摘要： A method of fracturing a production interval of a subterranean formation adjacent a wellbore that is open hole or has an uncemented liner is provided. The method comprises the steps of: (a) perforating a zone of the production interval by injecting a pressurized fluid through a hydrajetting tool into the subterranean formation, so as to form one or more perforation tunnels; and (b) injecting a fracturing fluid into the one or more perforation tunnels so as to create at least one fracture along each of the one or more perforation tunnels; wherein at least a portion of at least one of the pressurized fluid and the fracturing fluid comprises a viscoelastic surfactant fluid. According to another aspect, a method of fracturing a production interval of a subterranean formation adjacent a wellbore that is open hole or has an uncemented liner is provided, wherein the method comprises the steps of: (a) perforating a zone of the production interval by injecting a pressurized fluid through a hydrajetting tool into the subterranean formation, so as to form one or more perforation tunnels; (b) injecting a fracturing fluid into the one or more perforation tunnels so as to create at least one fracture along each of the one or more perforation tunnels; and (c) plugging at least partially the one or more fractures in the zone with an isolation fluid; wherein at least a portion of at least one of the pressurized fluid, the fracturing fluid, and the isolation fluid comprises a viscoelastic surfactant fluid.
