Conrad Newton successfully defends his MSc. thesis

On May 16, 2012, Conrad Newton successfully defended his Master's thesis at the Colorado School of Mines. His thesis is titled "Estimating intrinsic attenuation from seismic interferometry and time reversal."

Nature Magazine and AGU Journal of Geophysical Research highlight Nakata and Snieder's research on near-surface shear wave velocities in Japan 

 

Shear-wave velocities estimated by annual stacked seismic interferometry

Seasonal variation in shear-wave velocity with precipitation in southern Japan

The occurrence of earthquakes and even heavy rainfall reduce the near-surface velocity of a type of seismic wave responsible for the worst damage during earthquakes. Nori Nakata and Roel Snieder studied "shear" waves using seismic interferometry, which measures how the waves propagate from depth to the surface. The authors analysed the average velocities of shear waves in nearly 112,000 quakes — most of them minor — recorded between 2000 and 2010 by KiK-net, Japan's network of seismic stations. They found that, three months after major earthquakes, wave velocities recorded at nearby stations were 3–4% lower than normal. Follow these links to see more about Nakata and Snieder's research in Nature and the Journal of Geophysical Research.

 

Update: Behura to lead CWP Tutorial at May 2012 Project Review Meeting

Jyoti's tutorial is titled, "Attenuation anisotropy: Analysis and estimation." The tutorial will address basic aspects of seismic wave propagation in the presence of attenuation anisotropy and discuss methodologies for estimating the attenuation anisotropy parameters from field data. To attend the tutorial, send an RSVP to Pam Kraus, CWP program assistant. See more information about the project review meeting here.

E&P Magazine highlights Tsvankin's fracture characterization research

RoelTeachingThe February 2012 edition of Hart Energy's E&P Magazine features Ilya Tsvankin and his Anisotropy-Team's research on seismic fracture characterization. The article, by E&P senior editor Rhonda Duey, discusses the role of geophysical methods in "unconventional" shale oil and gas plays. Mapping areas of high fracture density from seismic data helps identify "sweet spots" of increased production in many shale reservoirs. Tsvankin's group is developing seismic inversion and fracture-detection methods based on realistic azimuthally anisotropic models of fractured formations.
