Oil and gas basins of Kazakhstan



The oil and gas basins of Kazakhstan can be grouped into four revealed or prospective oil and gas provinces in the Republic of Kazakhstan. Exploration in those provinces in which oil and gas has already been extracted had, by 2010, led to the discovery of more than 200 oil, gas, oil-and-gas and condensate hydrocarbon accumulations. Of these, the Kashagan, the Tengiz and the Karachaganak fields can be considered giants.
