2.3 Internal structure of the Net Oil Computer Software

The Net Oil Computer Software is a ROC809 user program. It was loaded onto the ROC809 platform during installation (see the manual entitled Micro Motion Net Oil Computer Software and NOC System: Installation Manual). The Net Oil Computer Software has the following structure:

• NOC Station display – Station configuration and data, and gas measurement configuration and data (optional). The NOC system performs NOC measurement for one station.

• Well Data display – Well configuration and history for each well.

• MMI Interface display – Sensor configuration and process data for Micro Motion sensors.

NOC System Overview NOC DisplaysROC809 SetupBefore You Begin

• NOC Meter display – NOC measurement configuration and real-time calculated data. Each NOC measurement sensor is configured and monitored separately.

• NOC Recalc display – Recalculation functions for the ten most recent contract periods (Continuous mode) or for the ten most recent well tests performed within the ten most recent contract periods (Well Test mode)

2.4 Sensor input to the Net Oil Computer Software

Figures 2-1 and 2-2 illustrate two possible implementations of the Net Oil Computer Software, supporting two different sensor input options:

• In Figure 2-1, two MMI sensors are installed on the oil leg, one MMI sensor is installed on the water leg, and one MMI sensor is installed on the gas leg.

• In Figure 2-2, one MMI sensor is installed on the oil leg, one MMI sensor is installed on the water leg, and a conventional meter is installed on the gas leg.

Note: These figures illustrate all sensor types, but do not illustrate all possible combinations.

2.4.1 Mapping NOC Meters to MMI sensors

Figure 2-3 illustrates the standard method for mapping NOC Meters to MMI sensors. You may be using one, two, or three NOC Meters.

As shown in Figure 2-3:

• A Modbus device address is assigned to each MMI sensor. This address resides in the sensor’s core processor. Typically, this configuration step is performed at the factory, and device addresses 1, 2, and 3 are assigned. If the device addresses are not preconfigured:

- The default Modbus address for a core processor is 1.

- If you need to change the default address, use ProLink II to connect directly to the core

• All MMI sensors communicate with the ROC809 and the Net Oil Computer Software through

processor.

the RS-485 sensor communications module, which is typically installed in ROC809 COM 4 (also called COMM3 or DNOC).

• An MMI Interface must be configured for each MMI sensor. The MMI Interface must identify:

- The comm port where the RS-485 sensor communications module is installed

- The Modbus device address of the Micro Motion sensor to use

• The NOC Meters are automatically mapped to the corresponding MMI Interfaces:

- NOC Meter #1 → MM #1

- NOC Meter #2 → MM #2

- NOC Meter #3 → MM #3

2.4.2 Water leg measurement versus liquid leg measurement

The default NOC Meter configuration assumes that the NOC Meter is associated with an MMI sensor installed on the liquid or oil leg. In this configuration:

To use a NOC Meter on the water leg, set the Free Water Setpoint to 0. As a result:

• The process fluid is assumed to be a mixture of oil and water.

• The “applied” water cut value is determined according to water cut configuration (see Section 2.7), and this value is applied to process fluid measurements.

• The applied water cut value is compared to the configured Free Water Setpoint (see Section 4.2.1) to determine how instant values, totals, and averages are updated:

- When the applied water cut is equal to or below the Free Water Setpoint, the process fluid

is treated as a combination of oil and water. Values for free water are not updated from this stream. Values for mixture water and total water will be updated.

- When the applied water cut is above the Free Water Setpoint, the process fluid is treated as

water. Only values for free water and total water are updated from this stream. Values for mixture water are not updated.

• The process fluid is assumed to be water.

• No water cut options and calculations are applied.

• Only free water and total water values will be updated from this stream.

2.5 Operation modes

The NOC system operates in either Well Test mode or Continuous mode:

• In Well Test mode, well tests can be performed on up to 50 wells. A manifold system is used to ensure that output from a single well is routed through the test separator and the NOC system. See Figure 2-4.

• In Continuous mode, one well is measured continuously. See Figure 2-5.

After initial configuration, you can change the operation mode. However, changing modes affects current measurement, data collection, and tags. Before changing modes, see Sections 8.2.1 and 8.2.2.

Figure 2-4 Well Test mode

NOC System Overview NOC DisplaysROC809 SetupBefore You Begin

Figure 2-5 Continuous mode

2.6 Required well data

If you will use the density-based water cut, the following information is required for each well that will be tested or measured by the NOC system:

• Density of dry oil from this well, at reference temperature and 1 ATM pressure

• Density of the water from this well, at reference temperature and 1 ATM pressure

• Purge time (Well Test mode only)

Configuration and Use Manual 11

NOC System Overview

If the density values are not known, you can perform an in-line density determination for oil, water, or both (see Chapter 7), or you can enter default values at initial configuration and recalculate measurement data at a later time when well-specific density values are known (see Section 8.7).

If you will use only water cut probes for water cut data, these density values are not required.

2.7 Water cut determination

You must configure water cut options for each NOC Meter that is measuring oil (i.e., each MMI sensor installed on the liquid leg). Do not configure water cut options for a NOC Meter that is measuring free water (i.e., the MMI sensor installed on the water leg).

There are two methods available for water cut determination:

• Density-based – The NOC equations are applied to derive water cut from measured density values.

• Water cut probe (WCP) – One or two water cut probes are used to measure the process stream directly. For example, you might use a capacitance probe at the low end and a microwave probe at the high end. Typically, the NOC system software receives data from these probes via an analog input.

If no water cut probe is installed, you must use the density-based water cut value. If one or two water cut probes are installed, you may:

• Ignore the WCP values for all NOC measurements

• Use the WCP values for all NOC measurements

• Define specific water cut ranges (a high end and/or a low end). Then:

- If the water cut value falls within a specified range, the value from the associated WCP is

used for NOC measurements.

- If the water cut falls outside defined ranges, the density-based water cut value is used.

In all cases, the water cut value used in NOC measurements is called the “applied” value.

2.8 Temperature correction

Temperature correction refers to the conversion of the observed process temperature to the equivalent value at reference temperature.

The Net Oil Computer Software automatically applies temperature correction to NOC data. To perform temperature correction, the Net Oil Computer Software requires a value for the current process temperature. This value can be sourced from:

• The RTD built into the Micro Motion sensor

•An external RTD

You must configure the temperature input separately for each NOC Meter in the system.

2.9 Pressure correction

Pressure correction refers to the conversion of the observed process pressure to the equivalent value at reference pressure.

Note: Do not confuse pressure correction with pressure compensation. See Section 2.10 for a definition of pressure compensation.

12 Micro Motion® Net Oil Computer Software and NOC System

NOC System Overview

Pressure correction will be automatically applied to NOC data if pressure data from an external pressure device is input to the Net Oil Computer Software. You must configure the pressure input separately for each NOC Meter in the system.

2.10 Pressure compensation

Pressure compensation refers to the modification of raw mass or density measurements as required to compensate for the effect of pressure on the sensor’s flow tubes.

Note: Do not confuse pressure compensation with pressure correction. See Section 2.9 for a definition of pressure correction.

Pressure compensation for mass or density is implemented in the Net Oil Computer Software, in the MMI Interface and NOC Meter displays.

Note: To avoid applying pressure compensation twice to one set of data, ensure that the pressure compensation factors in the core processor are set to 0 (see the manual entitled Micro Motion Net Oil

Computer Software and NOC System: Installation Manual).

Typically, pressure compensation should be implemented for all Micro Motion sensors in the NOC system. To implement pressure compensation, the following sensor-specific information is required:

• Compensation coefficient for mass flow – the percent change in the flow rate per psi

• Compensation coefficient for density – the change in fluid density, in g/cm

These values are provided in the product data sheet for your sensor. Use the pressure effect values calculated in PSI.

Note: Do not reverse the sign. Unlike other Micro Motion products, the Net Oil Computer Software reverses the sign in its internal calculations.

Note: Not all sensors require pressure compensation. See the sensor’s product data sheet.

2.11 Transient bubble remediation (TBR)

Because density is used to calculate water cut, which is used to calculate net oil, transient bubbles have a negative effect on NOC measurement accuracy. Figure 2-6 shows the effect of transient bubbles on density.

NOC System Overview

Drive gain (%)

Density (measured)

Drive gain (actual)

Figure 2-6 Effect of transient bubbles on density

TBR is used to handle occasional gas bubbles or slugs in the process fluid. A transient bubble condition is defined in terms of the sensor’s drive gain: if the drive gain exceeds the configured threshold for more than three seconds, the configured TBR actions are performed. The transient bubble interval persists until drive gain is below the configured threshold for three seconds.

The Net Oil Computer Software can perform several different actions if transient bubbles are detected:

• Substituting a retrieved density value for the measured density value in NOC calculations (the Correct Density option). This option is described in Section 2.11.1.

• Logging an alarm

• Energizing a discrete output

• All of the above

2.11.1 Correct Density option

The Correct Density option directs the Net Oil Computer Software to retrieve the measured density value from an earlier point in the process. The earlier point is identified by the Lookback Period (see Figure 2-7). The density values from a three-second period around this point are averaged, and this retrieved density average is then used in NOC calculations. Figure 2-8 shows how the Correct Density action affects the density measurement.

Note: If the Lookback Period happens to fall into a previous transient bubble interval, the Net Oil Computer Software automatically extends the lookback interval as required to retrieve an averaged value from measured density values rather than substituted density values.

2.12 Using NOC data

NOC data is stored in the internal history database:

• In Well Test mode, the database can store data for 50 wells, six tests per well. As additional well tests are performed, older tests are overwritten.

• In Continuous mode, data for a single well is stored. In the default configuration, data for the 35 most recent contract periods (typically, days) may be stored. Older data is stored in summary form, and the detailed data is overwritten.

Micro Motion recommends accessing NOC data through the Net Oil Computer Software instead of the ROCLINK 800 history interface. Be sure that you view all required data before it is overwritten. See Chapter 8 for information.

Configuration and Use Manual 15

NOC System Overview

Note: The organization of NOC data in history is designed to support NOC calculations rather than user access. Although you can view data, it is not easy to interpret.

For archival purposes, history data can be retrieved through the ROCLINK 800 history interface. Information on the default history configuration and on accessing history data is provided in the manual entitled ROCLINK 800 Configuration Software: User Manual.

2.13 Using the Recalculation feature

The Recalculation feature is used to convert existing NOC data to:

• Different measurement units

• A different time base

• A different reference temperature

• A different oil density at reference temperature

• A different water density at reference temperature

The Recalculation feature uses the periodic (15-minute) history records. Accordingly:

• You cannot perform recalculation for well tests or contract periods for which no periodic record was written. If the well test or contract period was shorter than 15 minutes, it cannot be recalculated.

• Periodic records are kept in history for ten days. After this time, they are deleted. Be sure to perform all required recalculations while the periodic records are still available.

When a well test or contract period is recalculated, new NOC data can be saved to history if desired. The original NOC data is not overwritten. NOC data produced by recalculation is shown along with the original data on the Well History panel (see Figure 4-21).

Only one set of recalculated data is saved. If you recalculate the same well test or contract period more than once, the most recent recalculated data overwrites the previous recalculated data.

For ease in comparison, the recalculated data is saved to history in the units used for the original data. However, all changes resulting from new values for oil density at reference temperature and water density at reference temperature are preserved.

2.14 Using event and alarm data

The 240 most recent events and 240 most recent alarms are stored in an internal database. Several methods are available for using event and alarm data:

• Contents of the databases can be viewed, printed, saved to a file, or exported for use in an external program.

• A host system can connect to the ROC809 platform and retrieve the data.

Information on accessing event and alarm data is provided in the manual entitled ROCLINK 800 Configuration Software: User Manual. Be sure that you retrieve all required data before it is overwritten.

Configuring the NOC System

Note the following:

• The station name specified here refers to the Net Oil Computer Software running on this ROC809 platform. It is not the same station name that is configured for the device. However, it may be convenient to assign the same tag to both stations.

• The Net Oil Computer Software does not allow you to change measurement units, time base, or reference temperature during a well test. If you change measurement units, time base, or reference temperature during Continuous mode measurement, you will introduce a discontinuity into the data.

If you need to change this information, Micro Motion recommends:

- In Well Test mode, complete the well test, make the required changes, and use the new

measurement units for subsequent tests. Use the recalculation feature (see Section 8.7) to convert existing well test data to different measurement units.

- In Continuous mode, wait until the contract period has expired, or manually force an end

of day (see Section 8.3.2). Make the required changes, then force another end of day and resume data collection. Use the recalculation feature (see Section 8.7) to convert existing data to different measurement units.

Note that if you choose to store the recalculated data on the ROC platform, it will be returned to the original units for ease of comparison. You must manually record the recalculated data if you want to preserve the converted units.

6.3 Configuring water cut measurement using water cut probes (WCPs)

Be sure to configure water cut measurement on all NOC Meters where water cut probes are installed. To configure water cut measurement using one or two water cut probes:

1. Open the Inputs panel of the NOC Meter display (see Section 4.4.2).

2. For

Low WC Probe and/or High WC Probe, specify the analog input used to retrieve data

from the low-end and/or high-end WCP.

3. Using the Water Monitors Limits parameters, specify the range for the WCP(s). For example:

• If

Low is set to 20, the range defined for the low-end WCP is 0 to 20%.

• If

High is set to 80, the range defined for the high-end WCP is 80 to 100%.

If you want to use data from the WCPs for all water cut values, see Examples 1 and 2 in this section and set range values as described in the applicable example.

4. Set

Water Cut Probe Mode to Auto.

5. Set the

Difference Limit value as desired. When Water Cut Probe Mode is Auto, the Net Oil

Computer Software continually compares the density-based water cut value to the WCP value. When the difference is greater than the specified Difference Limit, the software switches from using the density-based value to using the WCP value, or vice versa. See Example 3.

Special Topics in Configuration

Example 3

Two water cut probes are installed. You want to use the low-end probe for all water cut values below 20%, and the high-end probe for all water cut values above 80%.

Configure the water cut parameters as follows:

• Water Monitors Limits: Low: 20

• Water Monitors Limits: High: 80

• Difference Limit: 5

• Water Cut Probe Mode: Auto

At the high end:

• When the density-based water cut value is less than or equal to 80%, NOC measurements are based on the density-based water cut.

• When the density-based value is greater than 80%, the density-based value is compared to the high-end probe value. If the difference is greater than 5, the system will switch to using the water cut value from the probe. The system will continue to use the water cut value from the probe until the density-based value is lower than 80% and the difference is less than 5.

At the low end:

• When the density-based water cut value is greater than or equal to 20%, NOC measurements are based on the density-based water cut.

• When the density-based value is less than 20%, the density-based value is compared to the low-end probe value. If the difference is greater than 5, the system will switch to using the water cut value from the probe. The system will continue to use the water cut value from the probe until the density-based value is greater than 20% and the difference is less than 5.

Density Determination Routines

7.1 About this chapter

This chapter describes the procedures for performing density determination for oil and water.

7.2 About the density determination routines

To derive water cut from measured density values, the Net Oil Computer Software needs two reference values for the well being tested:

• Live oil density at reference temperature

• Water density at reference temperature

Note: These values are not needed if water cut probes will be used for all water cut data.

The density determination routines provided with the Net Oil Computer Software allow you to obtain these values directly from the NOC system in operation.

NOC Special Configuration Using the NOC SystemDensity Determination RoutinesNOC Configuration

The Density Determination panel in the NOC Meter window (see Figure 4-19) is used for density determination. Fields in this panel are listed and defined in Table 4-15.

You cannot perform a density determination while a well test is running, or while the Net Oil Computer Software is in Continuous mode.

7.3 Preparing for density determination

During the density determination for oil, you will need to:

• Pump live oil through a Micro Motion sensor paired with an NOC Meter (see Section 2.4.1), ensuring that the oil contains as little water as possible

• Obtain a sample of the live oil

• Obtain laboratory values for the water cut and the water temperature of the sample

During the density determination for water, you will need to pump free water through a Micro Motion sensor paired with an NOC Meter. If you do not have a sensor installed on a water leg, you can use the instant density value of the process fluid to help determine what fluid is flowing through the sensor. The first fluid flowing through the sensor is typically water from the water layer in the separator, and you should see a stable density value. This process fluid can be used for the density determination of water. As the fluid transitions from water to oil, the density value will fluctuate. When the density value stabilizes again, the fluid flowing through the sensor is oil from the oil layer.

Using the NOC System

8.1 About this chapter

This chapter explains how to use the NOC system via the ROCLINK 800 user interface. The following topics are discussed:

• Operation mode – see Section 8.2

• Using Continuous mode and viewing data – see Section 8.3

• Performing a well test and viewing well test data – see Section 8.4

• Viewing flow and status alarms – see Section 8.5

• Viewing gas data – see Section 8.6

• Using the Recalculation feature – see Section 8.7

NOC Special Configuration Using the NOC SystemDensity Determination RoutinesNOC Configuration

8.2 Operation mode

The NOC system can run in either Continuous mode or Well Test mode:

• In Continuous mode, the NOC system continuously monitors a well, separator, or pipeline. By default, NOC measurement data is written to the history database:

-Every minute

- Every 15 minutes (for some values), or every 60 minutes (for other values)

- At the end of each contract period, as defined by the contract hour or a manual end of day

• In Well Test mode, the NOC system performs NOC measurement on a single well. It is the user’s responsibility to ensure that output from the correct well is routed through the system and that the appropriate purge time is configured. The well test is started and ended manually. During the well test, measurement may be paused and restarted. When the test is ended, well test data is automatically written to the history database.

8.2.1 Changing operation mode

Micro Motion recommends that you perform the initial configuration of the Net Oil Computer Software for the operation mode that will be used, and thereafter change modes as little as possible. However, you can safely change modes at certain points during operation, as described below.

From Continuous to Well Test

To change from Continuous mode to Well Test mode, Micro Motion recommends that you either wait until the end of the current contract period or force an end of day (see Section 8.3.2).

History data for Continuous mode will be overwritten as well tests are performed. Before changing modes, ensure that you have performed all desired recalculations and viewed or retrieved all desired data.

Configuration and Use Manual 75

Using the NOC System

From Well Test to Continuous

If you change from Well Test mode to Continuous mode:

• While a well test is in progress (either running or paused), the current well test is stopped and current well test data is lost.

• When no well test is active, no well test data is lost.

Well test data will be overwritten as Continuous mode records are written. Before changing modes, stop the well test if you need its data, then ensure that you have performed all desired recalculations and viewed or retrieved all desired data.

8.2.2 Managing tags when changing modes

The Net Oil Computer Software uses one set of tags for both well names and contract periods. As a result, you may see contract period dates when you expect to see well names, or vice versa. This effect will appear:

• In the NOC Station General panel

• In the Recalculable Tests Recalc panel

• In all Well Data panels

If you want to reset the tags:

• From well names to contract periods, download the Well Data points from the startup configuration file named NOCStartup_CONTINUOUS.800.

• From contract periods to well names, download the Well Data points from the startup configuration file named NOCStartup_WELLTEST.800.

Note: Downloading other point types will overwrite existing configuration data.

8.3 Using Continuous mode

Continuous mode can measure only Well #01. Before using Continuous mode, ensure that Well #01 is correctly configured for the well that will be measured (see Section 5.4).

8.3.1 Starting Continuous mode measurement

To start Continuous mode measurement:

1. Ensure that the desired stream is flowing through the system.

2. Start ROCLINK 800 and connect to the ROC809.

3. Open the NOC Station display.

4. In the General panel (see Figure 4-2):

a. Set

Operation Mode to Continuous and click Apply.

b. Reconfigure

Contract Hour if desired.

76 Micro Motion® Net Oil Computer Software and NOC System

Using the NOC System

Continuous mode measurement will continue until Operation Mode is switched to Well Test. During Continuous mode measurement:

• The Status field displays the current state of the process.

• Current data is shown in the NOC Station display, the NOC Meter display, and the MMI Interface display (see Section 8.3.4).

• History data is recorded at the configured intervals.

• At the configured contract hour, values are totaled for a single day’s production, totals are reset, and data is logged to the Daily History database.

If Continuous mode measurement is interrupted due to a power failure or power shutoff, the NOC system resumes measurement as soon as power is restored. Visually inspect data for the affected contract period. If appropriate, use Force End of Day (see Section 8.3.2) to start a new contract period, and discard the data from the affected contract period.

8.3.2 Using Force End of Day

The Force End of Day checkbox located on the NOC Station General panel (see Figure 4-2) can be used to perform contract hour actions manually. To do this:

As a result:

• Current daily, hourly, and min/max values will be logged to the history database.

• All totals will be reset.

Note: Do not use the Force End of Day button on the History Segment Configuration window. This button does not write NOC measurement data to history.

8.3.3 Changing parameters during Continuous mode measurement

If you change the well configuration values, measurement units, reference temperature, or time base during a contract period, the changes are not applied to existing data. As a result, you will introduce discontinuities into the data for that contract period. If you need to change any of these values:

1. Force an end of day (see Section 8.3.2).

2. Reconfigure as required.

3. Force a second end of day.

4. Discard measurement data for the contract period used for reconfiguration.

If you need to apply different reference values or measurement units to existing data, use the Recalculation feature (see Section 8.7).

Configuration and Use Manual 77

• The Modbus interface on the ROC809 platform – see Section 9.3

9.2 History on the ROC809 platform

Although you can view NOC data through the history function, Micro Motion recommends using the Net Oil Computer Software to view NOC data. The Net Oil Computer Software compiles and presents NOC data in a more usable form (see Sections 8.3.4, 8.3.5, 8.4.3, and 8.4.4).

However, you may want to add history points to the default history configuration. Note the following:

• Three history segments have been predefined by the Net Oil Computer Software: General 00, Segment 01, and Segment 02. Most of the General 00 segment and all of Segment 01 are used for internal processing. Part of the General 00 segment and all of Segment 02 are available for site use. See Table 9-1. Do not change any history that is reserved by the Net Oil Computer Software. If you do, the NOC system will not function correctly.

9.3 Modbus interface on the ROC809 platform

For general information on the Modbus interface provided by the ROC809 platform, see the manual entitled ROCLINK 800 Configuration Software: User Manual.

If you want to use the Modbus interface, note the following:

• Because NOC data is not stored in standard history, the Modbus History window is not used for access to NOC data. The Modbus History window is used only to define the date, time, and event/alarm log indexes. In most cases, the default values should be used.

• The NOCStartup.800 configuration file includes predefined Modbus register ranges that provide access to most of the Net Oil Computer Software data, including process data, unit data, and some configuration data. All of the predefined register ranges have been defined for use by any comm port. You can modify the predefined register ranges if you wish: NOC system operation will not be affected.

9.3.1 Predefined Modbus register ranges
