FlowTrans Principal Investigator
Seismologist and Research and Development Scientist, Magnitude, France
I am a seismologist and work as a research and development scientist at Magnitude, France. Magnitude is an earth science company providing comprehensive microseismic monitoring services to a range of industries worldwide including the petroleum, gas and mining industries. Commercial activities range from the long- term monitoring of mining/underground storage environments, to the monitoring of microseismicity induced by hydraulic fracturing operations.
My research focuses on the analysis of (micro-)seismic swarms, of the role of crustal fluids in triggering earthquakes, and on the retrieval of sound geomechanical information from miroseismic data. Previous research activities also includes the statistical modelling of earthquake timeseries, and the study of large earthquake sequences and long-short-range interactions.
I am the PI for the Experienced Researcher at Magnitude – Megan Zecevic.
Our FlowTrans research will focus on microseismic low-frequency events.
Hydraulic fracturing is a procedure used to increase permeability of unconventional reservoirs by injecting fluid at high pressure into the rock formation. This forced fluid flow significantly affects reservoir geomechanical properties, such as permeability and stress state. Monitoring the induced microseismicity during and after reservoir fracturing has proven to be an effective tool in characterising these changes. Recent advances in seismology suggest that together with micro-earthquakes low frequency events could have an important role in accommodating the deformation and therefore could be used to characterise fluid/rock interactions.
This research project aims at identifying and analyzing such low frequency events in hydraulic fracturing data sets to provide geomechanical information on pre-existing faults, fluids and slow deformation processes.
