NEW Special Interest Group:

NOTE: You Must be Logged In to Register.
*** The GSH is proud to announce the formation of a new Special Interest Group called the Unconventional SIG. This new SIG aims to provide a forum for discussion of any technology or workflow or case study having to do with unconventional oil and gas exploration, exploitation, and production, with an emphasis on geophysics and how it can be integrated with other disciplines such as geology and engineering.
The Unconventional SIG is being sponsored by TGS and will meet in their office building on Clay Rd, just off of the Beltway north of I-10. It will meet every other month, alternating with the Microseismic SIG.

Speaker Update: Marianne Rauch-Davies, co-author
Mike Perz, Director Technology & Innovation, TGS
As with most emerging technologies, pre-stack depth migration (PSDM) for unconventionals has suffered from a certain amount of overhype, leaving many practitioners confused as to what might be the true value of its application. The reality is that while PSDM can produce jaw-dropping improvements in structured offshore settings, advantages are less clear-cut in onshore unconventional settings, where the input data are typically less structured and noisier. However, despite their relatively subtle presentation, these advantages can be significant, coming in the form of improved velocity model determination, increased accuracy in event depthing, as well as enhanced fault resolution, all of which are of vital importance for horizontal well planning and steering. This presentation will provide a no-nonsense view of PSDM-for-unconventionals technology and will demonstrate its value via multiple real data examples and via comparison of PSDM cost versus cost of out-of-zone drilling.
Speaker Biography: Marianne Rauch-Davies
Marianne received her PhD in Physics in 1985 from Uni Graz in Austria. She started her oil career as research assistant at Curtin University in Perth, Australia 30 years ago and has been active in geophysics ever since then. Marianne lived in many places and worked on-shore and off-shore basins all over the world. Her main specialties are DHI, seismic processing, depth migration, potential fields and researching new technologies, methodologies. She likes to do applied research, mentor and teach and is a seasoned presenter at conventions and workshop. She has published a good number of articles on a number of subjects and still is passionate about geoscience and the thrill to get more and unique information out of geophysical measurements that help drilling more successful wells.
Mike Perz, TGS
Mike Perz holds a BSc in Physics (University of Toronto) and an MSc in Geophysics (University of British Columbia). Upon graduating in 1993, he joined Pulsonic Geophysical as a seismic processing applications programmer, and four years later moved to Geo-X Systems Ltd. (later Divestco Inc.), first writing code then managing the processing R and D group. In 2010, Mike joined Arcis Corporation where he was employed as Vice President of Technology and Integration at the time that organization was purchased by TGS in 2012. He remains at TGS to this day, and his current title is Director, Technology and Innovation, a role whose primary mandate is to demonstrate the value of seismic in unconventional resource development. Mike’s research interests have historically spanned all elements of land processing, including deconvolution, interpolation, azimuthal imaging, and, most recently, pre-stack depth migration.
