Abstract: A method for enhancing visual representation of a geologic feature in 3D seismic survey data, comprising the steps of: (a) generating a plurality of first attribute volumes, each comprising at least one characterising attribute, derivable from said 3D seismic data and different from the characterising attributes of any one of the other said plurality of first attribute volumes; (b) generating a plurality of filtered attribute volumes for each one of said plurality of first attribute volumes, utilizing a plurality of distinct filter settings at each one of said at least one characterising attribute; (c) generating a composite attribute volume by selectively combining one or more of said plurality of filtered attribute volumes so as to maximise visual detectability of said geologic feature.

Abstract: A method is provided for an improved interpretation of seismic data, comprising the steps of: (a) obtaining a 3D seismic data set from a predetermined region; (b) generating at least one attribute volume comprising at least one attribute of said 3D seismic data; (c) selecting a zone of interest from said at least one attribute volume of said 3D seismic data set; (d) determining a frequency spectrum of said zone of interest; (e) generating a synthetic model of said zone of interest based on said frequency spectrum of said zone of interest and the model defined by at least a three dimensional space, wherein a first variable parameter is variable in a first dimension of the space, and at least a second variable parameter is variable in at least a second and/or third dimension; (f) calibrating said synthetic model utilising additional data indicative to physical properties of said zone of interest; (g) utilising said calibrated synthetic model to provide the frequency spectrum of a synthetic seismic response of s
