Determination of Material Issues


In order to further define the key areas for our ESG practices and information disclosure and make this report more pertinent to stakeholders’ concerns, CNOOC Limited has identified issues that stakeholders are potentially concerned with and determined their importance in accordance with the requirements of the Environmental, Social and Governance Reporting Guide issued by HKEx. Through this exercise, we finalized the extent and scope of issue disclosure for a more accurate and comprehensive disclosure of ESG information.


To rank issues by importance, we conducted questionnaires to learn more about stakeholders’ views about the Company’s ESG work, and asked open-ended questions to understand their expectations and suggestions to make specific responses and improvements in the future.


Determination process of ESG issues



Step 1:


Identifying relevant issues

Material issues were identified by the Company’s independent third-party advisor. A total of 19 ESG issues related to economy, environment, labor, human rights, and other social affairs were gathered from a large number of data sources, including the HKEx ESG Reporting Guide, GRI Standards, stakeholders’ opinions, corporate policies, management strategies, industry benchmarks, ESG rating system analysis, and internal publications and media reports.

Step 2:


Assessing the degree of concern

Seven groups of stakeholders were surveyed by our independent adviser. They were invited to assess and rank the importance of each issue based on their own understandings. In total, 204 effective questionnaires were collected.

Step 3:


Analyzing the impact on our operations

We asked senior managers at CNOOC Limited for their opinions on the materiality of identified issues from the perspective of company operations.

Energy Supply


CNOOC Limited is committed to promoting sustainable energy supply. Through innovations in technology and management, we consistently make breakthroughs in energy exploration, development, production and technology research. CNOOC Limited makes great effort to ensure the steady supply of energy to satisfy reasonable demand from society and promote the sustainable development of both the Company and society.


Oil and Gas Exploration, Development and Production


One of CNOOC Limited’s main responsibilities is to ensure the stable supply of crude oil and natural gas. To achieve this goal, the Company has pursued innovation in technology, management and equipment for a long time. The Company consistently overcomes difficulties in exploration, actively drives the integration of exploration and development in order to improve product quality and work efficiency. The Company continuously expands oil and gas reserves and production at a steady pace, and manages for better oil and gas development and production.


In 2018, CNOOC Limited devoted greater effort in its oil and gas exploration, and its exploration activities reached a record high. Adhering to value-driven and business exploration and anchoring on its exploration and discoveries of mid-to-large sized oil and gas fields, several major discoveries were made. This continuously maintained a good development momentum of oil and gas exploration. Various exploration breakthroughs were achieved in new frontier areas in offshore China, and a strategic core exploration area was gradually formed on both sides of the Atlantic Ocean. Our management capability and technological innovation capability have been further enhanced, and the efficiency of exploration operations has been significantly improved. In addition, the Company continued to maintain a reasonable proportion of exploration investment and a relatively high level of exploration activities so as to ensure mid-to-long term sustainable development. In this year, 17 commercial discoveries were made and 17 successful appraisals of oil and gas structures were achieved. Weizhou 6-13 Oilfield and Penglai 19-3 oilfield 1/3/8/9 comprehensive adjustment project in offshore China as well as Stampede Oilfield in the U.S. Gulf of Mexico, came on stream. By overcoming various challenges, we have successfully met our production and operation targets.


In 2018, the Company ensured base production level and laid a solid foundation for production profile of existing oilfields through refined management. Meanwhile, we strictly controlled costs, encouraged conservation and improved efficiency. Furthermore, we coordinated devoted great efforts in promoting “the water injection year” work of Bohai oilfield in order to further tap the potential of producing oilfields received favorable results.


Gas field of 100 billion cubic meters scale was discovered in the Bohai Bay


As accredited by the Oil and Gas Reserves Accreditation Office of the Ministry of Natural Resources of the People’s Republic of China, the proved in-place volume of natural gas in the Bozhong 19-6 gas field exceeds 100 billion cubic meters, while the proved in-place volume of condensate exceeds 100 million cubic meters. As the largest natural gas field in the Bohai Bay, the Bozhong 19-6 gas field will contribute more to the "lucid waters and lush mountains" of the Bohai-Rim-Region with low-carbon energy.

The production of the Eastern South China Sea Oilfield exceeds 15 million cubic meters for the fourth consecutive year


The Eastern South China Sea Oilfield was faced with many challenges including frequent and strong typhoons, dock repair work of two tankers, as well as offline maintenance of several oilfields in 2018. By expanding oil and gas exploration and development, conducting streamline management, and constructing smart oil fields, the overall production and operation safety were ensured, and the oil and gas production exceeded by 7.34%. By end of the year, the Eastern South China Sea Oilfield had produced more than 10 million cubic meters of oil and gas per year for the twenty-third consecutive year since 1996, and produced more than 15 million cubic meters of oil and gas per year for the fourth consecutive years since 2015.




Securing a Stable Supply of Natural Gas


In order to meet domestic demand for natural gas and develop a low-carbon economy with energy consumption and emission reduction through energy structure transition, the Company has optimized our production schemes, to improve our upstream productivity. Meanwhile, we employed a reasonable price to stabilize the natural gas market. Natural gas demand is secured with the Company’s efforts on providing and promoting clean energy.


Increase production and supply:


We arranged for overhauls on upstream and downstream to make sure our producing gas fields are operating safely, and at the same time produce at full capacity. In 2018, the Company supplied natural gas 12.8 billion cubic meters, which exceeds the annual plan by 800 million cubic meters, contributing to the overall supply of natural gas.


Ensure sufficient natural gas supply in Hong Kong:


As China’s largest offshore gas field under production sharing contract, the Yacheng 13-1 Gas Field has supplied gas for residents in Hong Kong for 23 years, providing a stable and clean energy for the economic and social development of Hong Kong.


Prepare for emergencies in advance:


The quantity of natural gas supply was settled at the end of September, 2018. Meanwhile, the Company put more emphasis on trend research and forecasts, signed interruptible gas contracts with users and made clear supply priorities, making full efforts to meet residents’ gas demand.


Technological Development


In 2018, CNOOC Limited proactively implemented its “innovation-driven” strategy, deepened the reform of the technology system and mechanism, and kept improving its technological innovation system. Within the reporting period, the Company launched the construction of scientific research platforms such as the Key Laboratory of Geophysics, the Key Laboratory of Enhanced Oil Recovery, the Key Laboratory of Deepwater Engineering, and the Offshore High-temperature and High-pressure Oil and Gas Reservoir Exploration and Development Laboratory. Meanwhile, the “State Key Laboratory of Offshore Oil Exploitation” was assessed as “outstanding” in the evaluation by the Ministry of Science and Technology of China which is hosted once every 5 years. The construction and operation of the laboratory receives national recognition.


During the year, the Company continued to develop key technologies for exploration and development of deep-water oil and gas fields, offshore viscous oil, low-permeability oil and gas fields. We have achieved remarkable results including “Rock-Crust-Fracture” Reservoir Evaluation Technology Series of Metamorphic Reservoirs, Tapping Strategy of Injection-production of Development Well Pattern Based on Fine Characterization of Reservoir Model, Key Drilling and Completion Technologies for Deep-water Development Wells in the South China Sea, etc. These technologies provide technical support for reducing cost and increasing efficiency, and expanded oil and gas reserves and production. The establishment of “Key Technologies Study of the Continuously Stable Production of 30 Million Tons Oil of Bohai Oilfield” provided a strong technological support for the production of Bohai oilfield.





Findings of key national science and technological projects support stable production of 30 million tons in the Bohai Oilfield


In 2018, the key national scientific and technological project “Key Technologies for Mid-depth Seismic Exploration in Offshore China” successfully developed an offshore wide-azimuth seismic acquisition design technology, and improved sub-azimuth acquisition and OVT (Offset Vector Tile) domain design and evaluation method, forming a quantitative evaluation technology system for wide-azimuth observation systems. Using this technology, the Company completed wide-azimuth seismic acquisition design for submarine cables on buried hills in the Bozhong 19-6 Oilfield. The technology provided strong technical support for seismic data acquisition in an area of 1,820 km2, helping achieve the major target of stable production of 30 million tons oil and gas in the Bohai Oilfield, and facilitating our full implementation of secondary 3D seismic acquisition.

After-effect perforation significantly increased production in Lufeng 13-1 Oilfield


In Lufeng 13-1 oilfield, we actively explored new methodology to increase production of low-porosity and low-permeability deep layer oil reservoirs. We applied the after-effect perforation technology to two directional wells and received significant results. After the application of the technology, the production of the two wells increased significantly. The production capacity index of the directional wells was approximately 3 to 4 times higher than conventional perforation, whose performance was much better than similar deep directional wells. The successful well stimulation method created a new way to further tap the potential of producing oilfields.

Research breakthroughs - another frontier in oil and gas exploration


In 2018, the Shenzhen branch made a technological breakthrough in the Yangjiang Sag, Pearl River Estuary, Northern South China Sea. Based on newly acquired 3D seismic data, as well as a systematic study of structure, sedimentology and reservoir formation, we made a series of geological discoveries. The Shenzhen branch proposed a specific geologic pattern of reservoir difference control, developed a key technology for complex mid-depth fault block image processing and bright-spot oil and gas recognition of mid-shallow layers. This research allowed us to identify an advantageous reservoir formation zone in this area and an exploration region target. After exploration drilling, oil reserves were discovered in the Neogene marine sandstone formation. By successfully discovering a frontier area, in which there have been no significant discoveries for over 40 years, we have developed a new growth point for our oil and gas reserves and production.


Patents and Intellectual Property Rights


In order to ensure and protect intellectual property, the Company has formulated and implemented management methods such as CNOOC Limited Intellectual Property Management Measures and CNOOC Limited Patent Management Implementation Rules. Besides, internal control inspections of intellectual property rights were carried out by the Company.


In 2018, there were 115 patents granted, 278 patents accepted and 14 software copyrights registered. The patent for the equivalent characterization method of reservoir genetic unit interface won the 12th China Patent Excellence Award. Meanwhile, we released 48 standards, including 4 national standards, 4 industry standards, and 40 company standards. One of the standards, SY/T 7391-2016: Underwater Emergency Blowout Equipment, was awarded the first prize for Standard Innovation and Contribution by the National Petroleum Drilling and Production Equipment and Tool Standardization Technology Committee in 2018.

CNOOC Limited follows international industry practices, benchmarks against peer performance, and complies with international and domestic quality management systems to produce and supply energy products. We provide clients with qualified crude oil and natural gas products in accordance with international standards, national standards jointly published by the State Administration for Market Regulation and the Standardization Administration of China, contractual provisions on natural gas quality agreed with clients, and the latest crude oil standard of GB 36170-2018.


CNOOC Limited has invited renowned internationally inspection agencies and state-certified commercial inspection agencies to inspect and test the quality of crude oil and natural gas, such as the Exit-Entry Inspection and Quarantine Bureau. Based on the result of the inspection, the third-party inspection agencies issued objective and accurate test reports. We managed the quality of products publicly, transparently, in compliance with laws and regulation, and strictly. At the end of 2018, we had not received any client complaints regarding our crude oil and natural gas products and services. Should any complaint arise, we will actively communicate with the clients in accordance with the signed contracts and national standard GB 36170-2018, and properly handle the complaint to protect their interests from any loss.


Procurement Management


CNOOC Limited has established and implemented a series of management policies, including the Procurement Management Measures, Supplier Management Methods, and Bidding Management Methods. Based on these policies, the Company carries out supplier management and bidding procurement tasks, avoiding environmental and social risks caused by improper choice of suppliers. Since 2008, CNOOC Limited has continuously optimized supply chain management and implemented a supplier database management system. Upon the end of 2018, the Company had more than 3,500 suppliers, including about 270 overseas ones.


By sharing supplier information and optimizing performance assessment, the Company dynamically manages the entire process, from onboarding to offboarding. In 2018, we continued to shortlist suppliers through public qualification examinations in written form and on-site investigations. We invited internal and external experts for on-site investigations of more than 50 suppliers in four product categories: oil casing, steel, transformers, and valves. During the investigation, we comprehensively assessed suppliers’ qualifications, CSR performance, risk control, process control, quality control, personnel quality, technological capability, and HSE management, establishing a strategic cooperation relationship with shortlisted suppliers. We annually evaluate the performance of all suppliers in our database, including but not limited to their product quality, price, date of delivery, after-sales service, and HSE execution. We then adjust their ratings and update the database accordingly. The Company has also established a risk control system to handle violations of regulations, enhancing our ability to control overall supplier management risk.


In addition, our Procurement Management Measures include regulations on supplier management, qualified supplier selection and credit rating. We conduct supplier audits, inspect supplier management systems, application processes and evaluation processes, and review the quality of our daily management and supervision of suppliers. We have included anti-bribery provisions in a wide range of contract templates, articulating the corresponding legal consequences.





The Eastern South China Sea Oilfield refines supply chain management


In 2018, the Procurement Sharing Center of the Eastern South China Sea Oilfield introduced a new procurement method and visualized general material procurement management through the online “material delivery platform”, enabling intelligent management of the process. Meanwhile, the Center strictly controlled incremental inventory, and optimized the stock inventory. The Procurement Sharing Center connected the production operational plan and the inventory information effectively, improving the utilization of inventory and the accuracy of the demand plans. Through this method, advanced purchasing and excess reserves were avoided.

We seek to identify and punish Should there be any practice of employee corruption and and malpractice with no exception, we would take down with no exception.


The Company has a high ethical standard for behaviors of its employees. It requires employees to stick to integrity and self-development with self-discipline and honesty. In order to strengthen the internal management of the Company, improve the self-discipline of employees, and ensure that the Company's production and business activities proceed smoothly without business ethics violation, the Company has formulated a set of rules and established an effective system to punish and prevent fraud, such as the The Code of Commercial Behavior and Conduct of Employees of CNOOC Limited, The Procedures for Handling Rule Violations, Regulations on Conflicts of Interest, Petition and Visiting Reporting and Appeal Management Measures, and Financial Control Complaint Management Measures. All new employees receive training on the contents of all such documents and sign a letter of confirmation about The Code of Commercial Behavior and Conduct of Employees of CNOOC Limited.

Equipment and Facility Integrity Management


To produce quality products, the Company has been relentlessly perfecting its management in keeping the equipment and facilities integrated and working smoothly to maintain safe and clean production for the Company. We have seen a steady downward trend in our safety accident rate, and the rate of breakdowns on production dropped after the bounce back in 2017, resulting in a drastic decline in accident impact by the measure of average repair costs for individual facilities.


In 2018, as we continued our efforts in refining the management system, we issued the CNOOC Limited Equipment and Facilities Integrity Management System (Version B) and made revisions for 50 documents and 332 clauses. In August 2018, we invited Det Norske Veritas (DNV GL) to conduct a pilot audit of the integrity management of equipment and facilities on our Shenzhen branch, and verification from the independent third party showcased the considerable progress we have made in integrity management implementation.





We have a regular mechanism for risk identification and elimination of potential equipment and facilities, “fastening the seat-belt” for our production and operations. We have prioritized the inspection and maintenance of submarine pipelines, floating production equipment, drilling rigs, wellbores and electrical equipment. In 2018, we conducted random examinations at our branches on equipment and facilities safe operations, further strengthening the supervision and process control.


We launched a three-year action plan for environmental protection in the Bohai Oilfield. Following the action plan, we detected potential hazards for submarine pipelines, installed riser protection racks and controlled annulus access flow for risers. In addition, we added requirements to the baseline tests on all new pipelines in the Bohai Bay, and embarked on power supply planning in the Bohai Oilfield.


2018 Equipment and Facilities Design Integrity Audit and Production Adaptability Assessment:


·       Completed integrity audits on 10 projects in the preliminary research stage, such as the Lingshui 17-2 gas field.


·       Completed integrity audits on 7 projects in the production stage, such as the Enping 23-1 oilfield.





Impact rate of equipment and facilities breakdowns on production (breakdown impacted/planned output)


Dock repair of South China Sea Shengli and Offshore Oil 111 FPSOs


In 2018, due to serious corrosion of the cabin and subsea valves of the South China Sea Shengli Floating Production Storage and Offloading (FPSO) unit, the mooring rope broke and the mooring chain was badly abraded. As Offshore Oil 111 FPSO was seriously corroded as it was approaching the end of its service life, the Shenzhen branch carried out thorough dock repairs on two of the FPSO units. It took more than two months to replace the severely corroded hull parts and all potential hazards identified were eliminated. Both FPSOs are now in great form, have been put back into production and operation, and are well-prepared for future safe production.






Enhance Emergency Response Capability


The Company focuses on strengthening its emergency management in establishing an emergency rescuing system that emphasizes emergency preparedness and prevention. In 2018, the Company remained committed to improving the collaborative emergency response mechanism and the Tianjin branch hosted a joint emergency drill with CNOOC Limited, Sinopec and CNPC. The drill further tested and upgraded the Company’s capabilities for emergency response and participating in regional coordination with Sinopec and CNPC.


In 2018, the Shenzhen, Zhanjiang, and Shanghai branches were struck by typhoons 12 times, from Ewiniar on June 4 to Yutu on October 26. We mobilized 68 ships and 761 helicopters, evacuated 16,238 people at sea, and effectively responded to emergencies.


Mangkhut, the most violent typhoon of the year


With the 22nd typhoon, Mangkhut, approaching in 2018, we carried out overall deployment following the requirements of the Ministry of Emergency Management of the People’s Republic of China and the Company’s typhoon emergency plan. We maintained close communications with the National Meteorological Center of CMA as well as Emergency Response Departments around the clock to supervise the preparation. Offshore facilities with a total of 5,365 people were evacuated in advance with 230 helicopter trips and 39 sea trips.


The Shenzhen branch organized the evacuation for its entire responsible area, activated the "Typhoon production mode" for offshore gas fields, and delivered about 45 million cubic meters of natural gas by unmanned production. The Zhanjiang branch provided temporary electricity generators to ensure continuous power supply during the typhoon.

Launching the “Well Control Week” Activities

We have elevated the security for infrastructure, production systems and sensitive data, and boosted our defenses against cyber-attacks, providing strong protection for company operations.


The European and North American Subsidiaries Enhanced Data Security Management


On May 28, 2018, the EU's General Data Protection Regulation (GDPR) officially took effect, which had great implications for our Europe and North America subsidiaries operations. Seeing the regulation coming ahead of time, the European and North American subsidiaries set up special taskforces a year before its release and conducted deep research on data protection. The taskforces developed a data protection upgrade plan to ensure that the subsidiaries transition smoothly and comply with the regulations in the shortest term possible. After the introduction of the regulation, the taskforces made prompt updates on relevant procedures, contracts and privacy provisions, and carried out activities such as interpretation of regulations and online training for all employees, keeping them informed of key terms of the regulation, as well as their rights and obligations in data protection. As the result, data security was strengthened by employees and suppliers and the subsidiaries as a whole according to the new standards.





Environmental Protection


CNOOC Limited fulfills corporate responsibilities for environmental protection in all aspects and in a multi-dimensional way, strictly managing our environmental performance throughout the operational process, and improving water utilization efficiency. The Company is fully committed to protecting marine ecology.


Environmental management


Adhering to the idea of a “Green, Low-carbon, Clean, and Circular Economy”, the Company has stepped up our efforts to become an “Energy-saving and Environmentally friendly” enterprise, and has continuously implemented environmental management.


Following the management principle of “in-process control better than post-control, pre-control better than in-process control, and whole process control better than pre-control”, the Company has managed environmental protection with environmental impact assessment as the core. Using the CNOOC Limited Environmental Protection Management Information System as the platform, we have performed environmental protection management, emphasizing strict environmental impact assessment, pollutant emission monitoring and overall emission reduction throughout the project construction process.












Note: The scope of the environmental data in the report only includes the Tianjin, Shanghai, Zhanjiang, and Shenzhen branches, and excludes China United Coalbed Methane Co., Ltd. and overseas units.

Under the framework of ecological protection, the Company has put significant effort into green development, imposed rigorous control of marine environmental protection, and complied with the requirements of the Environmental Protection Law. During the year, the Company continued to revise the marine environmental protection system through the Regulations on the Environmental Impact Assessment of Domestic Offshore Oil and Gas Fields and the Management Rules for the Completion of Environmental Protection Facilities in Domestic Marine Oil and Gas Development Projects, which effectively reduced environmental risks and potential hazards at various stages, and improved the Company's environmental management.


In 2018, in response to the Group's environmental risk investigation, the Company carried out comprehensive marine environmental risk investigation and environmental hazard control. We conducted environmental protection supervision on key environmental risks to complete environmental hazard remediation.


Meanwhile, the Company performed annual special emission compliance monitoring on offshore platforms, and strengthened the supervision of pollutant discharge in the production process. We consolidated the monitoring of key environmental protection processes through information technology, carrying out special environmental inspections and promoting rectifications to achieve a coordinated and healthy development relationship between production and environmental protection by continuously regulating environmental management.


Regarding the management and control of hazardous chemicals in the oilfield, we adhere to the five principles of locating, quantifying, designating persons in charge, specifying accountability and timing. We clarify the properties of hazardous chemicals, determine the location of hazardous chemicals, and include hazardous chemical management in the safety production procedures to fix flaws and prevent risks.

The Shenzhen branch strictly controlled production-used water discharge to mitigate pollution
In 2018, the concentration of petroleum hydrocarbons in production water and the COD in domestic sewage from the offshore facilities of the Shenzhen branch were both lower than the national emission standard. In particular, the concentration of petroleum hydrocarbons was lower than the national standard by 50%, and was eligible for the reduction and exemption of national environmental protection tax.


Water Resource Management


Adhering to the principle of “paying equal attention to developing reserves and reducing usage, giving priority to conservation” and focusing on improving the utilization efficiency of water resources, the Company strengthens technological transformation and promotes comprehensive treatment and reuse of wastewater to conduct all-around water resources management.


In 2018, the Company prioritized water conservation at all levels by setting specific tasks and indicators for all subsidiaries, and implemented multiple management and technical measures on water conservation. For example, freshwater conservation was achieved through measures such as seawater desalinization; the Company consumed less freshwater per unit of production by optimizing the production process; employees' awareness of water resources crisis and water conservation was enhanced by active water conservation promotion.


Indicator Unit 2016 2017 2018
Total Freshwater Consumption Million tons 1.879 1.813 1.859
Freshwater Consumption Per Ton of Oil and Gas Production Cubic meters/ton 0.0335 0.0332 0.0335
Water saving Thousand tons 113 88 108

Penglai 19-3 Oilfield RUP Platform Turbine Flue Waste Heat Seawater Desalination Project (Phase II)


The RUP platform of Penglai 19-3 Oilfield contains two gas turbines. We installed a heat exchanger on the turbine flue to transfer the heat from the gas to the circulating water. With a pump circulating hot water, the absorbed heat from turbine gas is brought to distill seawater for freshwater. The project is divided into two phases: the 2017 and 2018. After being put into operation, it produces 18,000 tons of freshwater per year, which not only helps realize the water self-sufficiency for production and for people to live on this facility, and also can supply freshwater to the surrounding offshore platforms, significantly reducing the frequency of water exchanges between ships and effectively saving production costs.





Marine Ecological Protection


The Company has fulfilled the requirements outlined in the Measures for Environmental Protection Management During Production and Measures to Manage Accountability for Environmental Damages, and has strictly maintained our ecological “red line” for harmonious coexistence with the ocean to achieve mutual benefits. For newly built and refurbished environmental protection projects, we have implemented the Measures to Manage Newly Built and Refurbished Environmental Protection Projects.


In 2018, we actively participated in environmental protection initiatives, focusing on research and protection of biodiversity, and promotion of resource restoration and environmental improvement in the operating regions. We sponsored a variety of projects such as protection, artificial propagation and release of spotted seals.


Active restoration, artificial propagation, and release of fishery resources


Artificial propagation and release is a way to actively reduce the impact of marine engineering on the environment. In 2018, the Shenzhen branch restored, artificially propagated, and released fishery resources for the Enping 23-1 Oilfield Project, with a total of more than 3 million pompanos, black porgy, sparus latus and more than 31 million giant tiger prawns released. While increasing the amount of biological resources in the area of artificial propagation and release, we also improved the ecological community structure to realize ecological, social and economic benefits.

Protection of marine wildlife


CNOOC Limited takes part in measures to protect the marine ecological environment. The offshore operation areas often become a refuge for wild animals, and marine life which are highly demanding on their habitats such as national-level protected wild animals.


• Rescue a Lost Falco: Employees in Weizhou Oilfield found a national level 2 protected falco subbuteo, during a deck inspection. According to initial judgment, it was foraging in the water near Weizhou Island, lost direction in the strong and cold winds, and landed on the platform. The bird was taken good care of for a week, and it eventually recovered and flew away.


• Rescue an Entangled Hawksbill Turtle: During the inspection of Ledong 22-1 gas field, a hawksbill turtle (national level 2 protected wild animal) was entangled tightly in a fishing net near the jacket. The turtle was rescued and released into the sea.


• Rescue an Injured Finless Porpoise: Employees on platform C of Penglai 19-3 oilfield immediately arranged for the standby ship, HYSY 688, to rescue a finless porpoise upon notice. The animal was trapped 50 meters northwest from the platform. In 5 minutes, the ship arrived and quickly took the injured finless porpoise onboard. Upon inspection, the finless porpoise was marked with multiple scars from fishing nets. After about 20 minutes, the net was untangled; the finless porpoise recovered and was released.

Ecological Restoration by CNOOC Nexen Company






In 2015, CNOOC Nexen Company discovered a pipeline release of a mixture of bitumen and water at our Long Lake Oil Sands operations in Fort McMurray, Alberta, Canada. Together, teams quickly collaborated with internal and external stakeholders and built comprehensive plans to support the remediation efforts in a unique muskeg (swamp like) environment. This included working with local stakeholders (e.g. Aboriginal communities, Regional Municipality of Wood Buffalo community members, etc.) and the Alberta Energy Regulator (AER) to maintain regulatory compliance and ensure all relevant stakeholders’ views were considered and incorporated into our plans.


Wildlife protection measures:


• Installed fences and flags to deter ungulates such as deer, bears, foxes and coyotes.


• Placed predator effigies and scare canons to deter birds and other small wildlife.


• Engaged qualified wildlife biologists to observe the release site.


• Placed white silage tarps on the exposed bitumen to deter birds from thinking it was a landing spot.


Ecological and environmental remediation:


Due to the remote location of the release site and the swamp-like vegetation (muskeg), extra remedial steps were required. This included:


• Using coconut matting as a barrier to contain the release.


• Using rig mats to help construct roads to get to the site.


• Waiting until the outside temperature cooled to start excavating, as this would help solidify the bitumen and reduce the environmental impact and waste volume from remedial activities.


• Taking confirmatory samples from the bottom of the excavation to determine if any further work was required.


• Moving soil to synthetically line holding cells to prevent further seepage into the muskeg.


• Backfilling the release site with clean peat once samples were determined clean.


• Trucks safely following a haul plan to transport material to the landfill.


Solid and fluid waste management measures:







CNOOC Nexen Company accomplished site closure within two years with no requirements for long term monitoring. Shortly after the AER Environmental Protection Order was lifted, the site was given back to operations. Today, the release site looks like any other pipeline right-of-way in the region, with natural vegetation returning to pre-disturbance health and abundance with no outstanding visual evidence of the release.




Response to Climate Change


As a responsible energy company, we adhere to the concept that “lucid waters and lush mountains are invaluable assets”. With our low-carbon strategy implemented, we strive to promote clean energy and improve energy efficiency, and boost energy-saving and emission-reducing projects to proactively tackle climate change.





Energy Conservation


In 2018, we upgraded and optimized our energy and carbon control system to automatically collect energy invested consumption data from key energy-consuming units. The Company invested special funds for energy conservation and emission reduction, and promoted energy conservation and emission reduction via technological advances. We implement systematic energy conservation based on a clear and complete organizational structure. With division of work and management principles as the parameters, we carried out energy conservation planning covering fixed asset energy conservation evaluation methods, special funds management and publicity work for energy conservation. Procedures pertinent to energy conservation management were articulated and incorporated into our overall risk management system. In addition, we have also carried out extensive energy-saving publicity and education to boost employees’ energy-saving awareness.


In 2018, we increased our investment in energy conservation and emission reduction, transforming technologies to achieve our targets. This year, we rolled out 39 technology transformation projects to achieve energy conservation goals, with total investment of RMB 210 million. Nanshan Terminal of the Zhanjiang branch was awarded as a "Green Factory" in the petroleum and petrochemical industry. In 2018, the Company saved energy equivalent to 165 thousand tons of standard coal.


In 2018, the Company organized the revision of five enterprise energy-saving standards, including the Guidelines for Construction of Online Energy Consumption Monitoring Systems, Guidelines for Utilization of Residual Heat and Pressure in Offshore Oil and Gas Fields and Guidelines to Evaluate Green Plants in Offshore Oil and Gas Fields.

Its small compressors were repaired and rebooted to recycle and utilize the associated gas, extending the production life of the field. After completion of the project, 45,000 cubic meters of natural gas were recycled each day. From January to December 2018, a total of 11.48 million cubic meters of gas was recycled, conserving 15,269 tons of standard coal equivalent and reducing 24,822 tons of CO2 emissions equivalent. The annual economic value created was RMB 18.36 million.

Bozhong 34-2/4 CEPA Platform low-pressure natural gas recovery project


In the Bohai Oilfield, we introduced low-pressure gas recovery technology. In 2018, we selected the Bozhong 34-2/4 CEPA platform as a pilot and applied jet supercharging technology for the first time. The gas released from the secondary separator was recovered, exemplifying the Venturi effect. With the recovery capacity of 3 million cubic meters of low-pressure gas, it could reduce 7,200 tCO2e of GHG emissions.


Low Carbon Management


Under the instructions of the Plan to Control Greenhouse Gas Emissions under the 13th Five-Year Plan (NDRC Document No. 61 [2016]), the Notice on Earnestly Launching a National Carbon Emissions Trading Market (NDRC Climate Document No. 57 [2016]) and other relevant documents and policies in China, the Company manages energy conservation, emission and carbon reduction throughout the year and tackles major issues. We set up a set of metrics and KPIs for energy conservation and carbon emission reduction in light of the regulations, and reviewed the annual performance of subsidiaries accordingly.


In 2018, we established a low-carbon management system with reference to the national policies and practices of leading energy companies in China and abroad as well as requirements to implement climate and carbon management. The system was found based on one measure and five rules: Low Carbon Management Measures, Rules for Carbon Emission Statistics and Reporting, Rules for Carbon Emission Impact Assessment and Review of Fixed Asset Investment Projects, Rules for CCER2 Project Development Management, Rules for Carbon Asset Management, and Rules for Carbon Assessment. Through this system, the Company has worked out the “division of work” for the overall carbon management and the corresponding data collection methods, and laid out managing rules for carbon reduction work including CCER projects, carbon evaluation and carbon assets assessment.


2 CCER: According to the Interim Measures for the Administration of Voluntary Emission Reduction and Trading of Greenhouse Gases, the quantity involved in voluntary emission reductions shall be registered and recorded by the national competent authorities in the National Voluntary Emissions Reduction Transaction Register. The quantity in emission reduction is called "Chinese Certified Emission Reduction (CCER)". After the registration of voluntary emission reduction, the carbon emission can be traded in registered trading institutions of China.





In 2018, we initiated the compilation of a "Green Low-Carbon Development Roadmap" and its implementation plan, which outlines the short-term, medium-term and long-term carbon emission reduction action plans for the Company. The Plan aims to optimize and integrate the energy control and low-carbon management information system that combines production with energy saving and carbon emission reduction. We have made a more progressive annual plan on energy-saving and low-carbon targets, incorporating KPIs of carbon emissions, emission intensity and emission reduction completion into the performance evaluation of each unit.


In 2018, the Company further optimized its technology, evaluation, and management systems regarding carbon emission impacts, and formulated standardized procedures and work flows. During the year, our research center analyzed and researched the feasibility of carbon dioxide storage and CO2 flooding technology in offshore oil and gas fields, keeping an eye on related advanced technologies, focusing on both preliminary research and technology application. We conducted carbon dioxide engineering application transformation projects in Shenzhen, Zhanjiang and Shanghai and formulated the implementation plan and application exploration.


In 2018, we conducted carbon emission impact assessments and audits of fixed asset investment for projects that consumed more than 20 thousand tons of standard coal equivalent of comprehensive energy or produced more than 10 thousand tons of CO2 equivalent of GHG direct emissions. In total, we have conducted six projects, including assessment of the Lingshui 17-2 Gas Field and Luda 6-2 Oilfield. We verified the carbon emissions of companies that are subject to emission control, and urged companies participating in the pilot carbon trading program to comply with regulations and fulfill their contractual responsibilities. We developed the CNOOC Limited Carbon Asset Management Plan and participated in state-led studies on carbon emission benchmarking to improve comprehensive carbon management.

Green management concepts in offshore oilfields


The Company has minimized the impact of offshore oilfield development by shifting from supplying power, gas, and water individually to establishing a regional network that provides oil, gas, water, power, information and offshore and onshore internet.




No drilling before proper environmental protection measures in place.
No oil contamination discharged into the sea.
No litter generated in any form.
Aiming for zero pollution, protect the environment from the source.



Construction was scheduled to circumvent the fish spawning period (as the main economic product in the area) and reduce the impact on fishery resources and the marine environment.




Hundreds of oil extracting platforms aim for “no leakage from equipment and no oil contamination on the platform,” acting as guardians of the blue ecosystem. For example, our platforms have achieved near-zero sewage discharge.








Offshore wastewater management


In the Nanpu 35-2 Oilfield, all domestic sewage was treated. Wastewater such as gray water from kitchens, toilet water and other waste was collected and treated by bacterial decomposition. To ensure the effectiveness of the treatment system, tanks were regularly cleaned to remove non-degradable dirt and transport it back to land for treatment. After a series of treatments, sewage such as flushed toilet water met national discharge standards.


Offshore emergency response team


The Bohai Oilfield has a leading offshore emergency response team among global oil companies in terms of oil spill response capability. Emergency exercises are held every week on hundreds of offshore facilities to continuously improve emergency responses. Meanwhile, the teams also promptly clean up garbage produced by passing ships. The Company Postdoctoral Environmental Protection Research Station also developed bioremediation technology for shoreline oil pollution, using bacteria and fungi to consume crude oil and release environmentally harmless substances. The station has played a leading role in the industry in accelerating the self-recovery of the marine environment.
