Kanu received his Bachelor of Science degree in physics from Michael Okpara University of Agriculture, Nigeria. He then earned a post-graduate diploma in earth system physics at the International Center for Theoretical Physics (ICTP) in Italy. In 2008, Kanu began work on his Master of Science degree in geophysics at Indiana University, Bloomington. His research focused on modeling the creep response of the Southern Hayward Fault to the 1989 Loma Prieta earthquake on the San Andreas Fault.

His current research interests are in monitoring time-lapse changes in sub-surface reservoirs and microseismicity. He is currently working with Prof. Roel Snieder, his advisor at CWP.

Apart from research, Kanu follows and plays various sports and also explore the beautiful mountains within Colorado.

 

Research

Kanu's research interests are: microseisimicity, fractured reservoir characterization, and fault friction. He is currently working on a project which involves the use of microseismicity for time-lapse monitoring of two reservoirs. The reservoirs are the Paradox reservoir and the Coso geothermal reservoir.

The Paradox reservoir, which is located at Southwestern part of Colorado, is used to divert salt water flowing on one the tributaries that runs into the Colorado river. The diversion prevents the salt water from contaminating the Colorado river. The diversion involves an injection of the fluid into the Paradox reservoir which has been creating a lot of microseismic events for over the past 15 years. Likewise, the Coso field, which is an enhanced geothermal field is generating a lot of events with magnitudes less than M3.0. Coso field is located in California along the western boundary of the Basin and Range, Western US. In this project, Kanu is using strongly similar events whose locations are separated by few meters to monitor for possible time-lapse changes within both reservoirs. These events are believed to be repeating events. He is looking at the coda (scattered) section of the waveforms for imprints of changes that have occurred within the reservoirs. To do this, Kanu is using and developing tools in coda wave interferometry, which can be used to characterize changes in velocity and scattering properties of the subsurface. This project is sponsored by the US Department of Energy (DOE).
