Controlled Imaging Of Fluid Flow And A Saline Tracer Using Time Lapse Gpr And Electrical Resistivity Tomography

A controlled imaging facility was used to setup and execute a number of lD, 2D and 3D<br>time lapse experiments in which geophysical and direct measurements were used to<br>image fluid flow and a saline tracer. The resulting data definitely proves that geophysical<br>data can map 4D fluid flow, however it is imperative to have extremely high spatial and<br>temporal sampling in order to be able to see the processes.
