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. WebThe dual induction focused log measures the invasion zone resistivity and also the flushed zone resistivity. Induction logging should be used in non-salt-saturated drilling mud to obtain a more accurate value of true …
