Webb15 feb. 2024 · The first case assumes that there are no high-permeability faults acting as pathways. A slow upward migration of gas occurs to form a hydrate zone above the gas layer . The migration of gas occurs due to buoyancy, and the absence of faults makes the process slow. The total hydrate mass reached 3 × 10 7 kg per unit cross-section depth. WebbThe initial permeability of a fault is influenced, first and foremost by the partitioning of dilational and shear strain that, in turn, determine the size or aperture of the conduit, …

"WebbTemperatures exceed 640 ?F (~338 ?C) at a depth of less than 10000 feet (3 km). Permeability varies throughout the geothermal field due to the competing processes of alteration and mineral precipitation, acting to reduce the interconnectivity of faults and fractures, and the generation of new fractures through faulting and brecciation.
