Method and apparatus for transmitting electromagnetic waves and analyzing returns to locate underground fluid deposits

A method for determining the presence of fluids within the earth's interior, comprising:

• generating a series of electromagnetic pulses into the earth's interior, said generating comprises:
• storing a voltage in an energy storage device;
• and generating said series of electromagnetic pulses when said voltage in said energy storage device reaches a predetermined threshold;
• receiving a series of reflected signals from the earth's interior, said reflected signals being said electromagnetic pulses reflected from the earth's interior;
• passing said series of reflected signals through a filtering and amplification channel;
• converting said amplified reflected signals to digital signals;
• and
• comparing said reflected signals to determine the presence of a fluid within the earth's interior.

An apparatus, comprising:

• means for generating a plurality of electromagnetic pulses, said generating means comprises:
• an energy storage device for storing a voltage supplied from an external source;
• a sparkgap switch, coupled to said energy storage device, for generating said electromagnetic pulses when a predetermined threshold voltage of said energy storage device is achieved;
• and
• a matching network, coupled to said sparkgap switch, for passing said electromagnetic pulses to said transmit ground coupling device;
• means for delivering electromagnetic pulses generated by said pulse generating means to the earth's interior;
• means for processing a plurality of reflected signals, said reflected signals being electromagnetic pulses delivered by said delivering means and reflected from the earth's interior;
• means for receiving and supplying reflected signals to said processing means;
• and
• means for comparing received reflected signals to determine the presence of fluids in the earth's interior.
