Naftogaz subsidiary Ukrtransgas has begun reconstruction of the gas dehydration installation at the Uhersk underground gas storage facility (UGS), in which it will invest UAH 144M ($5.15M), reported Ukrtransgas. Renovation of the system, which directly affects the quality of gas injected and withdrawn to/from UGS, will improve the technical performance of the gas storage facility. As a result, it is expected that UGS will minimize the impact on the environment and bring its operation closer to current European standards.
