Geological evaluation of the underground gas storage Dolní Dunajovice
Original language description
The presentation is devoted to the issue of the underground gas storage Dolní Dunajovice which is with an average length of 8 km and a width of 800 m the biggest reservoir in the Czech republic. In the presentation, I would like to define and describe the area of interest, geological development, including the history of the geological building of the southern part of the Carpathian Foredeep in Moravia, especially Miocene, when the Eggenburgian Dunajovice sandstones were laid and which create gas storage horizon. The actual research is built on studying drilling cores and well logging measurements. Examined are the contents of heavy minerals mainly zircon, tourmaline, staurolite and rutile and their probable origin from metapelites of Moravicum and the Cadomian granitic rocks of the Brno massif. Also, the representation of grain fractions is evaluated and which in combination with the variable contains of organic matter and glauconite reflects a variable sedimentation environment, mainly at delta topset. Facial analysis with interpretation is also an output of the core study and is evaluated in combination with gamma-ray logging in the whole area of the reservoir. In addition to the drilling cores and the well logging data, the developed gas reservoir geological structure maps are also evaluated.
