WebFlushed Zone Resistivity Log • This log is used to determine the resistivity of a region that is very close to the borehole (i.e. flushed zone). The procedure is by knowing the resistivity of the drilling fluid (the resistivity of mud filtrate,???) and making some assumption about: –Drilling fluid saturation of the flushed zone.
