Geological model of Lobodice underground gas storage facility based on 3D seismic interpretation
The Lobodice underground gas storage (UGS) is developed in a natural aquifer
reservoir located in the Central Moravian part of the Carpathian Foredeep in the Czech
Republic. In order to learn more about the UGS geological structure a 3D seismic survey
was performed in 2009. The reservoir is rather shallow, 400–500 m below the surface.
This article describes the process workflow from the 3D seismic field data acquisition to
the creation of the geological model. The outcomes of this workflow define the geometry of
the UGS reservoir, its tectonics and the sealing features of the structure. Better geological
knowledge of the reservoir will reduce the risks involved in the localization of new wells
for increasing UGS withdrawal rates.
