Large model size and multiple predictive simulation scenarios are two of the primary challenges in reservoir modeling and simulation. In trying to capture heterogeneity within a reservoir, the cell count can increase drastically by adding horizontal and vertical resolution. In addition, multiple predictive and optimization scenarios designed to investigate strategies for drilling, optimization of production, and net present value analysis and carbon dioxide injection for enhanced oil recovery (EOR) and storage can take considerable time and computational power. These challenges slow down simulation speed and overall computation time, leading to increased project timelines, and can cause project delays. To solve these issues, an integrated model optimization workflow was proposed, as well as the design and construction of a high-performance parallel computer cluster built at the Energy & Environment Research Center (EERC). To obtain the maximum speed-up for this integrated optimization workflow, a scalability test of the cluster for multiple simulation jobs over various cores was performed. This was followed by a grid sensitivity analysis that aims to find the coarsest grid cell size that will capture the necessary heterogeneity of the reservoir. Then numerical tuning was performed with the objective of reducing processing time while minimizing material balance error and solver failure percent. Finally, a sensitivity analysis was performed to identify properties and parameters that most affect the history match or predictive simulations.
