The article presents evaluation of the emission of methane and carbon dioxide into the atmosphere in the closed area of oil field in Siary. The investigation consisted on looking for hand made oil wells and take sampling solid gas, with application of the modification method of static chambers of the oil wells and closed oil wells. A total of 31 soil gas samples were collected, which analyses were carried out at the Laboratory of Department of Fossil Fuels, AGH University of Science and Technology in Kraków. The measurements included changes concentrations of hydrocarbons and carbon dioxide, which naturally escape to the atmosphere from the land surface and above hands made oil wells. Dynamics of its concentrations methane from the surface to the atmosphere amount from –0.87 to 119.92 [ppm min-1] and carbon dioxide – 0,005 to 0,053 [%vol.·min-1]. Calculated maximum emission of methane amount almost 19000 [mg·m-2·d-1], and maximum emission of carbon dioxide 225799 [mg·m-2·d-1].

The purpose of this study was to evaluate the impact of the liquidated oil well on the environment. The survey was conducted around the„Barbara” oil well in Siary. For this purpose, 10 samples of soil gas from the measuring points distributed around the oil well, were collected using free air method. Then the samples were transported to the Laboratory of the Department of Fossil Fuels at AGH University of Science and Technology in Krakow, where they were analyzed using a gas chromatograph. The studies were obtained concentrations of alkanes C1-C5, alkenes C2-C4, carbon dioxide and hydrogen. In the three measuring points anomalously high concentrations of alkanes, particularly methane and increased concentration of carbon dioxide were stated. The highest concentration of methane was 438,421 ppm, and carbon dioxide 5.843% vol. These concentrations were observed at a distance of about 15 m from the center of oil well, hence it is difficult to speak of its direct negative impact on the environment.
