Construction of islands from metal structures has been recommended for the fields. The operator is planning to complete all these works before 2019,” Nurabayev said.
Based on Kazakhstan C1+C2 evaluation methods the increase in the proved recoverable reserves made 98.6 million tons of oil: 67.6 million tons of oil in Kalamkas-sea and 31 million tons of oil in Khazar field.
