Tengiz — oil from a mile-thick column, 13,000 feet down
The world's deepest supergiant field, and its $48 billion expansion
An unusually deep, unusually large reservoir:
Tengiz is Central Asia's largest oil producer and the world's deepest producing supergiant oilfield — its reservoir top sits roughly 13,000 feet (4,000 metres) underground, with an oil column measuring nearly a mile thick, the largest single-trap producing reservoir anywhere. It's operated by the Tengizchevroil joint venture: Chevron holds 50%, ExxonMobil 25%, Kazakhstan's state oil company KazMunayGas 20%, and LukArco (a Lukoil subsidiary) 5%. The field's oil and associated gas carry unusually high levels of hydrogen sulfide, a toxic and corrosive gas that requires specialised handling and reinjection systems most oilfields don't need.

The expansion:
A $45-48 billion expansion — the Future Growth Project and Wellhead Pressure Management Project (FGP-WPMP) — reached first oil in 2025 after years of pandemic-related delays, adding approximately 260,000 barrels a day of crude capacity and pushing total Tengiz output toward roughly 1 million barrels of oil equivalent per day once fully ramped up. It's among the largest single oil-project investments completed anywhere in the world in the mid-2020s.

One pipeline, one dependency
Kashagan, Karachaganak, and the CPC bottleneck
The other two fields:
Kashagan, an offshore Caspian field, is the second-largest contributor to the Caspian Pipeline Consortium crude blend after Tengiz, and is widely regarded as one of the most technically difficult and expensive oil developments ever attempted, given its combination of extreme cold, ice cover, and high-pressure, high-sulphur reservoir conditions. Karachaganak, a giant gas-condensate field, holds an estimated 60 trillion cubic feet of gas and 13 billion barrels of oil and condensate, operated by a joint venture including Eni, Shell, Chevron, and Lukoil.

The single-pipeline risk:
Nearly all of Kazakhstan's crude exports move through one route: the Caspian Pipeline Consortium line, running 939 miles (1,511 km) from Tengiz to the Russian Black Sea port of Novorossiysk, with roughly 90% of its throughput originating in Kazakhstan. That concentration has become a genuine strategic vulnerability since Russia's invasion of Ukraine — the pipeline has faced periodic disruptions, and ExxonMobil has publicly warned investors of the risk to its Kazakh cash flow if CPC exports are disrupted or curtailed. Kazakhstan has also persistently produced above its OPEC+ quota, a tension its Tengiz expansion is likely to deepen further.

Questions
Questions about Kazakh energy
Why does Kazakhstan route almost all of its oil exports through a pipeline that crosses Russia, given the obvious geopolitical risk?
Mostly geography and the timing of when the infrastructure was built. Kazakhstan is landlocked, and the Caspian Pipeline Consortium line was constructed in the 1990s specifically to give newly independent Kazakhstan and its emerging Tengiz field a reliable route to world oil markets via the Black Sea — at a time when Kazakhstan and Russia's relationship was considerably less fraught than it has become since 2022. Building an alternative route is neither quick nor cheap: pipelines take years to plan, permit, and construct, and Kazakhstan's alternative options — a rail link and the Baku-Tbilisi-Ceyhan pipeline via Azerbaijan and Georgia, or a route through China — carry much lower capacity or their own complications, so switching away from CPC at scale isn't something that can happen quickly even with strong political will. In effect, Kazakhstan is in a similar position to European countries that spent decades building energy relationships with Russia before 2022: the infrastructure reflects decisions made under very different geopolitical assumptions, and un-doing that dependency, if Kazakhstan wanted to, would require years of investment in new export capacity rather than a policy announcement. That's precisely why ExxonMobil has flagged the CPC's continued reliability as a live risk factor for investors, rather than treating it as a settled non-issue.
