Dynamic Reservoir Modeling is a 3D geocellular time lapse method used to integrate static (rock properties) and dynamic (from reservoir surveillance) reservoir data for Duri Field. This tool improves our ability to predict reservoir properties such as steam zone extent and remaining oil at any given location. The steam flood dynamic data from TOW-observation well (temperature log, steam saturation and current oil saturation) was loaded from the field database and used to populate the full-field static model Sgrid using sequential kriging and sequential Gaussian simulation collocated cokriging, geostatistical methods were used to constrain dynamic properties distribution by rock properties. For horizontal well path candidate review, selection and placement during drilling several visualizations were generated, including:• 2D-maps of Current Net Oil Pay Isochore• Average or Maximum Temperature Map• Steam Thickness Map• Steam Saturation Map• Oil Swept Ratio Map.Additionally, 2D/3D Property Cross Sections from 3D-geocellular model were generated to visualize overlying multiple static/dynamic properties. The drilled wells data were used to validate and update the reservoir model.
