  Join Us for GST’s November “Gathering of Minds”

  Dear GST Members,

  We’re excited to invite you to our next Geophysical Society of Tulsa “Gathering of Minds.”

  When: Thursday, November 13, 2025
  Time: 11:30 AM – 1:00 PM
  Where: Baxter’s Interurban Grill (main dining area)

  At our October gathering, conversation flowed from how Phillips got its start and early industry stories to the evolution of computing systems and programming languages that came long before Python. It was a great reminder of how much experience and history our members bring to the table.

  This month, we’ll keep that same open format — an informal time to connect, share ideas, and talk about whatever topics spark interest. Whether it’s geophysics, geology, weather, or something a little lighter like pets or hobbies, all are welcome.

  Our goal is simple: to share knowledge, exchange experiences, and enjoy time together as a community of geophysicists. We hope to see you there!

  Warm regards,
  Geophysical Society of Tulsa Council

  GST Lunch & Learn – December 11 with Guest Speaker

  Dear GST Members,

  Please join us for our next Geophysical Society of Tulsa Lunch & Learn.

  When: Thursday, December 11, 2025
  Time: 11:30 AM – 1:00 PM
  Where: Baxter’s Interurban Grill (main dining area)

  We’re wrapping up the year with something a little different — a guest speaker! 
  

  ABSTRACT:

  The Distance and Quadrant trace: A new family of high-definition, AVO

  attributes for seismic exploration and reservoir characterization. The DQ trace is an AVO, layer-based display of relative porosity, pseudo-well logs. It is a preconditioning step to an AVO quantitative petrophysical inversion for pseudo-porosity/HPV. The DQ family of twelve 3D seismic cubes was first created

  in 2023 and is today being actively developed by the Oklahoma University AASPI

  Consortium. This talk will summarize the theory and workflow used in creating the DQ attributes. Examples of it’s novel high-definition displays taken from both

  carbonates and clastic oil sands of the Volve field, offshore Norway will also be

  shown.

  SPEAKER BIO:

  Dennis Neff retired from Phillips Petroleum Company in 2002 after a 25 year

  career during which he was granted 25 U.S. and International patents involving

  seismic processing, seismic imaging, seismic interpretation, reservoir analysis and

  3D visualization. His work was extensively published in professional journals and

  he received a number of internal and external awards including a SEG Best Paper

  Award, a Computer Graphics Innovation Award, and the company’s prestigious

  Innovation Excellence Award. He also served as a Distinguished Lecturer for the

  Society of Petroleum Engineers and is a Distinguished Alumni of Emporia State

  University were he received a Bachelors and Masters degree.
