1.1 About this manual

1.3 Introduction to the ALTUS™ NOC

Replacing an older NOC and transmitter

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

ALTUS Installation Manual

the

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.

The ALTUS NOC works with a Micro Motion® sensor to produce realtime 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.

If an AL TUS 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

ALTUS™ Net Oil Computer Manu al

The NOC calculates water cut from the following equation:

Where

= Emulsion density

= Oil density

= 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 temperature (100°F in

Figure 1-1

). The Micro Motion sensor measures the fluid

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.

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.

• 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

Sensor orientation

Install the sensor according to the appropriate sensor instruction manual.

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.

Avoiding inaccurate flow counts

continued

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.

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 criterio n shou ld be followed:

Where:

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

separator to sensor inlet

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

sensor inlet

= Pressure drop across sensor

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

ALTUS™ Net Oil Computer Manu al

Installation Considerations

continued

The following general guidelines are suggested:

• To maximize the static head gain (P

), 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 (P

), 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 (P

), 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.

Using the Person-Process

Interface

2.3 Flow direction

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.

The sensor measures accurately regardless of flow direction. The arrow on the sensor housing indicates normal forward flow direction. Refe r to

to indicate forward flow, reverse flow, or forward and reverse flow.

Transmitter alarm messages

The ALTUS transmitter produces several types of alarm messages. The following types of alarms do not drive outputs to fault levels:

• Slug flow and output saturation alarms

• Totalizer alarms

• Calibration and trim alarms

• Conditional status alarms The following types of alarms drive outputs to fault levels:

• Critical status fault alarms

• Transmitter failure fault alarms

• Sensor error fault alarms

ALTUS™ Net Oil Computer Manu al

Maintenance

continued

Well Test Mode Maintenance

Alarms that do not generate fault outputs

Slug flow alarms

Conditions 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.

Fault outputs

Outputs go to fault levels if a fault is detected. The transmitter also produces fault outputs when you perform configuration, calibration, or diagnostic tasks. See

Table 8-7

The transmitter can be configured to produce downscale, upscale, last measured value, or internal zero fault outputs. See

Table 8-8

• To configure fault outputs, see page 37 and page 40.

• The default configuration for fault outputs is downscale.

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.

Density unit for calibration

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.

Density calibration requires reading and entering density values in grams per cubic centimeter.

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.

9 Laboratory Determination of

Dry Oil and Produced Water 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.

Use one of the following sampling procedures:

Method 1

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

Method 2

• pressure is less than 80 psig, or where flexible stainless steel tubing is available.

Laboratory Determination of Dry Oil and Produced Water Densities

Method 1

Use 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

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.
