Innovation in the Field of Environmental Protection
In 2014, Gazprom Neft-Noyabrskneftegas launched an innovative facility for the thermal destruction of oil sludge at the Vyngapurovskoye field. The sludge can now be processed without waste.
The sludge is decomposed at a high temperature in an oxygen-free environment into its component parts: oil, water, and mechanical impurities (clay, sand, and metal oxides). The oil produced during the process is completely ready for transport and sale. The resulting water can be used without any additional purification. The mechanical impurities extracted include cleaned subsoil which can be used as a building material in road construction or as backfill in the foundations of well pads. Associated petroleum gas (APG), which is separated during sludge processing, is used to power the facility. Processing is carried out without releasing the products of combustion into the atmosphere.
