Environmentally Friendly: No oil phase, flow back fluid easy to handle and low treatment cost.


Low Cost: Usage is reduced by 40-60%, Fracturing fluid costs decreased by more than 10%.


Low Damage: Low molecular weight polymer modification, less residues, core permeability damage rate is 30-50% less.


High Salinity Resistance: 5 times higher than that of conventional emulsion, which can achieve the reuse of flowback water and further reduce the operation cost.


High Level Of Automation: On-fly mixing, precise automatic dosing control, liquid viscosity can be adjusted in real time, to achieve the dry powder fracturing fluid supply, distribution and injection.


Low QHSE Risks: Reduce transportation, storage risks, non-leakage contamination.
Providing operation plan, materials, equipment and on-site implementation of integrated technical services.


Reducing cost and increasing efficiency of large-scale fracturing operations in tight oil and gas, shale oil and gas, coalbed methane and other reservoirs.
Case Study 1 – Ordos Basin Deep Extra-low Porosity / Permeability Tight Sandstone Gas Reservoir


Formation depth is 2,755m; logging porosity of 9-14% and permeability of 0.6-1.6 mD;


Minor-small throat size;formation pressure co-efficient is 0.95, temperature is 110℃;


All performances meet or exceed the design requirements;


the usage decreases by 40-50% (0.35-0.4% ratio to achieve 72-87 mPa.s while conventional fluid ratio was 7%),max sand ratio was 30% at 37 - 44 bpm pumping rate; friction reduction rate 75%;


Fracture half length is around 656 ft from real-time monitoring and simulation, which meet the design requirement;


Stable gas production 1,732,538 scf/d (5mm Nozzle) , estimated AOF around 2,472,000 scf/d, which was 3 times of adjacent wells;


Cost reduction was more than 10% compared with the conventional fracturing fluid system.
