Abstract: A technique facilitates evaluation of a fluid, such as a fluid produced from a well. The technique utilizes a modular and mobile system for testing flows of fluid which may comprise mixtures of constituents, and for sampling fluids thereof. The multiphase sampling method includes flowing a multiphase fluid comprising an oil phase and a water phase through a first conduit, the oil phase and water phase at least partially separating in the first conduit, mixing together the oil phase and water phase to form a mixed bulk liquid phase by flowing the multiphase fluid through a flow mixer toward a second conduit downstream the flow mixer, sampling a portion of the mixed bulk liquid phase at location at or within the second conduit, wherein the sampled portion of the mixed bulk liquid phase has a water-to-liquid ratio (WLR) representative of the pre-mixed oil phase and water phase.

Abstract: A tomography system for determining properties of flowing multiphase fluid, comprising a duct having a duct wall and interior space within the duct wall for carrying a flow of the multiphase fluid and a plurality of sensors, which are electrodes or coils, at positions distributed around the duct wall on a planar cross section through the duct, wherein the sensors (electrodes or coils) are used for making a plurality of measurements of electrical or magnetic properties through the duct wall and the multiphase fluid; and a processor is used to receive measurement data from the sensors and to compute from the measured properties to derive quantitative values of at least one property selected from permittivity, conductivity, magnetic permeability and complex-conductivity of the multiphase fluid independent of effects external to the fluid flow, such as effects of the duct walls and the geometry of the positioning of the sensors (electrodes or coils).

Abstract: Disclosed herein is an apparatus including a structure containing a multiphase fluid and having a transparent window. A collimated light source emits light through the transparent window structure at a wavelength at which a component of a desired phase of the multiphase fluid is absorptive. A photodetector is positioned such that the emitted light passes through the multiphase fluid in the structure and out through the transparent window structure to impinge upon the photodetector. The photodetector has an actual dynamic range for light detection. Processing circuitry adjusts a power of the collimated light source in a series of steps dependent upon a relationship between an output level of the photodetector and a threshold to cause measurement of the emitted light over an effective dynamic range greater than the actual dynamic range. Properties of the multiphase fluid are determined as a function of the measured emitted light.

Abstract: Properties of a multiphase mixture flow are measured in a blind-tee. The measured properties include the permittivity and/or the conductivity of the multiphase mixture flowing through a conduit. The permittivity and/or conductivity are measured at liquid-rich region(s) in a blind-tee section of the conduit and are used to determine properties of a liquid phase of the multiphase fluid flow, including one of the water conductivity, water in liquid ratio and water volume fraction. One or more electromagnetic sensors may be used in the blind-tee to measure the permittivity and/or conductivity. The sensors may be in contact with the multiphase flow or be disposed behind a dielectric window.

Abstract: A system and method for determining characteristics of a multiphase flow in a well/pipe are disclosed. The disclosed system and method use an optical immersion probe including a flow gap across which two or more types of radiation are transmitted in order to measure absorptions of two or more substances within the multiphase flow. Primarily, broadband ultraviolet (UV) and/or near infrared radiations (NIR) are utilized with the probe to gather absorption data at and/or around at least one of the water peaks and at and/or around one or more oil or oil-condensate peaks. This data may be utilized to calculate the water-cut of the multiphase flow over a wider range of gas volume fractions. Additionally, pressure ports having pressure sensors being located on the optical immersion probe for determining the impact pressures and flow rates of different phases of the multiphase flow may also be used.

Abstract: An immersion probe is described that includes sensing elements that allow for hydrate inhibitor dosage to be more efficiently provided into gas and/or oil wells. The immersion probe allows for detection of first appearance of water in a multiphase flow in a well, measuring the amount of inhibitor in water within the well, determining an accurate water-cut, and measuring other property such as water salinity. Accordingly, with the known water-cut, salinity and the water flow rate inferred from the inhibitor injection flow rate and inhibitor-in-water fraction, a correct dosage of the inhibitor can be injected to the well in order to prevent hydrate formation, while reducing overdosing. Water flow rate may also be inferred from an independently measured liquid flow rate and the immersion-probe measured water cut.
