Fluid flow through microcracked and fractured granitic reservoirs
Marie Estelle Solange Violay, Lucille Jocelyne Nadine Carbillet, Michael Heap
The permeability of crustal rocks and rock-masses dictates the efficiency of hydrothermal circulation and therefore the productivity of geothermal resources. In this study, we find by monitoring P-wave velocity that thermal microcracking in Lanhélin granit ...
2023To break or not to break: The role of secondary mineralisation on joint reactivation in sandstone
Alexandra Roma Larisa Kushnir, Michael Heap
Discontinuities, including fractures and joint sets, modify the fluid transport properties and strength of rock masses. While open fractures and joints increase rock mass permeability and decrease rock mass strength, fluid flow within these structures can ...
2023Experimental Investigation of Hydraulic Fracture Closure in a Porous Sandstone
Brice Tanguy Alphonse Lecampion, Seyyedmaalek Momeni, Mohsen Talebkeikhah, Guanyi Lu
Depending on the type of fracture propagation regime when the injection stops, the closure of the fracture may occur exactly after the injection ceases, in the case where the fracturing process is dominated by fracture energy, or the fracture propagate for ...
