1.1 About this manual This manual explains how to configure, operate, and maintain the ALTUS™ Net Oil Computer (NOC). This manual does not explain installation or wiring. For information about installation and wiring, see the ALTUS Installation Manual.

1.2 Application software described in this manual

This manual pertains to software menus that enable operation, configuration, and maintenance of the NOC.• The ALTUS applications platform has software functions that do not

pertain to the NOC.• For information about software functions that are not described in

this manual, refer to the installation and detailed setup manuals for the applications platform.

1.3 Introduction to the ALTUS™ NOC

The ALTUS NOC works with a Micro Motion® sensor to produce real-time measurements of water cut, net oil volume flow, and net water volume flow. The NOC measures full-stream mass flow and volumetric flow at rates from a few barrels to more than 100,000 barrels per day.

Replacing an older NOC and transmitter

If an ALTUS NOC is installed as a replacement for an older Micro Motion Net Oil Computer and RFT9739 or RFT9712 transmitter, power-supply and output wiring does not need to be replaced. Because transmitter software is included with the ALTUS NOC, a transmitter is not required.

Water cut determination The NOC calculates water cut from the following equation:

Where:De = Emulsion densityDo = Oil densityDw = Water density

Figure 1-1 , page 2, shows how water cut is calculated by the NOC. The operator enters the oil and water densities at the reference temperature (60°F in Figure 1-1 ). The Micro Motion sensor measures the fluid temperature (100°F in Figure 1-1 ). The NOC extrapolates the densities to the operating temperature, using an API equation for oil and a Chevron Research equation for produced water. The water cut equation is solved at operating temperature, then referenced back to 60°F. Using water cut, mass flow rate, and net oil and water densities, the NOC calculates net oil, net water, and gross flow at reference temperature.

Figure 1-1. Water cut calculation

NOC capabilities The NOC can operate in continuous mode or well test mode:• In continuous mode, the NOC can continuously monitor a well,

separator, or pipeline.• In well test mode, the NOC can perform a well test on any of up to 48

different wells. Well performance data for the test that is in progress or for previous tests can be viewed during the test.

The NOC nonvolatile memory archives data acquired during the last three well tests. The NOC resumes testing if a power failure or shutoff interrupts the test that is in progress. The last three power outages are recorded with power-on and power-off time/date stamps.

The NOC has three discrete outputs, two milliamp outputs, and a pulse output:• Discrete output 1 can be an alarm for transient bubble remediation.• Discrete output 2 indicates net oil. It produces 10 output pulses per

barrel or 10 output pulses per cubic meter of net oil.• Discrete output 3 indicates net water. It produces 10 output pulses

per barrel or 10 output pulses per cubic meter of net water.• Milliamp output 1 can indicate any measured variable.• Milliamp output 2 can indicate any measured variable.• The pulse output can represent a flow variable.

The NOC can remediate density readings to compensate for the presence of transient bubbles in the sensor. If erratic density resulting from transient bubbles causes sensor drive gain to exceed the programmed value, the NOC can be programmed to respond in one of three ways:• The NOC can hold the density value that was measured at a

specified time before transient bubbles were detected.• The NOC can produce an alarm indicating the presence of transient

bubbles. The alarm can be assigned to discrete output 1.• The NOC can stop the well test that is in progress.

2 Installation Considerations

2.1 Piping arrangement and ancillary equipment

Figure 2-1 , page 4, shows a typical installation of a sensor and an NOC when a 3-phase test separator is used.

Figure 2-2 , page 4, shows a typical installation of a sensor and an NOC when a 2-phase test separator is used.

Adhere to the following general guidelines:• Design and size the test separator to ensure complete separation of

the entrained gas from the liquid phase.• Size the Coriolis sensor so that at maximum liquid flow, pressure

drop is less than 3 psi.• Install the sensor as far below the test separator as possible.• Install the sensor upstream from the dump valve .• Balance any sensor pressure drop with hydrostatic head, measured

from the lowest level in the separator down to the sensor inlet. Rule of thumb: pressure drop should be about 0.4 psi per foot.

• If the liquid temperature is significantly different from the ambient temperature, thermally insulate or heat trace the sensor and upstream pipe to minimize paraffin coating and transient temperature at the start of dumping periods.

• Install a meter proving loop, if required.• Install a static mixer and sampling port for calibration and verification

purposes. Locate the static mixer and sampling port downstream from the sensor and the proving loop connections.

• Make sure the dump valve is capable of regulating back pressure and controlling the liquid flow rate.

2.2 Sensor installation Install the sensor according to the appropriate sensor instruction manual.

Sensor orientation If possible, mount the sensor with its flow tubes downward in a horizontal pipe run, as shown in Figure 2-3 .

If necessary to prevent sand or other solid particles from accumulating in the flow tubes, or to accommodate existing vertical piping, mount the sensor in a vertical pipe run, as shown in Figure 2-4 . The oil/water interface should flow upward through the pipeline.

Installation Considerations continued

Avoiding inaccurate flow counts

Because the crude oil in the separator is at an equilibrium condition, any pressure reduction can cause the solution gas (i.e., the light end components) to break out from the saturated crude oil.

Even a seemingly small amount of free gas in the liquid phase can result in substantial measurement errors in water cut and net oil. (See pages 107-109 to estimate the effect of free gas).

The amount of gas that is produced varies, and depends on the properties of the crude oil and the operating conditions.

To prevent formation of solution gas in the flowmeter, the following criterion should be followed:

Where:Pg = Static head pressure of liquid, measured from liquid level at

separator to sensor inletPp = Frictional pressure loss of flow line, from test separator to

sensor inletPm = Pressure drop across sensor

Detailed pressure drop calculations are strongly recommended during design and installation of the piping system.

CAUTION

Settling of the oil/water interface in a sensor can cause the flowmeter to indicate flow when there is no flow.

• To avoid inaccurate flow counts, program a low flow cutoff. To program a low flow cutoff, see page 25.

• Settling of the oil/water interface is more likely to occur if the sensor is mounted in a vertical pipe run than if the sensor is mounted in a horizontal pipe run.

The following general guidelines are suggested:• To maximize the static head gain (Pg), install the sensor as far below

the test separator as possible.• Note that 1 psi (6.9 kPa) of static head gain results from 28 inches of

water column.• To minimize the frictional head loss (Pp), install the sensor as near as

possible to the test separator, and use larger-diameter connecting pipes. Minimize use of piping elements such as tees, elbows, and reducing unions.

• Install sampling ports, static mixer, proving connections, dump valve, back pressure regulator, or other flow-restricting devices downstream from the sensor. A full-port valve should be considered if a cutoff valve must be installed between the separator and the sensor.

• Whenever possible, frictional pressure loss should be less than 3 psi (20.7 kPa) at the maximum anticipated flow rate.

• To minimize pressure drop across the sensor (Pm), install a larger sensor. Pressure drop across the sensor should be less than 3 psi (20.7 kPa) at the maximum anticipated flow rate.

• In some environments, extremely tight emulsion occurs. Extremely tight emulsion can make removal of entrained gas difficult, even with a large separator. Using a suitable demulsifier chemical to break down the emulsion is a possible method of alleviating this problem.

If the sensor is installed directly at the wellhead, (i.e., if a test separator is not used), the line pressure at the sensor should be maintained above the crude oil bubble point pressure.

2.3 Flow direction The sensor measures accurately regardless of flow direction. The arrow on the sensor housing indicates normal forward flow direction. Refer to the ALTUS Detailed Setup Manual for directions about setting the NOC to indicate forward flow, reverse flow, or forward and reverse flow.

Alarms that do not generate fault outputs

Slug flow alarmsConditions such as slug flow (large gas bubbles in a liquid flow stream) adversely affect sensor performance by causing erratic vibration of the flow tubes, which in turn causes the transmitter to produce inaccurate flow signals. If you program slug limits, a slug flow condition causes the transmitter to produce slug flow alarms.

The "Slug Flow" alarm indicates slug flow has occurred for less than the amount of time that is configured for the slug time. Outputs indicating the flow rate remain at the last measured flow rate before the slug flow condition occurred.

The "Slug Timeout" alarm indicates slug flow has occurred for more than the amount of time that is configured for the slug time. If the "Slug Timeout" alarm occurs, outputs indicating the flow rate go to the level that represents zero flow.• All outputs other than flow rate outputs continue to indicate the

measured value for the process variable.• The flowmeter resumes normal operation when density stabilizes

within the programmed slug flow limits.• Slug time can be up to 300 seconds.• If slug time is configured for 0.0 seconds, outputs indicating the flow

rate will go to the level that represents zero flow as soon as slug flow is detected.

Table 8-2 summarizes slug flow alarms and lists corrective actions.

Output saturation alarmsIf an output variable exceeds the upper range limit or goes below the lower range limit, the transmitter produces an output saturation alarm. The alarm can mean the output variable is outside appropriate limits for the process, or can mean measurement units need to be changed.

Totalizer alarmsIf the totalizers are operating, the transmitter produces totalizer alarms. Table 8-4 summarizes totalizer alarms and lists corrective actions.

8.4 Density calibration At the factory, Micro Motion calibrates each NOC to work with a specific sensor. The NOC requires a field density calibration in the following situations:• The sensor flow tubes have become permanently

coated.• The sensor flow tubes have eroded.

If density calibration is necessary, use any of the following methods to calibrate the NOC:• Duplicate the factory calibration, as instructed on

page 81.• Duplicate a previous field calibration, as

instructed on page 82.• Use two fluids with known densities to perform a

density calibration, as instructed on pages 83-86.

Two-point density calibration

During 2-point density calibration, you command the transmitter to measure the sensor tube period when the flow tubes contain a fluid with a reference low density (usually air) and when the flow tubes contain a fluid with a reference high density (usually water).

Two-point density calibration is preferably performed under zero flow conditions. The calibration procedure includes a low-density calibration and a high-density calibration. If necessary, you can perform only the high-density calibration.

To prepare for the density calibration:1. Use produced water to flush the flow line.2. Remove the sensor from the flow line.3. Drain the fluid from the sensor.4. Rinse the sensor tubes with toluene at least twice, then rinse the

tubes with acetone at least twice. Use another oil solvent if toluene or acetone is not available.

5. Use compressed air to blow the sensor dry until residual acetone or other solvent has been completely evaporated.

6. If sensor wiring was disconnected at step 2, reconnect the wiring and cycle power off, then on.

7. Wait approximately 5 minutes for the sensor flow tubes to achieve the ambient air temperature.

CAUTION

Selecting calibration will interrupt control functions. All control outputs will go to their configured idle settings.

Set control devices for manual operation before accessing calibration menus.

9 Laboratory Determination ofDry Oil and ProducedWater Densities

9.1 Reasons for using live oil density

To enable the most accurate possible water cut and net oil measurements, "live oil" density rather than "dead oil" density should be programmed into the NOC. "Live oil" refers to the crude oil at line conditions. Reducing the operating pressure to atmospheric pressure causes the live oil to lose its solution gas or light-end components and become a dead oil at a greater density than when it was under pressure.

The difference between the density of live oil and the density of dead oil can be quite significant, depending on the gas-to-oil (GOR) ratio and the separator pressure and temperature. If dead oil density is used, water cut measurements will be too low, and net oil will be too high.

This chapter describes the laboratory method for measuring dry oil and produced water densities.• The method involves using a precision density meter to determine

the density of a liquid sample taken from the flow line.• The method requires correcting measured densities of dry oil and

produced water to 60°F.

To obtain an IBM-compatible software program for computing corrected crude oil and produced water densities, phone the Micro Motion Customer Service Department:• In the U.S.A., phone 1-800-522-6277, 24 hours.• Outside the U.S.A., phone 303-530-8400, 24 hours.• In Europe, phone +31 (0) 318 549 443.• In Asia, phone (65) 770-8155.

9.2 Laboratory density measurement

The laboratory method requires the equipment listed in Table 9-1 .

Taking a sample from the flow line

Locate the sample port downstream from the sensor, as shown in Figure 9-1 . The sampling port should protrude into the flow line, with the probe opening situated near the center of the flow pipe. To ensure a representative sampling, install a static mixer immediately upstream from the sample port.

Use one of the following sampling procedures:• Method 1 involves using a water-filled sample cylinder if separator

pressure is higher than 80 psig, or where flexible stainless steel tubing is not available.

Method 1Use a water-filled sample cylinder if separator pressure is higher than 80 psig, or when flexible stainless steel tubing is not available.1. Fill the clean sample cylinder with produced water, preferably the

water from the well being tested or water with similar salinity. Pressurizing the sample cylinder is not necessary.

2. Connect the sample cylinder to the sampling port as shown in Figure 9-2 . Close V-1, V-2, V-3, and V-4.

3. Open V-1, then open V-4 to purge the connecting lines briefly. Close V-4 and open V-2 to equalize the pressure in the sample cylinder.

4. Slowly open V-3 to draw liquid into the sample cylinder and to displace the water in the sample cylinder.

5. Close V-3 when a trace of oil appears at the drain port.6. Wait for a few minutes to allow the free water to settle in the sample

cylinder. The wait time varies, depending on whether the oil and water are readily separable.

7. Slowly open V-3 to drain the free water from the bottom drain port and to allow additional liquid sample to flow into the sample cylinder. Close V-3 when a trace of oil appears at the drain port.

8. Repeat steps 6 and 7 several times until the amount of free water drained is less than 50 ml. This indicates that a sufficient amount of oil/water emulsion has been collected in the sample cylinder.

9. Close V-1, V-2, and V-3. Open V-4 to depressurize the sample line.10. Remove the sample cylinder. Record well I.D., sample pressure, and

sample temperature.

Method 2Use an empty sample cylinder if separator pressure is less than 80 psig, or where flexible stainless steel tubing is available.1. Connect an empty sample cylinder to the sampling port as shown in

Figure 9-3(A) , with V-1, V-2, V-3 and V-4 closed. The outlet port should point upward at about 75 degrees from horizontal.

2. Open V-1, then open V-2.3. Slowly open V-3 to withdraw liquid sample into the sample cylinder

and purge the air out of the sample cylinder. Close V-3 when a trace of liquid appears at the outlet port.

4. Secure the sample cylinder to a support base as shown inFigure 9-3(B) . Outlet V-3 should point downward.

5. Wait for a few minutes to allow the free water to separate in the sample cylinder. The wait time varies, depending on whether oil and water are readily separable.

6. Slowly open V-3 slowly to drain the free water from V-3 and withdraw oil/water mixture into the sample cylinder. Close V-3 when a trace of oil appears at the outlet port.

7. Repeat steps 5 and 6 several times until the amount of free water drained is less than about 50 ml. This indicates that a sufficient amount of oil/water emulsion has been collected in the sample cylinder.

8. Close V-1, V-2, and V-3. Open V-4 to depressurize the sample lines.9. Remove the sample cylinder. Record well I.D., sample pressure, and

temperature.

Processing sample and measuring densities

1. Secure the sample cylinder in an upright position for a sufficient period of time (overnight, for example) to allow additional free water to settle. If the emulsion is very tight, place the entire sample cylinder in a heated oven or hot bath, or use a temperature-regulated heating tape to enhance oil-water separation.

2. If the sample cylinder is heated, allow it to cool to ambient temperature before proceeding.

3. Connect the sample cylinder between the nitrogen cylinder and a high precision laboratory density meter.• If operating pressure is lower than 80 psig, use the setup shown

in Figure 9-4 , page 92.• If operating pressure is higher than 80 psig, use the setup

shown in Figure 9-5 , page 92.4. Close all valves (V-1 through V-6).5. Set nitrogen pressure at 10 psi higher than the separator pressure.6. Calibrate the laboratory density meter in accordance with

manufacturer's instruction. To prevent flashing of solution gas in the crude oil, set the temperature of the density meter at least 10°F below the separator temperature.

7. Slowly open V-1 and V-2 to equalize the pressure in the sample cylinder. Leave V-1 and V-2 open throughout the entire density determination process.

8. Open V-3, then slowly open V-4 to drain the free water into a beaker. Save about 20 ml of clean water for later use.

9. Continue to drain the remaining free water from the sample cylinder until a trace of crude oil appears in the outlet port. Continue to drain and discard about 10 ml of oil water mixture. Close V-4.

10. Slowly open V-5 to equalize the pressure in the density meter.11. Slowly open V-6 downstream from the density meter to allow a few

milliliters of crude oil to flow through the density meter. Turn on the compartment light of the density meter to make sure no gas bubbles are present in the density meter tube.

12. Turn off the compartment light of the density meter. Wait a few minutes for the displayed density reading to stabilize.

13. Repeat steps 11 and 12 several times until the difference between the two consecutive density readings is less than or equal to 0.0002 g/cc.

14. Slowly open V-6 and drain about 60 to 70 ml of the sample into a separate container.

15. Record the density of the sample remaining in the density meter. Record the density reading as "emulsion" density (Det).

16. Use a centrifuge method or another acceptable method (distillation, Karl-Fischer, etc.) to determine the water cut of the oil/water mixture sample collected in step 14. Report the water cut value as Xw, in volume fraction.

17. If the low-pressure setup in Figure 9-4 is used, disassemble the pressure adaptor from the density meter and use a proper solvent to clean the density meter.

18. Using a plastic-tip hypodermic syringe, inject the produced water obtained at step 8 into the density meter. Report the reading as Dwta ("a" stands for atmospheric pressure).

10 In-Line Determination ofLive Oil and ProducedWater Densities

10.1 Reasons for using live oil density

To enable the most accurate possible water cut and net oil measurements, "live oil" density rather than "dead oil" density should be programmed into the NOC. "Live oil" refers to the crude oil at line conditions. Reducing the operating pressure to atmospheric pressure causes the live oil to lose its solution gas or light-end components and become a dead oil at a greater density than when it was under pressure.

The difference between the density of live oil and the density of dead oil can be quite significant, depending on the gas-to-oil (GOR) ratio and the separator pressure and temperature. If dead oil density is used, water cut measurements will be too low, and net oil will be too high.

This chapter describes the in-line method for measuring dry oil and produced water densities, using the density determination software in the ALTUS™ NOC.

10.2 In-line density determination

Use the in-line method for determining dry oil and produced water densities in situations where dry oil or a stable emulsion can be obtained under separator conditions.

Density determination procedures

Density determination involves the following procedures:• Measuring and saving or manually entering the water density.

(Manual entry is usually done when water cut is low. Obtain a water sample from the water trap or drain cock on the separator.)

• Measuring and saving the oil density.• Entering the water cut.

CAUTION

Selecting calibration will interrupt control functions. All control outputs will go to their configured idle settings.

Set control devices for manual operation before accessing calibration menus.

Example: Find the approximate number of gallons of liquid in a horizontal vessel with spherical ends if the vessel has a diameter of 4 feet, a length of 10 feet, and a liquid level at 2 feet, 9 inches.

A liquid level of 2 feet, 9 inches is approximately 70% of the capacity of a tank with a 4-foot diameter:

0.7477 x D x D x 10 x 5.875 = 702.8 gallons, or approximately 703 gallons.

Add 201 gallons to 703 gallons for the spherical ends.

The approximate amount of liquid in the tank is 904 gallons, or 21 barrels.

11 Sensitivity Analysis

11.1 Error factors The accuracy of water cut and net oil measurements obtained by the NOC is sensitive to the accuracy of the following parameters:• Density of dry crude oil (input to NOC)• Density of produced water (input to NOC)• Density of oil/water mixture (measured by mass flowmeter)• Mass flow rate (measured by mass flowmeter)• Presence of free gas (system upset)

11.2 Individual sensitivity Table 11-1 lists formulas for calculating the uncertainty of water cut and net oil volume caused by the uncertainty of each of the independent parameters listed above.

Table 11-1. Uncertainty factors for percent water cut and percent net oil

Variable % water cut uncertainty 1 % net oil uncertainty 2

Dry crude oil density (Do)3

Water density (Dw)3

Mixture density (De)3

Mass flow rate (Me)4 No effect

Free gas content5

1 The water cut uncertainty is defined as: (Indicated water cut – True water cut) X 100%2 The net oil volume uncertainty is defined as: (Indicated oil volume – True oil volume) ÷ (True oil volume) X 100%3 Do, Dw, and De refer to, respectively, density (in g/cc) of crude oil, produced water, and oil/water mixture.

δDo, δDw, and δDe refer to, respectively, uncertainty of density (in g/cc) of crude oil, produced water and oil/water mixture4 Me denotes mass flow rate of the mixture, δMe denotes uncertainty of mass flow rate5 Xw denotes water cut, and δXg denotes free gas content, both in volume fraction

Sensitivity Analysis continued

11.3 Overall uncertainty Use the following formula to estimate the overall uncertainty:

Where:δDo = Dry oil density uncertainty δDw = Produced water density uncertaintyδDe = Mixture density uncertaintyδMe = Mass flow rate uncertaintyδXg = Free gas content

Overall uncertainty = δDo2 δDw2 δDe2 δMe2 δXg2+ + + +( )

Effect of dry oil density variation:

Over-estimating dry oil density would cause water cut to read low, net oil volume to read high.

Effect of produced water density variation:

Over-estimating produced water density would cause water cut to read low, net oil volume to read high.
