(Absolute) Minimum well rate for a well that is not disabled.

(Absolute) Minimum initial rate for wells when controls are updated.

Constrained pressure residual

DisabledControl()

Control that disables a well. If a well is disabled, it is disconnected from the surface network and no flow occurs between the well and the top side. Mass transfer can still occur inside the well, and between the well and the reservoir.

See also ProducerControl, InjectorControl.

DisabledTarget(q)

Disabled target used when a well is under DisabledControl() only.

A single saturation that represents the "other" phase in a three phase compositional system where two phases are predicted by an EoS

InjectorControl(target, mix, [density])

Well control that specifies injection into the reservoir. target specifies the type of target and mix defines the injection mass fractions for all species in the model during injection.

For example, for a three-component system made up of CO2, H2O and H2, setting [0.1, 0.6, 0.3] would mean that the injection stream would contain 1 part CO2, 6 parts H2O and 3 parts H2 by mass. For an immiscible system (e.g. LiquidPhase(), VaporPhase()) the species corresponds to phases and [0.3, 0.7] would mean a 3 to 7 mixture of liquid and vapor by mass.

The density of the injected fluid at surface conditions is given by density which is defaulted to 1.0 if not given.

MinimalTPFAGrid(ϕ, N)

Generate a minimal grid suitable only for two-point flux discretization (TPFA) for given pore-volumes ϕ and a neighborship matrix N with size (2, n) where n is the number of internal faces.

Two point approximation with flux for wells

Perforations are connections from well cells to reservoir vcells

Mass density of each phase

Pressure

ProducerControl(target)

Well control for production out of the reservoir. target specifies the type of target (for example BottomHolePressureTarget()).

replace_target(ctrl, new_target)

Create new well control using ctrl as a template that operates under new_target.

simulate_mrst_case(file_name; kwarg...)

Simulate a MRST case from file_name as exported by writeJutulInput in MRST.

Arguments

• file_name::String: The path to a .mat file that is to be simulated.
• extra_outputs::Vector{Symbol} = [:Saturations]: Additional variables to output from the simulation.
• write_output::Bool = true: Write output (in the default JLD2 format)
• output_path = nothing: Directory for output files. Files will be written under this directory. Defaults to the folder of file_name.
• write_mrst = true: Write MRST compatible output after completed simulation that can be read by readJutulOutput in MRST.

Additional input arguments are passed onto sensible subroutines.
