Measurement of fluid properties

Note that the hydrometer is lower in the less dense liquid. Information, arguments, parameters, data, etc. The present invention is less costly and more efficient than existing methods.

Also notice the surface tension effects on the flow from tube C. Relative humidity is the ratio of the existing vapor pressure to saturated vapor pressure. In particular the present invention relates to analysing reservoir fluids at surface or subsea.

Notice that the upper limit for Poiseuille flow corresponds to a rather small tube and a small flow rate. They help to improve these processes, working to make them cost-effective and efficient, while considering the time constraints of their customers.

Poiseuille flow in a tube exists when 1. In one embodiment of the present invention a system of measuring physical properties of a non-Newtonian fluid is provided. Also, the method may comprise storing a sample for further analysis off-line in addition to the real time analysis.

Further, various components of the same type may be distinguished by following the reference label by a dash and a second label that distinguishes among the similar components. The pressure at the upstream end depends on the depth of liquid in the bucket above the tube inlet.

In the experiment, two hydrometers will be placed in graduated cylinders with water containing different concentrations of salt and therefore having different densities. A sample receptacle can be: Initially the reservoir fluid will be contaminated with drilling and cushion fluids, perforation and formation debris, and injected chemicals.

Particularly in these conditions, many existing methods for measuring the WLR which work on the flow rate are not successful due to the tiny volume of liquid to be split between the oil and water.

The method includes the following steps: Increased flow turbulence and advanced flow profile development are two factors which improve the accuracy of measurements. The system may comprise a container for holding the non-Newtonian fluid and a fluid resistance member.

Values of saturated vapor pressure for water are given in Table 1.

One of the properties of the fluid which may be readily measured in the flow stream is the water liquid ratio WLR in a multiphase flow line oil, water, gas for a large range of flowing conditions.

Furthermore, from the time a sample is collected until it is analysed, there is potential for the sample to be contaminated from air or other external fluids, for the sample to react with the sample receptacle, for components in the sample to react among themselves, for the sample to degrade with time, or for loss of the sample due to leaks.

This fluid is pumped downhole to fracture a rock formation, hence disposing of the cuttings. A trajectory in the absence of friction is can be described by 1.

An Introduction to Flow Measurement & Fluid Properties

According to existing methods, samples for analysis are typically taken remotely in a sample receptacle, transported to the location where the analysis instrument lies and then the samples are introduced into an analyzer for analysis.

For a more dense liquid, the hydrometer does not sink as far into the liquid. In a further form of the present invention the fluid analysis module may comprise a fluid sampling device in communication with the flow line; a gas-liquid separator for separating gas from liquids being in communication with the fluid sampling device; and a water to liquid ratio measurement device being in communication with the gas-liquid separator by means of a conduit having a diameter equal to or less than 3 millimeters.

Gases tend to need more vertical pipelines to establish an accurate measurement in comparison to liquids. Preferably the system is for the analysis of reservoir fluids from a well.The intensive fluid properties related to mass are The hydrometer floats in liquids with densities within the measurement range of the hydrometer.

For a floating object of any kind, equilibrium of forces requires that the buoyant force be equal to the weight of the object. The inline sensor assembly (25), as shown in FIG. 5, can be installed in fluid communication with the flow line (20) for direct measurement of the fluid properties of a fluid.

Fluid flows through the sensor module (22) via a pre-treatment module (26) where a property of the fluid is measured from the main flowline, before flowing back out.

The many applications of flow measurement include uses in water supply, medical research, oil exploration, food processing and distribution of gas. The uses of this technology are very diverse, with each different situation bringing unique challenges and requirements.

Proper measurement of physical properties requires the knowledge of specific terms, measuring units, and measuring devices.

This course covers the terminology needed to accurately monitor and measure equipment, as well as the measuring units and techniques that apply to temperature, force, and fluids.

This technology gives operators Berrim A: “Downhole pH as a Novel Measurement Tool. Experiment #2 Fluid Properties: Viscosity. Jordan Hines Performed on January 31, Report due February 7, The temperature of the fluid is the significant measurement because the density of the fluid is directly related to its temperature.

If the temperature were greater, the fluid would be less dense; conversely, if the temperature 5/5(4).
