Ukraine has increased attacks on Russian energy facilities in recent months as peace talks have failed to make progress.

Following is a summary of the attacks and their impact:

*SYZRAN

Rosneft's Syzran refinery has suspended oil refining after drone attacks on April 18 damaged processing equipment, two industry sources told Reuters.

The Syzran oil refinery is able to process 8.5 million metric tons per year, or around 170,000 barrels per day.

It processed 4.3 million tons of crude in 2024, producing 800,000 tons of gasoline, 1.5 million tons of diesel and 700,000 tons of fuel oil, according to industry sources.

*NOVOKUIBYSHEVSK

Primary oil processing at Russia's Rosneft-operated Novokuibyshevsk refinery has been halted since April 18 after a Ukrainian drone attack, two industry sources said.

In 2024 the refinery processed 5.74 million metric tons of crude oil, 1.10 million tons of motor gasoline, 1.64 million tons of diesel fuel and 1.27 million tons of fuel oil, industry sources said.

*TUAPSE

Russia's Tuapse oil refinery, which sells most of its products for export, halted operations following a Ukrainian drone attack on April 16, two industry sources said on Tuesday.

It has production capacity of around 12 million metric tons per year, or 240,000 barrels per day. It produces naphtha, diesel, fuel oil and vacuum gasoil.

NORSI

NORSI, Russia's fourth-largest oil refinery, owned by Lukoil LKOH.MM, suspended operations on April 5 following a Ukrainian drone attack, two industry sources said.

NORSI, which is also Russia's second-largest producer of gasoline, can process 16 million metric tons of oil per year, or around 320,000 barrels per day.

KIRISHI

Russia's Kirishi oil refinery may restart some production within a month, sources say. It halted processing at the end of March following Ukrainian drone attacks that caused fires.

According to sources, three of the four primary units are expected to return to operations, adding up to around 60% of the refinery's nominal primary capacity.

Last year, Kirishi produced 2 million tons of gasoline, 7.1 million tons of diesel, 6.1 million tons of fuel oil and 600,000 tons of bitumen.

UST-LUGA PROCESSING PLANT

Russian energy company Novatek <NVTK.MM> has suspended gas condensate processing and naphtha export loadings at its Ust-Luga complex after drone attacks caused a fire, three market sources told Reuters.

The Ust-Luga complex's three processing units, each with a capacity of 3 million tons a year, refine stable gas condensate into light and heavy naphtha, jet fuel, ship fuel oil and gasoil. In 2025, the complex processed 8.0 million tons of gas condensate, company data show.

UFA

Ukraine's military said it had struck Russia's Bashneft-Novoil oil refinery, over 1,400 km (870 miles) from the Ukrainian border.

It can process more than 7 million tons of oil per year.

SARATOV REFINERY

The Saratov oil refinery, controlled by Rosneft ROSN.MM, was hit by a drone on March 21 and its crude distillation unit has been shut down since the attack, according to sources.

In 2024, the refinery processed 5.8 million metric tons of oil, accounting for 2.2% of all Russia's oil refining.

ILSKY REFINERY

A fire broke out at the Ilsky oil refinery in southern Russia on February 17 as a result of drone attacks. The blaze was fully extinguished by the next day, according to regional officials.

The Ilsky refinery, with an annual processing capacity of 6.6 million tons of oil, is export-oriented.

VOLGOGRAD REFINERY

The Volgograd refinery, owned by Lukoil LKOH.MM, was shut on February 11 as a result of drone attacks, according to sources.

The drones hit, among other facilities, the primary oil processing unit CDU-1 whose capacity of 18,600 tons per day accounts for around 40% of the refinery's total. In 2024, the Volgograd refinery processed 13.7 million tons of oil.

UKHTA REFINERY

A fire broke out on February 12 at the Ukhta refinery, owned by Lukoil, following a drone attack, according to regional officials.

According to sources, the primary oil processing unit CDU-1 caught fire. The unit has a capacity of about 6,000 tons per day, or approximately one-third of the refinery's total.

In 2025, the Ukhta refinery in northern Russia processed around 3 million tons of oil.

AFIPSKY REFINERY

A fire occurred at the Afipsky refinery in southern Russia on January 21 as a result of drone attacks, according to regional officials.

The refinery is mostly focused on exports. It processed 7.2 million metric tons of crude oil, or 144,000 barrels per day, in 2024.

PORTS AND TANKERS

Ukrainian drones struck an oil-pumping and dispatch facility in Russia's Samara region overnight, an official from Ukraine's SBU security service said.

Kazakhstan said early in April CPC oil exports via the Black Sea were stable after Russia reported an attack. U.S. oil major Chevron said crude oil exports from the vast Tengiz field had been uninterrupted.

Ukrainian drones sparked a fire at Russia's Sheskharis oil terminal early in April.

A portion of an oil pipeline at Russia's Baltic Sea port of Primorsk has been damaged in a Ukrainian drone attack early this month, local governor Alexander Drozdenko said.

Primorsk, one of Russia's largest export gateways, which can handle 1 million barrels per day, lost at least 40% of its storage facilities in Ukrainian drone attacks last month.
