Parameters

General

JutulDarcy.FluidVolume Type

FluidVolume()

Variable typically taken to be a parameter. Represents the per-cell volume that where multiphase flow can occur. For a well, this is the volume inside the well-bore free flow can occur. For a porous medium, this is the void space inside the pores that is, to some extent, connected and open to flow (effective pore-volume).

Reservoir parameters

Transmissibility

JutulDarcy.Transmissibilities Type

Transmissibilities()

Variable/parameter used to define the cell-to-cell transmissibilities when using a two-point flux approximation scheme.

source

JutulDarcy.Diffusivities Type

Diffusivities()

One diffusive face conductance per component. Use the parameter names LiquidDiffusivities, VaporDiffusivities, and AqueousDiffusivities for phases present in the model. The corresponding data-domain keys are liquid_diffusion on cells or liquid_diffusivities on faces, with the same prefixes for vapor and aqueous phases. Matrices have one row per component, in the system's component order. Coefficients use the mole-fraction Fick law. Black-oil diffusion requires component molar masses in kg/mol as component_molar_masses on nothing in the data domain.

Unprefixed diffusion and diffusivities retain the pre-0.4 JutulDarcy per-phase format; each phase row is expanded over components during parameter initialization.

JutulDarcy.reservoir_transmissibility Function

reservoir_transmissibility(d::DataDomain)
reservoir_transmissibility(d::DataDomain; version = :xyz)

Special transmissibility function for reservoir simulation that handles additional complexity present in industry grade models such as fault multipliers, net-to-gross etc. The input should be a DataDomain instance returned from reservoir_domain

The keyword argument version can be :xyz for permeability tensors that are aligned with coordinate directions or :ijk to interpreted the permeability as a diagonal tensor aligned with the logical grid directions. The latter choice is only meaningful for a diagonal tensor. The :ijk option will be automatically selected automatically if the :ijk_permeability flag is set in the domain (d[:ijk_permeability, NoEntity()] = true).

Other

JutulDarcy.TwoPointGravityDifference Type

TwoPointGravityDifference()

Parameter representing the difference in gravity on an instance of Faces between two Cells. If the phase flux is written as

$v=-K\mathrm{\nabla }(p+\rho g\mathrm{\nabla }z)$

this term represent the discretized analogue of $\rho g\mathrm{\nabla }z$.

source

JutulDarcy.ConnateWater Type

ConnateWater()

Parameter for connate water per cell. Used in some three-phase relative permeability evaluators.

source

JutulDarcy.EndPointScalingCoefficients Type

Type that defines endpoint scaling parameters for relative permeabilities (either drainage or imbibiton).

source

Well parameters

JutulDarcy.WellIndices Type

WellIndices()

Parameter for the connection strength between a well and the reservoir for a given perforation. Typical values come from a combination of Peaceman's formula, upscaling and/or history matching.

source

JutulDarcy.PerforationGravityDifference Type

PerforationGravityDifference()

Parameter for the height difference from the wellbore and the connected node in the well.

source

Thermal

JutulDarcy.FluidThermalConductivities Type

FluidThermalConductivities()

Variable defining the fluid component conductivity.
