In the search for oil and gas, the direct observation of hydrocarbon signatures in seismic data greatly reduces exploration risk. In the 1970s we began to realize how much important information could be interpreted from seismic amplitude, and bright spots were born. Today prestack as well as poststack amplitudes are evaluated for numerous direct hydrocarbon characteristics, such as dim spots, polarity reversals, and bright spots. As we tackle the more difficult exploration problems, the somewhat-direct detection of hydrocarbons becomes even more important.
Brown and Abriel explain how dim spots and polarity reversals occur and emphasize that we must look beyond...
