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.
The Fifth International Itasca Symposium will be held at the University of Vienna (Austria). The Symposium will features the application of Itasca software for solving engineering and scientific challenges in geomechanics, hydrogeology, microseismicity, and more.
Itasca’s unique workflow uses observed microseismicity quantitatively to inform and calibrate geomechanical modeling. Microseismic geomechanics enhances the understanding and value of monitoring data by integrating geomechanics into the interpretation. It increases confidence in geomechanical modeling by ensuring consistency with field diagnostics.
Geomechanical models are constructed using rock properties and stresses computed from core log measurements, and the attributes of the microseismic events can be used to construct a model Discrete Fracture Network (DFN) based on orientation and density.
For example, synthetic microseismicity calculated during hydraulic fracturing simulations can be compared to the field-observed microseismicity. Model parameters can then be adjusted until a good match is achieved, resulting in a calibrated model that can be used to gain insights into the sensitivity of fracture geometry to geomechanical parameters, and to investigate the effects of changes in completion design.
