Research

Primary Research Areas:

• Enhanced Geothermal Systems (EGS) Development:

We investigate advanced hydraulic stimulation techniques to enhance and sustain permeability in low-porosity geothermal reservoirs. Our work focuses on understanding the coupled thermal, hydraulic, and mechanical (THM) processes that govern fluid flow and heat extraction over time, aiming to improve the efficiency and long-term viability of EGS-based geothermal energy production.

• Induced Seismicity: Interpretation and Mitigation:

We study the physical mechanisms that control the spatial and temporal evolution of induced seismicity during fluid injection. By examining the relationships among fracture deformation, frictional behavior, permeability changes, and seismic responses, we aim to develop effective strategies for seismic risk mitigation and leverage seismic data to characterize fracture networks and fluid flow behavior.

• Geomechanical Aspects of Critical Minerals Extraction:

We investigate the coupled geomechanical and geochemical processes involved in extracting critical minerals from deep reservoirs. Through integrated experimental and numerical approaches, we analyze rock-fluid interactions, mineral dissolution and transport, and rate-dependent deformation to enhance fracture connectivity and mineral recovery efficiency.

• ML/AI for Drilling and Stimulation Optimization:

We apply machine learning (ML) and artificial intelligence (AI) techniques to optimize drilling and hydraulic stimulation operations. Our research includes real-time prediction of fracture and flow behavior, drilling rate enhancement, early detection of operational anomalies, and optimization of stimulation parameters. By integrating field data with physics-informed learning, we aim to improve decision-making, reduce risk, and increase the efficiency of subsurface energy development.

• Shale Oil and Gas Resource Development:

We develop and evaluate novel proppant materials for hydraulic fracturing in shale formations, aiming to improve fracture conductivity and well productivity. Additionally, we focus on the interpretation of Diagnostic Fracture Injection Tests (DFIT) and minifrac tests to reliably estimate in-situ stress and reservoir properties for stimulation design.
