ELEMENTS OF THE MANAGEMENT CORPORATE SYSTEM DOCUMENTS

OBJECTIVES The Company’s policy related to improving the functional Federal Law No. 116-FZ “On the Industrial Safety reliability of pipeline is governed by legal requirements of Hazardous Production Facilities” dated July 21, and corporate standards 1997, Federal rules and regulations on industrial safety “Safety rules in and gas industry” (approved by Rostekhnadzor order No. 534 dated December 15, 2020); “Rules for the Safe Operation of In-Field Pipelines” (approved by Rostekhnadzor order No. 515 dated November 30, 2017); other federal regulations and rules on industrial safety

PRIORITIES/STANDARDS Our priority is to adopt an integrated approach to the safe Corporate regulations (STO LUKOIL 1.19.1-2012; operation of pipelines: inhibitor coating, the introduction of 1.19.2-2013 and 1.19.3-2013) -resistant pipes, timely diagnostics, and the prompt elimination of detected defects

INDICATORS The pipeline failure rate for oilfield pipelines, number of failures Resolution of the Network Group “Improvements to per 1 km, per year the Oilfield and Tubing Reliability” of PJSC LUKOIL (further, Network Group)

ASSESSMENT The principal source of expertise is the activities of LUKOIL’s Regulations on the Knowledge Management System of Improvement of the Oilfield Pipe and Tubing Reliability the Exploration and Production business segment Network Group, which forms part of the Corporate Knowledge (approved by the First Executive Vice President Ravil Management System Maganov on March 19, 2014)

RESPONSIBILITY The system covers all management levels, from senior The approved annual work plan of the Network Group management to specialized units at LUKOIL Group entities. as part of the Industrial Safety Program Responsible individuals in this area also include the experts and the head of the Network Group

TARGETED PROGRAMS, PROJECTS AND INITIATIVES Every Russian oil and gas producer has an investment program Annual and mid-term investment programs of “The renovation and technical re-equipment of PJSC LUKOIL facilities” The Integrated Program on the Improvement of Oilfield Pipeline Reliability, adopted by each entity of the Exploration and Production business segment 80 LUKOIL Group

Our goals • Increase of the share of pipelines The share of operating pipelines, with anti-corrosion coating: when including corrosion-resistant In Russia, LUKOIL operates a well- replacing corroded sections of pipes older than 20 years has developed field pipeline system that pipelines, we used such pipes been reduced.

We consistently last five years. in 2016). The inspection and carry out work to mitigate pipeline • The share of pipes with a longer monitoring of these pipes are more failure risks and have a well-run service life, as well as pipes made frequent, with the concurrent use of reliability management system for of non-corrosive materials, is being several methods of control during oilfield and mainline pipelines in place1. increased. one visit (for example, magnetic • The share of pipeline replacement inspection, automated diagnostic Our goal is the consistent maintenance in 2020 was 2.3 percent. The complexes, and other modern and stabilization of the system and the replacement volume and methods). reduction of pipeline accidents as per rate2 are determined based the best global practices. on the results of diagnostics, Thanks to the comprehensive examinations, and inspections measures taken, reliability indicators Continuous and targeted work to of their technical condition and improved in 2020 in the main oil improve pipeline reliability indicators subject to the following criteria: production areas — Siberia and is crucial for minimizing the risk any potentially hazardous sections the Perm Territory. The specific of accidents. At the same time, and preconditions for incidents, coefficient of pipeline failures3 in all other underlying causes, such as scheduled increase in product Russian entities continued to decline “human error” during construction, transfer volumes, and elimination in 2020 and stood at 0.062 cases maintenance, and repair activities of regulations by regulatory per 1 km of pipeline per year (0.081 performed by service organizations, authorities. in 2019). the integrity of other process equipment, etc., also influence the SAFETY SAFETY overall accident results.

1. The information in this section pertains only to the Russian entities of LUKOIL Group. 2. The rate of replacing rejected pipes is determined not only by the Company’s investment plans but also by the need to comply with statutory procedures and documentation. 3. A pipeline failure does not always entail a spill of oil, oil products or formation , or a gas leak. Pipeline failure means a failure of performance associated with a sudden total or partial shutdown of the pipeline due to depressurization of the pipeline itself or shut-off and control valves or a blockage of the pipeline. The calculation uses the total length of pipelines (oil pipelines, gas pipelines, and water pipelines). Sustainability Report for 2020 LUKOIL Group 81
