`SCVD`

Recognised by the OPM Flow parserSOLUTION

The SCVD keyword defines the initial coal solvent concentration versus depth tables for each equilibration region for when the coal phase has been activated in the run via the COAL keyword in the RUNSPEC section. The keyword may be used in conjunction with the SOLVCONC keyword in the SOLUTION section, to fully describe the initial state of the model. Note both SOLVCONC and SCVD are optional as the simulator will calculate the coal gas concentration based on the equilibrium concentration and the block pressure.

This keyword is not supported by OPM Flow but would change the results if supported so the simulation will be stopped.

Notes:

The keyword is followed by NTEQUL records as declared on the EQLDIMS keyword in the RUNSPEC section.

Each table must contain a minimum of two rows and a maximum of NDRXVD rows as declared on the EQLDIMS keyword in the RUNSPEC section.

Each table is terminated by a “/” and there is no “/” terminator for the keyword.

See also the SOLVCONC, GCVD, GASCONC and GASSATC keywords in the SOLUTION section.

Records: Fixed number of records
Variadic: The record accepts a variable number of items

Parameters

No.	Name	Description	Type	Dimension	Field	Metric	Lab	Default
1	`DATA` manual: `DEPTH`	A columnar vector of real monotonically increasing down the column values that defines the depth values for the corresponding coal solvent concentration, SCVALS.	DOUBLE	Length, 1	feet	m	cm	None
2	`SCVALS`	A columnar vector of real values that defines the coal solvent concentration values at the corresponding DEPTH.			Mscf/ft3	sm3/m3	scc/cc	None

Example

Given NTEQUL equals three and NDRXVD is greater than or equal to two on the EQLDIMS keyword in the RUNSPEC section, then the following example defines the coal solvent concentration versus depth functions.
--
-- DEPTH SOLVC
-- MSCF/FT
-- ------ --------
SCVD
100.0 75.5000
1000.0 75.5000 / SC VS DEPTH EQUIL REGN 01
-- ------ --------
100.0 65.5000
1000.0 65.5000 / SC VS DEPTH EQUIL REGN 02
-- ------ --------
100.0 60.0000
1000.0 60.0000 / SC VS DEPTH EQUIL REGN 03
Here three tables are entered with a constant coal solvent concentration versus depth relationship for each equilibration region
