News & Events - 2015
Christoph Sens-Schönfelder from the German Research Center for Geosciences (GFZ) in Potsdam, Germany, is visiting Prof. Roel Snieder at CWP for two weeks during the summer of 2015.
During Dr. Sens-Schönfelder's visit, he will continue the research that he and Prof. Snieder started when Prof. Snieder was on a sabbatical leave at GFZ in the fall of 2014. This collaboration was a result of the research award from the Alexander von Humboldt Foundation that Prof. Snieder received.
Ilya Tsvankin and the Anisotropy (A-) Team have begun working on a three-year international research project titled "Full waveform inversion of seismic data for reservoir attributes." The project is funded by the King Abdullah University of Science and Technology (KAUST), Saudi Arabia, as part of the Competitive Research Grant program designed to support cutting-edge developments in all fields of science. The A-Team collaborators include Tariq Alkhalifah (project coordinator) and Ying Wu (KAUST), Jiubing Cheng (Tongji University, China), and Ehsan Naeini (Ikon Science, United Kingdom). The main goal of the project is to develop advanced anisotropic target-oriented FWI algorithms capable of estimating the physical parameters of oil and gas reservoirs from multicomponent, wide-azimuth seismic data.
On June 11 in Berlin, the Alexander von Humboldt Foundation presented Roel Snieder with a laudation for his internationally-recognized contributions to the fields of acoustic/seismic exploration and seismology. Snieder's work on seismic interferometry was also recognized by the von Humboldt Foundation. Prof. Snieder's award, presented by Dr. Helmut Schwartz, the von Humboldt Foundation president, also highlighted the collaboration between Prof. Snieder and Dr. Christoph Sens-Schonfelder at the German Research Center fro Geosciences (GFZ Potsdam), as well as with Dr. Ernst Niederleithinger at the Federal Institute for Materials Research and Testing (BAM) in Berlin. Congratulations, Roel!
On June 1, Paul Sava was named the C.H. Green Chair of Exploration Geophysics at the Colorado School of Mines. Prof. Sava is also the current Director of CWP. He holds an Engineering degree in geophysics (1995) from the University of Bucharest, and a MS (1998) and a PhD (2004) in geophysics from Stanford University, where he was a member of the Stanford Exploration Project. His main research interests are in wavefield seismic imaging, stochastic imaging and inversion, computational methods for wave propagation, numeric optimization and high performance computing. He is a member of SEG, EAGE, and AGU, and is currently serving his second term as Education Officer on the EAGE Board.
The Center for Wave Phenomena thanks all representatives from our Consortium sponsor companies who attended the 2015 Project Review Meeting of the Consortium Project on Seismic Inverse Methods for Complex Structures. CWP welcomed representatives from all over the globe who generously support our geophysics research. Please contact Shingo Sean Ishida if you need any resources or materials distributed during the meeting.
This summer, five new graduate students will join the Center for Wave Phenomena:
- Lucas Andrade, Brazil (Advisor: Prof. Paul Sava)
- Xueyi (Alex) Jia, China (Advisor: Prof. Roel Snieder)
- Qifan Liu, China (Advisor: Prof. Ilya Tsvankin)
- Ivan Lim Chen Ning, Malaysia (Advisor: Prof. Paul Sava)
- Aaron Prunty, USA (Advisor: Prof. Roel Snieder)
On April 8, 2015, Loralee Wheeler successfully defended her Master of Science thesis at the Colorado School of Mines. Loralee's thesis is titled "Automatic and simultaneous correlation of multiple well logs." She conducted her research under Prof. Dave Hale, her CWP advisor. Following her departure from Mines, Loralee has begun working at Chevron Energy Technology Company in Houston, Texas. Well done, Loralee!
Roel Snieder recently completed a tour of the Middle East to present his popular "Art of Science" lecture. Prof. Snieder travelled to six venues across Iran, Qatar and the United Arab Emirates during his February lecture tour for the European Association of Geoscientists and Engineers (EAGE). His presentations were very well received (see tour photos below). The lecture series was organized by EAGE Local Chapter Iran, as well as the Iranian Geophysical Society. Snieder's lecture - given as interactive conversations with participants - are aimed at junior researchers and their mentors in all fields of science and engineering so they may acquire the necessary skills to focus on building understanding, capability and confidence in communication, planning, time management, problem solving, leadership and assertiveness. Snieder also placed an emphasis on the skills required of researchers for successful self-management and development during their respective courses of study.
On February 6, 2015, Oscar Jarillo Michel successfully defended his Master of Science thesis at the Colorado School of Mines. Oscar's thesis is titled "Estimation of microseismic source parameters by anisotropic waveform inversion." He conducted his research under the guidance of Prof. Ilya Tsvankin. This thesis defense also constituted Oscar's first comprehensive examination of his PhD in geophysics; for which he will continue working with Prof. Tsvankin. Congratulations and well done, Oscar!
On December 11, 2014, CWP alumnus Filippo Broggini, PhD, was honored at the 2014 Gustavo Sclocchi Awards ceremony for his thesis titled "Wavefield autofocusing and applications to multidimensional deconvolution and imaging with internal multiples." The Gustavo Sclocchi Awards, a joint initiative of the Society of Petroleum Engineers (SPE) Italian Section, European Association of Geoscientists and Engineers (EAGE) and Assomineraria (Italian Petroleum and Mining Industry Association), recognize the best theses in geosciences and petroleum engineering by graduates from Italian universities and/or Italian nationals graduating from universities around the world. Winning theses must be related to hydrocarbons, geothermal exploration, or production activities. As one of six 2014 winners, Dr. Broggini delivered a short presentation on his thesis during the award ceremony, received a prize of 2400 Euros, as well as a free, one-year EAGE/SEP membership. Congratulations, Filippo!
For Consortium Sponsor representatives only. If you wish to reserve paper copies of the 2015 Project Review book, please respond to Shingo with your requested quantity by Wednesday, April 1, 2015. Your reserved copies will be provided at the CWP Project Review Meeting on May 11-14, 2015. As in previous years, CWP will provide electronic copies of the Project Review book, individual research reports, and other CWP documents on a password-protected webpage, as well as on USB drives distributed during the meeting. Please contact Shingo if you have any questions and thank you for your support of the Consortium.
The technical presentation by CWP PhD student Yuting Duan (left) titled "Converted-waves imaging condition for elastic reverse-time migration," was ranked in the top 30 papers presented during the 2014 SEG Annual Meeting in Denver, Colorado. The collaborative work between Duan and Paul Sava (right) was selected out of thousands of presentations at the SEG meeting. Congratulations and well done!
CWP student Satyan Singh (far left) will visit the Delft University of Technology (TU Delft) in The Netherlands, from January 14 to February 27 to collaborate on his research on 2D autofocus imaging in the presence of a free-surface. He will work closely with the TU Delft seismic imaging team, led by Dr. Kees Wapenaar (center left), as well as with Drs. Joost van Der Neut and Evert Slob (center right, right), in the Department of Geosciences and Engineering. Satyan will also continue his PhD research on Green's function retrieval using Marchenko-type equations and their applications. His previous collaboration with Prof. Wapenaar and Drs. van der Neut and Slob produced a submitted paper to GEOPHYSICS called "Autofocus imaging: Imaging of primaries, internal multiples and free-surface multiples."
