It was established that the sorption processes and migration of Kumkol oil in various types of soils of South Kazakhstan oblast (SKO) depend on their physical and chemical properties and temperature. All types of soils, except for desert sand and red-ferralitic clays have a high sorption capacity for the volume of Kumkol oil. Compact placic horizons of takyr and gray-brown soils obstruct the filtration of oil on the profile, and the desert-sandy soil and red-ferralitic clays, due to the large volume of their total porosity have the ability to pass the oil into deeper layers of the horizon. At low temperatures, the depth of migration of oil depends on the porosity of the soil, excess of oil on the surface of the soil forms a thick bitumic crust, which negatively affects the water and air regime of soil.
