China is eyeing extra abroad alternatives for its offshore drilling and completion applied sciences at high-temperature and high-pressure fuel fields, in response to the nation's largest producer of offshore oil and fuel, China National Offshore Oil Corp.

China's technological capability to independently develop high-temperature and high-pressure fuel fields is barely second to that of the United States, stated Li Zhong, chief engineer of CNOOC's Zhanjiang department.

The know-how and innovation being deployed within the South China Sea, which was granted first prize on this yr's National Science and Technology Awards, has been efficiently utilized to the HTHP fuel fields at house and overseas, together with eight HTHP fuel fields within the Gulf of Mexico, seven in Europe's North Sea and 18 in Iraq, stated Li Yanjun, chief govt engineer of HTHP drilling and completion of CNOOC's Zhanjiang department.


According to the Ministry of Land and Resources, practically 15 trillion metric tons of pure fuel lies there, one-third of the overall within the South China Sea.

However, temperatures on the seabed stratum can attain 249 C, whereas the strain there’s equal to placing 125,000 tons on a floor of 1 sq. meter, each of which current distinctive challenges to grease and repair firms.

“Drilling and finishing a properly at deep water is not any simple job,” stated Li Yanjun.

“One of the harshest environments within the business, the South China Sea's unstable situations embody battering from the wind, chilly temperatures, fixed moisture from storms and mist from the excessive winds.”

This atmosphere makes the South China Sea one of the vital demanding of all offshore oil and fuel exploration territories, together with the North Sea and the Gulf of Mexico.

Six worldwide petroleum firms got here to China again within the 1980s in an try to beat technical difficulties, solely to finish up yielding little or no after an enormous spending.

Backed by the National High-tech R&D Program and within the framework of a National Science and Technology Major Project, CNOOC has been conducting its personal exploration because the 1990s. After 20 years of analysis, CNOOC Zhanjiang Branch has reduce the typical drilling interval from 175 days to 52 days, and decreased prices by 70 p.c.

The know-how, which allows fuel exploration to penetrate the onerous seabed to achieve fuel beneath scalding rock formations, has generated direct income of 21.6 billion yuan ($three.four billion) and oblique income of 356.5 billion yuan previously seven years since its utility, whereas considerably enhancing effectivity and safety, stated Li Yanjun.

“We are assured the know-how will probably be utilized to extra HTHP fuel fields house and overseas to assist increase effectivity and additional faucet the potential of deep sea vitality.”
