“We are seeing clear signs of increasing interest for broadband acquisition in Chinese waters” – CEO CGGVeritas

A French-based geophysical services company has used its technology to complete 3D marine surveys offshore China, it emerged on Wednesday, as the country shows signs of increasing demand for broadband acquisition in its waters.

CGGVeritas has used its BroadSeis marine broadband tool to finish deepwater surveys of two areas offshore Shenzen in the east of the South China Sea, where China has moved into ultra-deepwater exploration.  The surveys were commissioned by CNOOC subsidiary Chinese seismic services company China Oilfield Services Limited (COSL).

The geophysical services company acquired approximately 1,000 sq km full-fold data over the two survey areas. Data processing is expected to be delivered by the end of 2012, CGGVeritas said.

Broadband acquisition improves the quality of geophysical interpretation and the imaging of deep features. According to CGGVeritas, BroadSeis is able to record and process six octaves of data, including ultra-low frequencies in the 2.5 - 5 Hz range, enhancing penetration and illumination below complex overburdens such as subsalt and sub-basalt environments.

“Successful cooperation between COSL and CGGVeritas within this project… services the client with high technology and quality at a competitive cost and makes significant contributions to the advancement of geophysical technology,” said Yang Jing Hong, President of COSL Geo.

Jean-Georges Malcor, CEO, CGGVeritas, highlighted: “We are seeing clear signs of increasing interest for broadband acquisition in Chinese waters.”

China’s third largest oil company, CNOOC led the development of China's first three LNG import terminals at Shenzhen, Fujian, and Shanghai and manages much of the country's offshore production. In July it won government approval to build a second liquefied natural gas (LNG) terminal in Shenzhen, which will have a receiving capacity of 4.0 million tonnes per year.

China, the world's top energy user, is operating five LNG terminals along its coast to import the super-chilled natural gas, and is planning 12 other such facilities to feed its economic growth.
