Measurement of fluid properties

Such decisions are of particular importance in making decisions during well test, clean-up operations or well production. These chemical agents may then be separated from the sampled stream before discharging the sampled stream back into the flow line or a container as the case may be for later treatment or disposal.

Even though the primary purposes of this part of Measurement of fluid properties lab are related to viscosity, notice that the diameter of the jet for A decreases as it falls into the downstream bucket and that some of the jet breaks into droplets before the jet reaches the bottom of the downstream bucket.

The fluid sampling device may be used to return a fluid sample to the flow line. 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.

Careful design and sag measurement of CRI fluids is required to avoid unwanted sedimentation of the cuttings. Observe the pulsating flow for A when the upstream bucket is full.

Provisional Patent Application Ser. The method can further comprise removing contaminants from the fluid sample. The present invention system and method overcomes some of the drawbacks of existing systems and methods, allowing for continuous fluid property analysis of reservoir fluids on site.

It also eliminates the long delays in the shipping of samples to laboratories required by existing techniques.

The rheological properties of liquids containing a dispersed solids particulate phase are well-studied. A processor s may perform the necessary tasks. Increased flow turbulence and advanced flow profile development are two factors which improve the accuracy of measurements.

This application further overcomes the difficulty in making the WLR measurement itself because of the differences in physical properties of the oil and water in standard flow lines by the measurement made in a very small or mini-channel where the superficial tension maintains both phases at the same speed.

It is common practice today during a well test, to take spot samples for analysis at the wellsite. The fluid sample can be discharged back into the flow line after measuring a property of the fluid. Traditionally in most oilfield applications the hydrocarbon composition, trace elements and physical properties of reservoir fluids are measured at the surface adjacent the well using laboratory style instruments, analysers and equipment which may not necessarily be adapted to field measurements.

This process is labor intensive and time consuming. Torque required to maintain the movement of the member through the non-Newtonian fluid may be measured and at least one physical property of the fluid, other than apparent viscosity, may be determined from a known relationship between the measured torque and the physical property of interest.

This is, to a varying extent, the situation with measurements of the pH of water, the H2S concentration in gas, Hg in gas, and radon in gas. When a process corresponds to a function, its termination corresponds to a return of the function to the calling function or the main function.

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.

In one embodiment of the present invention a system of measuring physical properties of a non-Newtonian fluid is provided.

An Introduction to Flow Measurement & Fluid Properties

Initially the reservoir fluid will be contaminated with drilling and cushion fluids, perforation and formation debris, and injected chemicals.

When the two pressures become equal due to an increase in temperature, the process is normally called boiling.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. Advancing Fluid-Property Measurements Soraya Betancourt Cambridge, Massachusetts, USA Tara Davies reservoir-fluid properties and quantification of their variation. This technology gives operators Berrim A: “Downhole pH as a Novel Measurement Tool.

In this course, you will conduct the experiments at the Fluid Mechanics Laboratory, by yourselves, without any help or instruction from the teaching assistants.

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.

A system and method for measuring physical properties of non-Newtonian fluids, such as fluids containing dispersed solid particulate material and having a yield stress. A fluid resistance member is moved through the non-Newtonian fluid sufficiently slowly that viscous drag on the member is negligible and fluid resistance is essentially due to the yield stress of the fluid.

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.
