... Abstract The uncertainties of fluvial reservoir geologic model are notably high due to complicated geological conditions and unknown strong heterogeneity. However, previous uncertainty analysis approaches mainly focus on qualitative evaluation. In this work, we proposed a novel workflow...

... conductivity contrasts, this is a challenging and novel application of CO2 EOR. The objective of this study is to obtain a reliable predictive reservoir model by integrating multi-decadal production data at different temporal resolutions into the available geologic model. This will be useful...

... to obtain coarse dynamic simulation models from high resolution static geologic models. The objective of upscaling is to preserve the maximum amount of heterogeneity with the minimum possible cost of simulation. However, the existing flow based upscaling methods rely on Steady State (SS) concepts of flow...

... Abstract A model selection process based on multi-objective optimization using a fast proxy is presented that chooses geologic models conditioned to observed flow and geomechanical responses. The responses of geologic models to injection of large volumes of CO 2 are evaluated using a proxy...

... Abstract A textbook description of history matching could indicate that it is a process wherein changes are made to an initial geologic model of a reservoir, so that the predicted reservoir performance matches with the known production history. A practitioner recognizes that this is an overly...

Figure 2 shows the reservoir model, including the macroscopic geologic model (a), the physical properties of both the reservoir and the crude oil (b) and the basic structure...

... Abstract Reconciling high-resolution geologic models with pressure and multiphase production history is one of the most time-consuming aspects of the workflow for geoscientists and engineers. Although significant advancements have been made in this area over the last decade, current industry...
