f Lateral prediction of reservoir properties using seismic attributes with well log data

Seismic attributes are mathematical transformations of seismic data, typically dove after stacking and imaging (Taner et al, 1979) . Examples are amplitude, instantaneous frequency, P and S velocities, band-limited impedance, apparent dip or azimuth, and others . Rock or petrophysical propertjes (e .g ., porosity, Poisson's ratio, relative shale volume, fluid content, and others) describe the medium itself, and are measured or computed in situ from logs. Seismic attributes carry the promise of indicating such real propertjes, since in some circumstances certain attributes can be expected to correlate highly with specific rock properties (Sonneland et al, 1990)
