... suspension capabilities. The fluid can be decomposed with live and encapsulated oxidizer breakers to meet treatment design requirement. The fluid can be completely cleaned up and regained proppant pack conductivity was close to unity. Interesting fluid behavior was observed during large scale slot cell...

.... However, due to the tight shale formation, efficient proppant pack cleanup is critical to minimize polymer residue. The breaker systems include coated and uncoated oxidative breakers with an enzyme breaker added during the tail-in stages to break down the viscosity and aid in fracture fluid cleanup...

... the soluble particles disappear. Conductivity of the proppant pack was also determined. Two types of particle diverters (Diverter A and B) were tested. Diverter A is typically used for low- to medium-temperature application (less than 225°F) and Diverter B for high-temperature applications (greater than 225°F...
