Kazakhstan Oil: Production, Reserves & Role in the Market
Kazakhstan produces about 2.05 million barrels of crude per day (2025) and holds ~30.0 billion barrels of proven reserves (#12 worldwide). Central Asia's dominant oil producer, Kazakhstan's output is anchored by the giant Tengiz field and its exports flow almost entirely through a single pipeline across Russian territory — a chokepoint that has repeatedly become a geopolitical pressure point since 2022.
Key Figures

|---|---|---|
| Crude production (#11 of tracked) | 2.05 Mb/d | 2025 · EIA |
| Proven reserves (#12 worldwide) | 30.0 Bn bbl | 2023 · EIA estimate |
| Key field | Tengiz — one of the largest oil fields in the world, operated by Chevron-led Tengizchevroil | |
| Main export route | CPC pipeline (Caspian Pipeline Consortium) to Novorossiysk, Russia — carries the large majority of Kazakh exports | |
| OPEC+ status | Non-OPEC member of the wider OPEC+ alliance, alongside Russia | |
| Quota compliance | Has repeatedly produced above its OPEC+ quota as the Tengiz expansion ramped up | OPEC+ communiqués |

Kazakhstan's Pipeline Dependence
Tengiz and the CPC chokepoint
- The Future Growth Project at Tengiz, completed in 2024–2025, added significant new capacity — output that then has almost nowhere to go except the CPC pipeline.
- The CPC pipeline runs roughly 1,500 km from western Kazakhstan to the Russian Black Sea port of Novorossiysk, making Kazakhstan's exports geographically dependent on Russian territory despite the countries' separate OPEC+ standing.
- Alternative export routes (Baku-Tbilisi-Ceyhan via Azerbaijan, rail to China) exist but carry only a small fraction of volumes.
What to watch
- CPC pipeline disruptions — storm damage, drone strikes near Novorossiysk, or Russian regulatory actions have periodically threatened flows since 2022.
- OPEC+ quota disputes, since Kazakhstan's Tengiz-driven output growth has repeatedly outpaced its allotment.
- Progress on alternative export routes that would reduce reliance on the CPC pipeline.

Kazakhstan Oil FAQ
How much oil does Kazakhstan produce?
Kazakhstan produces about 2.05 million barrels per day of crude oil (including lease condensate, 2025), ranking #11 among the countries tracked here. Source: EIA international statistics.
How much oil does Kazakhstan have in reserves?
Kazakhstan holds roughly 30.0 billion barrels of proven crude reserves (EIA estimate, 2023), the #12 largest in the world. Proven reserves shift with prices and technology — see the caveats on the oil-reserves page.
Why does Kazakhstan's oil depend on Russia?
The CPC pipeline, Kazakhstan's main export route, runs from its western oilfields through Russian territory to the Black Sea port of Novorossiysk. Since the large majority of Kazakh crude exits this way, disruptions inside Russia — whether infrastructure damage or regulatory action — can directly cut Kazakh export volumes even though Kazakhstan is not itself sanctioned.
Is Kazakhstan an OPEC member?
No. Kazakhstan is a non-OPEC member of the broader OPEC+ alliance, alongside Russia. It has repeatedly produced above its OPEC+ quota as output from the expanded Tengiz field ramped up, a recurring point of friction with Saudi Arabia and other OPEC+ members trying to manage the market.
Which oil companies operate in Kazakhstan?
The oil company directory lists Chevron, ExxonMobil, Shell, Eni, KazMunayGas with producing operations in Kazakhstan. See the directory for who owns each company and which basins it works.
