Paul Sava is new CWP Director

Paul Sava CWP is pleased to announce that Paul Sava has become the new CWP Director as of August 1, 2014. He succeeds Prof. Dave Hale, who served as CWP Director since 2011.

Prof. Sava is an Associate Professor of Geophysics at the Colorado School of Mines. 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 recipient of a Stanford Graduate Fellowship (1997-2000) from Stanford University and of a Jackson Young Scientist Fellowship (2006-2007) from the University of Texas (Austin). He is also a recipient of three Awards of Merit for best student presentations at the Society of Exploration Geophysicists (SEG) conventions (1999, 2001 and 2004) and of a Honorable Mention in the Best Paper in GEOPHYSICS category (2003) for "Angle-domain common-image gathers by wavefield continuation methods," co-authored by Sergey Fomel. The SEG recognized him in 2007 with the Reginald Fessenden Award for his work on wave-equation angle-domain imaging. He is a member of SEG, EAGE, and AGU, and is currently serving his second term as Education Officer on the EAGE Board.

 

Ilya Tsvankin teaches seismic anisotropy to CNOOC geophysicists

On July 18, CWP professor Ilya Tsvankin taught a training course focused on seismic anisotropy and its applications in the hydrocarbon industry to a group of geophysicists from Chinese National Offshore Oil Company (CNOOC). The 30-member CNOOC delegation was visiting the Colorado School of Mines for a two-week training in seismic data processing organized by Dr. Fred Wang from the University of Texas at Austin. In addition to Prof. Tsvankin, instructors included Drs. Walt and Heloise Lynn and Profs. Sergey Fomel and Manika Prasad.

Ilya Tsvankin serving on 16IWSA Technical Committee

16IWSAIlya Tsvankin CWP professor Ilya Tsvankin is lending his expertise to the 16th International Workshop on Seismic Anisotropy (16IWSA) as a member of the Technical Committee. Ilya will also give a keynote lecture at the workshop. The 16IWSA will be held in Natal, Rio Grande do Norte, Brazil, on November 16-21, 2014. The workshop, organized by a group of Brazilian geophysicists from both industry and academia, marks its inaugural occurrence in South America. The focus of the workshop is on methods for seismic data processing in anisotropic structures with applications to oil and gas exploration, reservoir monitoring, and earthquake seismology. The abstract submission deadline is July 30, 2014; visit the 16IWSA website for more information.

Loralee Wheeler is a four-time recipient of SEG scholarships

Loralee Wheeler CWP student Loralee Wheeler has received multiple SEG scholarships throughout her time at Colorado School of Mines. SEG assisted Loralee in pursuing her educational goals, when as an incoming freshman, she received the J.E. White Scholarship for her aspiration to study volcanism upon graduation. After a couple of years, Loralee turned her sights toward seismic exploration and was awarded the Anadarko Scholarship and later the Henry Bates Peacock Scholarship, both also offered through SEG. With the help of SEG and the scholarship donors, she has been able to achieve two of her academic goals so far: Loralee received her bachelor of science degree in geophysics in May 2013, and she was admitted into the Master of Science graduate program at CWP in August 2013.
