Investment Rating - Investment recommendation: Outperform the market (maintained) [8] Core Viewpoints - The report emphasizes the significant potential of deep-sea oil and gas resources in China, particularly in the South China Sea, where there are abundant untapped mineral resources. The report highlights that CNOOC is the largest offshore oil and gas operator in China, with a comprehensive industrial chain covering exploration, engineering construction, equipment operation, and oilfield services. The deep-sea economic strategy is expected to enhance the value of CNOOC and related marine oil and gas service industries [10][19]. - The report identifies three key barriers in the deep-sea sector: the increasing demand for high-performance and specialized chemical materials in extreme marine environments, the corrosion challenges faced by marine engineering, and the anticipated growth in demand for sealing materials driven by the marine economy [11][12][13]. Summary by Sections 1. Marine Resource Endowment and CNOOC's Leadership - The report discusses the importance of the Central Economic Committee's meeting on July 1, 2025, which focused on promoting high-quality development of the marine economy and enhancing marine resource development capabilities. It is expected that supportive policies will accelerate the development of deep-sea technology, equipment manufacturing, and material applications [3][18]. - CNOOC is positioned as a key player in China's deep-sea energy security strategy, with significant oil and gas reserves in the South China Sea, estimated at approximately 3.6 billion barrels of oil and 40.3 trillion cubic feet of natural gas [19][22]. 2. Demand for High-Performance and Specialized Chemical Materials - The report highlights the growing market demand for marine new materials, which are essential for modern marine economic development. These materials are crucial for various applications, including naval equipment, shipbuilding, marine engineering, and resource development [81]. - The report notes that the marine engineering sector faces severe corrosion challenges, necessitating advanced anti-corrosion technologies and materials to ensure the safety and economic efficiency of marine equipment [86][87]. 3. Investment Recommendations - The report suggests focusing on leading central enterprises in deep-sea oil and gas exploration and extraction, particularly CNOOC, as well as the marine oil and gas service industry. Additionally, it recommends paying attention to high-performance anti-corrosion coatings and sealing materials due to their critical demand in extreme marine environments [14].
