The pollution of environment by oil spills in the process of extraction, refining and transporting of oil is an important ecological problem of oil industry. Composition and properties of the oil sludge and oilcontaminated soil taken from the area of Zhetybai – Uzen – Atyrau pipeline failure have been investigated aiming at development of oil waste utilization methods. The offered thermal method of organic fraction extraction allows to decrease the organic fraction content by 15–20 %. It is shown that the recovered oil may be used for the bitumen production, and the solid residue – as a component of cold asphalt concrete.
