Treść
Polish shale formations are varied and their evaluation based on chemical and isotopic composition analyses may be very useful. On the basis of the δ13C value of methane, ethane and propane estimation of source rock (from which the gas was generated) thermal transformation degree can be performed. This may lead to recognition of the areas within basin with high hydrocarbon potential. Analysis of the chemical composition of the gas samples were made using the Agilent model 7890 A chromatographs, equipped with TCD and FID detectors. Carbon and hydrogen isotopic composition of individual gaseous hydrocarbons was determined using isotope Delta V. Advantage spectrometer with chromatograph Trace GC Ultra from Thermo Scientific. Analyses of chemical and isotopic composition were performed for gas samples from cores degassing. Total amount of 23 samples was acquired during the drilling of two wells located in north (well A – Baltic basin, 9 samples) and south (well B – Lublin basin, 14 samples) of Poland. Both wells were exploring Silurian and Ordovic ian shale formations. The isotopic composition of methane carbon from well A samples corresponds to the beginning of the oil window and from well B samples corresponds to the gas window. In order to accurately determine the type of gas δ13C and δD values were plotted on Peters diagram [1]. Respective data of gases from well A are located in the fields of mixed and oil related gases, while from well B they are located in the fields of condensate and oil related gases. Gases from well located in north of Poland were generated on considerably lower thermal maturity level of organic matter than gases from well located in south of Poland. Data from well A correspond to 0.8 to 1.0 % vitrinite reflectance thermal maturity and from well B (four samples without roll-over effect) corresponed to 1.0 to 1.3 % vitrinite reflectance thermal maturity. Ten samples from well B, has inverted isotopic composition – roll-over effect. Polish shale formations are varied and natural gas composition analyses can be helpful for correct prediction of type and amount of natural gas in shale formation. This study was supported by The National Centre for Research and Development (Blue Gas project “MWSSSG” no BG1/MWSSSG/13).
