`WINJTEMP`

Recognised by the OPM Flow parserSCHEDULE

WINJTEMP defines the injection fluid thermal properties for when the thermal option has been activated by the THERMAL keyword in the RUNSPEC section. Only water and gas injection is supported.

This keyword can only be used if OPM Flow’s thermal option has been activated by the THERMAL keyword in the RUNSPEC section. Note this is different to the commercial simulator that uses the TEMP keyword in the RUNSPEC section to activate the black-oil thermal model.

Notes:

The keyword is followed by any number of records with each record terminated by a “/” and the keyword should be terminated by a “/”.

Records: One or more records, each terminated by /
Items per record: 5

Parameters

No.	Name	Description	Type	Dimension	Field	Metric	Lab	Default
1	`WELL` manual: `WELNAME`	A character string of up to eight characters in length that defines the well name for which the well injection fluid thermal properties are being defined. Note that the well name (WELNAME) must have been declared previously using the WELSPECS keyword in the SCHEDULE section, otherwise an error may occur.	STRING					None
2	`STEAM_QUALITY` manual: `STEAMQAL`	STEAMQAL is a real positive value greater than or equal to zero and less than or equal to one that defines the steam quality of the injected fluid for the defined well. This parameter should be defaulted using 1* as STEAMQAL is not used by OPM FLOW, as only water and gas injection is supported. This data is used by the commercial simulator’s THERMAL option and is not supported by OPM Flow’s THERMAL option.	DOUBLE		dimensionless	dimensionless	dimensionless	1*
3	`TEMPERATURE` manual: `TEMP`	TEMP is a real positive value that defines the temperature of the injected fluid for the defined well.	DOUBLE	Temperature	°F	°C	°C	None
4	`PRESSURE` manual: `PRES`	PRES is a real positive value that defines the pressure of the injected fluid for the defined well.	DOUBLE	Pressure	psia	barsa	atma	None
5	`ENTHALPY`	ENTHALPY is a real positive value that defines the specific enthalpy of the injected fluid for the defined well. This is data is used by the commercial simulator’s THERMAL option and is not supported by OPM Flow’s THERMAL option.	DOUBLE	Energy/Mass	Btu/lbs-M	kJ/kg-M	J/gm-M	None

Example

The following example shows the WINJTEMP keyword for when OPM Flow’s temperature option has been activated by the THERMAL keyword in the RUNSPEC section.
--
-- INJECTION FLUID THERMAL PROPERTIES
--
-- WELL STEAM INJ INJ SPEC
-- NAME QUAL TEMP PRES ENTH
WINJTEMP
WI01 1* 68.0 220.0 1* /
WI02 1* 70.0 230.0 1* /
/
Here the water injection fluid’s temperature and pressure, in field units, for two water injections well are defined. Notice that both the steam quality and the specific enthalpy of the injected fluid for the defined wells are defaulted (or skipped), as OPM Flow’s THERMAL option does not support this data.
