seismoelectric method > Survey example

The example shows an experiment designed to overcome the low signal-to-noise ratio (SNR) associated with seismoelectric conversions. The use of limited energy sources such as a weight drop or a sledgehammer hitting a plate usually produces weak signals and requires a large amount of stacking to achieve an acceptable SNR, even at shallow depths of several meters. In this experiment, resorting to a hydraulic vibrator helped overcome this difficulty.

This work was a joint effort between WesternGeco, Schlumberger Water Services and the Curtin University; it was presented at the SEG 2012 annual meeting.
