Ammonium Persulfate Fracturing Fluid Gel Breaker
CAS Number: 7727-54-0
Ammonium persulfate is an oxidative gel breaker used to degrade guar gum and HPG fracturing gels after proppant placement, enabling rapid flowback of broken fluid and cleanup of the fractured formation. It generates free radicals upon thermal activation that cleave polysaccharide chain bonds, reducing gel viscosity below 5 cP for effective cleanup. Typical dosage is 1–10 lb/Mgal depending on gel loading and bottom-hole temperature.
