Annotation:
The article presents the results of research and field work that provide the possibility of a long-term conservation of open wellbores during the construction of offshore wells on the Arctic shelf. The technical requirements for a long-term conservation of offshore wells with open wellbores are substantiated. Compositions, technology for the preparation and use of conservation special liquids (CSL) for a period of up to a year when drilling in the Arctic conditions have been developed. The conducted field tests confirmed the high geological and technological efficiency of CSL use. The "Instructions for the preparation and use of conservation special liquid for offshore wells (CSL)" have been approved.
