isualization of subsurface fluid flow using Fluid Flow Electromagnetic method

为了可视化地下流体的动力学行为，发明了流体流动电磁法，用于观测由电动力现象引起的瞬变电磁。这种方法是基于同时观测电场和磁场的瞬态变化。本研究开发了两分量电场和三分量磁场的测量设备，以及根据观测数据估计地下流体流动方向的数据分析程序。

In order to visualize dynamic behaviors of subsurface fluid, Fluid Flow Electromagnetic method that observe transient electromagnetic due to electrokinetic phenomenon was invented. This method is based on the simultaneous observation of the transient changes of both electric and magnetic fields. In this research, measurement equipment for measuring two components of electric field and three components of magnetic field and the data analysis program for estimating the flow direction of subsurface fluid from the observed data were developed.
