Heres a writeup on Chinese ultra deepwater oil technology.
"Chinese energy experts say Beijing will eventually move its first ultra-deepwater rig to explore in deeper and more oil-rich waters further south in the South China Sea, where China, Vietnam, the Philippines, Taiwan, Malaysia and Brunei have overlapping territorial claims
China has spent nearly USD 1 billion on an ultra-deepwater rig that appears intended to explore disputed areas of the South China Sea, according to reports.
The area is one of Asia's most volatile hotspots and where the US is strengthening ties with Beijing's rival claimants.
For now, the locally built Haiyang Shiyou (Offshore Oil) 981 rig owned by China's state-run CNOOC oil company is drilling south of Hong Kong in an area within Beijing's ambit.
"With Chinese offshore drilling technology improving, it is just a matter of time for them to enter the central and southern part of the South China Sea," said Liu Feng, senior researcher at the state-backed National Institute for South China Sea Studies."
