MOSCOW, April 29 (Reuters) - Kazakhstan increased oil

exports by 7% year on year to 19.515 million metric tons (1.63

million barrels per day) in January-March thanks to a supply

boost via the Caspian pipeline, Reuters calculations based on

official data and sources showed on Tuesday.

Oil output and exports from Kazakhstan, a top-10 oil

producer, have been in the spotlight as the Central Asian

country has been exceeding quotas agreed by the OPEC+ alliance,

angering several members of the group, including Saudi Arabia.

The Caspian Pipeline Consortium, which exports oil from

Kazakhstan via a Russian Black Sea terminal, has been beset by

drone attacks and wrangling over terminal equipment at Russia's

Black Sea port of Novorossiisk.

Russia has said a CPC pumping station in the south of the

country was attacked by a Ukrainian drone in February, while in

March a nearby oil depot was set ablaze also following a

suspected Ukrainian drone strike.

According to Kazakhstan's Situational and Analytical Center

for the Fuel and Energy Complex at the Energy Ministry,

first-quarter exports via the CPC rose 11% from a year earlier

to 16.388 million tons.

Supplies from the Chevron ( CVX )-led Tengiz oilfield, the

country's largest, jumped 26% in the period to 8.944 million

tons amid the field's expansion, the data showed.

Exports to China via the Atasu-Alashankou pipeline dropped

by 11% in the first three months of the year to 238,000 tons.

Kazakh oil exports via the Soviet-built Druzhba pipeline

through Russia to Germany increased in January-March to 377,000

tons from 300,000 tons in the same period of 2024.

According to Kazakh pipeline operator Kaztransoil, supplies

via the Baku-Tbilisi-Ceyhan pipeline, designed to bypass Russia

as a transit route, declined in the first quarter to 319,206

tons from 364,650 tons in the year-earlier period.
