In 2007-2009 total emissionsat <strong>Gazprom</strong> <strong>Neft</strong> have increased due toan increased scope of operations.The bulk of the Company’s emissionsoccur in the oil and gas productionsector, whereas in the oil refiningsector they are on a decline. Loweremissions in refining can be attributedto environmental measures: renovationsof refining capacities, replacement ofburner units, equipping reservoirs withmodern emission lowering devices,introduction of an installation ensuringprecise and leak proof oil loading.PRODUCTION OFENVIRONMENTALLY-FRIENDLY FUELThe oil refining sector of the Companyworks consistently on improving theenvironmental friendliness of its fuels.The Omsk Refinery has come up witha development program designed toensure a complete transition to theproduction of environmentally-friendlyfuels by 2012. By the end of 2009 theplant completed modernization of theL-24/6 diesel fuel hydrotreater. Afterrestoration of the split-flow system, theinstallation can upgrade both summerand winter diesel fuel to Euro-3, 4, anddo it simultaneously. Construction ofan isomerization unit for light naphtha“Isomalk 2” plays an important role inthe further development of <strong>Gazprom</strong><strong>Neft</strong>. The main objective of this new unitis to increase production of gasolinesof Euro 4 and Euro 5 standards.Implementation of the isomerizationunit will enable processing of oil atdeeper levels and increase productionof gasolines. Isomerizate which“Isomalk-2” will produce is consideredthe most valuable component for highoctane fuel, free from olefine andaromatic hydrocarbons.UTILIZATION OF WATER RESOURCESThe Company’s enterprises seek toutilize water resources with maximumefficiency by injecting reservoir watersback into the wells to maintain thereservoir pressure during oil productionand by setting closed cooling cyclesin refining. In 2009 water consumptionfor the Company’s own needs was upby 4.4% compared to 2008 due to anincrease in oil production volumes andinjecting reservoir waters back into thewells in order to maintain the reservoirpressure.Water consumption grew slower thanthe Company’s operations. It was alsoslower than the last year’s growth rate(in 2008 water consumption for theCompany’s own needs was up by 15%,compared to 2007).WASTE TREATMENTThe Company strives to reduce wasteaccumulation and improve its wastetreatment practices. The largest shareof accumulated waste is representedby the drilling waste of hazard classIV (low hazard). In total, IV and Vclass (low hazard and essentiallynon-hazardous) waste accounts forover 90%. Drilling waste accumulatesduring the operations of oil producingand oil service (overall share of theseenterprises is over 90%). The mainmethod of drilling waste treatmentremains the placing of such waste indesignated storage areas. In 2009, 135sludge pits have been recultivated. Asa result of these measures, the risk ofabove-limit payments for prolongedstorage of drilling waste in the amountover 1 bln rubles was avoided.All industrial sectors of the Companywork on improving their waste treatmenttechnologies. The Omsk Refinery,for example, processes 100% ofaccumulated oils independently.New efficient technologies are beingintroduced in petroleum productdistribution, these include a mobiletreatment complex, designed to cleanthe inside of tanks from solid deposits.<strong>Gazprom</strong> <strong>Neft</strong> has also been successfulin implementing the pre-drillingprogram, when drilling of developmenttest wells with significant displacementof whole targets is done from alreadymade pads. So the geological structureand mining potential of the deposit areclarified in the zone of developmenttest pads without prior back filling. Thisenables the Company to spare the landwhere areal limits of soil sand havenot been confirmed. This technology116

The consolidated footingbraces pollutants and lowers therisk of them migrating elsewhere toa minimum. This solid drilling mix couldbe later used as a construction coatingfor firming up roads and laying down thebody of the pad.LAND CONTAMINATION CONTROLAND REMEDIATIONThe Company takes measures todecontaminate land and removeunauthorized waste storage spots. In2009, 219 ha of contaminated land wereremediated. To reduce the number ofareas with disturbed land the Companyplans to continue implementing pitlessdrilling.The Company’s enterprises useadvanced chemical biological agentsfor land remediation (like Fare Zyme),designed to destroy oil. They are basedon mineral, rather than biologicalcomponents, feeding the naturalflorula and facilitating land restoration.Biological remediation also involvesplanting area-specific grass andperennials.UTILIZATION OF ASSOCIATED GASIn the production sector a lot of workis being done on increasing the levelof associated gas utilization. The rateof associated gas (hereinafter – AG)utilization across the Company’s majorproduction enterprises remains at themedium level – 48.1% of recovered gaswas used in 2009 (in the tables belowyou can see the volumes of receivedand utilized AG in 2006-2009).Increasing the AG utilization rate isa priority set by the state, and in orderto contribute to reaching this goal, in2008 the Company adopted a MediumtermInvestment program for 2008-2010on AG utilization and more efficient use(hereinafter MTIP). Based on the MTIP<strong>Gazprom</strong> <strong>Neft</strong> has now developed anupdated Gas program. Actual financingof the MTIP projects in 2009 was 105%of what was planned. Implementationof the Gas program will allow theCompany to bring up the AG utilizationrate to 95% by 2012 at <strong>Gazprom</strong> <strong>Neft</strong>production assets.Automated AG control system will makemanagement in this area more efficient.Such system was designed in 2009.It will allow to quickly receive preciseinformation on production and usageof AG.117
