GEOLOGICAL APPLICATIONS FOR THE NEW FAULT RESPONSE MODELLING TOOL IN MOV
In the first case study, the predictive strength of Fault Response Modelling will be illustrated using the 2008 Nura earthquake in Kyrgyzstan (Teshebaeva et al., 2014). Fault Response Modelling will be used model displacements and stress changes that followed this magnitude 6.6 earthquake. The second and third case studies will demonstrate how fault-related fracturing modelled with the Fault Response Modelling tool can be used to reduce risk in the hydrocarbon and mining industries. In the second case study, the tool will be used to investigate the distribution of gold deposits around the Carlin fault system in northeastern Nevada, USA (Micklethwaite, 2011), and how these correlate with modelled fracture intensity. In the third case study, fault-related fractures predicted using Fault Response Modelling in the La Concepción oil field in the Maracaibo basin of Venezuela will be used to generate a discrete fracture network (DFN). The fourth case study will illustrate the potential of Fault Response Modelling as a geomechanical validation tool by comparing the displacements predicted following slip on a listric normal fault with observed hanging-wall geometries.
