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.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.

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

EndPointScalingCoefficients(phases::Symbol; drainage = true)

Parameters that represent end-point scaling for a relative permeability phase (drainage or imbibition) as parametrized by four points (connate, critical, saturation at which maximum kr first occurs and maximum kr).

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.
