China's largest offshore shallow lithologic oilfield fully operational

China's largest offshore shallow lithologic oilfield, the Kenli 10-2 oilfield cluster, has entered full production in its first phase of its development project, with daily crude oil output surpassing 2,800 tonnes, the China National Offshore Oil Corporation (CNOOC) announced on Wednesday.

The Kenli 10-2 oilfield, located in the southern waters of the Bohai Sea with an average water depth of approximately 20 meters, is the largest lithologic oilfield discovered in China's offshore waters, with proven geological reserves exceeding 100 million tonnes.

The oilfield is considered a key asset of the Bohai oilfield – China's largest crude production base – providing substantial support for stable output and further growth.

The first phase of development includes one newly built central processing platform and two unmanned wellhead platforms, with a total of 79 development wells drilled.

The oil and gas are primarily stored in narrow, curved sand bodies that intertwine like crisscrossing tree shadows on the ground, forming a typical "branching" morphology. The project marks the first offshore development of a dendritic heavy oil reservoir in China.
