China National Offshore Oil Corporation (CNOOC) has successfully commenced production at two major offshore oilfield projects: the Caofeidian 6-4 Oilfield Comprehensive Adjustment project and the Wenchang 19-1 Oilfield Phase Two project. These developments mark significant milestones in CNOOC's continued efforts to enhance domestic energy production while employing innovative and environmentally sustainable practices.

Located in the western region of the Bohai Sea, the Caofeidian 6-4 project is positioned in shallow waters averaging 20 meters deep. The development features a newly constructed production wellhead platform that leverages nearby existing infrastructure. The project aims to bring 25 development wells online, comprising 22 for oil extraction and three for water injection. Peak production, anticipated by 2026, is expected to reach approximately 11,000 barrels of oil equivalent per day (boepd) with light crude oil properties. This production is poised to contribute significantly to China's growing energy demands and strengthen its oil supply chain.

Meanwhile, the Wenchang 19-1 Oilfield Phase Two project is located in the western section of the Pearl River Mouth Basin, with an average water depth of around 125 meters. This initiative will introduce 13 development wells, with peak production estimated at roughly 12,000 boepd by 2027. The crude oil extracted here is classified as medium crude. This project is expected to play a crucial role in supporting China's energy security and stability, particularly in coastal regions reliant on offshore resources.

Both projects incorporate intelligent oil and gas field design concepts, enhancing hydrocarbon recovery efficiency. By integrating smart technologies, CNOOC has improved crude oil production processes, equipment maintenance, and safety management. These advancements enable streamlined operations, reduce downtime, and improve overall productivity, ensuring maximum resource utilization.

In line with CNOOC's environmental commitment, the Caofeidian 6-4 project includes a gas reinjection system that redirects associated gas back into the reservoir. This innovative method significantly reduces greenhouse gas emissions, with an estimated reduction of 13,000 tonnes of carbon dioxide annually. This reinjection process not only minimizes environmental impact but also improves reservoir pressure, enhancing oil recovery rates.

Similarly, the Wenchang 19-1 project employs a megawatt-level, high-temperature flue gas Organic Rankine Cycle (ORC) power generation unit. This cutting-edge system is designed to generate up to 24 million kilowatt-hours of electricity annually, potentially lowering CO2 emissions by around 23,000 tonnes per year. By harnessing waste heat for power generation, this technology further demonstrates CNOOC's dedication to sustainable practices and resource efficiency.

CNOOC continues to reinforce its status as China's leading offshore crude oil and natural gas producer. The company's core business activities focus on exploring, developing, producing, and marketing crude oil and natural gas resources. With these new projects, CNOOC is set to enhance its production capabilities while implementing forward-thinking environmental initiatives, supporting China's long-term energy security and economic growth.
