A resistivity [[scale]] used with [[laterolog|laterologs]] and guard logs which compresses high [[resistivity]] values. Below midscale, the scale is linear with resistivity. Above midscale, the scale is scaled in resistivity units, but is linear with [[conductivity]] (reciprocal of resistivity). The hybrid scale presentation has been replaced by the logarithmic scale on modern laterologs and guard logs. {{ :terms:glsp50f1.gif }}
