Imagine an offshore platform pumping deep beneath the waves – that’s the scene at the Bohai Oilfield. This year, the Chinese mainland’s largest offshore oilfield pumped out over 40 million tonnes of oil equivalent, the China National Offshore Oil Corporation (CNOOC) announced on December 21, 2025.
Spanning more than 60 producing oil and gas fields, the Bohai Oilfield has now delivered a cumulative 600 million tonnes of crude since operations began. Over the past five years, its output grew by an average of 5 percent annually, reflecting steady gains in efficiency and scale.
CNOOC credits part of this success to digital and green transformations. Breakthroughs in localizing crucial equipment include the Chinese mainland’s first domestically developed shallow-water subsea production system. Onshore power connections now supply over 80 percent of the field’s platforms, cutting emissions and fuel costs.
Beyond numbers, this record output underlines a broader push for energy security and sustainable growth. As global markets navigate shifting demand and decarbonization targets, innovations from the Bohai Oilfield offer a glimpse of how offshore operations can evolve.
Looking ahead, CNOOC plans to deepen digital systems and expand green practices, aiming to balance performance with environmental stewardship. For young professionals, entrepreneurs, and renewable advocates, the Bohai model highlights how technology and sustainability can drive the future of energy.
