    Abstract: Particles are provided in which proppant and gravel used in treating subterranean wellbores are coated with most or all of the chemical components needed to make the carrier fluids used to deliver them. The components come off the proppant or gravel during injection and viscosify the fluid. Components may be applied in layers, as uniform or non-uniform mixtures, or both. Particle coatings may include gas pockets that reduce the particle density.

    Abstract: 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.

    Abstract: Water-soluble amphoteric surfactants at low concentration thermostabilize enzymes in brine. The thermostabilized enzyme compositions can be used in a method to digest polymers at temperatures and/or salinities at which the enzyme is normally inactivated and/or coagulated without the surfactant. In oilfield applications, the composition can be used in well treatment methods including filtercake removal and polymer viscosity breaking in well treatment fluids.

    Abstract: A fluid-loss pill that includes a brine solution and an effective amount of a viscoelastic surfactant is disclosed. The viscoelastic surfactant preferably includes at least one compound selected from the family of compounds described by where R1, R2, R3, R4 and R5 are carbon atom or carbon chains, saturated or unsaturated, single or multiple unsaturation, straight chain, branched chain or cyclic including aromatic or alicyclic groups, and R1 contains 16-26 carbon atoms, R2 contains 2-10 carbon atoms, R3, R4 and R5 contains 1-6 carbon atoms. Methods of treating a well that include injecting fluid-loss pill into a well to control lost-circulation or to kill a well.

    Abstract: 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.
