After Offshore Oil 981 (hereinafter referred to as 981) successfully drilled its first deepwater development well in the South China Sea recently, the outside world is concerned about the role that the platform will play next.
Hong Kongs South China Morning Post reported yesterday (April 13) that the first deep-water development well platform in the South China Sea is planning to start the exploitation of liquefied natural gas (LNG) to provide energy to Guangdong, Hong Kong and Macao.
If LNG can be transported directly from CNOOCs terminal in Zhuhai to the Dawan District of Guangdong, Hong Kong and Macao through pipelines, it will reduce many transportation costs of energy companies and benefit local residents. The report quoted Han Xiaoping, chief information officer of China Energy Network, as saying.

China is narrowing the technological gap with Western countries
Observer Network reported earlier that 981 platform is the first deep-water semi-submersible drilling platform independently designed and built in China. The first deepwater development well drilled in the South China Sea recently is the first deepwater development well completed by the platform since it was put into operation in 2012. Previously, domestic deepwater development wells were completed by foreign deepwater drilling platforms.
This deepwater development well is located in the eastern waters of the South China Sea. It belongs to a directional well with high deviation. The drilling depth is 4660 meters and the vertical depth is 2529 meters.
China Offshore Petroleum Daily has pointed out that the industry calls the depth of 500 to 1500 meters deep water, 981 bored well 680 meters deep. In addition to the deep water, the well deviation is large and the horizontal displacement distance is long, which requires high accuracy of well trajectory.
In response, Han Xiaoping described the drilling success as breakthrough. According to the South China Morning Post, Han Xiaoping said the deepwater well was a technological breakthrough in China because it was a common drilling method in the United States, Britain and other Western countries.
The completion of this deepwater well shows that China is narrowing the gap with these Western countries. He said.
Clean energy must be available
CNOOC said Zhao Chunyan, manager of 981 platform, said that after the well was put into operation, the natural gas produced would be transported to Gaolan terminal in Zhuhai, Guangdong Province, to supply Guangdong, Hong Kong and Macao Dawan area.
The South China Morning Post pointed out that although the company did not mention when the drilling rig would start production, once production started, liquefied natural gas from the Deepwater development well would supply energy to 70 million people in Guangdong, Hong Kong and Macao.
According to the report, Dawan District of Guangdong, Hong Kong and Macao, including Hong Kong, Macao and nine cities in the Pearl River Delta (Guangzhou, Shenzhen, Zhuhai, Foshan, Huizhou, Dongguan, Zhongshan, Jiangmen and Zhaoqing), plans to build a comprehensive economic and commercial center.
Han Xiaoping believes that because the Bay Area is designed to rival Silicon Valley and Wall Street, it must have a reliable clean energy supply.
If LNG can be transported directly from CNOOCs terminal in Zhuhai to the Dawan District of Guangdong, Hong Kong and Macao through pipelines, it will reduce many transportation costs of energy companies and benefit local residents. He said.
