A method of locating potential oil and gas deposits by directing a beam of coherent high-intensity infrared radiation into the atmosphere above and adjacent the earth's surface, the wave length of the beam being selected such that it energizes selected hydrocarbon gas molecules, the beam being scanned in a raster pattern, detecting re-radiation generated by hydrocarbon molecules in the atmosphere which are energized by the infrared radiation, converting the detected re-radiated energy into electrical signals, and displaying on a raster scanned imaging tube a pictorial representation employing the electrical signals to indicate the presence of hydrocarbon molecules as an indication of the possibility of deposits of oil and gas in the earth below.
