Rock Physics relational models between seismic data and reservoir properties from Kerisi, North, and South Belut Fields in Block B, Natuna Sea are described. Specific examples from these fields are used as controls for reservoir property prediction from seismic attributes. We identify the optimum rock physics parameters, create templates for reservoir property prediction, and analyze the limitations of these models as applied to seismic data. Optimum fluid and lithology discrimination was observed to occur in LambdaRho (incompressibility) and LambdaOverMu elastic rock properties. Key controls on the robustness of the methods include depth of burial (compaction), shale volume, fluid content, cementation, sorting, seismic resolution and data quality. With the exception of the laminated Udang and Gabus reservoirs at North Belut Field, application of these methods have provided valuable inputs for well planning, static and dynamic models, hence field volumetric and reservoir performance analysis.
