Electro Seismic (EKS) Video #1 Question Asked
1. Main question that I am asked; can the Electro-Seismic (EKS) technique tell Gallons-Per-Minute and Depth, as they advertise;
"NO"
Public Service Announcement (PSA)

Read a copy of the Electro Seismic contract carefully, note stated limitations.
- Will not recommend drilling if 6 gpm or less.
- Cannot get a reading if salt is in the water - no reading.
- Probes must go into ground 3 feet for a normal reading, nothing less.
- Reduced accuracy if unacceptable surface conditions. Still a fee.
- Will not work if you have large fractures.
- Will not work if you have a lot of water.
- Less accurate if seismic velocities of your rock is not known.
- Seismic velocities can VARY widely for known rock types.
- Depths estimations are limited in soft soils, unconsolidated conditions. That is exactly what a fractured zone is.
- A calibration sounding is worthless due to #8 above.
