Welcome

The Geophysical Society of Pittsburgh is a nonprofit organization dedicated to promoting the science of geophysics in the Appalachian Basin. We are an official section of the Society of Exploration Geophysics (SEG). Monthly meetings are generally held from September to May on the first Tuesday of each month at various locations around the Greater Pittsburgh area. However, be sure to check the event calendar as exceptions to this rule occur often. All interested parties are encouraged to attend.

The complexity just below our feet and the implications for the fidelity of land seismic data
Presented by Christine Krohn

2018 Honorary Lecturer to North America


Abstract: State-of-the-art seismic methods, such as reservoir property estimation, time-lapse and Full Wavefield Inversion (FWI), are becoming routine in deep-water environments. Land data, however, presents challenges, particularly when we consider the need for low-cost acquisition for unconventional plays. This talk will focus on the inadequacies of common assumptions make about the “so called” weathering layer of the earth. More fully incorporating the true complexity of the near surface in seismic processing is needed before data recorded in land environments can approach the fidelity of data recorded in marine.

Speaker Biography: Christine Krohn (Chris) retired from ExxonMobil Upstream Research Co. after a 36-year career in geophysical research. Before that, she earned a Ph.D. in condensed matter physics from the University of Texas at Austin in 1978. During her career, Chris organized many research workshops, chaired the SEG Research Committee, and served as a director-at-large on the SEG board of directors. Presently, she is Geophysics associate editor responsible for the Bright Spots in Geophysics column in TLE. In 2015, She was the 21st Milton B. Dobrin Memorial lecturer at the University of the Houston, and in 2016 she was awarded Honorary Membership in the Geophysical Society of Houston and Life Membership in the SEG. Her publication on surface-wave tomography was awarded Best Paper in Geophysics in 2017. She now lives in Durham, NC.
