To improve the accuracy of groundwater surveys and PS logging and density logging analyses.
"Electrical logging" is a method that involves lowering electrodes into a borehole to pass an electric current through the geological layers and continuously measure their resistivity. In addition to measuring the resistivity of the geological layers, the naturally occurring electric potential generated electrochemically within the borehole is also measured, which can be used for stratigraphic comparison and permeability assessment through logging diagrams. 【Features】 ■ Utilizing the analog display of the measured resistivity and natural potential, it is possible to determine the thickness, continuity, stratigraphic comparison, detection of aquifers, and identification of impermeable layers. *For more details, please download the PDF or feel free to contact us.

Company information
Our company has been engaged primarily in geological structure surveys and ground property investigations through elastic wave exploration, electrical exploration, and logging using boreholes, with the motto of "safe, swift, and careful observation and measurement" and "high-precision and rapid analysis using advanced systems." Additionally, we conduct investigations such as buried pipe surveys using ground-penetrating radar, depth surveys for guardrail posts, dynamic seismic performance assessments of wooden houses using the Waseda method, simultaneous measurement of microtremors inside boreholes and at the surface, as well as investigations to understand the amplification characteristics of earthquakes (transfer functions) through standalone measurements at the surface. Please feel free to contact us if you have any requests.
