Grid model static

This exports a static grid model with standard properties from within RMS.

The following properties will be included in the exported grid model:

  • zonation

  • regions

  • porosity

  • permeability

  • saturation_water

  • fluid_indicator

  • bulk_volume_oil and/or bulk_volume_gas

The following properties can optionally be included:

  • facies

  • net_to_gross

  • permeability_vertical

  • volume_shale

Note

It is possible to omit one of bulk_volume_oil or bulk_volume_gas if that fluid is not present in the field.

Property descriptions

class PropertyAttribute[source]

Known property attributes.

zonation = 'zonation'

Classification of geological zonations within the reservoir.

regions = 'regions'

Classification of distinct geographic regions in the field.

facies = 'facies'

Classification of rock types influencing reservoir properties.

net_to_gross = 'net_to_gross'

Classification of net-to-gross ratio within the reservoir.

fluid_indicator = 'fluid_indicator'

Presence indicator for specific fluids (e.g., oil/gas/water) in the reservoir.

porosity = 'porosity'

The fraction of the rock volume that is pore space.

permeability = 'permeability'

Measure of how easily fluids flow.

permeability_vertical = 'permeability_vertical'

Measure of how easily fluids flow in the vertical direction.

saturation_water = 'saturation_water'

The fraction of the pore space occupied by water.

volume_shale = 'volume_shale'

The fraction of the rock volume that is shale.

bulk_volume_oil = 'bulk_volume_oil'

The bulk volume of oil in the rock.

bulk_volume_gas = 'bulk_volume_gas'

The bulk volume of gas in the rock.

Requirements

  • RMS

  • grid model in RMS containing standard properties

  • bulk volume fluid properties with names Oil_bulk and/or Gas_bulk (as applicable)

  • fluid indicator property with name Discrete_fluid

The grid model needs to be located in RMS and contain standard properties.

For most properties, the RMS property name is provided as function input. The bulk_volume_oil, bulk_volume_gas, and fluid_indicator properties are however detected automatically and must exist in the grid with these exact RMS names: Oil_bulk, Gas_bulk and Discrete_fluid.

This export function will validate that the properties are of expected type and have values within expected ranges e.g. a porosity property must have values between 0 and 1.

Tip

The easiest way to produce the bulk_volume_oil or bulk_volume_gas properties is to enable Parameter output from Bulk in the volumetrics job in RMS. The Discrete_fluid property can be output from the same job by enabling the Create discrete fluid parameter.

Usage

export_grid_model_static(project, gridname, zonation, regions, porosity, permeability, saturation_water, facies=None, net_to_gross=None, volume_shale=None, permeability_vertical=None)[source]

Simplified interface when exporting a grid model with common properties from RMS.

Parameters:

  • project (Any) – The ‘magic’ project variable in RMS.

  • gridname (str) – Name of the grid model.

  • zonation (str) – Name of the zone property.

  • regions (str) – Name of the regions property.

  • porosity (str) – Name of the porosity property.

  • permeability (str) – Name of the permeability property.

  • saturation_water (str) – Name of the water saturation property.

  • facies (str | None) – Name of the facies property.

  • net_to_gross (str | None) – Name of the net to gross property.

  • volume_shale (str | None) – Name of the volume shale property.

  • permeability_vertical (str | None) – Name of the vertical permeability property.

Examples

Example usage in an RMS script:

from fmu.dataio.export.rms import export_grid_model_static

export_results = export_grid_model_static(
    project,
    gridname="Geogrid",
    zonation="Zone",
    regions="Region",
    porosity="PHIT",
    permeability="KLOGH",
    saturation_water="SW",
    facies="FACIES",
    )

for result in export_results.items:
    print(f"Exported item to {result.absolute_path}")

Result

The grid and its properties will be exported as separate files of type ‘roff’ to share/results/grids/grid_model_static/gridname.roff and gridname--propertyname.roff.
