A method for visually enhancing at least one geological feature in 3D seismic survey data, comprises the steps of: (a) selecting at least one first seismic trace from a 3D seismic survey data set; (b) subdividing said at least one first seismic trace into a plurality of identified characteristic segments; (c) generating at least one first analytical model function for each of said plurality of identified characteristic segments, utilizing at least one adapted wavelet from an existing dictionary (atom); (d) determining a matching characteristic between said at least one first seismic trace and said at least one first analytical model function; (e) optimising said at least one first analytical model function with respect to said matching characteristic; (f) repeating steps (d) and (e) until a predetermined condition is met, and (g) generating a model dataset from said optimised at least one first analytical model function for at least part of said at least one first seismic trace for visual representation. |
