Oil and Gas
Major actors in the oil and gas industry of Kazakhstan
The Tengiz oil field was discovered in 1979. This oil deposit is 19 km long and 21 km wide, the deepest among all the known developed super-giant oilfields. This oil field had to be developed under very harsh conditions (considerable depth, abnormally high strata pressure, high temperature, high content of hydrogen sulphide, acid components, etc.) The discovery and assessment of Tengiz doubled Kazakhstan’s oil reserves. Its size and favourable geographic and economic location, including closeness to main pipelines, power transfer lines, railway and a large industrial center, made it a priority for the national industrial strategy. Commercial oil production in Tengiz started in 1991.
