Shell hopes to thoroughly study the China's geology by the end of 2014 or early next year, when Shell and China National Petroleum Corp will decide what the next steps are.

Although the chairman did not specify how much Shell wants to invest, the company had previously said it would to spend USD 1 billion every year from March 2013 in developing the country’s shale gas reserves. Shell secured China’s first shale gas product sharing contract in March 2013 to develop the Sichuan block.China’s aim is to produce 6.5 billion cubic meters by 2015 and it believes it is on track for this, particularly because of better than expected results from its Fuling block.

And the oil based drilling mud are popular for developing the shale gas. And from 2012, the environmental regulations for China's government have changed. All the oil based drilling cuttings should be treated to meet the standard.The standard requires the oil on the cuttings to be below 1%. So we can see, there is a huge market in Sichuan for the oil based drilling cuttings treatment business.

GNLW363BG-VFD Decanter Centrifuge can be run at different bowl speeds with different G force. If the operator wants to separate high gravity solids, the recommended speed is around 2200 RPM. If the operator wants to separate low gravity solids, the 3200RPM high speed should be applied. For the drilling fluids discharged from the cuttings dryer, normally, 2700RPM is recommended for the operation.

The drilling cutting is transferred by two screw conveyors to the vertical cuttings dryer. The cuttings dryer recover oil from the drilling cuttings for resuse.The oil recovered is feed to the variable speed decanter centrifuge for cleaning solids in the oil, after cleaning, the oil can be used for drilling mud system again.
