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 for adaptively determining one or more faults from geological survey data includes: (a) generating at least one attribute volume comprising a plurality of attributes from said geological survey data; (b) identifying at least one region of interest on a predetermined cross-section of said at least one attribute volume; (c) adding at least one seed to said at least one region of interest; (d) defining at least one representative area in accordance with said region of interest; (e) starting an initial generation of at least one basic geological object by adapting said at least one seed and/or representative area; (f) selectively determining growth confidence levels for any of said at least one basic geological object based on a realistic geological principles, and mapping said at least one basic geological object with colour-coded data of said growth confidence levels; (g) monitoring a visual representation of said at least one basic geological object during said initial generation; (h) selectively stop

Abstract: Disclosed is a method of 3D object delineation from 3D seismic data comprising the steps of providing 3D seismic data (144,200,300; processing the data (210,310) based on at least one characteristic (320) whereby said characteristic is extracted from the data and compared with at least one reference characteristic and delineated (330) based on the comparison, and defining a geological element (340) based on the delineation. The characteristics (320) may be adjusted. Data can be processed (210,310) based on one characteristic (222,232) then processed based on a second characteristic (224,234) or data is processed based on two characteristics substantially simultaneously (252). Data may be processed n times (246) producing n delineations from which the geological element is defined (260).
