CCS/CCUS will play a critical role in reducing CO2 emissions for a variety of industries. But what is actionable today, and how do we de-risk our projects to ensure we meet our goals? Pressure transient testing in CCS projects is essential for reservoir characterization, leakage detection, storage capacity estimation, performance assessment, model calibration, and regulatory compliance. This session will discuss applications of PTA in various aspects of subsurface CO2 storage projects.

Session 5: Advanced Machine Learning for Production Forecasting
Session Chairpersons Sebastian Matringe, Hess Corporation; Bertrand Theuveny, SLB

About 15 years ago, deep neural networks have brought a renewed interest in machine learning methods. Since then, it has been understood that the architecture of a neural network is critical to its performance and that it can be tweaked for a variety of problems. Over the past 5 years, new architectures have led to dramatic progress in the performance of machine learning methods for image, language and physics-based problems. This session will highlight a few cutting-edge projects that pertain to production forecasting using advanced machine learning methods.
