Phase-Field Simulation of Near-Wellbore Nucleation and Propagation of Hydraulic Fractures in Enhanced Geothermal Systems (EGS)

Conference SPE Reservoir Simulation Symposium Proceedings · January 1, 2023 Enhanced geothermal systems (EGS) rely on the artificial creation of fractures (i.e., hydraulic fractures) to enhance the permeability of the formation which would, otherwise, be too low to allow for fluid circulation. Hydraulic fracturing involves complex ... Full text Cite

Phase-field modeling of hydraulic fracturing under heterogeneities and/or layering of rock properties and in-situ stress

Conference 57th US Rock Mechanics Geomechanics Symposium · January 1, 2023 Hydraulic fracturing is a process of creating artificial fractures to enhance the hydraulic conductivity of nearly impermeable rock masses, enabling an economic development of many subsurface energy systems. Due to heterogeneities and layering of rock prop ... Full text Cite

Pellet cladding mechanical interaction modeling using the extended finite element method

Conference Top Fuel 2016 Lwr Fuels with Enhanced Safety and Performance · January 1, 2016 Fracturing of ceramic light water reactor (LWR) fuel has multiple important effects on fuel performance. One particularly important concern is that cracks in the fuel cause elevated stresses in the cladding when pellet cladding mechanical interaction (PCMI ... Cite
