Oil and gas resource production volumes in Russian fields are more confined to the development of areas discovered in the 70s-80s. According to their operation and development level, a depletion of reserves and a decrease in reservoir pressure are observed. The long time for development contributes to the complication of well construction conditions in these fields, especially in the matter of ensuring the reliability of separation of discovered reservoirs. The analysis of drilling and completion materials for fields in North Siberia and the Artic region showed that the absorption value of cement slurries during well attachment has increased, as well as the presence of inter-reservoir flows.
