Dual Induction Tool
Precision Conductivity Measurement for Subsurface Analysis
The Dual Induction Tool generates an electromagnetic field around the borehole and measures the formation’s response to determine conductivity. This advanced tool is ideal for analysing subsurface formations where conductivity (the inverse of resistivity) provides critical insights into mineralogy and fluid properties.
Clay formations typically exhibit higher conductivity compared to sandy formations, making this tool particularly useful for distinguishing between different geological layers. It operates effectively in dry, fluid-filled, and PVC-lined boreholes and is best suited for high-conductivity (low-resistivity) formations with values below 200 Ohm.m.
