Natural gas reserves are exploited in the Regions of Podkarpacie, Małopolska and Lublin.
More than 90% of produced gas is supplied to the networks operated by OGP Gaz-System SA and Polska Spółka Gazownictwa Sp. z o.o., and it is sold by OOH in Warsaw. The remaining output is sold to industrial plants (chemical processing, steel mills, metallurgical and power plants) as well as trade, service and public utility companies.
