The data suggested Ukraine would import 7.1 mcm of gas from Hungary, 7.3 mcm from Slovakia and 1.8 mcm from Poland.
Ukraine began sharply increasing its gas imports last week after a series of Russian missile attacks in recent months targeted Ukrainian gas sector facilities.
In January Russia launched scores of missiles and drones at Ukraine's western Lviv region where gas storage facilities are located and in the Kharkiv region, the main Ukrainian gas production area.
Ukraine can keep around 30 billion cubic meters of gas in storage, but the country has stopped reporting the volume of gas in facilities, which have been the target of regular Russian missile attacks since Russia's full-scale invasion in February, 2022.
Both the drop in gas production and difficulties with fuel extraction from underground storage facilities may force Kyiv to increase the volume of imports.
Ukrainian energy minister German Galushchenko told Interfax Ukraine news agency last week that the country could need to import around one billion cubic meters of gas during the current heating season.
The former head of the transit operator, Serhiy Makogon, said last month that current Ukrainian daily gas consumption was about 110 mcm and was covered by 52 mcm of production and 58 mcm from storage.
