ABSTRACT:
The paper provides research and results for underground storage of gas (UGSG) in limestone rocks, which were carried out in Slovenia – Central Europe. The areas was geological surveyed and in addition structural boreholes were drilled up to the depth of 350 m. The cores were logged with emphasis on stratigraphy, layering, rock joints, tectonic zones, RQD….and addition characteristics samples were taken for the laboratory rocks geomechanical characteristics investigations. In boreholes geophysical, pressiometric and hydro-geological investigations were also carried out. In the area where the researches have been carried out, limestone, dolomites and breccias are prevalent. Storage should be built for pressure between 15 and 20 MPa. Explorations confirmed that there is a possibility of building a high-pressure underground storage of gas (UGSG) and using applied mechanics for design LRC (Lined Rock Cavern) technology. The construction of underground storage facilities for natural gas storage is important in cases, where the gas supply does not meet the required capacity for operation of the thermal power plant.
