Dual Lateral Logging Tool
Using an array of electrodes to focus the measuring current into the formation, the Dual Laterolog provides both Deep and Shallow formation resistivity measurements in conductive borehole environments. An SP reading is also recorded by the instrument.
The measurement is particularly suitable for high resistivity formations. Both deep and shallow readings allow for visual identification of permeable formations.
Features
- Combinable with other Gallop tools
- Can distinguish formations bearing conductive fluids (including salt water and mud filtrate) from formations with non-conductive fluids (oil and gas)
- Spontaneous Potential (SP) reading included
Applications
- Invasion Profile determination
- Water Saturation measurement
- Identification of fluid contacts
