Platform conductor integrity management in life extension of ageing offshore wells
The increase in ageing offshore wells in most of the oilfields in the South China Sea, with their assets exceeding their design life is a challenge faced by operators worldwide. Severe corrosions on the metallic structures of oil wells consisting of the conductor and casings can result in catastroph...

The increase in ageing offshore wells in most of the oilfields in the South China Sea, with their assets exceeding their design life is a challenge faced by operators worldwide.
