`WSOLVENT`

Recognised by the OPM Flow parserSCHEDULE

WSOLVENT defines a gas injection well’s solvent fraction in the injection stream that is to be used when the Solvent option has been activated by the SOLVENT keyword in the RUNSPEC section.

Notes:

User Defined Quantities ("UDQ") can be used as User Defined Arguments ("UDA") for various group, well, and connection keywords in the SCHEDULE section. User Defined Arguments are activated using the UDADIMS keyword in the RUNSPEC section, and defined by the UDQ keyword in the SCHEDULE section.

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

Gas injection wells that are not declared via this keyword have their solvent fractions set to zero.

See also the GCONINJE keyword to define a group’s injection targets and constraints, and the WCONINJE keyword to define an injection well’s targets and constraints. All the aforementioned keywords are described in the SCHEDULE section.

Records: One or more records, each terminated by /
Items per record: 2

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 of a gas injection well for which the solvent fraction data is 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	`SOLVENT_FRACTION`		UDA	1
4	`SOLFRA`	A real positive value greater than or equal to zero and less than or equal to one that defines the fraction of solvent in the gas well’s injection stream. This value may be specified using a User Defined Argument (UDA).			fraction	fraction	fraction	None

Example

The following example defines the solvent fractions for three gas injection wells for when the solvent option has been activated by the SOLVENT keyword in the RUNSPEC section.
--
-- DEFINE GAS INJECTION WELL SOLVENT FRACTION
--
-- WELL SOLVENT
-- NAME FRACTION
-- --------
WSOLVENT
GI01 0.0000 /
GI02 0.5000 /
GI03 0.5000 /
/
The solvent fraction for the GI01 gas injector is set to zero and both GI02 and GI03 gas injectors have solvent fraction values of 0.5 for their injection streams.
