... will always be required to represent collected subsurface information. However, data visualization within the geosciences is often limited to 2D slices, static views of 3D representations flattened onto a 2D plane for publication, or a predefined camera path around a 3D structure of interest. These visuals...

The goal of the study is to quantify confidence in the results using generic data from Delaware and Midland plays and using a high-fidelity 3D, fully coupled, hydraulic fracture simulator to conduct all simulations. Some differences...

In order to represent the geomechanical behavior of the fractures, Mohr-Coulomb criterion is adopted together with a traction-separation law based on the model proposed by Bandis. Parallel plate law describes the longitudinal fluid flow along the fracture...

For better representation of the travertine rock behavior observed in the laboratory, inverse analysis will be used, incorporating the Lade-Kim Model for MINPACK library in Fortran 90. The results obtained so far indicate that this model is adequate to represent the geomechanical behaviour...

The explicitly representation of faults may be done in various ways, the more classical one is via zero-thickness (or sometimes thin layer) elements inserted in-between element faces/edges while all nodal variables maintain the traditional meaning...
