China National Offshore Oil Corporation (CNOOC) announced on Thursday that it has discovered a high-yield volcanic rock oil and gas well in an ultra-deep formation exceeding 5,000 meters in the Bohai Sea. Testing showed a daily natural gas production of approximately 800,000 cubic meters (28 million cubic feet) per day, marking a major breakthrough for China in the field of offshore ultra-deep natural gas exploration. The well, located in the central Bohai Sea, reaches a total depth of 5,770 meters (some 3.6 miles). During the exploration process, the well encountered more than 120 meters of natural gas-bearing layers in volcanic rock formations, fully demonstrating the vast exploration prospects of the offshore ultra-deep volcanic rock sector in the region. 📺 Subscribe to our YouTube channel and stay updated with our latest analysis and interviews:👇 https://www.youtube.com/channel/UCgrNz-aDmcr2uuto8_DL2jg 👈 Download our APP on Apple Store (iOS): https://itunes.apple.com/us/app/cctvnews-app/id922456579?l=zh&ls=1&mt=8 Download our APP on Google Play (Android): https://play.google.com/store/apps/details?id=com.imib.cctv For more: https://news.cgtn.com/news/2026-11-12/China-makes-major-breakthrough-in-ultra-deep-gas-exploration-1S0V1IynTHi/p.html Most watched videos: Impossible Challenge: 30 seconds to count banknotes BLINDFOLDED https://www.youtube.com/watch?v=ZmP_Ybj-jws Impossible Challenge: Gymnastics Boy Arat Hosseini from Iran! https://www.youtube.com/watch?v=8sxX--U4c8w Impossible Challenge: How to calm babies in 5 seconds? https://www.youtube.com/watch?v=kR3q9sXM7WA
