Logging while drilling (LWD) resistivity imaging has been applied in water-based mud systems since the early 1990s. These resistivity images are recorded by a rotating electrode (or electrodes) mounted just behind the downhole drilling assembly. The evolution of the current generation of high-Previous HitresolutionNext Hit LWD resistivity imaging tools, deployed during the last decade, has seen a progressive increase in the along-hole Previous HitresolutionNext Hit, with today’s highest Previous HitresolutionTop tools achieving nominal along-hole resolutions of approximately 0.5 in. with full 360° azimuthal borehole wall coverage.
