2.1 NOC overview

NOC is a software option that customers can purchase for the Model 5700 transmitter.

The NOC application can provide real-time measurements of water cut when paired with a Micro Motion
sensor installed on either of the following options:

• The oil or water leg of a two-phase separator

• The oil leg of a three-phase separator

Alternatively, the NOC application can receive water cut data from an external water cut monitor. When the
water cut value is known, net oil volume flow and net water volume flow can be calculated.

Net oil volume flow and net water volume flow can also be calculated by the Advanced Phase Measurement
software from current density data.

All volume rates and totals are at line conditions, uncorrected, unless stated otherwise.

2.2 NOC terminology

Term Definition

Actual The flow rate as measured at the time of viewing.

Average The flow-weighted average, calculated from the beginning of the applicable

time period.

Back flow Uncorrected volume flow that is moving backward through the sensor.

2.3 NOC system components

The Model 5700 NOC system requires:

• One Model 5700 transmitter with the NOC software option

• One Micro Motion sensor installed on the oil and water, or oil leg

• (Optional) A water cut monitor on the oil and water, or oil leg

2.4 Installation architecture

You can install the Model 5700 NOC system with a two-phase separator, or a three-phase separator.

Note

The following examples do not illustrate all possible combinations.

NOC system with a two-phase separator

With a two-phase separator, the NOC system uses density-based water cut data.

A. Model 5700 transmitter

B. Separator
C. Oil/water leg
D. Sensor

NOC system with a three-phase separator

With a three-phase separator:

• A meter is installed on the water leg, but the Model 5700 transmitter does not monitor or record flow data

from this source.

• A water cut monitor is installed on the oil leg. The NOC system can be configured to use either density-

based water cut data, or data from the water cut monitor.

2.5 Operation modes

The NOC system operates in either well test mode or continuous mode.

You can change modes after initial configuration. However, changing modes affects current measurement
and data collection.

Well test mode

Well tests can be performed on up to 48 wells. A manifold system is used to ensure that output from a single
well is routed through the test separator and the NOC system. The system can save data for a total of three
well tests. If more than three tests are run, older tests are overwritten as required.

2.6 Required well data

The following information is required for each well tested or measured by the NOC system:

• Density of dry oil from this well at reference temperature and reference pressure. To ensure the most

accurate net oil data, the density should be based on live oil rather than dead oil. “Live oil” refers to crude
oil at line pressure.

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

If you do not know the density values, do any of the following tasks:

• Take samples of produced oil and produced water, perform laboratory analysis, and enter the results into

the well configuration.

• Perform an in-line density determination for oil, water, or both. During in-line density determination, the

appropriate process fluid (water or live oil) is routed through the sensor, density values are averaged over a
user-specified time period, and these values are converted to reference temperature. The water cut
calculation uses these average values for DO and DW.

• Enter approximate values at initial configuration, begin measurement, and recalculate NOC data at a later

time when well-specific density values are known.

2.7 Water cut determination

There are two options for determining water cut, density-based and water cut monitoring.

Density-based

Water cut monitoring (external water cut)

A water cut monitor is used to measure the process stream directly. The Model 5700 transmitter retrieves the
water cut data via a HART connection. A HART connection between the primary mA output on the NOC
platform and the water cut monitor is required.

The Model 5700 can also use external water cut using an mA Input.

2.8 NOC features and options

This section describes several features and options of the NOC application.

2.8.1 Temperature correction

Temperature correction refers to the conversion of data collected at the observed process temperature to the
equivalent values at reference temperature. The NOC application automatically applies temperature
correction to NOC data, using the temperature data from the RTD built into the sensor.

2.8.2 Shrinkage factors

Shrinkage is a reduction in mass and volume of crude oil due to the vaporization and evaporation of the
volatile components in the oil. By estimating the shrinkage during oil storage or transport, you can estimate
sellable oil based on upstream volume measurement.

Note

The contraction of the volume due to cooling is not a mass loss. It is the thermal contraction of the oil
accounted for by “temperature correction” via the Volume Correction Factors in API Ch 11.1.

The NOC application includes one shrinkage factor for oil. The net oil flow rate measured by the NOC
application is automatically multiplied by the corresponding shrinkage factor and output on a separate PV. By
default, the shrinkage factors are set to 1.0, resulting in no compensation for shrinkage.

Use your standard methods to determine the appropriate shrinkage factors, taking into consideration the
location of the sensor in your process.

2.8.3 Liquid with gas

This measurement option improves flow measurement in liquid processes with intermittent entrained gas.

Note

The liquid with gas measurement option can also be combined with the net oil measurement option or
concentration measurement. See the Micro Motion Enhanced Density Application Manual to configure
concentration measurement.

Liquid with gas measurement process

The presence of entrained gas (or bubbles) can cause significant errors when measuring the volume flow of
liquid through a Coriolis meter. Because bubbles displace some of the liquid in a flow stream, the measured
volume of the mixture may differ from the actual amount of liquid that emerges from the pipe downstream.

So how can you tell when a liquid contains gas? When bubbles are present in a liquid stream, Coriolis meters
will report an increase in drive gain coinciding with a decrease in both fluid density
due to the lower amount of mass contained in the liquid-gas mixture. Therefore, in order to measure only the
liquid portion of the stream, the volume of the bubbles must be ignored or subtracted from the mixture total.

(1)

and mass flow rate

(2)

(1) High frequency sensors may erroneously report a higher fluid density when entrained gas is present, and therefore are not

recommended for use on liquids with entrained gas. High frequency sensors include the F300/H300 compact, and all T­Series sensors.

(2) The accuracy and repeatability of the mass flow and density measurements for liquids with entrained gas is dependent on

the sensor-fluid decoupling ratio, which is a complex function of fluid velocity, fluid viscosity, fluid density, the difference
between the liquid and gas densities, the operating sensor frequency, and the Gas Volume Fraction (GVF) of gas. For best
measurement performance, GVF should be kept below 15%.

12 Micro Motion® Model 5700 Transmitter

Multiwell Supplement

MMI-20052554 March 2019

The Advanced Phase Measurement software with NOC performs exactly this function, using drive gain as the
diagnostic indication that bubbles or entrained gas is present in the liquid flow stream, and then substituting
a liquid-only density in place of the live measurement until the gaseous event has subsided. When the gassy
portion has passed, indicated by an associated drop in drive gain, the software returns to reporting the live
measured volume flow rate.

B. Measured density
C. Entrained gas ocurring during these intervals
D. Drive gain threshold

Entrained gas in liquids affects drive gain and density measurement. The green line (A) shows the drive gain
indication which is stable under most single-phase conditions. However, if gas is entrained in the liquid, the
density reading (B) will drop and the drive gain reading will increase. When the entrained gas bubbles go
away, the drive gain will return to its normal indication and the density measurement will reflect the density
of the liquid.

The Advanced Phase Measurement software with NOC identifies entrained gas in liquid flow by detecting the
sharp increases in drive gain and corresponding decreases in density measurement. The software
continuously monitors the most recent drive gain data (up to 60 minutes) to determine drive gain threshold.
If the measurement exceeds the drive gain threshold, the fluid is deemed to contain entrained gas, and
remediation occurs.

The drive gain threshold can also be entered manually. For details about drive gain thresholds, see B-4 or B-5.

Production type options

Continuous Flow

Select this option only when flow rates are expected to be stable under normal operating conditions. The
Advanced Phase Measurement software with NOC assumes the liquid properties and flow velocity through

the pipe is constant, and hence is able to remediate the mass flow values in addition to density and volume
values.

Variable Flow (default)

Select this option when flow rates are not stable, for applications such as batching, dump valve control, beam
pumps, or other variable processes. When variable flow is selected, APM will remediate only density and
volume variables.

Multiwell Supplement

Remediation options (APM Action)

If the drive gain threshold is exceeded, you must select one of the following methods to handle the volume
calculation for the period of high drive gain.

Hold Last Value (default)

APM will use a held density value from an earlier point in the process to report density, calculate volume, and
calculate any other density-influenced variables during remediation. If this option is chosen, the density from
the point just before the entrained gas event is held constant throughout the event.

This figure shows how the Hold Last Value feature works in APM. The green line (A) shows the drive gain value
and the blue line (B) shows the density reading. If the liquid gets entrained with gas bubbles, the drive gain
increases above the drive gain threshold (D). Then the software determines a density value from recent
process data that does not have a high drive gain. It then substutes that value for the measured density until
the drive gain goes back below the threshold value (D). This substituted density is also referred to as the
remediated density.

Multiwell Supplement Planning

MMI-20052554 March 2019

Density Hold Override

APM will use a user-input density value from an earlier point in the process to report density, calculate
volume, and calculate any other density-influenced variables during remediation. This value should reflect the
density of the liquid at line conditions.

2.9 Configuration checklist

This section contains questions that you should answer before beginning basic configuration of the Net Oil
Computer Software and the NOC system.

Note

These questions are specific to implementing the NOC system and do not address basic system configuration
(for example, configuring the clock, passwords, events, communications, etc.).

• Will this system be used to test multiple wells or to perform continuous measurement of a single well?

• If it will be used for well testing, what wells will be tested? in what order?

• Will you use density-based water cut data or a water cut monitor? If you are using a water cut monitor,

what is its range?

• For all wells that will be measured:
— What is the oil density at reference temperature? If not known, will you perform a density

determination?

— What is the water density at reference temperature? If not known, will you perform a density

determination?

— (For Well Test mode only) What is each well’s purge time?

• Will you use HART communications for water cut data? If yes:
— What are the HART tags of the external devices?

— Is the primary mA Output wired to support HART communications with the external devices?

• If you will configure shrinkage factors, what values will you use?

3.3 Set up Transient Bubble Remediation

Procedure

1. Go to Menu > Configuration > Process Measurement > Well Performance Meas > Compensations.

2. Set Remediation Action to Hold Last Value.

The transmitter will calculate volume using a substitute density value. The substitute value is an
average of the data around a recent point in the process.

3. Optional: Configure a Discrete Output to report APM status.
See Basic configuration procedure.

3.4 Density determination

If you are performing a density determination for oil and for water, it is more convenient to perform density
determination for water first.

At any point during the procedures in this section, you can discard the data and stop the density
determination process by selecting Cancel or by navigating left to return to other functions.

3.4.1 Density determination for water

There are two density determination methods for water: in-line and manual. This section provides
instructions for both methods.

The in-line method requires enough water in the separator to supply a stable flowing density for the density

See Basic configuration procedure.

6. Monitor the density and temperature values, watching for the density and temperature readings to
stabilize.

7. Optional: Highlight Volume Total Reset and navigate to the right. If you reset this total when the
separator first started to flow, i.e. when you were doing the water density determination, you can
monitor the amount of fluid to reset the volume total to 0. Select Continue to confirm resetting the
volume total.This enables you to monitor the amount of fluid that remains in the separator, if the
separator volume is known.

8. When the density and temperature readings have stabilized, highlight Start and navigate to the right.
The NOC application will now average the density and temperature of the process fluid for the
specified oil averaging duration. If the drive gain exceeds the limit, then the Oil Deviation Limit
Exceeded screen displays. From this screen, you have the option to continue the save process or
discard the data and restart the density determination process.

Note

If the Oil Deviation Limit Exceeded displays, you might need to stabilize your process fluid or increase
the Drive Deviation value.

9. If you are using the density-based water cut, take a sample of the fluid in the pipe during this averaging
period, then measure the sample water cut. You can use any standard procedure, such as centrifuge,
distillation, Karl-Fischer, etc., to measure the water cut. Measure in % volume.

If you are using a water cut monitor, this sampling procedure is optional. You can use either the water
cut data measured by the monitor or water cut data from the sample.

Important

The accuracy of the water cut value directly affects the accuracy of the NOC data. Use a representative
sample and measure carefully. Some medium and light oil samples may have negligible entrained
water.

10. When the averaging process is complete, you can can save or discard the data (cancel). Select
Continue to confirm resetting the volume total.

A save will replace the stored value with the new value.
