Learning the Factors Controlling Mineralization for Geologic Carbon Sequestration

no code implementations20 Dec 2023 Aleksandra Pachalieva, Jeffrey D. Hyman, Daniel O'Malley, Hari Viswanathan, Gowri Srinivasan

We found that the dissolution reaction rate constant of quartz and the distance to the flowing backbone in the fracture network are the two most important features that control the amount of quartz left in the system.

Reconstruction of Fields from Sparse Sensing: Differentiable Sensor Placement Enhances Generalization

no code implementations14 Dec 2023 Agnese Marcato, Daniel O'Malley, Hari Viswanathan, Eric Guiltinan, Javier E. Santos

Recreating complex, high-dimensional global fields from limited data points is a grand challenge across various scientific and industrial domains.

Physics-informed machine learning with differentiable programming for heterogeneous underground reservoir pressure management

1 code implementation21 Jun 2022 Aleksandra Pachalieva, Daniel O'Malley, Dylan Robert Harp, Hari Viswanathan

To tackle this, we use differentiable programming with a full-physics model and machine learning to determine the fluid extraction rates that prevent over-pressurization at critical reservoir locations.

Multi-Scale Neural Networks for to Fluid Flow in 3D Porous Media

no code implementations10 Feb 2021 Javier Santos, Ying Yin, Honggeun Jo, Wen Pan, Qinjun Kang, Hari Viswanathan, Masa Prodanovic, Michael Pyrcz, Nicholas Lubbers

The permeability of complex porous materials can be obtained via direct flow simulation, which provides the most accurate results, but is very computationally expensive.

Modeling nanoconfinement effects using active learning

no code implementations6 May 2020 Javier E. Santos, Mohammed Mehana, Hao Wu, Masa Prodanovic, Michael J. Pyrcz, Qinjun Kang, Nicholas Lubbers, Hari Viswanathan

At this scale, the fluid properties are affected by nanoconfinement effects due to the increased fluid-solid interactions.
