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.

Cracking The Code: Fracture Detection Without Anisotropy
Bill Wepfer, Eskaton Seismic

Abstract: Fracturing in shales. In some resource plays, these fractures are the key to making a good well. In other shales, fracture avoidance is paramount for proper fracking. Is specialized & expensive acquisition & processing required, generating a host of volumes to bury the already busy interpreter? Can these sub-seismic cracks be reliably detected, & in such a way that someone other than a specialist could readily employ the results? Could it even work on 2D, the ultimate in no azimuthal coverage? DOWNLOAD FULL ABSTRACT



Bill Wepfer
Eskaton Seismic


Biography: Bill Wepfer earned his B.S. in Physics (1983) from Miami University (Ohio), then his M.S. in Physics (1984) & his Ph.D. in laboratory rock physics (Geophysics) from Purdue University in 1989.  Afterwards, he worked for Amoco (now part of BP) in Houston doing onshore AVO, ultimately leading a nine member technical group.  Upon exiting Amoco in 1997, he joined Brigham Exploration (now part of Statoil) in Austin, continuing his onshore AVO efforts.  Throughout this period, Bill was heavily involved in the seismic efforts, realizing that the core of the amplitude problems lay in the proper processing of problematic, low S/N land data.  He left Brigham in 2000 to join AXIS Geophysics (afterwards part of GX Technology / IO, later Ion, & now part of NEOS) as the fledgling company’s processing manager.  Bill moved to Echo Geophysical (purchased in 2013 by SEI) in 2004 as a senior seismic analyst. In 2006, he moved outside of Raleigh to marry a North Carolina native, & he processed seismic from home for Echo until 2012. In early 2012, Bill formed Eskaton Seismic to help support a local charity. He has three stepchildren ages 24, 23, & 15, plus 1 adopted child, age 4.
