Abstract
A method for reducing noise and for deriving new data from seismic and seismic derived rock property data includes determining a rate of change and direction of rate of change of amplitudes of seismic and seismic derived rock property cubes along microlayer horizons and filtering this data long the microlayer horizons. To facilitate this determination, microlayer horizons can be locally rotated around each microlayer horizon definition point. The data determined for the microlayer horizons are sequentially organized in time whereupon a display of the microlayer horizons can be sequentially stepped through to view the output data of each microlayer horizon.
