NAME

       exp_variogram - compute variogram for a cornerpoint grid with properties.

SYNOPSIS

       exp_variogram gridfilename=cornerpointgrid.grdecl [option=value]

DESCRIPTION

       This  program computes data for an experimental variogram from a cornerpoint geometry with
       properties. This works by choosing pairs of volumes chosen randomly, and  comparing  their
       distance  with the difference in their properties (poro or perm). Direction for pairing is
       set from the command line.

OPTIONS

       ilen Length in i-direction of subsample, specified in number of  cells.  Defaults  to  all
       cells in i-direction.
       jlen  Length  in  j-direction  of subsample, specified in number of cells. Defaults to all
       cells in j-direction.
       zlen Length in z-direction of subsample, specified in the grids length unit (typically  cm
       or m). Defaults to full height.
       imin  Can be used to limit the search area for random subsamples. Defaults to minimum i in
       inputgrid (full model).
       imax Can be used to limit the search area for random subsamples. Defaults to maximum i  in
       inputgrid (full model).
       jmin Analog to imin, but in j-direction. Defaults to minimum j in inputgrid (full model).
       jmax Analog to imax, but in j-direction. Defaults to maximum j in inputgrid (full model).
       zmin  Analog  to imin, but in z-direction and specified in the grids length unit. Defaults
       to minimum in inputgrid.
       zmax Analog to imax, but in z-direction and specified in the grids length  unit.  Defaults
       to maximum in inputgrid.
       pairs Number of pairs. Defaults to 100.
