Abstract: A technique facilitates a well treatment, such as a well stimulation. The technique comprises injecting a gel containing proppant into a wellbore extending into a subterranean formation. Additionally, a low viscosity fluid is injected into the wellbore with the gel either simultaneously or separately. An additive or additives may be used to maintain the gel in the low viscosity fluid. The technique further comprises separating the gel into slugs and then causing the slugs to flow into fractures in the subterranean formation.

Abstract: Services and applications running on devices placed in live wireless environments are tested and reported to determine the relative performance of the device under test. Multiple logs collected from the device under test are combined and transmitted to a remote backend system. The backend system stores and analyzes the combined logs to generate reports containing factual and relative performance information regarding the device during the testing period. The nature of the test, the collected log information, and the report format may all be modified according to the criteria of the requestor.

Abstract: A wellbore cleaning device comprises a tubular section, a helical scratcher mounted thereon. The helical scratcher contains flexible wires characterized in that the helical scratcher is able to rotate axially to the tubular section when a fluid flows axially to the tubular section. A method for using the device comprises placing the device into the wellbore; allowing the fluid flowing axially to the wellbore wall to rotate the scratcher; removing a deposit at wellbore wall; and leaving a cleaned wellbore wall.

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: Techniques for calculating quality of user experience (QoE) scores for video streams as played on receiving devices are described herein. Prior to calculating a QoE score, a device receives a video of a display screen of a receiving device captured while the receiving device plays a video stream. The device also receives transmission metrics from at least one device engaged in the transmission of the video stream to the receiving device. The device then calculates the QoE score for that received video based at least in part on a reference video, the transmission metrics, and one or more QoE models. Additionally, prior to receiving the video or the transmission metrics, the device may automate the transmission of the reference video as the video stream from a sending device to the receiving device over at least one network emulator, including providing network impairment settings to the network emulator.

Abstract: A method and apparatus for treating a subterranean formation traversed by a wellbore including forming an emulsion comprising oil, acid, and particulate, wherein the forming the emulsion is prepared on the fly, and introducing the emulsion into a wellbore.

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 composition and method is given for a well control fluid that is injected into a well during completion or remediation and prevents fluid flow from a formation into the well during operations (such as shut-in, or placement or adjustment of tools/hardware) when no fluid flow is desired. The composition includes a viscoelastic surfactant fluid system (VES) and a decomposable first solid material, preferably in fiber form, that forms a pack or plug in the well at the location where fluid would otherwise leak off, and then decomposes without intervention to release a product that is a breaker for the surfactant or the micelles of the VES. The composition optionally also contains a pH control agent and a second solid (that may also be a fluid loss agent) that affect the decomposition of the first solid.

Abstract: A composition for treatment of a subterranean formation, which may be used for water control, is comprised of at least one of 1) a premix of an oleochemical polyol, at least one of polyisocyanate, polycyanate and polyisothiocyanate, and a blocking agent to temporarily block all or a portion of free reactive groups of said at least one of polyisocyanate, polycyanate and polyisothiocyanate. Alternatively, or in addition, the composition may be comprised of a solvent and 2) a polyurethane prepolymer formed by reacting an oleochemical polyol and at least one of polyisocyanate, polycyanate and polyisothiocyanate. A blocking agent may also be used with the polyurethane prepolymer. The composition may be used in a method of treating a subterranean formation penetrated by a wellbore by introducing the composition into the formation through the wellbore.

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 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.
