Mr Lachenicht has 25 years’ experience in mining geomechanics ranging from consulting, research projects, studies to mine operational experience. Over the course of his experience, positions held include manager, senior geotechnical engineer, geotechnical superintendent and principal geotechnical engineer roles with associated levels of responsibility.
Dr. Sharrock has 15 years industry experience in a wide range of rock mechanics positions such as Principal Geotechnical Engineer (Newcrest Mining NL), Rock Mechanics Engineer (Mt Isa Mines), Senior Geotechnical Consultant (AMC Consultants), Senior Lecturer in Geotechnical Engineering (UNSW) and Associate Professor - Caving Geomechanics (UQ).
XSite is a powerful three-dimensional hydraulic fracturing numerical simulation program based on the Synthetic Rock Mass (SRM) and Lattice methods. XSite is capable of modeling multiple wellbores with multiple stages and clusters, including open-hole completions and perforation tunnels. XSite resolves general hydraulic fracture interaction, including propagation in naturally fractured reservoirs with deterministically or stochastically generated discrete fracture networks (DFNs). The models conduct fully coupled hydro-mechanical simulations. Fluid flow is simulated as fracture flow within the joint networks and as matrix flow within the intact rock. Proppant transport and placement logic is included. Proppant affects fracture closure and fracture conductivity. General pumping schedules can be simulated with switching injected Newtonian or power-law fluids. The borehole flow is coupled with the rest of the model to determine distribution of fluid between multiple clusters. Synthetic microseismicity can be tracked and recorded.
