China's Deep Sea No.1 offshore gas field just flexed its energy muscles 💪, producing over 4.5 million tonnes of oil equivalent in 2025 – a milestone announced by the China National Offshore Oil Corporation (CNOOC) this week. The field, operating in waters deeper than 1,500 meters, is now powering homes and industries with 15 million cubic meters of natural gas daily.
Phase two of this engineering marvel (completed last year) tackled extreme pressures and temperatures – think 'Mariana Trench meets industrial ambition' 🌡️. CNOOC engineers called it China's 'most challenging deepwater project to date,' pushing tech boundaries while boosting clean energy output.
Fun fact: This single offshore field now matches the output of a medium-sized onshore oilfield 🏞️→🌊. With condensate oil production hitting 1,600 tonnes daily, Deep Sea No.1 is fueling China's energy transition – and showing how deep the future of sustainable power lies.
