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:

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
