We will present fluid substitution well log modeling results based on Gassmann's equation and application of conventional AVO and other techniques such as Elastic Impedance and Simultaneous Inversion followed by lambda-rho mu-rho (LMR) techniques in a pilot area of interest. The results of the pilot study were validated with the known well fluid status in the pilot area. Mapping of the different water-oil-gas fluid response using the LMR technique shows a reasonably good agreement with currently known well saturations. It is, however, difficult to discriminate reservoir sub-layer water-cut percentages due to data resolution limitations. Generally, the results of the analysis indicate potential to identify hydrocarbon to water fluid contents, with the above constraints.
