Our work 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 barns 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 barn 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 barn, 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 in the process of drilling.
