Abstract

The Barrow/Dampier airborne laser fluorosensor (ALF) survey was flown in May 1994 using the ALF MkIII system. This system uses a 266nm laser wavelength, shorter than the 308nm used in the MkII system. The Raman peak wavelength is 293nm and the fluorescence region is 320nm to 580nm. Approximately 20,000km of data was acquired in a NW-SE direction with a line spacing of 1000m. The survey covers several oil and gas fields including Goodwyn gas and condensate field, North Rankin gas field, Cossack and Wanaea oil fields, Legendre oil field and the Wandoo heavy oil field. Several additional lines (10010 to 10140) were flown over part of the Goodwyn field and these were separated during the initial analysis. This avoided the closer line spacing affecting the fluor patterns on the regional mapping. The 14 Goodwyn lines contain 117,558 spectra. The data was re-interpreted using ALF_Explorer software, which showed that several low intensity fluor clusters could be identified on the Barrow/Dampier ALF survey. These clusters should be compared with geological interpretations to determine their cause. The wide 1km line spacing may be too wide to identify any higher intensity fluor clusters. Fluor spectra shapes are unusually consistent over this survey. This is reflected in the fluor peak wavelength map (Figure 11). The Goodwyn ALF survey with a 500m line spacing detected many more fluors than the regional survey, including many of higher intensity. The Goodwyn survey does not cover a wide enough area to show if the fluor clusters are associated with accumulations.
