Oil and gas basins of Kazakhstan

The oil & gas basins of Kazakhstan can be grouped into four revealed or prospective oil & 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.
Oil & gas basins of Kazakhstan.
Kazakhstan has a share in four oil & gas provinces:
1. The "Pre-Caspian Basin" lies in the western part of the country, behind the Mugodzhary mountains. The geology of this province is made up of Paleozoic sediments covering a Proterozoic basement.
2. The "Mangistau-Usturt Basin" lies in the Mangistau and Aktyubinsk areas of Kazakhstan.
3. The "Central Kazakhstan Basin" lies in the eastern and southern areas of Kazakhstan.
4. The "Western Siberian Basin" is in the northern and northeastern region of Kazakhstan, north of the Kokshetauskikh mountains. The geology is of a platform type, with a Mesozoic cover overlying a Paleozoic basement.
The basins are located in six provinces of Kazakhstan: Aktobe, Atyrau, West Kazakhstan, Karaganda, Kyzylorda and Mangystau provinces.
