Abstract
An electromagnetic (EM) survey system for determining the presence of liquid or gaseous deposits within the earth's interior. The system includes an EM pulse generator for generating the EM pulses, a data acquisition system for receiving and processing reflected signals from the earth's interior caused by the EM pulses, and a data processing system for analyzing the reflected signals to determine the presence of fluids in the earth's interior. Delivery of the EM pulses to the earth's interior can be accomplished either invasively or non-invasively. In an invasive manner, the EM pulse is delivered to the earth's interior via a set of electrodes buried shallow into the ground. In a non-invasive coupling, the EM pulse is delivered to the earth's interior via a wire loop. The reflected signals are received from the earth's interior via one of a wire loop, set of electrodes, wire antenna, or rod antenna array.
