Hydraulic fracturing is an effective technique for increasing the productivity of wells producing from low permeability formations. Tracer fracture monitoring technique is near-wellbore zone frctures direct test method that can monitor the height and width of hydraulic fractures in the near-wellbore section. ZeroWash Tracer uses a medium strength ceramic proppant which is mainly used in fracturing process. It can make three different energy levels of tracer into the fracturing fluid and pump into formation, to monitor wellbore proppant distribution and identify fracture height. The application of ZeroWash Tracer in Changqing oilfield has been a great success. ZeroWash Tracer is used to monitor wellbore proppant distribution and evaluate fracturing effects in Hydraulic Fracturing.
