Short Courses/Workshops

Return to this page often - updates are being added routinely.  Below are scheduled Short Courses and Workshops.  Note:  Some courses offered outside SAGEEP program dates of March 25-29, 2012.

Scheduled Short Courses

  • SC-1: Surface Waves Are for Everyone (Active and Passive MASW)
    Date:  Saturday, March 24, 2012, 8 a.m. to 5 p.m.
    Instructor:  Julian Ivanov, Kansas Geological Survey and Geometrics, Inc. 

    The course focuses on the practical applications of the multichannel analysis of surface waves (MASW) method, presenting the most current approaches to both active and passive estimations of 1-D and 2-D shear-wave velocity (Vs) profiles to depths of a few tens of meters using surface waves. Includes a brief theoretical overview and field procedures to ensure success, software practice using a sample data set, a brief field work session using the Geometrics Geode seismograph to demonstrate field procedures and acquire actual field data, and processing of the field data you acquire. Covers some of the latest developments in MASW analysis, including practical field-parameter estimations, multi-mode inversion and sensitivity analysis. Course goal is to build a sufficient understanding that participants are confident in applying the MASW method in their work. Participants are encouraged to bring a Windows XP/Vista/7 notebook/ laptop computer, with a screen resolution set to 1024 x 768 or better, to process short course data.  Participants will be provided with the most recent version of the SurfSeis software (i.e., 3.07) to use during the short course.
  • SC-2:  Advanced Surface Wave (MASW) Methods
    Date:  Sunday, March 25, 2012, 10 a.m. to 5 p.m.
    Instructor:  Julian Ivanov, Kansas Geological Survey and Geometrics, Inc. 

    This advanced, three-quarter day course will cover various practical topics related to data acquisition and analysis, such as, optimum field spread-size determination, fixed-spread data acquisition (useful when having extra geophones), muting for enhance- ment of dispersion-curve images, inversion sensitivity, and advantages of a-priori density information. Additional topics can cover case studies (e.g., studying levees, mapping fault zones), challenging dispersion-curve patterns, and most recent MASW advancements, such as HRLRT for dispersion-curve imaging and multi-mode inversion. It is expected that participants will use their own laptops with SurfSeis 3 installed and licensed.
  • SC-3: Electrical Resistivity/IP/SP for Environmental and Engineering Applications
    Date:  Sunday, March 25, 2012, 8 a.m. to 5 p.m.
    Instructor:  Bradley J. Carr,  PhD, Advanced Geosciences, Inc.

    Electrical Resistivity/IP/SP for Environmental and Engineering Applications is designed for professionals who are involved in, beginning to consider, or have oversight/review responsibilities of others currently conducting DC Resistivity, IP or SP surveys.  This short course will cover DC Resistivity, IP, and SP topics such as: theory; data acquisition; field procedures; data processing; data presentation; and interpretation.  The course will also provide attendees a better understanding of the strengths of 1D, 2D, 3D and 4D resistivity/IP imaging and SP monitoring methods through the discussion of various case histories, survey design, forward modeling and inversion and the use of data processing/analysis software as applied to surface, borehole, marine and  time-lapse monitoring data .
     

Scheduled  Workshops  

  • Trends in Resistivity and IP for Shallow Applications
    Date: Thursday, March 29, 2012, 8 a.m. to 5 p.m.
    Convenor:  Norman R. Carlson, Zonge International, Inc.

    Near surface geophysics is arguably the fastest growing area of research and development as it provides distinct advantages over traditional, more time-consuming investigation methods such as drilling, sampling and trenching. Geophysical techniques are less expensive and offer the opportunity to continuously image the subsurface.  Advances in instrumentation design, computer hardware and data processing software have all contributed to the development of novel and highly sophisticated imaging techniques. This workshop focuses on the application of resistivity and IP over a wide range of scales for geotechnical and geoenvironmental investigations.
  • W-2: Hydrofracking 101: What is it, What are the Issues, and How Can Geophysics Help?
    Date: Thursday, March 29, 2012, 8 a.m. to 5 p.m.
    Convenors: Mike Jacobs, Pioneer Natural Resources; Charles G. Groat and Jeffrey G. Paine, The University of Texas at Austin; and Bruce Smith, U. S. Geological Survey

    Hydrofracking is a hot-button topic among industry groups, regulators, and citizens in many parts of the U.S. where it is being used to enhance hydrocarbon production from vertical and horizontal wells. Issues of concern related to hydrofracking include ensuring an adequate water supply, monitoring of fracking operations, induced seismicity, and possible water-quality impacts, yet few outside industry understand the hydrofracking process. This workshop is intended to educate attendees on the hydrofracking process, issues of concern, and geophysical approaches to addressing those issues. Topics to be covered include an introduction, history, and description of the types of hydrofracking; possible impacts associated with injection, water use, and the fracturing process; current geophysical monitoring of hydrofracking; and geophysical approaches that could address issues of concern to regulators and the public.
  • W-3: Seismic Refraction Methods: Unleashing the Potential and Understanding the Limitations
    Date: Thursday, March 29, 2012, 8 a.m. to 5 p.m.
    Convenors: William E. Doll, Battelle; Seth Haines, U.S. Geological Survey; and Colin Zelt, Rice University

    Speakers will include Derecke Palmer (Univ. New South Wales, Australia), Julian Ivanov (Kansas Geological Survey), Priyank Jaiswal (Oklahoma State), and Colin Zelt (Rice University).

    Seismic refraction tomography is widely used to address a broad range of near-surface problems. Many practitioners hold tomographic methods in high regard, because these approaches typically yield a velocity model that is simple (smooth) and that is thought to be more representative of near-surface structures than blocky or layered models.  Some have raised concerns with smooth models and suggest that a layered model is more appropriate. Others focus on starting models, and contend that the use of simple or otherwise inappropriate starting models can bias the outcome of the inversion. Still others believe that the best approach is to apply different inverse methods in order to elucidate the range of model nonuniqueness. We will discuss concerns regarding tomographic analysis and we will describe algorithms that address these issues. In addition, we will explore emerging opportunities for improved refraction solutions, including full waveform and three-dimensional methods. Contributed presentations will be included in the afternoon session and a panel discussion will round out the day.
