`PORV`

Recognised by the OPM Flow parserEDIT

PORV defines the pore volumes for all the cells in the model via an array. The keyword can be used for all grid types, except for the Radial Grid geometry. The keyword effectively overwrites previously entered and calculated data. The area to be modified can be defined via the various grid selection keywords, ADD, BOX, EQUALS, etc., and areas that are not selected remain unchanged.

Notes:

The number of entries should correspond to the NX x NY x NZ parameters on the DIMENS keyword in the RUNSPEC section, unless the BOX keyword defines a sub area of the grid, in which case the total number of entries should correspond to the number of cells defined by the BOX statement.

Values not reset by this keyword remain unaltered.

The keyword is terminated by a “/”.

Records: An array of values covering the grid

Parameters

No.	Name	Description	Field	Metric	Lab	Default
1	`PORV`	PORV is an array of real positive numbers assigning a pore volume to each cell in the model. Only the values in the currently defined input BOX needed be entered. Repeat counts may be used, for example 20*100.0.	rb	rm3	rcc	None

Example

--
-- DEFINE INPUT BOX FOR EDITING INPUT ARRAYS
--
-- ---------- BOX ---------
-- I1 I2 J1 J2 K1 K2
BOX
1* 100 1* 100 20 20 / DEFINE BOX AREA
--
-- SET PORV FOR THE GRID BLOCKS
--
PORV

--
-- DEFINE END OF INPUT BOX EDITING OF INPUT ARRAYS
--
ENDBOX
Here the BOX statement is used to define the input grid for the PORV keyword, which overwrites the pore volume previously calculated with pore volume values of zero, resulting in a no-flow boundary in that part of the field between layers 19 and 21, since layer 20 is deactivated. The ENDBOX keyword resets the input box to the full grid.
