`WMICP`

Recognised by the OPM Flow parserSCHEDULE

The WMICP keyword defines a water injection well's microbial, growth, and cementation injection stream solutions, where the rate-limiting components are suspended microbes, oxygen, and urea concentrations respectively. These concentrations are used when the MICP keyword in the RUNSPEC section has been used to activate OPM Flow’s Microbially Induced Calcite Precipitation model.

Note the keyword should only be used for wells declared as water injection wells via the WCONINJE keyword in the SCHEDULE section.

Note

This is an OPM Flow specific keyword.

Notes:

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

Water injection wells that are not declared via this keyword have their concentrations defaulted to zero.

Records: One or more records, each terminated by /
Items per record: 4

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 connection 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	`MICROBIAL_CONCENTRATION` manual: `MICRCON`	MICRCON is a real positive value that defines the microbial concentration of the well’s injection stream.	DOUBLE	Concentration	lb/stb	kg/sm3	gm/scc	0.0
3	`OXYGEN_CONCENTRATION` manual: `OXYGCON`	A real positive value that defines the oxygen concentration of the well’s injection stream.	DOUBLE	Concentration	lb/stb	kg/sm3	gm/scc	0.0
4	`UREA_CONCENTRATION` manual: `UREACON`	UREACON is a real positive value that defines the urea concentration of the well’s injection stream.	DOUBLE	Concentration	lb/stb	kg/sm3	gm/scc	0.0

Example

--
-- DEFINE WATER INJECTION WELL MICROBIAL, OXYGEN, AND UREA CONCENTRATIONS
--
-- WELL MICROBIAL OXYGEN UREA
-- NAME MICRCON OXYGCON UREACON
-- -------- -------- --------
WMICP
WI01 0.01 /
WI02 1* 0.04 /
WI03 1* 1* 60.0 /
WI04 1* 0.04 60.0 /
/
Here the microbial concentration for well WI01 is set to 0.01, the oxygen concentration for well WI02 is set to 0.04, the urea concentration for well WI03 is set to 60, and the oxygen and urea concentrations for well WI04 are set to 0.04 and 60 respectively.
