At present, the problem of oil pollution of soils in our country is little solved, and work on cleaning oil pollution with the help of microorganisms is not coordinated, their scientific and technological level is low. Thus, the problem of contamination of soils with oil and petroleum products is more acute than ever. There are mechanical, thermal and physico-chemical methods of cleaning soils from oil pollution, they are effective only at a certain level of pollution. Typically, at least 1% of the oil in the soil is often associated with additional contamination and provides complete purification. Contamination of soils with oil and petroleum products is one of the most difficult problems of ecology and environmental protection. Nowadays, technologies for bioremediation of oil-contaminated areas are being successfully developed, but their level does not help to cope with the problem locally, quickly and economically. The article is devoted to the development of an effective method of reclamation of areas involved in oil and gas production. In particular, those areas that are allocated for the placement of pits and are one of the most polluted at the end of mining. The solution to the problem is achieved through the use of a modified pit design, as well as the use of sorbent from the wastewater treatment plants. Reduction of soil contamination on the site allows further use of the oil sludge pit, including agricultural activities. The developed method can be used in any drilling operations, as well as in activities involving the reclamation of areas exposed to pollution due to oil spills, as well as those soils that have degraded due to the migration of pollutants associated with the process of drilling
