Abstract

WIERZCHOWICE - THE GREATEST UNDERGROUND GAS STORAGE (UGS) IN POLAND. PART L: GEOMETRY AND RESERVOIR DESCRIPTION BASED ON 3D SEISMIC SURVEY Summary Wierzchowice - the greatest underground gas storage in Poland, is located in the SW part of the Zechstein Limestone barrier zone near Wrocław. A 3D seismic survey (71 km2) has been recorded in order to evaluate the structure which is considered to be used as a gas storage. Reservoir depth is about 1400 m. During the interpretation of seismic data a special emphasis has been made to highlight the internal reservoir geometry and reservoir description. This study demonstrates the impact of 3D seismic data for the construction of underground gas storage. The information is used as a start-model for simulation, for the estimation of storage capacity and for optimal drilling paths with respect to horizontal wells.
