Our involvement toward Environment

The Promotion of Environmental Conservation

In accordance with our "Health, Safety, and Environmental Policy" and the "ENEOS Group Environmental Policy," we adhere to legislation concerning the environment, and promote environmental conservation through various business activities.

Adherence to Environmental Laws and Regulations and Disclosure of Environmental Information

We endeavor to adhere to environmental laws, regulations, ordinances, and so forth, and proactively disclose environmental information concerning our oil and natural gas exploration and production business by publishing it in our annual ESG Data Book.

Nakajo Field Office receives Forest Conservation Project Awards

Nakajo Field Office had received the award from the Niigata Prefecture Forest Conservation Association in 2019 to their voluntary works for the contribution to its Forest Conservation Project. Nakajo Field Office has been promoting the tree planting program in Nakajo area as a volunteer scheme since 2011.

The Environmental Management System in Malaysia Receives an Award

The level of the environmental management system of our Miri office was commended through environmental conservation activities promoted by the Sarawak State Government in Malaysia, and in March of 2017, the system was awarded the GOLD AWARD under the category of Large Enterprise Industries – Oil & Gas for the 7th Sarawak Chief Minister's Environmental Award, 2015/2016. Moving forward as well, we will continue to put efforts into environmental conservation activities in all countries where we conduct business, including Malaysia.

Climate Change Mitigation

CO2 produced from combustion process and methane gas released from production facilities are the typical greenhouse gases associated with oil and gas exploration and production operations. At our main oil and gas fields, such as the Rang Dong oil field in Vietnam and the Mubarraz oil field in the Middle East, we have curtailed these greenhouse gas emissions drastically introducing the special program.

Rang Dong Oil field (Vietnam)

Initially associated gas with crude oil production had been flared at production site however in September, 2001 new project had launched to export the gas to electric power station for the fuel source in Vietnam. This program had been applied for the Clean Development Mechanism (CDM) Executive Board, in line with the Kyoto Protocol, to register this program as a CDM related to greenhouse gas emission trade, and the application was approved in February of 2006 (The associated gas is currently injected into the oil reservoir and not exported to the power station). In addition, we have installed systems for the generation of solar power and wind power, which are clean energy sources, in offshore facilities at Rang Dong oil field, and these systems provide a portion of the energy.

Abu Dhabi Oil Co Ltd, (the United Arab Emirates)

Abu Dhabi Oil Co Ltd, of which JX Nippon is a shareholder, operates offshore facilities at the Mubarraz oil field in the UAE. It injects associated sour gas back into the oil reservoirs at depths of around 3,000 meters below sea level, using a high-pressure compressor. This operation has greatly reduced CO2 emissions into the atmosphere and also enhances the reservoirs' crude oil recovery.

Increasing Crude Oil Production and Decreasing CO2 through CO2-EOR (Enhanced Oil Recovery)

CO2-EOR refers to injecting CO2 (carbon dioxide) into the depleted oil reservoir improving the oil recovery and storing the injected CO2 underground securely thus it will control the CO2 emission in the air. We are participating in CO2-EOR projects that utilize this cutting edge technology in order to decrease the emission of CO2, which is a cause of global warming.

CO2-EOR project using post-combustion carbon-capture system at coal-fueled power plant in US

In 2014 JX Nippon launched a project in the US to build and operate a commercial-scale carbon-capture system that collects CO2 from the flue gas of a coal-fired power plant. The captured CO2 can then be injected into an oil field to increase oil recovery and CO2 will be stored in the oil reservoir instead of the emission to the air.

One of the world's largest post-combustion carbon capture facilities has been constructed at the WA Parish power plant southwest of Houston, Texas. The captured CO2 is compressed and piped through a 130-kilometer pipeline to the West Ranch oil field, where it is expected to boost the field's dwindling output. This is a revolutionary project set to revitalize legacy oil fields while at the same time reducing the industry's carbon footprint. The project is expected to capture approximately 1.6 million tons of CO2 annually that would be otherwise released to the atmosphere.
