Abstract: A wirelessly controlled active inflow control valve system. The valve system includes at least one downhole zonal production control unit. The at least one zonal production control unit includes a valve configured to control an inflow of fluid, at least one sensor configured to sense at least one parameter, and a central downhole control and data acquisition unit communicatively coupled to the valve and the at least one sensor. The central downhole control and data acquisition unit sends an actuation signal to the valve and receives at least one data output from the at least one sensor. The central downhole control and data acquisition unit transmits the at least one data output to a surface control and data acquisition unit via a wireless communication protocol and receives a control command from the surface downhole control and data acquisition unit via the wireless communication protocol.

Abstract: Double-layer capacitors capable of operating at extremely low temperatures (e.g., as low as ?80° C.) are disclosed. Electrolyte solutions combining a base solvent (e.g., acetonitrile) and a cosolvent are employed to lower the melting point of the base electrolyte. Example cosolvents include methyl formate, ethyl acetate, methyl acetate, propionitrile, butyronitrile, and 1,3-dioxolane. A quaternary ammonium salt including at least one of triethylmethylammonium tetrafluoroborate (TEMATFB) and spiro-(1,1?)-bipyrrolidium tetrafluoroborate (SBPBF4), is used in an optimized concentration (e.g., 0.10 M to 0.75 M), dissolved into the electrolyte solution. Conventional device form factors and structural elements (e.g., porous carbon electrodes and a polyethylene separator) may be employed.

Abstract: Double-layer capacitors capable of operating at extremely low temperatures (e.g., as low as ?75° C.) are disclosed. Electrolyte solutions combining a base solvent (e.g., acetonitrile) and a cosolvent are employed to lower the melting point of the base electrolyte. Example cosolvents include methyl formate, ethyl acetate, methyl acetate, propionitrile, butyronitrile, and 1,3-dioxolane. An optimized concentration (e.g., 0.10 M to 0.75 M) of salt, such as tetraethylammonium tetrafluoroborate, is dissolved into the electrolyte solution. In some cases (e.g., 1,3-dioxolane cosolvent) additives, such as 2% by volume triethylamine, may be included in the solvent mixture to prevent polymerization of the solution. Conventional device form factors and structural elements (e.g., porous carbon electrodes and a polyethylene separator) may be employed.

Abstract: A thermoelectric power generation device using molybdenum metallization to a Zintl thermoelectric material in a thermoelectric power generation device operating at high temperature, e.g. at or above 1000° C., is disclosed. The Zintl thermoelectric material may comprise Yb14MnSb11. A thin molybdenum metallization layer of approximately 5 microns or less may be employed. The thin molybdenum layer may be applied in a foil under high pressure, e.g. 1800 psi, at high temperature, e.g. 1000° C. The metallization layer may then be bonded or brazed to other components, such as heat collectors or current carrying electrodes, of the thermoelectric power generation device.
