Core Viewpoint - The successful production launch of the Kenli 10-2 oilfield group marks a significant milestone for China's offshore oil development, particularly in the complex heavy oil reservoir sector [2][3]. Group 1: Project Overview - The Kenli 10-2 oilfield group is located in the southern Bohai Sea with an average water depth of approximately 20 meters, utilizing existing facilities for development [3]. - The project plans to develop 79 wells, including 33 cold production wells, 24 thermal production wells, 21 water injection wells, and 1 water source well, aiming for a peak production of approximately 19,400 barrels of oil equivalent per day by 2026 [3]. Group 2: Technological Innovations - The oilfield features a unique "conventional water injection + steam flooding + steam drive" joint development approach, addressing the challenges posed by the reservoir's "scattered, narrow, thin, and mixed" characteristics [4]. - The project platform integrates both conventional cold production and thermal production systems, making it one of the most complex production platforms in the Bohai region [4]. - The company has achieved significant breakthroughs in drilling and completion engineering, including the large-scale application of self-developed high-temperature electric submersible pump technology, enhancing production efficiency [4]. Group 3: Future Capital Expenditure and Production Goals - The company plans to maintain high capital expenditures, with a budget of 125 to 135 billion yuan for 2025, focusing on exploration, development, and production [5]. - The production target for 2025 is set at 760 to 780 million barrels of oil equivalent, reflecting a year-on-year growth of 5.9%, with subsequent years showing stable growth rates [5].
