Waste Management

The Company’s industrial waste management system makes it possible to optimise waste flows, mitigate the environmental impact and reduce the economic cost of waste generation. The Company strives to maximise the possible use of large-tonnage waste in order to mitigate its environmental impact.

In order to meet this objective, Gazprom Neft began developing a corporate strategy for the utilisation of drilling waste in 2015. The goal of the strategy is to reduce the proportion of waste sent for disposal and to maximise its use in production processes as well as to employ the most environmentally and economically effective methods of waste utilisation taking into account the specifics of the regions where the Company operates. This work is to be completed in 2016.

In 2015, Gazprom Neft completed research and development work aimed at improving the efficient use of drilling waste. Company specialists have developed technology to obtain environmentally friendly soil from drill cuttings that can be used for the subsequent reclamation of sludge pits. A state environmental expert review has given a positive assessment to this technology.

WASTE DISPOSAL

The Moscow Oil Refinery is the first Russian oil refinery to complete the disposal of all its accumulated oily waste. The refinery fulfilled this requirement three years earlier than required. Over five years, the refinery utilised more than 180,000 tonnes of oily waste and eliminated the facilities at which it had been stored. As a result, the enterprise freed up 15 hectares of land and reclaimed contaminated soil.
