Seismic reservoir characterisation of the Miocene carbonates of SE Asia faces a number of challenges: the heterogeneous nature of the carbonates at many scales, the relatively low elastic property sensitivity of carbonate rocks to fluids and the limitations of the seismic data in terms of bandwidth, angle range and signal to noise. A recent well drilled into a carbonate reef in the Nam Con Son Basin offshore Vietnam provides a useful case study to assess these challenges.
