Oil and gas production activity is unavoidably tied to the acquisition of land, and can lead to the contamination of soil, as well as a deterioration in the habitats of plants and animals. Each year, measures are taken under the Environmental Safety Program to remediate contaminated land.
Our longstanding working relationship with the UNDP/Global Environmental Facility (UNDP-GEF) and the Ministry of Natural Resources and Environment of the Russian Federation has enabled us to choose efficient remediation techniques for the natural restoration of biodiversity, including:
- the dredging of wetlands: a less impactful method for removing surface contamination that does not disturb native vegetation sprouts
- active adsorption of oil on flooded areas
- microbiological methods of soil bioremediation, using biological substances
- melioration and agricultural methods for oil stripping
- a two-tier system for protecting water courses during the remediation of coastal land
- a rotary cultivation system used in difficult-to-traverse swampy areas
LUKOIL-Komi has stepped up its remediation activity on disturbed land: work is being performed to eliminate three sludge pools that do not conform with current requirements in the Usinsk District, with a total area of seven hectares. Work is planned by 2019 to liquidate an additional 14 completed sludge pits at the Usinskoye and Vozeiskoye fields.
