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.

Data-driven, interpreter guided visual enhancement of geologic features in 3D seismic survey data

A method of visually enhancing at least one geologic feature in 3D seismic survey data, comprising the steps of: (a) generating at least one attribute volume definable in Cartesian space and comprising at least one attribute derivable from said 3D seismic survey data; (b) generating a first Radon data volume from data resulting from a transaxial Radon Transform of said at least one attribute volume with respect to a first Cartesian axis; (c) generating a second Radon data volume from data resulting from a transaxial Radon Transform of said first Radon data volume with respect to a second Cartesian axis; (d) generating a third Radon data volume from data resulting from exponentiating a characteristic parameter of each one of a plurality of voxels forming said second Radon data volume to a predetermined first power value, and (e) applying a first Inverse Radon Transform to said third Radon data volume with respect to said second Cartesian axis, and a subsequent second Inverse Radon Transform to the resulting data from said first Inverse Radon Transform with respect to said first Cartesian axis.
