A 12-million cell (150m ϫ 150m ϫ 1m), 3D geocellular model covering the Boscán field has been constructed. This presentation describes the results of this full-field reservoir model construction that has integrated core, well, seismic, pressure, and performance data.In 2007, new 3D seismic was acquired over the south area of the field. The seismic was reprocessed with pre-existing 3D to enhance mapping of structural and stratigraphic features and provide better spatial control, improving on previous interpretations made with only well data and 2D seismic lines.The re-processed 3D was used to re-evaluate horizon and fault mapping over the field. Using coherence-based methods, a study of regional tectonics for the area, and well correlation and performance data, we imaged a structural volume and different fault patterns originating from the main field-bounding Boscán fault. Though many of the faults do not have significant vertical offset, they appear to have pronounced effect on fluid movement and compartmentalization.Electrofacies modeling tying core to logs was used to define trends and spatial probability of reservoir and rock properties across the field. In addition, seismic attribute data was qualitatively used to help guide reservoir variability between wells and define potential depositional features within a tidally-influenced fluvial-deltaic system.Multi-point statistics (MPS) was applied to allow use of field-scale regional trends and shapes that mimic depositional features to ensure that spatial probability derived from seismic and well data could be honored. Multiple scenarios have been generated that capture the uncertainties in reservoir connectivity and associated distribution of rock quality parameters across the model area. Cells were populated with two-component lithofacies, volume of shale (VSH), effective porosity (PHIE), effective water saturation (SWE), and permeability (PERM) using a Petrophysical model developed from an extensive database of 1000ϩ wells.The full field 3D geocellular model has been downscaled to several workable smaller sector models to help address specific past performance and future dynamic behavior. Production history matching and numerical fluid flow simulation is currently underway. The focus of the history matches, in part, is to shed light on fault compartmentalization, reservoir connectivity and quality distribution, and fluid movement associated with an encroaching aquifer and water injection for pressure maintenance through time.
