XML Element: SinglePhaseWell

Name	Type	Default	Description
allowNegativePressure	integer	1	Flag indicating if negative pressure is allowed
control	geos_ConstraintTypeId	required	Well control. Valid options: * BHP * phaseVolRate * totalVolRate * massRate * uninitialized
enableCrossflow	integer	1	Flag to enable crossflow. Currently only supported for injectors: - If the flag is set to 1, both reservoir-to-well flow and well-to-reservoir flow are allowed at the perforations. - If the flag is set to 0, we only allow well-to-reservoir flow at the perforations.
enableIsoThermalEstimator	integer	0	Flag to enable isothermal estimator prior to coupled reservoir and well solve.
estimateWellSolution	integer	0	Flag to esitmate well solution prior to coupled reservoir and well solve.
initialPressureCoefficient	real64	0.1	Tuning coefficient for the initial well pressure of rate-controlled wells: - Injector pressure at reference depth initialized as: (1+initialPressureCoefficient)*reservoirPressureAtClosestPerforation + density*g*( zRef - zPerf ) - Producer pressure at reference depth initialized as: (1-initialPressureCoefficient)*reservoirPressureAtClosestPerforation + density*g*( zRef - zPerf )
logLevel	integer	0	Sets the level of information to write in the standard output (the console typically). Information output from lower logLevels is added with the desired log level 1 - Well control information
name	groupName	required	A name is required for any non-unique nodes
referenceReservoirRegion	groupNameRef		Name of reservoir region used for obtaining average region pressure used in volume rate constraint calculations. Frequency of pressure update is set in SinglePhase/CompositionalMultiphaseStatistics definition. Setting cycleFrequency=’1’ will update the pressure every timestep, note that is a lagged property in constraint propertiesNote the event associated with the statists task must be entered before the solver event.
statusTableName	groupNameRef		Name of the well status table when the status of the well is a time dependent function. If the status function evaluates to a positive value at the current time, the well will be open otherwise the well will be shut.
surfacePressure	real64	0	Surface pressure used to compute volumetric rates when surface conditions are used [Pa]
surfaceTemperature	real64	0	Surface temperature used to compute volumetric rates when surface conditions are used [K]
timeStepFromTables	integer	0	Choose time step to honor rates/bhp tables time intervals
type	geos_WellControls_Type	required	Well type. Valid options: * producer * injector
useSurfaceConditions	integer	0	Flag to specify whether rates are checked at surface or reservoir conditions. Equal to 1 for surface conditions, and to 0 for reservoir conditions. See note on referenceReservoirRegion for reservoir condition options
writeCSV	integer	1	When set to 1, write the rates into a CSV file.
