Impact of Oil Pollution on the Depth and Cryogenic Structure of the Seasonally Frozen Layer at Samotlor Field, West Siberia

摘要

This paper presents the results of the field study of oil pollution at Samotlor Field in West Siberia in summer and winter periods. It shows that light hydrocarbons of oil may remain in the seasonally frozen layer for a long period of time. The impact of oil pollution on the depth and the cryogenic structure of the seasonally frozen layer was established.
