2010-2011 OPERATIOnS COnTInUEd fOR THE fInAnCIAL YEAR EndEd 30 jUnE 2011 Pre-salt structure  now better imaged Sub-salt imaging  greatly improved Results are very encouraging on the new seismic datasets. Interpretation has confirmed the main post-salt amplitude supported prospects defined on earlier 3D data and further validates these prospects, providing better definition and understanding  of their potential.  Figure 1. Comparison of seismic quality showing the ‘old’ pre-existing 3D in the area with the new 3D data after it has  been exposed using the technology outlined above. Early ‘Legacy’ Data New Data Pre-stack time mitigation  converted to depth Multi-Azimuth 3D (MAZ) using reverse time mitigation (RTM) Karoon Gas Australia Ltd  Annual Report 2011 8 Shallow salt bodies with steep flanks are commonly  problematic to image properly, often requiring  different acquisition as well as processing techniques  which industry has developed over time. By acquiring wide-azimuth data in the opposite  direction to legacy data and combining the datasets,  using state-of-the-art processing techniques has  yielded much better results. Salt edges, flanks and  below salt are now apparent which has illuminated  new sub-salt and pre-salt plays (e.g. around Morro da Igreja salt structure). ? ? ? ? ?
