Bentu, Seng and Segat are three adjacent gas fields in the Central Sumatra Basin. Development of these fields required an integrated reservoir model to incorporate all available data, in order to minimise the impact of the limited quantity and quality of data. The model team included Geologists, Geophysicists, and Reservoir Engineers (GGR). The team’s workflow was customised to incorporate the available data set: 2D seismic lines from various vintages and no raw data, relatively few wells given the closure size, all wells located along the anticline axis, and only one conventional core. To build the best model from the limited data, it was important to understand the depositional facies, rock properties, seismic character and to fully use all existing data. The model integrated the depositional facies study, petrophysical analysis and multi 2D seismic inversion. This method can be applied other fields with limited data to support field development scenario screening. Keywords: Integrated Reservoir Study, GGR Model.
