Microseismicty and Heavy-Oil/Shale-Gas Extraction
Dr. Mirko van der Baan
Microseismic events are very small earthquakes that can be associated with fracturing and fluid flow in reservoirs. Long-standing applications of microseismic methods include monitoring of shaft stability in mines and the creation of engineered geothermal systems. These methods are also being used increasingly by the oil and gas industry to monitor hydraulic stimulation of “tight” hydrocarbon reservoirs, and steam-injection in heavy-oil fields. As such, it is one of the technologies underpinning the recent revival of conventional oil production in Western Canada, as well as the development of new tight-gas and tight-oil fields, and monitoring of caprock integrity during in situ heavy-oil exploitation. This talk reviews our current understanding of seismological and geomechanical processes associated with induced microseismicity and how it can be used for optimized hydrocarbon recovery.
Mirko van der Baan joined the Department of Physics at the University of Alberta in October 2008. Mirko graduated in 1996 from the University of Utrecht in the Netherlands, obtained a PhD with honors in 1999 from the Joseph Fourier University in Grenoble, France, and then joined the University of Leeds, UK, where he became the Reader of Exploration Seismology. He also holds an HDR (Habilitation) from University Denis Diderot, Paris, France.
Mirko is the Principal Investigator of the joint-industry projects on Blind Identification of Seismic Signals, focusing on advanced statistical signal processing and technology/knowledge transfer to the hydrocarbon industry; and the Microseismic Industry Consortium, a collaborative venture with the University of Calgary, dedicated to research in microseismicity.
