On April 16, China National Offshore Oil Corporation (CNOOC) announced the efficient completion of drilling operations at an ultra-deepwater exploration well in the South China Sea, achieving a record-breaking drilling cycle of just 11.5 days—the fastest for China’s ultra-deepwater drilling at depths of 3,500 to 4,000 meters. This milestone validates the advanced capabilities of China’s independent deepwater drilling and completion technology system, showcasing its technical expertise in ultra-deepwater operations. The breakthrough holds significant importance for scaling up deepwater oil and gas resource development, supporting China’s goal of maintaining crude oil production at 200 million tons, and accelerating deep-sea energy exploration.
Offshore drilling and completion operations are characterized by high risks, high costs, and cutting-edge technologies, while deepwater operations present even greater complexity and implementation challenges. Currently, China’s deepwater drilling and completion technologies and operational capabilities rank among the world’s most advanced.
CNOOC has developed a distinctive deepwater drilling and completion system with Chinese characteristics, featuring its innovative “Smart Excellence” technological framework and lean management model. By decomposing deepwater operations into hundreds of standardized procedures and coordinating multiple specialized technical teams, the company ensures safe, high-quality and efficient execution throughout the entire deepwater drilling and completion process.
Deep-sea oil and gas development represents a critical frontier in global technological innovation. Looking ahead, CNOOC’s deep-sea development technologies will advance toward greater depths and higher efficiency. Through digital and intelligent empowerment, the industry will achieve a transformation from experience-driven operations to data-driven, intelligent decision-making.
We will continue to pursue technological innovations, eg. our company’s Highly anti-erosion Ceramic Hydrocyclone Desanding Systems、High-efficiency Hydrocyclone Oil Removal System、Compact Injet-Gas Flotation Unit (CFU), and other products in order to keep pace with industry advancements to contribute those cutting-edge solutions and sustainable development to global energy exploration.
