摘要： A method for increasing the rate of shear rehealing of fluids made with cationic, zwitterionic, and amphoteric viscoelastic surfactant fluid systems by adding an effective amount of a polymeric rheology enhancer selected from polypropylene glycols and block copolymers of polypropylene glycol and polyethylene glycol. For applications in which rapid shear rehealing is required, the rheology enhancer allows fluids to be made and used at lower viscoelastic surfactant concentrations. Preferred surfactants are betaines and quaternary amines. The fluids are useful in oilfield treatments, for example fracturing and gravel packing.

摘要： Methods and compositions are disclosed for controlled addition of components that decrease the viscosity of the viscoelastic surfactant fluids or for controlled changes in the electrolyte concentration or composition of the viscoelastic surfactant fluids. One aspect of the invention relates to the use of internal breakers with a delayed activation. Another aspect of the invention relates to the use of precursors that release a breaking system such as alcohol by a process such as melting, slow dissolution, reaction with a compound present in the fluid or added to the fluid during or after the step of injecting, rupture of an encapsulating coating and de-adsorption of a breaking agent absorbed into solid particles. In another aspect of the invention, alcohols are included in a pad to reduce the low-shear viscosity and reduce the resistance to flow of the treatment fluids during a desired phase of the treatment.

摘要： A viscoelastic gelled oil, for example gelled diesel or paraffin oil, is made with a gelling agent, for example a phosphate ester, a metal carboxylate, for example an aluminum carboxylate, and a gel-enhancing surfactant, for example a zwitterionic surfactant, for example erucylamidopropyl betaine. The gel-enhancing surfactant makes the gel viscoelastic, increases the stability and decreases the sensitivity to the concentrations of the gelling agent and the metal carboxylate. The enhanced viscoelastic gelled oils are used, as examples, in hydraulic fracturing, frac packing, gravel packing, diversion, fluid loss control, lost circulation control, sand control, wellbore cleanout, wellbore or pipeline sweeping, organic scale dissolution, organic scale removal, and drilling.

摘要： A switching matrix and testing platform may enable controlled testing of various configurations of radio access networks (RANs) at various signal strengths. The switching matrix and testing platform may enable testing of the radio frequency (RF) signals from RANs or telecommunications devices for new and/or predetermined scenarios, such as using different configurations of the RANs at various signal strengths. During a scenario, various operations may be performed on the telecommunications device in communication with the tested RF signals, such as making voice calls, transmitting and receiving data (messages, videos, music, etc.). A performance of the telecommunications device and/or various telecommunication network elements may be analyzed in comparison to other telecommunications device and/or various telecommunication network elements.
