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.

Gross or gross @ ref The sum of the oil volume and the water volume, as measured by the NOC

application.

oil shrinkage factor applied.

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

The NOC application derives the water cut by applying the following equation:

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.

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%.
