Abstract: Methods for determining phase fractions of a downhole fluid via thermal properties of the fluids are provided. In one embodiment, a method includes measuring a temperature of a fluid flowing through a completion string downhole in a well and heating a resistive element of a thermal detector at a position along the completion string downhole in the well by applying power to the resistive element such that heat from the resistive element is transmitted to the fluid flowing by the position. The method also includes determining, via the thermal detector, a flow velocity of the fluid through the completion string and multiple thermal properties of the fluid, and using the determined flow velocity and the multiple thermal properties to determine phase fractions of the fluid. Additional systems, devices, and methods are also disclosed.

Abstract: Multiphase flow metering is provided. In one possible implementation, a multiphase flow measurement system includes at least one reference temperature sensor at a first position configured to measure a first temperature of a multiphase flow. The multiphase flow measurement system also includes at least one heated temperature sensor at a second position downstream of the reference temperature sensor configured to excite the multiphase flow and measure a second temperature of the multiphase flow.

Abstract: In an embodiment a method is described which includes emplacing a sample within a measurement cell, wherein two or more electrodes are configured in the measurement cell; introducing a reactive fluid into the measurement cell; reacting the sample with the reactive fluid, wherein reacting the sample with the reactive fluid results in a change in an ion concentration in the reactive fluid; and measuring the resistivity of the reactive fluid using the two or more electrodes, wherein the resistivity is proportional to the ion concentration in the reactive fluid.

Abstract: An emulsion is mixed with fibers while the emulsion is moving through a surface tubing using a venturi. The fiber/emulsion mixture is injected into a pressurized tank and the pressurized fiber/emulsion mixture is injected from the pressurized tank into a desired location in a wellbore. Pumps and pressure boosters may be used to move the fluid.

Abstract: An emulsion is mixed with fibers while the emulsion is moving through a surface tubing using a venturi. The fiber/emulsion mixture is injected into a pressurized tank and the pressurized fiber/emulsion mixture is injected from the pressurized tank into a desired location in a wellbore. Pumps and pressure boosters may be used to move the fluid. Alternatively, an emulsion and a fiber suspension is provided and a first downhole tubing disposed in a wellbore conveys the emulsion downhole while a second downhole tubing disposed in the wellbore and circumferentially enclosing all or part of the first downhole tubing conveys the fiber suspension downhole. The first downhole tubing has nozzles through which the emulsion passes into the second downhole tubing and the emulsion and the fiber suspension mix. The mixture exits the second downhole tubing through ports at a desired location in the wellbore.
