Abstract

Data from 50 sonobuoys were recorded over the Lord Howe Rise Capel and Faust Basins, during a 2006 seismic survey for Geoscience Australia's Big New Oil programme. These data were interpreted and forward modelled by ray-tracing to provide an estimate of P-wave velocities in the upper sedimentary section, and hence constrain estimates of sediment thickness. Also recorded were gravity and magnetic anomaly data. These, in conjunction with the seismic reflection data, provided additional constraints upon the velocity models. Typical ranges in four model layers were: 2-2.2, 2.3-2.6, 3-3.7, 4-4.7 km/s. The top of a 5th lowermost layer was modelled in the range 5.0-5.5 km/s, and in one instance 6.5 km/s.
