Group 1 - "Deep Sea No. 1" has completed the export of over 650,000 tons of condensate oil, with annual oil and gas output exceeding 4.5 million tons of oil equivalent for the first time [3]. - The gas field is China's deepest and most challenging deep-water gas field, with the highest geological temperature and pressure, and the largest annual gas output since its commissioning in 2021 [3][5]. - The gas field has a proven geological natural gas reserve of over 150 billion cubic meters and is developed in two phases, featuring core production facilities capable of processing and separating oil and gas offshore [5]. Group 2 - The gas field operates at a maximum working depth of over 1,500 meters and a maximum geological temperature of 138 degrees Celsius, with a current natural gas production capacity of 5 billion cubic meters per year [5]. - Daily production includes 15 million cubic meters of natural gas and over 1,600 tons of condensate oil, with a cumulative production of nearly 14 million tons of oil equivalent since its launch [5].
