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.



2015 GSP Scholarship Program Announced

Established in 2013 by the Geophysical Society of Pittsburgh, the purpose of the fund is to provide scholarships for a junior or senior undergraduate pursuing a BS degree with emphasis in geophysics and who is planning to attend graduate school where he/she will pursue a Masters or PhD degree with an emphasis in geophysics; or a graduate student in geophysics or on a geoscience tract emphasizing geophysics. In either case the student should be attending an accredited college or university in the northeast US within the boundaries of the Appalachian basin.
    Armstrong County Community Foundation (ACCF), administers the fund.  ACCF must receive the complete 2015 application packet by March 15, but you are encouraged to review the process early so you have time to assemble the required components, including information from three (3) references.

Denver to host 3D Seismic Symposium
3D Seismic: Mapping Our Future
Colorado Convention Center, Downtown Denver

The 21th annual 3D Seismic Symposium, jointly sponsored by the Rocky Mountain Association of Geologists and the Denver Geophysical Society, will be held on Thursday, February 5th at the Colorado Convention Center in downtown Denver, Colorado.  This year’s theme is “3D: Mapping Our Future”.

The submitted papers include contemporary topics for the Niobrara, Bakken, and Williston Basin unconventional reservoirs within the Rocky Mountain region.  Additional topics under consideration include 3D Seismic Attributes, Geomechanics, Microseismic, conventional plays, and examples involving analog unconventional plays across the USA, and Canada.

For more information, please contact co-chairs Mary Sue Purcell, Cambrey Cammon at or visit the website by clicking HERE.



Call for Abstracts for the 2015 Near Surface Geophysics Asia Pacific Conference

This year's conference is centrally located in Hawaii and will focus on near-surface issues within the entire Pan-Pacific region. This conference will provide a world-class forum for your new technical advances, developments, and applications in near-surface geophysics. More information can be found by clicking HERE.

Hard Rock AVO Theory and Practice





Paul McColgan, PhD
McColgan Seismic Interpretation Services, Inc.


Many in the industry have heard the term “AVO”, yet few have actually worked with it, and even fewer know what it truly means. Virtually no one is prospecting onshore seismic data with this method due to previous failures of the 1980’s; which left behind the notion that the rocks are too fast? It wasn’t that the rocks were too fast, it was more-so a problem with the lack of necessary computer power and software to accurately process and interpret pre-stack data. Pre-stack interpretation is a time intensive, data intensive, and computer intensive process. Therefore most interpreters avoid it. Onshore data has two main problems over its offshore equivalent; very high levels of noise and much higher frequencies. Both problems require intense computational time in order bring the signal quality of the data up to the levels necessary to accurately interpret for amplitude anomalies. For example, a standard processing flow for onshore AVO requires: refraction statics, surface consistent statics, pre-stack time migration (PSTM) with 30 to 60 common offsets, ground-roll attenuation, multiple attenuation, random noise attenuation, and frequency enhancement.    READ MORE
