Core Viewpoint - The intrinsic value of CNOOC is composed of several components, including PV-10 value of proven reserves, discounted value of proven but unconfirmed reserves, increased value from enhanced oil recovery in old oil fields, value of exploration and extraction rights in domestic offshore areas, and net cash on the balance sheet [2][3]. Summary by Sections - Under the assumption of an average Brent crude oil price of $82 in 2023, CNOOC's PV-10 value is approximately 882.1 billion yuan, corresponding to proven reserves of about 678 million barrels. For 2024, with an average Brent price of $80, the proven reserves are estimated at 732 million barrels, with a discounted value of around 960 billion yuan [2][3]. - By the end of 2024, CNOOC's proven but unconfirmed reserves are estimated at 750 million barrels, with a barrel oil discounted value of approximately $12, leading to a total discounted value of about 640 billion yuan [3]. - The increased value from enhanced oil recovery in old oil fields is estimated at around 150 billion yuan.
