Clean Water Subprogram

Management Approach DMA
The key wastewater clearing measures include:
- in-process control over the quality of wastewater discharges and the condition of the impacted bodies of water;
- commissioning of new and/or revamping of existing water treatment facilities;
- identification of defects and a major overhaul of pipelines and their inhibitory protection;
- construction of initial water discharge and utilization systems;
- revision of pipeline passages through bodies of water;
- treatment of contaminated groundwater from drainage systems.
Offshore facilities follow the “zero discharge” principle that rules out any contamination and involved in-process environmental monitoring.
Clean Water Subprogram: Water discharge
The Environmental Safety Program has put a stop to discharges of contaminated (or insufficiently treated) wastewater into bodies of water across all business sectors, other than Oil and Gas Production in Russia.
Compared to 2014 levels, discharges of contaminated (insufficiently treated or untreated) wastewater by LUKOIL Group entities has decreased, mainly due to a complete cancellation of wastewater discharges by OOO LUKOIL-Volgogradenergo into bodies of water. Water treatment facilities were constructed at Pyakyakhinskoye, a field operated by OOO LUKOIL-West Siberia in the Yamal-Nenets Autonomous Area.
The accounting policy has been adjusted with respect to the discharge of wastewater: land disposal of wastewater has been excluded from the record in accordance with changes in Russian legislation. Nevertheless, the Company continues to tackle the issue of land disposal of contaminated wastewater, in particular, discharges of salt-wastewater into a sludge pit at Astrakhan SGP-110, operated by OOO LUKOIL-Astrakhanenergo. A project is underway to prevent wastewater filtration into subsurface horizons by waterproofing the bottom of the sludge pit with a polymer film.

Clean Water Subprogram: water withdrawal
Management approaches DMA
The key fresh water consumption reduction measures include:
- monitoring fresh water consumption;
- commissioning new and/or revamping the existing reverse water supply and recycling facilities.
The Company’s entities also operate in arid regions, where fresh water is scarce (Stavropol and Krasnodar Territories, Saratov, and Volgograd Regions). The issue is primarily addressed by putting water supply and recycling systems into service and ensuring the most beneficial use of the water withdrawn, including stratal water. As part of its social partnership with different Russian regions, the Company has ongoing projects to supply their residents with drinking water.
Most of the water consumption of the LUKOIL Group (i.e. over 90%) is used to satisfy production needs, of which, about 70% is used to meet demand from power and heat generation facilities, and about 20% goes to business units to maintain formation pressure within mineral extraction blocks.
LUKOIL Group entities also have their water intake facilities replenished by enterprises located within proximity of the Company’s sites, however, their share in the total water withdrawal has been declining.
Power engineering companies use water to produce steam and cool down CHP equipment. The specific water withdrawal in the business sector has been reduced due to the decommissioning of obsolete equipment.
In November 2016, at its Yarega field, OOO LUKOIL-Komi commissioned VPU-700, a water treatment unit (capacity: 700 cubic meters per hour) to treat stratal water and produce steam that is subsequently injected in pay beds during the production of high-viscosity oil. With this facility in operation, the company will cut back on its water intake from the reservoir and use stratal water more efficiently.
A reduction in specific water withdrawal in the Petrochemicals sector was due to expansion of production.
|Water consumption, including:||525.0||526.8||522.2|
|surface bodies of water||314.0||305.9||297.4|
|subsurface bodies of water||81.0||78.7||77.1|
|other sources (central water supply networks, etc.)||130.0||142.2||147.6|
|Water consumption for own needs of the LUKOIL Group entities, including:||402.7||413.1||415.9|
|business needs (excluding consumption to maintain formation pressure)||303.9||304.8||307.4|
|formation pressure maintenance||76.5||79.2||76.4|
|Oil and Gas Production in Russia, cubic meters/ton of reference fuel of produced hydrocarbons||1.0||1.0||1.0|
|Oil Refining in Russia, cubic meters/tons of refined oil||0.4||0.5||0.6|
|Petrochemicals, kg/tons of processed raw stock||21.2 Affected by downtime caused by the OOO Stavrolen accident.||12.8||6.2|
|Product Marketing and Distribution in Russia, cubic meters/tons of sold petroleum products||0.04||0.047||0.055|
|Midstream, cubic meters/tons of transported oil and petroleum products||0.04||0.045||0.039|
|Power engineering, cubic meters/TRF (tons of reference fuel) of consumed fuel||47.8||40.7||40.1|
Fresh water consumption across the business sectors remains low. New production facilities are fitted out with reverse water supply and recycling systems. Compared to 2014, in 2016, water circulation in the said systems went up 30% (or by 768 million cubic meters), which results in substantial savings of natural water resources.
