TCCS ninth bi-annual research meeting in Houston on March 23–24.
The Texas Consortium for Computational Seismology (TCCS) convened its ninth bi-annual research meeting in Houston on March 23–24. Nearly 60 people, including representatives from 10 sponsor companies, viewed 22 research presentations on the topics of Seismic Data Analysis, Velocity Analysis, Full Waveform Inversion, and Reverse-Time Migration. Attendees also observed a guest lecture by Professor WenZhan Song from Georgia State University on real-time seismic tomography with distributed sensor networks. Professor Song is currently visiting UT Austin as a J. Tinsley Oden Faculty Fellow. The meeting was hosted by TCCS Principal Investigator and JSG professor Sergey Fomel.

A SAGEEP field trip conducts live geophysical surveying on Lady Bird Lake beneath the Austin skyline
More than 370 geophysicists, geologists, and engineers from around the world convened in Austin March 22–26 for the 28th Symposium on the Application of Geophysics to Engineering and Environmental Problems (SAGEEP). Chaired by Bureau Senior Research Scientist Jeffrey Paine, the symposium featured 230 oral and poster presentations over three days of technical sessions, as well as short courses and forums on a variety of geophysical topics, including live geophysical surveying on Lady Bird Lake, outdoor instrument demonstrations, and a field tour of the geologic and engineering wonders of Austin led by the Bureau’s Chock Woodruff. Luncheons featured presentations on Geoscientists Without Borders, a near-surface community forum, aBureau geologist Chock Woodruff provided some levity and an expert field tour of the Austin region.nd a student career forum. Guests also saw keynote presentations on four "revolutions" influencing global politics, economics, and the environment; drought and Texas' response to it; and the discovery, excavation, and exhibition of La Salle's ship La Belle. Attendees were treated to an authentic taste of Texas during the five-day event, with a tasting tour of Texas beer and wine at Kali-Kate Ranch near Buda and Franklin Barbecue at Zilker Park. Thanks to all at the Bureau and Jackson School who supported the conference and helped make it the largest SAGEEP ever, including Dean Sharon Mosher, Scott Rodgers, Todd Caldwell, Tiffany Caudle, Lucie Costard, Jennifer Edwards, Kealie Goodwin, Kevin Befus, Jack Sharp, and Valerie Siewert.


Research Scientist Associate Daniel Enriquez and his core analysis device.
Daniel Enriquez, the Bureau’s new Research Scientist Associate and gas geochemistry laboratory technician, recently invented a device to solve a long-standing problem of core analysis. The study of in situ fluid compositions under shale reservoir conditions is problematic because volatiles can be easily lost during core drilling and post-core transport. To retain volatiles contained in the sample cores, dips and coatings such as waxes and plastics are used when cores will not be tested within a few hours or days, and when the material will be transported over long distances or requires added mechanical integrity. Accessing and accurately measuring the volatiles within the cores has been difficult, but Enriquez’s invention uses a cutting blade inside a vacuum chamber to efficiently pierce the core plug’s thick coating and capture gasses for analysis. The instrument was created in collaboration with UT’s Applied Research Laboratories and Chemistry Department. Enriquez is an alumnus of JSG’s GeoFORCE program, where he was instructed by Bureau researchers Jeffrey Paine, Sigrid Clift, and others. The program left a lasting impression on him, strongly influencing his decision to pursue his studies in geology and a career at the Bureau.
