Name
vol — Volume calculation
Syntax
vol [acc] [gau] [are]
Description
Volumetric calculation on grid. Result of a volume calculation is placed in @volume which can be retrieved to a Tcl varible by set vol [gvar volume].
Arguments
No argument. Calculate the volume of the active grid.
acc
Accumulate the volume into the volume variable.
gau
Calculate volumes after four corner point geometry using gaussian quadrature.
are
Calculate the area of the active grid. Result of a area calculation is put in @area which can be retrieved to a Tcl varible by set area [gvar area].
Related command object
Volume bulk calculation
Calculate bulk volume for a reservoir structure.
