SE sounding techniques detect electrical signals generated by the passage of seismic compression waves through water-, and hydrocarbon-bearing rocks and soils. The wave front creates a subtle electrical field when passing through the target zone and this field is measured at the surface with electrodes. SE signals are then analyzed with specialized hardware and software to produce a sounding curve. Effective depths for this method range from 10 feet to 6,000 feet. SE is a powerful method to help prevent dry holes and maximize your return on drilling investment. As illustrated below, this method is often integrated with seismic reflection and/or electrical resistivity tomography to allow for more robust interpretations.
We utilize SE for the following applications:
