Karen joined Itasca Australia in 2017, and with a background in marketing and process improvement, she provides administration support to the team and manages software sales for the region.
The main objective of this course is to demonstrate the implementation of numerical modeling and geomechanics simulation in reservoir engineering. The course focuses on the practical applications of numerical modeling for simulation and analysis of geomechanics problems such as wellbore stability, geothermal analysis, flow analysis, and hydraulic fracturing.
David is a principal geotechnical engineer with more than 20 years of operations and consulting experience in the mining and civil industries. Since joining Itasca in 2007, David has performed numerical back analyses and forward analyses for numerous open pit and underground mining operations around the world using Itasca software. David has also performed numerical analyses for several surface and underground civil infrastructure projects.
Pre-mining depressurising of a deep ore body at the McArthur River mine in northern Saskatchewan was considered to decrease the risk associated with mining near 5 MPa water pressure and increasing the amount of ore that can be extracted. Based on a limited amount of field data, a three-dimensional finite element ground-water flow model was developed to predict the amount of water that would have to be pumped from surface wells or extracted with underground drainholes to meet this goal and the associated magnitude and extent of drawdown that would propagate to the surface over the life of the operation and its impact on surface-water resources.
