3D surveys

Field system While 2D surveys still make up the majority of surveys there is an increase in 3D surveys where electrodes are placed in 3D grids along the surface and possibly in boreholes. While collecting and processing such surveys is substantially more involved than 2D surveys, 3D surveys provide substantial value as they can allow for better resolution of subsurface electrical property distributions than 2D surveys.
