Computers in Geology (GC-03)
One of the most interesting uses of computers in geologic work deals with seismic exploration for oil. Small manmade earthquakes are produced by compressed air, a small explosion in a drill hole, or by a special vibrating truck. Echoes, or reflections of energy, from underground layers of rock are detected and recorded on magnetic tape. These data can then be transmitted via satellite to a data-processing center in Denver, Houston, or New York. Computations of times required for thousands of these echoes to occur are interpreted by a computer to locate areas where deep rock structures may contain oil or gas.
