Database developed in Polish Oil and Gas Institute was designed to give fast and easy access to geological, production, laboratory and technical data obtained during underground gas storage operations. The base has been built in procedures concerning data screening for errors, for filtering to obtain needed information and for material balance. The base contains data from UGS Husów, Wierzchowice, Strachocina. Brzeźnica and Swarzów. AU the data can be used for any type of geological and production analysis. The gathered data allow to run reservoir simulation projects.
