Reservoir characterization from seismic waveform using forward modeling and pattern recognition

Suppose we are given several wells in a seismic survey area. Each has a lithological column (or facies log), and sonic and density logs. The lithological section defines a geologic section type—a specific set of target layers with defined thickness, lithology, porosity, presence of hydrocarbons, and so on. The problem is now to predict the geology away from these wells.
