Abstract:
A method of performing a wellbore operation may include circulating an oil-based wellbore fluid having a conductive material therein within a wellbore, the oil-based wellbore fluid having a conductivity of at most 0.02 S/m when measured at 20 kHz; and forming a filtercake having a conductivity at least two orders of magnitude higher than the oil-based wellbore fluid on at least a portion of a wall of the wellbore.
