Special Issue Information

Dear Colleagues,

Prediction of subsurface flow and transport is essential in many energy and environmental applications such as enhanced hydrocarbon recovery, CO2 geo-sequestration, groundwater flow, and contaminant transport. Given the intrinsic spatial heterogeneity of the subsurface environment and the nonlinearity of governing equations of fluid flow, the prediction of subsurface flow using high-fidelity computational fluid dynamics techniques becomes challenging in terms of computational complexity and cost. Data-driven and machine learning tools can potentially tackle these challenges by offering computationally efficient alternatives to physics-based models. 

This Special Issue aims to bring together papers demonstrating the advancement of machine learning-based proxy models with the focus on forward and inverse problems related to subsurface flow and transport. We highly encourage studies on scientific machine learning frameworks such as physics-constrained deep learning algorithms, which incorporate scientific computing and data-driven models in subsurface flow problems.

Abstract
Carbon capture and storage (CCS) is an essential technology for achieving carbon neutrality. Depositional environments with sandstone and interbedded shale layers are promising for CO2 storage because they can retain CO2 beneath continuous and discontinuous shale layers.

Carbon capture and storage (CCS) is an essential technology for achieving carbon neutrality. Depositional environments with sandstone and interbedded shale layers are promising for CO2 storage because they can retain CO2 beneath continuous and discontinuous shale layers. However, conventional numerical simulation of shale–sandstone systems is computationally challenging due to the large contrast in properties between the shale and sandstone layers and significant impact of thin shale layers on CO2 migration. Extending recent advancements in Fourier neural operators (FNOs), we propose a new deep learning architecture, the RU-FNO, to predict CO2 migration in complex shale–sandstone reservoirs under various reservoir conditions, injection designs, and rock properties. The gas saturation plume and pressure buildup predictions of the RU-FNO model are 8000-times faster than traditional numerical models and exhibit remarkable accuracy. We utilize the model’s fast prediction to investigate the impact of shale layer characteristics on plume migration and pressure buildup. These case studies show that shale–sandstone reservoirs with moderate heterogeneity and spatial continuity can minimize the plume footprint and maximize storage efficiency. Full article
