Group 1 - The "Deep Sea No. 1" gas field, located in the Hainan Lingshui sea area, is China's deepest and most challenging offshore gas field, with a maximum operational water depth exceeding 1,500 meters and a geological temperature of up to 138 degrees Celsius [1][4]. - The gas field has proven geological reserves of over 150 billion cubic meters of natural gas and is being developed in two phases [1][4]. - Currently, "Deep Sea No. 1" produces 15 million cubic meters of natural gas and over 1,600 tons of condensate oil daily, with some condensate stored in oil storage tanks on the platform and exported via shuttle tankers [1][4]. Group 2 - Since its commissioning in 2021, CNOOC's operational team has continuously upgraded the production facilities of "Deep Sea No. 1" to maximize its production potential [1][4]. - By 2025, the annual natural gas output of the gas field is expected to reach 5 billion cubic meters, surpassing the project's designed peak capacity [1][4]. - The operational time for oil exports has been reduced from 18 hours to under 8 hours, demonstrating significant improvements in operational efficiency [3][6]. - The "North Sea New Hope" shuttle tanker, specifically designed for "Deep Sea No. 1," has completed over 100 condensate oil export tasks, marking a significant advancement in deep-sea gas field operational management [3][6]. - The overall oil and gas production from the offshore gas fields around Hainan Island is projected to exceed 10 million tons of oil equivalent by 2025, doubling the output compared to the end of the 13th Five-Year Plan, with deep-sea oil and gas accounting for over 90% of the new production in the region [3][6].
