The development covers the main area of Kenli 6-1, China’s first large-scale shallow lithological oilfield project, CNOOC said, with reserves of 100 MM t in the Laibei lower uplift.
Facilities include six standardized unmanned platforms connected to one central platform.
The company plans to drill 67 production wells, 36 water injectors and four water source wells, with peak oil production of about 36,100 bbl/d in 2024.
In addition, CNOOC has started up its Bozhong- Kenli oilfields onshore power project in Bohai Bay, comprising four offshore electric power platforms and one onshore high-voltage substation.
The 520-MW power transmission system will supply electricity to 39 offshore production platforms serving the Kenli oil fields, Bozhong 19-6 condensate gas fields and Bozhong 28-34 oilfields.
By 2025, the project should support production of about 400,000 bbl/d in the region.
The facilities should conserve about 53 MMcf of gas and cut nitrogen oxide emissions by 14,700 metric tons and CO2 emissions by 1 MM metric tons during a peak electricity consumption year, CNOOC claimed.
