UZP-160A Thickener
Product introduction
UZP-160A is designed for oilfield fracturing operation, is used in conjunction with crosslinking agent UZP-160B to form a novel clean fracturing fluid system. The system has super temperature and salt resistance, suitable for the conventional fracturing operation of oil and gas wells between 60ºC and 160ºC, especially has remarkable effects on the wells beyond 120ºC. This system can be used with on-site flowback water, and the effect will be not affected. UZP-160A also can be used as drag reducer.

Application
- The dosage of UZP-160A is measured according to the concentration of the mixture, stir in the agitator for 300-400r/min, it will take 30 minuts from dissolve thoroughly to form a uniform solution, and the base fluid viscosity getting stable.
- The crosslinking time can be adjusted, and the adjustment range is 0 ~ 2 minutes.
- The breaking time of the system can be adjusted according to the actual situation (the minimum dosage of the breaking agent is 0.05%)
All personnel handling this material must handle it as an industrial chemical, wearing protective equipment and observing the precautions as described in the Material Safety Data Sheet.
Packaging and Storage
UZP-160A is packed in 25kg woven bag or kraft paper barrel.
UZP-160B is packed in 200L plastic drum.
Store in dry, well-ventilated area. Keep container closed. Keep away from heat, sparks and flames. Store away from incompatibles. Follow safe warehousing practices regarding palletizing, banding, shrink-wrapping and /or stacking. Shelf life is 12 months.
