✨ CPCHOP_DEPTHTREND ✨

okay bestie, so this is cpchop_depthtrend from the User Commands section of the manual, and it's literally about upscaling simple statistics 💅

🦋 NAME 🦋

cpchop_depthtrend — upscale simple statistics ✨

🎀 SYNOPSIS 🎀

cpchop_depthtrend gridfilename=cornerpointgrid.grdecl [option=value]

🌸 DESCRIPTION 🌸

so this program is a whole variant of cpchop, okay? instead of subsampling randomly, it picks subsamples downwards in a model 🫶 it's specifically designed for extracting laterally extensive subsamples in specified intervals downwards through a model, in order to analyze depth trends in porosity in particular. no cap, that's the whole point 💖

Example usage:

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

👑 OPTIONS 👑

  • zresolution — vertical distance between subsamples. defaults to 1. like, the gap between each lil slice 🌈
  • subsamples — number of subsamples. defaults to 1.
  • filebase — if supplied, grdecl-files for each subsample will be written to files named using this filebase, and 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. periodt 📍
