 •       UPSCLR – A GasPal Computing Grid From a Petrel File

•        Read GIIP, pore volume, horizontal permeability values directly from

      a Petrel model file — up-scale to a grid for GasPal – which reads

       grid file and sets up computations.

•        Have UPSCLR use Bg factor, net to gross, Sw and Petrel cell coordinates

     to calculate GIIP and pore volume — a check on Petrel values.

–      Create report on differences in pore volume or GIIP.

•        Add pseudo wells to generate a finer grid for more detailed simulation

     and possible infill drilling.

•        Graphically view reservoir attributes including Sw, φ, and Kh.

•        Customize color, text, zoom level, etc in reported reservoir graphs.

•        Switch view through formation layers to see difference in values

     as depth changes.
