Ileana Tibuleac, PhD Geophysics

Dr. Ileana Tibuleac has been a co-investigator on geothermal projects since 2008.  She is an observational seismologist, currently working as research assistant professor at the Nevada Seismological Laboratory, University of Nevada, Reno (UNR). Dr. Tibuleac’s current research interests include understanding 3D crustal and mantle structure in Nevada through analysis of seismic noise and tomography, developing geothermal exploration methods using ambient seismic noise and understanding earthquake generation and earthquake hazards in the Reno-Carson area. As a Southern Methodist University graduate, she has a strong background and interest in explosion and earthquake detection, location, and characterization through waveform modeling and analysis, in infrasound analysis and in array seismology.

Currently, she is working as Principal Investigator in a team with Drs. Glenn Biasi, David von Seggern and John G. Anderson to study the source characteristics of an unusually shallow earthquake sequence in Mogul, west Reno, from a discrimination perspective. Together with Dr. David von Seggern (UNR), She is developing a cost-effective, non-invasive, ambient noise – based methodology to characterize subsurface structure in a depth range of tens of meters to tens of km. The research team on this project has estimated a high-resolution model of surface wave velocity in the Reno Basin using inversion of Green’s Functions retrieved from ambient noise. For this purpose, the investigators have developed innovative ambient noise data processing algorithms, allowing the use of unconventional combinations of instruments including seismometers and accelerometers, analog instruments and geophones. As the seismic team leader, in collaboration with AltaRock Energy Inc., Dr. Ileana Tibuleac is working with David von Seggern and Glenn Biasi to develop an ambient-noise based, non-invasive methodology, to be used, in combination with other geophysical information, for characterization of Engineered Geothermal Systems potential drilling sites. In collaboration with Optim, LLC, (Dr. Satish Pullammanappallil) the investigators are developing, testing and calibrating a structural seismic exploration methodology, specifically for fault imaging, using the Earth’s reflection response retrieved from cross-correlations of ambient seismic noise recordings. Dr. Tibuleac is working with ImageAir Inc. (Dr. Mariana Eneva) on a methodology of imaging geothermal reservoirs using ambient seismic noise at Soda Lake, Nevada. Dr. Tibuleac is also working with Drs. Glenn Biasi (UNR) and Leiph Preston, from Sandia National Laboratory to build an integrated tomographic model of P, S and surface wave group velocity in Nevada for geothermal exploration purposes.

For three years, under the leadership of Professor. John G. Anderson, Dr. Tibuleac was part of a team of network seismologists working on Yucca Mountain seismic monitoring. During this time she became familiar with routine seismic network operations and with techniques used in seismic hazard estimation. For four years, in collaboration with Drs. Jessie L. Bonner and Ana Stroujkova, at Weston Geophysical Corporation, Dr. Tibuleac developed algorithms for surface wave detection and studied the influence of stochastic heterogeneity on Lg coda using waveform modeling. At Princeton, working with Professor Guust Nolet, Dr. Tibuleac analyzed and interpreted P wave amplitudes with the conclusion that focusing and defocusing in the mantle is an important factor for compressional wave amplitude variation, and this effect is underestimated by current tomographic models. While at Southern Methodist University, under the guidance of my thesis advisor, Professor Eugene Herrin, and later, together with Drs. Kent Lindquist and Roger Hansen, Dr. Tibuleac developed algorithms for small and intermediate aperture array processing and calibration.

Ileana Tibuleac received a Ph. D. in Geophysics from Southern Methodist University in May, 1999, with a dissertation entitled: “Array Measurements of P and PcP Slowness Residuals with Implications for Lateral Heterogeneity in the Lower Mantle beneath the Caribbean Sea and Other Geophysical Studies”. An article with the same title, one of the three in her thesis, was published in the journal Science. The main result of their work was identification and characterization of lateral heterogeneities in the lower mantle using data from the small aperture arrays TXAR and YKA (Yellowknife, Canada) and ray tracing.
