Gazprom Neft reclaims disturbed and contaminated land and sludge pits by introducing advanced technologies for pipeline monitoring and diagnostics and restoring soil taking into account the soil and climatic conditions of the regions.

As part of the ‘Clean Territory’ project, the Company conducts diagnostics and monitors corrosion in an effort to reduce pipeline failure rates and the area of contaminated land. One of the focuses of the project is the reclamation of polluted “historical heritage” land.

Gazprom Neft and Tyumen State University launched cooperation in conducting chemical and analytical quality control of the environmental restoration work being carried out by Gazprom Neft. Independent laboratories at Tyumen State University will analyse soil samples in reclaimed areas of oil contaminated lands, drilling waste, oily waste, and products generated from their utilization. Independent control is a proactive measure that allows for promptly identifying and correcting deviations when performing environmental restoration work.

In 2017, the Company continued to replicate the ‘Green Seismics’ technology at its enterprises, which saves trees from being cutting down during seismic operations. The conventional approach requires creating wide clearings that are needed for heavy all-terrain vehicles to pass through. Thanks to cable-free recording equipment, which can be installed using light technology, ‘Green Seismics’ allows for significantly narrowing the clearings or not making them at all. The technology is already being utilized at Gazpromneft-Noyabrskneftegaz, Gazpromneft-Khantos, Slavneft-Megionneftegaz, and Gazpromneft-Vostok.

New reclamation methods

In 2017, Gazpromneft-Noyabrskneftegaz conducted the pilot testing of recultivation technologies for saline lands.

Washing the soil layer with water and using agronomic and biological methods of reclamation revealed it was possible to accelerate the adaptation and purification of soils. Based on the testing results, the technology will be introduced at the Company’s facilities.
