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.

defined on the ROC809 platform using standard ROCLINK methods. The ROC809 gas station
applies AGA (or other) calculations to the gas data, and the results are input to the NOC Gas
Station in the Net Oil Computer Software. The Net Oil Computer Software reports the gas data
but does not perform any additional processing.

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

Density (measured)

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.
