China's shale gas development will bring business opportunities to the related equipment manufacturing industry with a market value of about 3 billion yuan ($477 million) this year, a 33 percent growth compared with last year, industrial insiders said.

The second round of tenders for China's shale gas blocks was held last year, leading to increasing demand for fracturing equipment in the second half of this year, said Zhang Guoyou, general manager of the domestic sales department of SJ Petroleum Machinery Co under State-owned Sinopec Group, the country's largest oil and gas refiner.

According to China's 12th Five-Year Plan (2011-15) on energy industry, the country will realize large-scale commercialized production of shale gas by 2015.

To meet the target of 6.5 million cubic meters of production capacity by 2015, China is accelerating its pace in surveying and exploring the unconventional energy source. Experts said the main obstacle is the technology barrier during exploration.

However, equipment manufacturing companies have achieved some progress.

Zhang said the company will invest 1.1 billion yuan on research for shale gas exploration equipment during the 12th Five-Year Plan.

The company has sold 20 fracturing equipment units, and four units were ordered and will be delivered over the next two months, Zhang said.

Fracturing equipment is the core machine for shale gas exploration, accounting for more than 65 percent of all equipment needed for its production.

Having more shale gas reserves than the United States, China has created a huge market for the related equipment manufacturing industry, said Jiang Xiaobao, vice-president of Yantai Jereh Oilfield Services Group Co, a private oil and gas services company, which owns about half of the domestic shale gas equipment market share.

The US has an annual demand for fracturing equipment of about 800 units for the shale gas industry, which means China will have a similar demand if it wants to develop to the same scale as the US, Jiang said.

China bought 200 units of fracturing equipment in 2012, twice the amount in 2011. Demand will definitely soar this year, Jiang said.

"China has very different shale exploration conditions compared with the US, which requires that the equipment can be operated in mountain areas with a bad geological environment," Jiang said. "We are developing such equipment that fits China."
