On the base of 388 samples of the Carpathian sandstones analyses of intergranular and fracture permeability and porosity were performed, as well as granulometric analyses and investigations of diagenesis processes. Pore space of these sandstones was created by diagenetic processes. Mechanical compaction and cementation dominates but dissolution played role in creating of secondary porosity. Conducted investigations thrown a new light on filtration properties of moderate porosity sandstones. Intergranular permeability are very low but fracture porosity can reach relatively high values (up to 50 mD) in great part of investigated sandstones. This fact opens new opportunities in exploration of such type of sandstones in the Carpathian flysch.

In the master's thesis the geological features of building underground storage facilities in depleted gas fields, and the impact of the miscellaneous of collectors for technological exploitation of UGS were studied. The object of study in the work is the underground gas storages (UGS) of Western oil and gas region - Oparske, the productive horizons of which are characterized by considerable heterogeneity of reservoirs on the cut and the area. In the work contains information about the geological industrial features of the studied underground gas storage facilities. Developed the method of studying the geological heterogeneity of the reservoir and recommended its use for efficient operation of underground storage facilities. It was made the analysis of exploitation of gas deposits in the Oparske underground gas storage. It was analysed the impact of heterogeneity of collectors for technological exploitation of gas, and thus, the performance of wells and volume of active gas in UGS.
