Enhanced Visualisation of Geologic Features in 3D Seismic Survey Data

摘要

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.

1. A method of visually enhancing at least one geologic feature in 3D seismic survey data, comprising the steps of:
(a) loading 3D seismic survey data into a computer system for processing and visual representation; (b) generating at least one attribute volume defining a first plurality of voxels in Cartesian space and comprising at least one attribute derivable from said 3D seismic survey data; (c) generating a first Radon data volume, defining a second plurality of voxels, from data resulting from a transaxial Radon Transform of said at least one attribute volume with respect to a first Cartesian axis; characterised in that the method further comprises the steps of: (d) generating a second Radon data volume, defining a third plurality of voxels, from data resulting from a transaxial Radon Transform of said first Radon data volume with respect to a second Cartesian axis; (e) generating a third Radon data volume, defining a fourth plurality of voxels, from data resulting from exponentiating a characteristic parameter of each one of said third plurality of voxels forming said second Radon data volume to a predetermined first power value, (f) 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 generating a final enhanced attribute data volume; and (g) displaying said final enhanced attribute data volume on a display device of said computer system.
