NAME

       cpchop_depthtrend - Upscale simple statistics

SYNOPSIS

       cpchop_depthtrend gridfilename=cornerpointgrid.grdecl [option=value]

DESCRIPTION

       This  program is a variant of cpchop. Instead of subsampling randomly, it picks subsamples
       downwards in a model. It is  specifically  designed  for  extracting  laterally  extensive
       subsamples  in  specified  intervals  downwards through a model, in order to analyze depth
       trends in porosity in particular.

       Example usage:

       cpchop_depthtrend gridfilename=cornerpointgrid.grdecl subsamples=100 ilen=5 jlen=5 zlen=5

OPTIONS

       zresolution Vertical distance between subsamples. Defaults to 1.
       subsamples Number of subsamples. Defaults to 1.
       filebase If supplied, grdecl-files for each subsample will be written to files named using
       this filebase, it may include directory names.
       resultfile Name of a textfile to output table of results per subsample to.
       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.
       upscale Boolean for whether to do upscaling on the subsamples, either true  or  false.  If
       the  objective  is  to  obtain a grdecl-file for the subsample, set to false for run time.
       Defaults to true.
       bc Boundary condition type for upscaling, either fixed or periodic. Defaults to fixed.
       resettoorigin If true, outputted grdecl-file will have its ZCORN-values and  COORDS-values
       shifted  so  that  the model is defined at the origin. If false, the outputted grdecl-file
       will be located in its original position. Defaults to true.
