Pavlodar Oil Chemistry Refinery LLP, operating under the Kazakh abbreviation PNHZ (Павлодар Нефтехимический Завод), is the largest oil refining and petroleum products enterprise in the northeast of Kazakhstan and one of only three commercial oil refineries in the Republic. The company operates as a Limited Liability Partnership (LLP / ТОО) under Kazakhstani corporate law. It is a wholly owned subsidiary within the KazMunayGas (KMG) group, with 100% of its participatory shares held by National Company KazMunayGas JSC — the vertically integrated national oil company of the Republic of Kazakhstan, itself majority-owned by the sovereign wealth fund Samruk-Kazyna JSC.
Corporate Parentage and Ownership Chain
POCR LLP sits within a clearly defined state-controlled ownership chain. The direct shareholder is KazMunayGas Refining and Marketing JSC (KMG R&M), a downstream subsidiary of KMG responsible for refining operations across Kazakhstan's three main facilities. KMG R&M is itself fully consolidated under National Company KazMunayGas JSC (listed on the Astana International Exchange and London Stock Exchange), which in turn is majority-controlled by the Samruk-Kazyna National Welfare Fund JSC — the Republic of Kazakhstan's state asset-holding vehicle.
This ownership structure has remained stable since the early 2000s, when the plant transitioned from a complex ownership history involving private creditors — including a period in which Mangistaumunaigas held a stake taken on account of debts — before the state consolidated full control. The plant has been under 100% KMG group ownership since that consolidation, though as of March 2025 Kazakhstan's competition regulator, the Agency for Protection and Development of Competition (AZRC), has formally proposed the partial privatisation of POCR LLP, recommending a sale of up to 50% of the state's stake to a private investor — citing the Shymkent refinery's 50/50 KMG–CNPC structure as an operational benchmark.
Business Activity and Industrial Role
The company's core activity is the primary and secondary processing of crude oil sourced predominantly from West Siberian oil fields, delivered via pipeline from Russia — a legacy of the refinery's Soviet-era design orientation. POCR produces a broad slate of petroleum products including motor gasolines (various octane grades), diesel fuel, jet fuel (Jet A international standard), liquefied petroleum gas (LPG), fuel oil (mazut), vacuum gas oil (VGO), commercial sulfur, bitumen (construction, road, and roofing grades), and petroleum coke.
POCR is not involved in upstream crude production or exploration. Its commercial role is confined to refining, processing, and dispatch of petroleum products for domestic consumption in Kazakhstan's northern and northeastern regions, with some export potential. The company operates within the KMG group's vertically integrated downstream segment and does not independently market crude oil or have trading operations outside of product dispatch.
Modernisation and Strategic Positioning
POCR underwent a major modernisation programme completed in December 2017, representing an investment of approximately $1.2 billion. This programme commissioned two new process complexes — an Isomerization and Naphtha Splitter unit and a Complex of Sulfur Recovery Units — and revamped existing primary distillation and advanced processing facilities, enabling the production of Euro-4 (K4) quality motor fuels in compliance with Technical Regulation TR CU 013/2011. The upgrade also included a Delayed Coking Unit revamp and commissioning of 12 new utilities and offsite (U&O) facilities.
The company's current strategic priority, as stated on its corporate website, is to advance to Euro-5 (K5) fuel quality production across both gasoline and diesel, introduce Jet A aviation fuel as a new product line, and extend the refinery's operational campaign to a three-year inter-repair cycle. These objectives align directly with Kazakhstan's national 2025–2040 oil refining development concept, under which POCR is one of the three existing refineries earmarked for capacity expansion in Phase 1 of the programme.
Environmental Commitments
POCR LLP maintains a formal environmental management programme aligned with Kazakhstani environmental legislation. Environmental protection expenditure in 2025 amounted to 903 million KZT. The company's stated environmental strategy focuses on reducing operational emissions and pollutant loads, improving energy efficiency across process units, reducing greenhouse gas emissions, and strengthening environmental competency and employee engagement across its workforce.
Workforce and Scale
POCR LLP is an industrial-scale operating entity rather than a holding company, with the operating workforce concentrated at its single site in the city of Pavlodar, Pavlodar Oblast. The company functions as an integrated refining operation with a Central Refinery Laboratory (CRL), extensive utilities infrastructure (water supply, sewerage, tank farms, rail and road loading/unloading racks), and supporting social infrastructure for employees.
