On the fracturing technology

in contrast to conventional hydraulic fracturing technology, several new waterless fracturing technology basic need of water, greatly ease the pressure on water resources. Especially for China so no perfect system of  Hydraulic fracturing  operations, and the lack of resources for countries waterless fracturing technology is likely to open the key  shale gas  resources in China.
Waterless fracturing technology introduction:
Compared with the conventional hydraulic fracturing technology, waterless fracturing technology mainly include nitrogen foam fracturing, carbon dioxide fracturing and LPG fracturing technology.
Anhydrous nitrogen foam fracturing technology in fracturing the formation fracturing technology has hurt small, low filtration,  Frac sand - carrying ability of the advantage, but only for use in water sensitive formations and shallow depth of wells.
Waterless fracturing technology of carbon dioxide fracturing technology anhydrous phase, will not cause water sensitive reservoir formation damage and no residue, do not support the reservoir and fracture permeability damage caused by debris, in addition to carbon dioxide fracturing energization with good role in the release of pressure, the carbon dioxide gas expansion, to achieve rapid flowback.
Anhydrous LPG fracturing technology in fracturing technology can provide producers with economic and environmental benefits of one of the rare technology breakthroughs. Using conventional  hydraulic fracturing  method, only a few back ground is safely discharged to the processing of up to 80% of the fracturing fluid left in the reservoir. Using liquefied petroleum gas fracturing technology allows the operator to use hydrocarbons have been produced to extract more hydrocarbons, but also not required in conventional fracturing biocides.
When the gel with our proprietary chemical reaction occurs, waterless fracturing technology provides a consistent viscosity, does not require the use of expensive CO2 or N2, does not require any special cooling or ventilation equipment. LPG fracturing technology for rich byproduct gas industry is also easy to storage at ambient temperature. Using liquefied petroleum gas fracturing technology also reduces the combustion process than conventional fracturing fluid cleaner, while reducing carbon dioxide emissions.
Currently waterless fracturing technology including the above three fracturing technology, but there are some technical operations immaturity, if not professional waterless fracturing technology operating personnel, the general recommendation to use hydraulic fracturing wells.
