Abstract

The Timor Sea airborne laser fluorosensor (ALF) MkII survey was flown in 1994 by BP over the western Bonaparte Basin (Vulcan Sub-basin and Nancar Trough). 65 lines were acquired at 5,000m spacing in a NW-SE orientation. A total of 436,972 spectra were collected at an average spacing of 14.9m to 20.3m. Each recorded spectrum is the average of ten detected spectra. The strongest fluors found on the Timor Sea MkII ALF survey were located over the Jabiru Field. The anomalous intensity and distribution of these fluors suggests they are related to the field development rather than natural oil seepage. Apart from the Jabiru anomaly, the fluorescence response was very weak over the rest of the survey area. The 5km line spacing is not sufficiently close to detect most fluor clusters. The line spacing of 300m used on the nearby MkIII ALF survey over the Skua field was only just sufficient to detect the fluor cluster lying near that accumulation. The Timor Sea ALF MkII data is probably not suitable for identifying the isolated, low intensity fluors usually detectable on ALF MkII surveys in the region.
