Electrical Resistivity Imaging  (ERI) is a proven application for locating aquifers and optimising production bore locations. Its precedents Resistivity sounding and profiling have been used for nearly 50 years. Resistivity Imaging brings all of the strengths of sounding and profiling together and creates an electric image that's much easier to interpret. Its nominal application band is from the surface to about 200 metres. It can show aquifer thickness, formation yield, give an idea of water quality or contamination, concealed structure, faulting and weathering in a  wide variety of conditions.

Concealed river channel,

ERI to locate high yielding gravels for ground water.

High Resistivity Gravels in an old concealed river channel that was confirmed by drilling, (Project work in SE Asia)

1. The red and brown sections of the image are the higher yielding gravels. The base is at about 26 to 28m.

2. The green and yellow sections are lower yielding silts and fine sands
