Abstract
A seismic communication system suitable to communicate information to an underground device is disclosed. A seismic source (preferably on or near the surface of the earth) generates a timed series of seismic shots. These shots are then detected by one or more seismic receivers underground. Depending on the timing of these seismic shots, and the communication protocol selected, various information may be communicated to the underground target. Such a system is particularly desirable when the underground device includes a perforating gun because the perforating gun may not only be remotely detonated without the drawbacks of previous methods, but the detonation of the perforating gun charges may also be detected, giving an indication whether substantially fewer than all of the explosive charges detonated.
