[MGI33-09] 3-dimensional Fracture Network Analysis by Persistent Homology
Keywords:Topology, Data science, Mesh structure, 3D printer
Fluid flow in rocks is dominated by connectivity between fractures, so it can be expected that the relationship between fracture patterns and fluid flow can be obtained by the PH.
In this study, we quantified the images of the results from crack propagations simulation and natural mesh structures in serpentinites. The PH analysis helps to estimate the flow conditions in which the mesh structures in serpentinites were formed. And we can quantify 3D fracture structure by PH. It can be expected that PH is applied to design for geothermal reservoir by coupling PH analysis result of 3D fracture models with feature of fracture (e.g., surface area, volume, connectivity and permeability).
