Optimizing the reservoir model of delta front sandstone using Seismic to Simulation workflow- A case study in the South China Sea

Offshore development requires detailed understanding of subsurface reservoirs and proper well placement. Use of all available information in an integrated reservoir model leads to improved production rates and higher EUR. Conventional methods use well logs, geologic information, and structure from seismic interpretation in static reservoir models, which, in turn, predict future production and evaluate alternative management scenarios. However, these models, which use different data types in isolation, often fail replicate past production (history matching). An integrated seismic-to-simulation workflow is presented in this paper; dense 3D seismic data provide a great deal of lateral lithofacies and rock-property information that is essential to the static model.
