As Technical Editor and Digital Archivist, Jacki Denison edits and archives consulting documents and serves as a general editorial resource for other departments in the company. She is also responsible for maintaining Itasca's reference library and staff information. She received degrees in both English and Spanish from the University of Minnesota Duluth.
FLAC3D TMis a numerical modeling code for advanced geotechnical analysis of soil, rock, and structural support in three dimensions. FLAC3D is used in analysis, testing, and design by geotechnical, civil, and mining engineers.
This FLAC3D V7.0 training course accommodates new and experienced users. It will be based on examples that attendees will develop and run by themselves to better grasp the mechanics of using FLAC3D V7.0, the key underlying calculation principles and the spectrum of available features. Attendees are encouraged to bring one of their specific cases that may be discussed.
The upcoming 70th annual Highway Geology Symposium will be held in Portland, Oregon, October 21st through October 24th, 2019.
Dr. Garza-Cruz is a geomechanics engineer with a background in mechanical engineering and numerical modeling. She has experience in the application of numerical models to assess the stability of mining excavations, surface subsidence, stope-back behavior, re-evaluation of underground mining method, primary fragmentation, as well as to understand the creep behavior of excavations in frozen ground.
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. Company experience covers a wide variety of completions, acquisition geometries, and treatments, employing novel processing techniques where necessary to improve the quality of information feedback to oil and gas reservoir stimulation design. As part of these services to the energy sector, Itasca runs a research and development program that has produced 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 source scanning, wave polarization analysis, point-to-point raytracing, wavefront construction, and advanced filters for signal processing.
Microseismicity (MS) monitoring is now a standard tool for evaluating the geometry and evolution of the fracture network induced during a given treatment, principally by locating MS hypocenters and visualizing these with respect to the treatment volume and infrastructure.
The combination of microseismic monitoring and analysis applied to field and laboratory observations 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 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. FNE relies on advanced techniques to model fractured rock masses and correlate microseismic field observations with simulated microseismicity generated from these models.
