in filtered quantities and statistical distributions. All the calculations are presented in graphs and correlations. The results of studies have highlighted the increased concentration of gaseous hydrocarbons in the near-surface zone in 2009. This confirmed the need for further surface geochemical surveys in the area of Mogilno.
