Core Viewpoint - China National Offshore Oil Corporation (CNOOC) announced that the "Deep Sea No. 1" gas field has completed its 100th oil export since production began, with total oil and gas output expected to exceed 4.5 million tons of oil equivalent by 2025, comparable to that of a medium-sized onshore oil field, showcasing advanced production and operation technology in China's deep-sea gas fields [1][4]. 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].

Core Insights - China National Offshore Oil Corporation (CNOOC) announced the completion of the 100th oil export from the "Deep Sea No. 1" gas field, marking a significant milestone in China's offshore oil production capabilities [1][2] - The gas field is projected to exceed a total oil and gas production of 4.5 million tons of oil equivalent by 2025, showcasing advanced production and operational technology [1] Group 1: Production and Capacity - "Deep Sea No. 1" is China's largest offshore gas field, characterized by the deepest operational water depth, highest formation temperature and pressure, and the greatest exploration and development challenges [1] - The gas field has a maximum operational water depth of over 1,500 meters and a geological natural gas reserve of over 150 billion cubic meters [1] - Daily production from the gas field includes 15 million cubic meters of natural gas and over 1,600 tons of condensate oil [2] Group 2: Technological Advancements - CNOOC has established a complete technical system for the production and operation of ultra-deepwater gas fields, reducing the time for oil tanker export operations from 18 hours to less than 8 hours [1] - The core production facilities, including the "Deep Sea No. 1" energy station and the "Four Stars in a Row" platform group, are capable of processing and separating natural gas and crude oil on-site [1]

Core Insights - China's largest offshore gas field "Deep Sea No. 1" has completed its 100th oil export operation since production began, with an expected annual output of over 4.5 million tons of oil equivalent by 2025, comparable to that of a medium-sized onshore oil field, indicating that China's deep-sea gas field production and operation technology has reached world-class standards [1][7]. Production and Export Operations - "Deep Sea No. 1" produces 5 billion cubic meters of natural gas annually, along with over 400,000 tons of condensate oil as a byproduct [7]. - The condensate oil is stored in four pillars surrounding the platform, each equipped with a storage capacity of 5,000 cubic meters [7]. - The oil is temporarily stored in the pillars and then transported via a shuttle tanker to onshore refineries for further processing [7]. Export Logistics - The condensate oil export hose measures 220 meters in length, with a maximum export capacity of nearly 15,000 tons, and exports occur approximately every 12 days [9]. - The project team employs a shuttle tanker equipped with an advanced dynamic positioning system to ensure safe oil transport in complex sea conditions [11]. Technological Advancements - The "Beihai New Hope" shuttle tanker, designed specifically for the "Deep Sea No. 1" project, is the first domestic dynamic positioning shuttle tanker, measuring 137 meters in length and capable of carrying up to 15,000 tons [13][15]. - This vessel represents a breakthrough in China's capabilities in the design, construction, and operation of high-end special vessels, previously dominated by foreign companies [15]. Industry Impact - The successful construction and operation of the "Beihai New Hope" has enabled China to master core technologies related to dynamic positioning shuttle systems, which will facilitate the application of these technologies in domestic deep-water oil and gas projects and promote Chinese enterprises and technologies in the international market [17].
