Patent number: 7798224Abstract: A method of treating a subterranean formation penetrated by a wellbore includes preparing a treatment fluid with shear thinning, non-monotonic rheological properties, injecting the treatment fluid into the subterranean formation, and inducing shear rate softening phase transition in the treatment fluid. The non-monotonic rheology properties can be such that in the relationship between shear stress (?) versus strain rate ({dot over (?)}), where {dot over (?)}1<{dot over (?)}2<{dot over (?)}3<{dot over (?)}4, the shear stress values are ?1<?2?3??4, and ?3<?2 The method can heterogeneously deposit proppant or solid acid in a fracture. A system to fracture a subterranean formation includes the fracturing fluid, a wellbore to inject the fracturing fluid to propagate a fracture in the formation, and a rate controller to inject the fracturing fluid into the subterranean formation at a minimum volumetric rate to provide a shear stress at an inlet to the fracture that exceeds ?2.Type: GrantFiled: June 27, 2007Date of Patent: September 21, 2010Assignee: Schlumberger Technology CorporationInventors: Haiying Huang, Joseph A.
