According to reports in Aktyubinsk, local authorities are short on funds to liquidate abandoned wells.
The second-largest deposit on offer is Zhanatan, also in the Aktyubinsk region.
Zhanatan covers about 391 square kilometres and has an initial price of about 83 million tenge.
Three other oilfields that have been offered Biikzhal, South Kaskyrbulak and Pribrezhnoye are significantly smaller and are located in the Atyrau region.
Several blocks require additional exploration efforts to confirm the presence of hydrocarbons, the largest being Aralsky 4, which covers more than 3300 square kilometres in the dried seabed of the Aral Sea in the Aktyubinsk and Kyzylordinskaya regions.
Another large block, Aschibulak, also lies in the Aktyubinsk region. However, a small part of the block has been excluded as it hosts the Zhaksymay oilfield, which is being explored by KazInRuss Trading.
