U.S. vs Global Oil Production — How America Compares to the World
The United States produces more oil than any other country but still imports millions of barrels per day.

Kazakhstan is Central Asia's largest oil producer and one of the most important emerging energy nations of the post-Soviet era. Since independence from the Soviet Union in 1991 Kazakhstan has developed three giant oil fields — Tengiz, Kashagan, and Karachaganak — that have attracted hundreds of billions of dollars in international investment and transformed the country into a significant global producer.
Kazakhstan's three giant fields tell the story of the country's oil industry. Tengiz in western Kazakhstan is a joint venture between Kazakhstan's national oil company KazMunayGas and Chevron — the American company has been the operator since 1993 in what was one of the first major Western oil investments in the former Soviet Union. A major expansion project — the Future Growth Project — has been adding significant new capacity.
Kashagan in the Kazakh sector of the Caspian Sea is one of the largest oil field discoveries in the past 40 years and one of the most technically difficult developments ever attempted. The field contains highly sour crude with extremely high hydrogen sulfide content that is toxic and corrosive, requiring specialized materials throughout the production chain. Kashagan was discovered in 2000, was supposed to begin production by 2005, but did not produce commercial volumes until 2016 — years late and massively over budget.
Kazakhstan's landlocked geography creates persistent export challenges — all oil must travel by pipeline through neighboring countries to reach global markets. The Caspian Pipeline Consortium carrying Tengiz crude to the Russian Black Sea port of Novorossiysk is the primary export route, creating a dependency on Russian infrastructure that complicated Kazakhstan's export options during the Ukraine conflict.

The Kashagan oil field in the Caspian Sea is one of the most technically challenging oil developments in history — the crude contains up to 25 percent hydrogen sulfide, a deadly toxic gas that requires the entire production system to be built from special corrosion-resistant materials at extraordinary cost, contributing to the project running over a decade behind schedule and tens of billions over budget.
Kazakhstan is landlocked — it has no access to any ocean — meaning all of its oil must travel by pipeline through neighboring countries to reach export markets. The Caspian Pipeline Consortium is the primary export route, creating a dependency on Russian infrastructure that was highlighted when the Ukraine conflict disrupted Novorossiysk loading operations in 2022.
Kazakhstan's oil industry attracted some of the largest per-capita foreign direct investment of any country in the world during the 1990s and 2000s as Western oil companies competed for access to its giant fields — making it one of the most dramatic examples of post-Soviet economic transformation driven by natural resources.
Kazakhstan produces approximately 1.9 million barrels of crude oil per day primarily from the three giant fields of Tengiz, Kashagan, and Karachaganak in the western part of the country. Production has been growing as expansion projects at Tengiz add new capacity and Kashagan continues to ramp up.
Kashagan is one of the most technically challenging oil fields ever developed. The crude contains extremely high levels of hydrogen sulfide — a toxic and highly corrosive gas — that requires specialized materials throughout the entire production system. The remote Caspian Sea location, extreme temperatures, and the complexity of managing sour crude at scale all contributed to massive delays and cost overruns that pushed commercial production from the originally planned 2005 start to 2016.
Kazakhstan relies primarily on the Caspian Pipeline Consortium pipeline which carries crude from the Tengiz field across Kazakhstan and Russia to the Black Sea port of Novorossiysk for tanker loading. A secondary route goes through the Baku-Tbilisi-Ceyhan pipeline via Azerbaijan and Georgia. Both routes pass through other countries creating geopolitical vulnerability — the Ukraine conflict disrupted Novorossiysk loading operations temporarily in 2022.
