Patent number: 8575073Abstract: A treatment fluid for treating a subterranean formation penetrated by a wellbore is formed from water, a polyacrylamide in an amount of less than about 0.5% by weight of the fluid for reducing friction of the fluid and a stabilized peroxide breaker. A method of treating a subterranean formation penetrated by a wellbore is carried out by forming treatment fluid comprising water, a polyacrylamide in an amount of less than about 0.5% by weight of the fluid for reducing friction of the fluid and a stabilized peroxide breaker. The treatment fluid is introduced into the formation through the wellbore at a pressure above the fracture pressure of the formation.Type: GrantFiled: June 20, 2008Date of Patent: November 5, 2013Assignee: Schlumberger Technology CorporationInventors: Syed Ali, Leiming Li, Lijun Lin, Paul R. Howard, Curtis L. Boney, Carlos Abad
