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.
Itasca has been involved in the real-time monitoring, post-processing and quality assurance of enhanced oil recovery projects using single and multi-stage hydraulic fracturing. Experience in the field includes a wide variety of completions, acquisition geometries and treatments, and employing novel processing techniques where necessary to improve the quality of information fed back to oil and gas reservoir stimulation design. As part of these services to the energy sector, Itasca runs a research and development program which has produced the development of advanced algorithms to locate seismic sources using geometrically limited arrays (such as geophone strings in a single borehole) and under low signal-to-noise conditions using wave polarization analysis, point-to-point raytracing, wavefront construction, and advanced filters for signal processing.
MS monitoring is now becoming a standard tool for evaluating the geometry and evolution of the fracture network induced during a given treatment, principally by locating hypocentres and visualizing these with respect to the treatment volume and infrastructure. The combination of microseismic monitoring and analysis with state-of-the-art geomechanical simulations offers a unique and powerful method of understanding in-situ rock mass behavior. The modeling allows predictions of the rock response to be made based on the properties obtained from laboratory experiments. The microseismic data is then collected in the field to validate the model. Appropriate refinements are made to the model to provide a realistic interpretation of the true behavior. This combination is essential for the concept of fracture network engineering (FNE) which involves the design, analysis, modeling, and monitoring of infield activities aimed at enhancing or minimizing rock mass disturbance.
