Batch LAS Units tab

  

This tab converts metric-imperial units for sonic and density logs, and decimal-percent for porosity logs.  For the porosity curve decimal-to-percent correction, Petra uses the units listed in LAS file header’s curve information.  

Porosity Units Conversion

Percentages can be expressed on a 0-1 scale or on a 0-100 scale, which can make calculations more difficult.  This option converts curves with PU, %, V/V, PCNT, PERC, or VOL. By default, the Do Not Convert Porosity Option is selected, which does not make any changes.  The Convert Porosity to Percent (0-100) multiplies the curve by 100; the Convert Porosity to Decimal (0-1) divides the curve by 100.

Density Log Units Conversion

This option converts density units between imperial and metric units.  By default, the Do Not Convert Density Logs Option is selected, which does not make any changes.  The Convert KG/M3 to gm/ccconverts metric density curves to use imperial units.  The convert gm/cc to KG/M3 converts imperial density curves to use metric units.
