Petrosys mapping and interpretation software were utilised for the entire project. Sherbrook horizon TWTs were derived from open file industry TWT contour interpretations and seismic correlations. The resulting TWT contour grid was convolved with a TWT depth relationship derived from well tops, with logical constraints outside data zones, to create the depth grid. Eumeralla, Crayfish and Basement TWT horizons were derived from correlated and contoured seismic TWTs. The resulting TWT contour grids were convolved with TWT depth relationships derived from well tops, with logical constraints outside data zones, to create the depth grids. Onshore Otway Basin produced by Bruce Finlayson 1993. Offshore Otway Basin and tie to onshore produced by Brent Jensen-Schmidt, 1995. Both were consulting geophysicists for the Energy Resources Division, DMITRE. Update to data by David Rowe and Witold Severyn 1997-99. Final compilation by Brent Jensen-Schmidt 2001. Final files produced by Energy Resources Division, DMITRE. Positional accuracy:This is dependant on the grid mesh size, in these cases 200*200 metres. Attribute accuracy:Within 2 metres of interpreted well tops Logical consistency:Highly consistent Completeness:Complete |
