Following the upward trend in domestic oil consumption, the country’s import dependence on oil deliveries mostly from Russia and Kazakhstan has increased. Oil and gas exploration and production are dominated by the state-owned Naftogaz. Prospective fields situated in the Carpathian basin and offshore in the Black Sea-Azov Sea will be more difficult to explore than the existing sites (e.g. in Dnipro-Donetsk) and will require deploying more advanced technologies.
