University of Tyumen scientists have developed a bioremediation method for soil polluted with mineralized formation water. Unlike its counterparts, the new method is effective in the climate of West Siberia. The method has passed expert review and has a patent pending.


During the process of liquid hydrocarbons extraction, mineralized formation water comes up to the surface and causes soil pollution. The time needed to neutralize the polluted soil is halved when done using the UT method.

UT scientists’ method involves planting sea aster (Aster tripolium) for the treatment of polluted areas, as saline lands are its natural habitat and it amasses salt in its tissues as it grows.

Speaking of the environmental threat, specialists explained that during liquid hydrocarbons extraction, crude oil (about 10%) and mineralized formation water (about 90%) comes up to the surface. After the separation process, crude oil is sent to refineries, while the aggressive liquid is injected back into the reservoir.

According to the scientists, one seed per square centimetre of polluted soil is enough for successful remediation.

The sustainable management of West Siberian natural resources is one of UT’s top priorities, along with the development of technological solutions for recycling oil industry waste.
