This paper describes a process by which seismic related properties from 2D seismic lines are extracted and a 3D property model is constructed. This interpretation workflow is then tested and described on a pilot area in the northern portion of the onshore Gippsland Basin, Australia. The primary reservoir sands in this region appear to be deposited in a channel recognised on 2D seismic lines. Seismic inversion was performed on each 2D seismic line to differentiate between geological bodies, and these inverted seismic sections were fed into a 3D model in an attempt to track the sand filled channels and seals, based on the seismic-derived attributes. The sealing sequence is characterised by distinctive log/seismic properties, which were modelled in 3D, and attempts are made to discuss seal potential in terms of geometry and integrity.
Key words: Gippsland, property modelling, seal, sequestration.
