Waste Management

Ensure sustainable consumption and production patterns.

Waste management in companies of the group is one of the most important environmental aspects. As hydrocarbon production and processing industry is distinguished by the high level of formation of various types of wastes, including essential volumes of hazardous wastes, the KMG controls the processes leading to formation of certain types of waste, volumes, disposal methods and ways of transportation.

First of all, the companies of the group try to meet the requirements of the legislation in the area of waste management. For this purpose Waste Management Programs are developed and implemented in the companies of the Group. Significant financial resources are allocated for solution of problems, related to wastes generation and land pollution at production facilities.

Some companies are processing significant amounts of historical wastes and contaminated land on a voluntary basis. In recent years, KMG has been keeping records of waste generated throughout the contract area, including all wastes generated by contractors. KMG also monitors its contractors to ensure their activity is complied with the requirements for safe transportation, landfilling and disposal of waste. New approaches and technologies in waste management are regularly reviewed to be further implemented in production facilities.

Volume of hazardous wastes for 2017 by management kinds, thousand ton

Dynamics of wastes generation by areas, thousand ton

* The sharp decrease in the volume of waste generation in 2017 in the direction of the Service is due to the fact that in that year the waste generated as a result of the activities of LLP Oil Services Company was accounted for as waste generated in the contract area of the MMG JSC, as LLP Oil Services Company performs drilling operations only for MMG.

Volume of generated wastes in 2017 is 336.3 thousand ton (more on 10.2 % than in 2016), among them 323.58 thousand ton were classified as “dangerous”, and 12,7 thousand ton as “unhazardous”. Most part of hazardous waste – 57.4 % are drill mud (drill cuttings and waste drilling mud).

More 80 % of all generated wastes is transferred for processing to specialized companies under a contract. Other significant ways of waste management are: reuse, recovery, combustion and placement at disposal site.

Drill mud generation

Extracting companies of the KMG generated 185.829 thousand ton of drill mud (on 22.8 % more than in 2016) in 2017, including: 50.49 thousand ton – waste drilling mud; 135,339 thousand ton of drilling cuttings. Increase of volume of drill mud is associated with increase in number of drilled wells in 2017 compared to the previous year (for example, wells were drilled at Satpayev block and 27 exploratory wells in EMG*). All drill mud of extracting companies of the KMG group is transferred to specialized organizations for disposal. Methods of further waste disposal by these companies: inertisation, thermal method, chemical method, biological remediation and dumping at special disposal sites.

Extracting companies of the KMG from specified perimeter do not perform drilling operations, using non-aqueous drill mud (water-based only).

Main storage facilities (and terminal point) of waste waters of KMG enterprises are various specialized storage facilities: storage ponds, evaporation fields and filtration fields. These facilities are technical facilities, intended for natural waste water purification and prevention of environmental pollution. All drains of the enterprises undergo mechanical and biological purification before entering storage facilities. Enterprises, which do not have own storage facilities, transmit drains to special companies for cleaning and disposal.

There is no information on use of waste water of enterprises from other companies. Within the Group of companies there is a transfer of waste waters of any companies to treatment facilities of others. For example, KazGPZ partially transfers its drains to OMG for recovery.

There is no unscheduled discharge in the Group of companies KMG. All volumes and quality of discharged waters are subject to standartization.

Reservoirs, affected by water disposal and drain

Group of companies KMG do not discharge waste waters into natural water bodies. All discharges from enterprises are produced to specialized objects (storage facilities, evaporation ponds, filtration fields) after appropriate treatment. Use of surface water bodies for water disposal is prohibited according to the Article 89 of the Water Code of the Republic of Kazakhstan.

The group companies, operating at the sea, observe “zero discharge” principle – all waste and drains are transported ashore for disposal. Water disposal within the state conservation area in the north part of the Caspian Sea is prohibited by the Article 262 of the Environmental Code of the Republic of Kazakhstan.

Volume and recovery of local waters

Extracting companies of the KMG extracted 124.416 mln m3 of associated local water during oil extraction in 2017 (on 1.2 mln m3 more than in 2016 and on 2.4 mln m3 more than in 2015). Most part of this water (123.348 mln m3 or 99 %) was injected into the reservoir to maintain reservoir pressure. Reinjection of associated local water is method of recovery and effective method of oil recovery intensification. Remaining 1 % of produced local water is injected into absorption wells (as maintenance of reservoir pressure is not required on the deposit, where it is extracted together with oil). Water-oil emulsion is extracted to the surface during oil extraction, which is subsequently divided into water and oil by gravitational method. Such water is injected into reservoir after additional treatment.

Injection of local waters for maintenance of reservoir pressure during the development of raw hydrocarbons is object of Special Water Use according to the Article 66 of the Water Code of the Republic of Kazakhstan.

Benzol, lead and sulfur content in fuel

In accordance with the State Program of Industrial and Innovative Development of the Republic of Kazakhstan, modernization and reconstruction projects are implementing on three refineries in the Republic, which will allow producing a fuel of new class K4, K5. Gasoline, produced by Kazakhstani refineries, has improved environmental properties, and supplied to all regions of Kazakhstan, and highly appreciated by consumers. Products, produced by the refinery, comply with the requirements of Technical Regulation TR TS 013/2011 “On Requirements for Petrol and Aviation fuel, Diesel and Marine Fuels, Jet Fuel and fuel oil”, where fuel requirements are specified for the purpose of protection of human life and health, property, protection environment, preventing misleading actions for consumers about its purpose, safety and energy efficiency.

Hydrotreating process is an integral part of technological process, ensures reduction of undesirable components S/N/O/, metal compounds, etc. Use of modern production technologies ensures reduction of sulfur and benzole levels and compliance with the requirements of emission classes K4/K5. Metal-containing additives are not used (prohibited by technical regulations (TR TS 013/2011).

To ensure the proper quality of fuel, continuous monitoring is carried out throughout the entire chain supply of oil products: from the plant to bulk plants and gas stations.

Gasoline

Gasoline shall be chemical-resistant and not cause corrosion. Corrosion activity of gasolines and their combustion products depends on content of total and mercaptan sulfur, acidity, content of water-soluble acids and alkalis, presence of water.

Content of lead compounds in gasoline is the most important among environmental indicators of gasoline. In this regard, Pavlodar refinery LLP completely refused of use of ethyl liquid. Highly toxic lead compounds are almost absent in gasolines.

Diesel fuel

Diesel fuels are produced mainly by mixing of directly distilled component from crude oil distillation plant with diesel fuel, which has undergone hydro treatment for reduction of content of sulphurous, nitrogenous, oxygen-containing, organometallic compounds.

Fuel natural gas

The basic component of natural gas is methane (CH4) – up to 98 %. Heavier hydrocarbons can be included into the composition of natural gas – methane homologs: ethane (C2H6), propane (C3H8), butane (C4H10), and other non-hydrocarbon substances: hydrogen (H2), hydrogen sulfide (H2S), carbon dioxide (CO2), nitrogen (N2), helium (He).

Natural gas has no color and odor. In order to detect a leakage by smell, a small amount of substances with strong unpleasant odor (so-called odorants) is added to gas. Ethyl mercaptan is used as an odorant.
