Numerical investigation of the integrity of the caprock behaviour of saline aquifers: co2 sequestration
thesisposted on 2020-08-04, 01:06 authored by Dinesh Paneerselvam
Geological Carbon Sequestration (GCS) is one of the ways to store a large quantity of CO2 in a subsurface to combat climate change. The main aim of the thesis is to expand the scope of the element-free Galerkin (EFG) method in its application to multiphase flow for CO2 injection and storage in deep saline aquifers and multiscale modelling of fracture in wet porous media within the linear elastic fracture mechanics domain. Specific objectives include an accurate assessment of stress intensity factors for varying crack lengths and the study of crack propagation in a representative reservoir rock and caprock materials.
