Reservoir Simulation of CO2 Storage using Compositional Flow Model for geological formations in Frio Field and Precaspian Basin

Abstract

CO2 storage is a greenhouse gas mitigation instrument for many countries.In this paper, we investigate the possibility of CO2 storage in the region of the Precaspian basin using the compositional flow model that was verified by the data of the Frio pilot project, USA. We use local grid refinement in the commercial reservoir simulator. In the reservoir simulation for data of the Frio Pilot project, we have achieved a good history matching of the well pressure. The different scenarios were tested and post-injection migration was shown for both case studies. The long-term reservoir simulation shows the potential amount of trapped CO2 by residual and dissolved trapping mechanisms in the Precaspian basin.

Accelerating Carbon Capture and Storage Modeling using Fourier Neural Operators

“…One approach for reducing the computational costs of numerical simulations is to use non-uniform grids to capture different responses at different grid resolutions. A popular method, known as local grid refinement 11 (LGR), has enabled scaling simulations to real-world three-dimensional (3D) carbon dioxide storage projects, where the fine-grid responses capture the plume migration while the coarser grid responses capture the farfield pressure buildup [12][13][14] . However, even with nonuniform grid approaches, these numerical models are still too expensive for tasks that require repetitive forward simulations, e.g., site selection 15 , inversion 16 , or optimization 17,18 .…”
