MOSCOW, Oct 22 (Reuters) - A Chevron ( CVX )-led

consortium developing Kazakhstan's largest oilfield Tengiz will

resume oil exports via the Baku-Tbilisi-Ceyhan pipeline in

November, three industry sources said on Wednesday.

The pipeline runs through Georgia to Turkey and is used

mainly to export oil from the Azeri, Chirag and Guneshli

oilfields, which are operated by BP.

Organic chloride contamination in Azeri BTC crude cargoes

was discovered in July, causing several days' delay in loadings

from Turkey's BTC Ceyhan. The TCO consortium suspended exports

on the route the following month.

While Kazakhstan resumed oil supplies via the pipeline last

month, Tengiz stayed away. One of the sources said the

consortium would ship 130,000 metric tons, or more than 1

million barrels, of oil next month.

The TCO consortium and Azerbaijan's state energy company

SOCAR did not reply to requests for comment.

The pipeline is also used by Kazakhstan to lessen its

dependence on Russia as a main exporting route. More than 80% of

Kazakhstan's oil exports are shipped by the Caspian Pipeline

Consortium via Russia's Black Sea Yuzhnaya Ozereevka terminal.

Kazakhstan usually supplies oil to BTC by tankers from the

port of Aktau, mainly from Tengiz, but also from the Kashagan

oilfield.

Oil exports via the BTC pipeline declined to 20.569 million

tons in the first nine months of the year, from 21.681 million

in the same period of 2024, according to Azerbaijan's official

data.
