Advanced model example
This is a model very similar to Simple example. The main difference is the use of more advanced energy usage models and consumer systems, and the addition of a second installation.
Both installations exports oil (OIL_PROD) and gas (GAS_PROD).
The installations emit CO2 and CH4.
The following is an example with one installation called Installation A and Installation B.
The results of a performed characterization of the equipment are listed below:
| Consumer | Type | Description |
|---|---|---|
| Generator set A | Generator set | Variable fuel consumer with electricity to fuel function |
| Base production load A | Power consumer | Production base load varying depending on a binary condition |
| Gas export compressor A | Power consumer | Variable consumption depending on gas sales rate |
| Produced water reinjection pump A | Power consumer | Variable consumption depending on water production rate and water injection rate. The pump suction pressure is 10 bar and discharge pressure is 200 bar. |
| Sea water injection pump A | Power consumer | Variable consumption depending on a complex combination on water injection rate and water production rate |
| Flare A | Direct fuel consumer | Flare A |
| Generator set B | Generator set | Variable fuel consumption with electricity to fuel function |
| Base production load B | Power consumer | Production base load at 7.6 MW |
| Gas export compressor B | Direct fuel consumer | Variable fuel consumption depending on gas sales rate |
| Flare B | Direct fuel consumer | Flare B |
YAML model overview
The YAML model consist of these main components:
- Time series inputs - TIME_SERIES
- Facility characterization input - FACILITY_INPUTS
- Fuel input - FUEL_TYPES
- Model specifications - MODELS
- Model variables - VARIABLES
- Installation topology - INSTALLATIONS
The YAML setup file looks like this:
TIME_SERIES:

FUEL_TYPES:

We will now replace the placeholders for each of the main keywords above.
TIME_SERIES
The reservoir variables, in this case, are found in a CSV (Comma separated file) production_data.csv.
We give the time-series data a name that can be referenced as variables elsewhere in the form <NAME>:<NAME OF COLUMN>.
See TIME_SERIES for further details.
TIME_SERIES:
- NAME: SIM
TYPE: DEFAULT
FILE: base_profile.csv
FACILITY_INPUTS
We specify CSV input data for processing equipment using FACILITY_INPUTS. This is used for generatorsets, tabulated/sampled models and pump charts. See FACILITY_INPUTS for further details.
Here we define a tabulated genset, a sampled compressor, and a single speed pump chart. Note that more complicated energy models are defined under the MODELS-keyword.

FUEL_TYPES
In this example there are two FUEL_TYPES - fuel_gas and bad_fuel_gas.
These are used for Installation A and Installation B respectively.
Here we also define emissions in CO2 and CH4:

VARIABLES
To run the model it is recommended to specify VARIABLES, instead of hard coding values in difference places. This makes it easier to develop, maintain and understand the model by allowing descriptive variable names and avoid duplications.
For our model, we specify the following variables:
VARIABLES:
hydrocarbon_export_sm3_per_day:
VALUE: SIM;OIL_PROD {+} SIM;GAS_PROD {/} 1000
gas_export_rate_sm3_per_day:
VALUE: SIM;GAS_PROD
water_injection_rate:
VALUE: SIM;WATER_INJ
gas_export_condition:
VALUE: SIM;GAS_PROD > 0
base_production_load_mw:
VALUE: 7.6 {+} 4.1 {*} (SIM;GAS_LIFT > 0)
water_injection_condition:
VALUE: SIM;WATER_PROD >0
flare_a_fuel_rate_sm3_day:

2030-01-01:

flare_b_fuel_rate_sm3_day:
2020-06-01:
VALUE: 10000
2030-01-01:
VALUE: 7000
pea:
VALUE: 0.95 # 0.87
peb:
VALUE: 0.95
gasratea_cd:
VALUE: $var.gas_export_rate_sm3_per_day {*} $var.pea
gasrateb_cd:
VALUE: $var.gas_export_rate_sm3_per_day {*} $var.peb
winjratea_cd:
VALUE: $var.water_injection_rate {*} $var.pea
hcexpa_cd:
VALUE: $var.hydrocarbon_export_sm3_per_day {*} $var.pea
hcexpb_cd:
VALUE: $var.hydrocarbon_export_sm3_per_day {*} $var.peb
We reference the TIME_SERIES SIM using the column names from the CSV file.
You can use boolean condition such as shown in base_production_load_mw and time varying variables such as shown in flare_a_fuel_rate_sm3_day and flare_b_fuel_rate_sm3_day to write simpler models with less duplicated code.
The base_production_load_mw adds another 4.1 MW when the gas lift injection rate is positive.
The flare rate changes in year 2030.
INSTALLATIONS
An installation is composed of hydrocarbon export, a default fuel for that installation and consumers in the form of generatorsets (with electric sub-consumers), and direct fuel consumers.
We specify:
NAME: the installation nameHCEXPORT: Hydrocarbon export in Sm3/day by referring to the variable $var.hydrocarbon_export_sm3_per_day specified under VARIABLES above.FUEl: Default fuel specified in FUEL_TYPES above. Note the different fuels used by the two installations.CATEGORY: FIXED (installation) category is used to group result data for reporting. See CATEGORY for details.REGULARITY: Defined by the variable $var.pea specified under VARIABLES above.REGULARITYis closely related to the production efficiency (PE) of a facility, and is used to convert between stream day (sd)- and calendar day (cd) rates.

Installation A
There is one generator set, Generator set A. This has a power to fuel function defined in
FACILITY_INPUTS with the name genset. Further, the consumers getting
power from the generator set are Base production load, Gas export compressor, Produced water reinjection pump
and Water injection pump.
The direct fuel consumers are Flare.

ENERGY_USAGE_MODEL
We will now fill in the final placeholders with detailed ENERGY_USAGE_MODELs.
Fixed production loads A has a load of 7.6 MW with additional 4.1 MW when the field gas injection rate is positive:
- NAME: Fixed production loads A
CATEGORY: FIXED-PRODUCTION-LOAD
ENERGY_USAGE_MODEL:
TYPE: DIRECT
LOAD: $var.base_production_load_mw
CONSUMPTION_RATE_TYPE: STREAM_DAY # (This is default)
Gas export compressor system A is represented by a consumer system of two simplified compressor train models.
The system has defined the variable gasratea_cd and will run two different
rate distributions between these two compressor trains. It will first send all rate to the first compressor train
and nothing to the second RATE_FRACTIONS: [1.0, 0.0] and then it will run the same input while distributing equal
rates to the two compressor trains RATE_FRACTIONS: [0.5, 0.5]. The final result will be composed of the first
setting that returns a valid result for the compressors.
See COMPRESSOR_SYSTEM for further details.
The compressor model is then defined:
- NAME: Gas export compressors system A
CATEGORY: COMPRESSOR
ENERGY_USAGE_MODEL:
TYPE: COMPRESSOR_SYSTEM
COMPRESSORS:
- NAME: train1_A
COMPRESSOR_MODEL: simplified_compressor_train_model

- RATE_FRACTIONS: [0.5, 0.5]

DISCHARGE_PRESSURE: 120
Water injection pump system A is variable and its energy function is dependent on the field's water
injection rate (WATER_INJ) that is set in the variable water_injection_rate as SIM;WATER_INJ.
The pump only runs when the variables water_injection_condition evaluates to true as SIM;WATER_PROD > 0.
This is when the water injection rate is positive. Fluid density, suction pressure and discharge pressure
is also defined.
This PUMP_SYSTEM behaves much the same as the COMPRESSOR_SYSTEM above. See PUMP_SYSTEM for further details.

Single pump A has an energy function that is dependent on the seawater injection rate, same as the system above.
It uses the pump_chart defined in FACILITY_INPUTS above.
The pump model is then defined:

The Flare A is changing on the 1st of July 2020 and 1st of January 2030. Therefore, we need to use a different constant
fuel consumption value before and after this date. This is done using the variable flare_a_fuel_rate_sm3_day.
The model becomes:
