High-resolution images obtained in resistive environment

High-resolution imaging has been used for some time in water-based mud (WBM), where the conductive mud environment benefits the use of resistivity imaging. In oil-based mud (OBM), however, the resistive mud properties make it difficult to gain high-resolution resistivity images. This is further complicated by the relationship between the frequency of the electrical signal and the varying response to different resistivities.
To overcome the issue of different frequency responses to various resistivities, Halliburton designed the tool to work at three frequencies simultaneously to allow a range of less than 0.2 to more than 2,000 ohmm in a single pass—an industry first.
