Reflection coefficient measurement for water-based mud resistivity imaging
A galvanic resistivity tool with one or more measurement electrodes and guard electrodes, and one or more shielding electrodes. The impedance seen by the measurement electrode (indicative of the formation resistivity) is determined by using a directional coupler that measures a reflection coefficien...

| Zusammenfassung: | A galvanic resistivity tool with one or more measurement electrodes and guard electrodes, and one or more shielding electrodes. The impedance seen by the measurement electrode (indicative of the formation resistivity) is determined by using a directional coupler that measures a reflection coefficient of an electrical signal. |
