MOSCOW, Feb 2 (Reuters) -

Oil production at Kazakhstan's giant Tengiz field continued

to recover in the past few days after a mid-January outage, two

sources familiar with operational data said.

Tengiz, which accounts for nearly 40% of Kazakhstan's

output, was shut on January 18 ‌after a fire in electrical

equipment, reducing the Central Asian nation's total oil supply

at a ​time when exports were already constrained by disruptions

on its main pipeline ‍route.

Oil output at Tengiz rose to 23,000 metric ⁠tons (183,000

barrels) on Sunday ⁠from 14,900 tons (118,000 barrels) on

Saturday, the sources said. Production is expected to continue

increasing and reach ‌54,000 tons (430,000 barrels) by Wednesday,

the sources ​said.

In January, Tengiz's output fell threefold from December to

234,000 barrels per day, according to data from the Situational

and ⁠Analytical Centre of the Fuel and ‍Energy ​Complex (SAC FEC).

The field produced 2.694 million tons in December, equivalent to

691,700 bpd by Reuters calculations.

Output at Tengiz hit a record 3.7 ‍million tons in August

2025, SAC FEC data shows.

Tengizchevroil (TCO), the Chevron ( CVX )-led operator, said

it is gradually ramping up production as conditions allow but

does not comment on specific operational or commercial details.

MAINTENANCE CURBS OUTPUT

Kazakhstan's total oil and condensate production fell to

1.27 million bpd in January, from 1.86 ​million ‍bpd in December

and 1.87 million bpd a year earlier, a source said, citing SAC

FEC data.

The energy ministry did not immediately ​respond to a Reuters

request for comment.

Two other major fields also saw declines in January.

Production at Kashagan oilfield was down 33% to 260,000 bpd,

while Karachaganak oil output was down 13% to 198,300 bpd.

One of the sources said Kashagan's decline was linked to

maintenance. NCOC, the Kashagan operator, did not respond to ​a

Reuters request for comment.

The decline in Kazakhstan's overall output in January was

driven by restrictions on the Caspian Pipeline Consortium (CPC)

export route - after infrastructure was damaged in a drone

attack - as ‍well as the outage at Tengiz.
