Abstract

The Bonaparte Basin airborne laser fluorosensor (ALF) MkII survey was flown in 1989 by BP over the northern Petrel Sub-basin, Darwin Shelf and Malita Graben. The survey was designed to detect natural oil seepage over a region of the Bonaparte Basin, Australia, in an effort to refine the petroleum prospectivity assessment. The survey was acquired in two separate parts. The larger southwest part extends up to 230km east to west and up to 240km north to south. The northwest part extends about 120km east to west and an average of 100km north to south. A total of 872,412 fluorosensor spectra were recorded. This report presents a re-interpretation of the BP data by Signalworks Pty Ltd using the ALF Explorer software. A total of 1,689 fluors were picked out of the 872,412 recorded spectra in the final interpretation. This is an average fluor density of 1.94 fluors per thousand spectra. The fluorescence response over most of the survey area consisted mainly of relatively low confidence fluors (compared to the more reliable MkIII ALF survey data). Some of the regions of increased fluor density correspond to regions having generally higher F/R values, probably caused by changing water properties. These areas may not necessarily have increased levels of hydrocarbon leakage.
