Drozdenko said on Sunday more than 60 drones were downed overnight over Russia's northwest Leningrad region.
There was no oil spill following the attack on Primorsk, a major oil exporting outlet, and the fire was extinguished, he said on the Telegram messaging app.
Primorsk, one of Russia's largest export gateways, has capacity to handle one million barrels per day of oil supply.
It has been hit multiple times in recent months as Ukraine has stepped up attacks on Russian energy infrastructure and other targets, as US-brokered talks to end the Ukraine war have stalled.
Ukrainian forces also struck two shadow fleet tankers in waters at the entrance to the Russian Black Sea port of Novorossiysk, Ukraine's President Volodymyr Zelenskiy said on Sunday.
"These tankers had been actively used to transport oil - not anymore," Zelenskiy said on Telegram.
"Ukraine's long-range capabilities will continue to be developed comprehensively - at sea, in the air, and on land."
Other Russian regions also reported drone attacks on Saturday and Sunday.
Moscow regional governor Andrei Vorobyov said on Saturday evening a 77-year-old man had died in a village following a drone strike.
And Sergei Sobyanin, the mayor of the city of Moscow, said four drones were downed on their way to the Russian capital.
Vasily Anokhin, the governor of the western Smolensk region, said three people, including a child, were injured on Sunday after a drone attacked an apartment block there.
Russian troops were, meanwhile, inching towards the city of Kostiantynivka in Ukraine's eastern Donetsk region, Ukraine's top army official said on Saturday.
