Environmental protection

One of our company’s core values is to “Protect Tomorrow Today.”  At Exxon Neftegas Limited, environmental protection and mitigating our environmental impact are key priorities across all project stages.  The Sakhalin-1 Project operations meet the most stringent Russian nature conservation laws, international standards, and ExxonMobil corporate policies.

To ensure the Project’s environmental safety, we work with leading Russian and international research institutions like the National Research Center of Marine Biology, the Pacific Oceanography Institute of the Far East Branch of the Russian Academy of Sciences, Moscow State University, Oregon State University, the Institute of Ecology and Evolution of the Russian Academy of Sciences, and others.

We heavily invest in research about local ecosystems and in the development of effective environmental protection solutions.  Sakhalin-1 Project facilities and pipelines are earthquake resistant, our tankers can withstand the harshest winter conditions, and we reinject water and surplus gas to maintain pressure in our oil reservoirs. These examples highlight our focus on mitigating our environmental impact.

We constantly monitor the environment throughout facility planning and operating phases.  We restore and maintain pipeline routes, monitor the seawater, drinking water and atmospheric air quality, marine biota and bottom sediments, along with the soil, plants and fauna in our areas of operation.  Exxon Neftegas Limited environmentalists monitor these and other indicators on a weekly, monthly, quarterly, and annual basis in accordance with our environmental monitoring program

The Sakhalin-1 Project began more than 20 years ago and long-term data and observations show that our adherence to high safety standards, thorough planning of facility designs and the application of advanced technologies, coupled with scientific research, have ensured responsible environmental protection.

Spill Prevention

Oil spill response preparedness is a major element to ensuring industrial safety and environmental protection. The Joint Corporate Oil Spill Prevention and Response Plan is applied across all Sakhalin-1 Project facilities. Regular training and drills for company employees and contractors are conducted  to maintain a high level of response preparedness in case of an emergency. Over 400 OSR training events of various scales were conducted throughout 2018. Specially trained responders are always prepared. In addition to training events, we organize several annual full-scale drills focusing on various accident scenarios. Skills in oil spill response, fire safety, first aid, personnel mustering and evacuation are tested during these drills.  Two such major drills were held in 2018.

Waste Management

One of the critical aspects of our environmental protection efforts involves a well-organized waste management system based on international waste standards of the Exxon Mobil Corporation and Russian laws.  It aims to ensure cost-effective and environmentally friendly waste management across the Sakhalin-1 Project.  The Exxon Neftegas Limited waste management strategy covers:

  • Minimization of waste generation
  • Waste recycling and reuse
  • Use of best available technology in waste decontamination and burial
  • Waste disposal at dedicated landfills

To minimize waste, Exxon Neftegas Limited annually implements a number of initiatives and activities aimed at using low-waste and resource-saving technologies.  Energy-saving LED lamps and an electronic document workflow that replaced our paper-based workflow are two initiatives that have proven highly effective in decreasing our waste generation.

Unusable sediments, surplus water and gas, and sewage account for the bulk of all waste generated at Sakhalin-1 Project facilities.  Virtually all of these  waste products are reinjected into subsoil reservoirs for pressure maintenance. This waste management approach has proven to be the most environmentally safe.

Industrial and domestic waste account for the rest of the waste generated.  Our main focus for waste collection, segregation and mechanical processing is to identify the waste generation sources and separate the waste that can be reused in the production process or recycled as secondary raw materials.  The percentage of industrial and domestic waste sent for recycling and reuse in 2019 increased to 76.5% from 68.7% in 2018.

This was achieved by adhering to strategic planning, a centralized waste management and recycling program, an analysis of key performance indicators, comparisons with the Industry’s best practices and constant work method improvements.
