Abstract

THE PROSPECTIVE COMPLEXES FOR CO₂ STORAGE IN THE BASEMENT OF THE CARPATHIAN FOREDEEP BETWEEN CRACOW AND RZESZÓW

Abstract. The paper deals with the possibility of carbon dioxide storage in the Outer Carpathians and the Carpathian Foredeep between Kraków and Rzeszów. The analysts of the geological structure has revealed the following potential reservoir rocks for CO₂ storage: coarseclastic Cambrian rocks, Middle and Upper Devonian and Lower Carboniferous carbonates, and Permian-Triassic and Middle Jurassic sandstones and conglomerates. Four sub-areas of reservoir rocks have been indicated for the geological storage of CO₂ (1) Sub-area A - the Wadowice-Myślenice reservoir with a surface area of about 850 km² as a potential reservoir for CO₂ represented by a Lower Cambrian sandstone-conglomerate rock complex; (2) Sub-area B - the Gdów reservoir with a surface area of 765.5 km², where the reservoir rocks are Permian-Triassic and Middle Jurassic sandstones and conglomerates: (3) Sub-area C - the Niepołomice reservoir with a surface area of 268.9 km², with the reservoir rocks composed by Devonian carbonates and dolomites; (4) Sub-area D - the Grobla reservoir with a surface area of 422.4 km², represented by Devonian-Lower Carboniferous carbonates and dolomites. The cap rocks for the reservoir rocks in these areas are the Miocene formations of the Carpathian Foredeep, forming a compact cover with a variable thickness exceeding 100 m. In the southern part of the area, these formations are overthrust by the Flysch formations of the Outer Carpathians.
