Field Trip #6: Hands-On Geophysical Data Acquisition – Characterizing Shallow Gulf Coast Sediments Using Cuttings, Well Logs, and Seismic Surveys (1-Day)

Conference registration is required for enrollment in field trips and short courses, with the exception of the More! Rocks in Your Head teacher program. See the Registration page for details on registration options. Save with Early Bird rates until August 16th!

Dr. Robert Stewart (University of Houston and Director of Allied Geophysical Labs) will lead a one-day course about geophysics on Sunday, September 20, 2015 (8:00 am – 4:00 pm). Participants will learn about acquiring geophysical signals and will also do live seismic acquisition with U of H equipment. This course will be a fun way to learn seismic acquisition by doing hands-on experiments and seeing the results. Departure from and return to the Hilton Americas.

Maximum number of participants: 20 (4 Student spots)

Cost: $250 per person; $50 for students (includes transportation, lunch and refreshments, and guidebook)

This hands-on course will introduce participants to the methods of subsurface imaging and geologic integration using two shallow test wells drilled near La Marque, Texas at the University of Houston’s Coastal Center. The two wells penetrate 425 ft of Quaternary (Beaumont Formation) sediments, including several sand aquifers. Cuttings, recovered from the wells, will be viewed. Participants (with instructor assistance) will log one of these wells with sonic, resistivity, and gamma ray tools. We will also conduct a vertical seismic profile (VSP) survey in the other well using an impact surface seismic source. A vibroseis truck will be used to acquire seismic data with geophones planted (by the participants) on the surface. The cuttings, well logs, and VSP will be used to interpret the reflections, in particular the sands, on the surface seismic data. Participants will gain an understanding of the fundamentals of well logging and seismic techniques in addition to data integration.
