... fracture geometry during Sc-CO 2 fracturing. Even under a high vertical stress difference of 8 MPa, Sc-CO 2 can still open some low strength bedding planes and create multiple hydraulic fractures. With the decrease of horizontal stress difference, the number of fractures formed by Sc-CO 2 fracturing...

...-kinematic sediments are modelled as poro-elastoplastic materials using a modified Cam-Clay critical state model and the mobile shale is modelled as visco-plastic Herschell-Bulkley material, at critical state. The results show that the atypical geometries of the fold strata can be explained...

ABSTRACT: In this study, 3DEC modeling in conjunction with the Discrete Fracture Networks (DFNs) technique was performed to better understand the behavior of shearing faults in a relatively large-scale direct shear test model. The DFNs explicitly generated two different geometries of the fault...
