The Development and Application Results of Domestic Micro Resistivity Imaging ERMI

Enhanced Resistivity Micro-Imager (ERMI) has been developed successfully by CNOOC. It has good acclimatization for all kinds of wells in complex borehole environment by special circuit and mechanical technology advantages, and can provide high quality borehole resistivity image. Equipped with powerful geological interpretation software, elaborate data processing can be finished, and various geological interpretation results can be obtained. By ERMI's testing at multiple wells, good technical function and image details are equivalent to international advanced tools. Since December 2011, ERMI has begun to work in multiple oilfields at home and abroad.
