The GATHERing Americas 2023 is over 

We look forward to seeing you again next year!

The GATHERing Americas 2023!

The Gathering, Sharp Reflections’ user group meeting, is a unique opportunity to meet and exchange experiences with other PreStack Pro users, learn from the Sharp Reflections experts and industry colleagues, get hands-on training and discover the benefits of the latest PreStack Pro release 6.6 and 6.8.

We are looking forward to exciting discussions about today’s solution and collaborations for the future. We hope you can join us.

See you there!

The Sharp Reflections Gathering team


Date: March 1-2, 2023


Location: Tremont House, Galveston, TX (Discounted hotel rate is available.)


Early bird: $299 (by Jan 31)
Standard fee: $350

Fun all around



GATHERing Americas 2023 took place March 1-2 in Galveston, Texas, USA. 


We learned. We laughed. We discussed the future. And we wished you were there! See you next year.

Don’t just take our word for it


“I really enjoyed the overall format.  The mix of talks and hands-on was ideal. Wouldn’t change it.”


“The tutorial is great. Very eye-opening to see what the software can do.”


“The user talks and hands-on exercises – I learned a lot from both!”

Hands-on training session topics

Whether you’re a new PreStack Pro user, a veteran or just want to get a refresher, you will have the opportunity to select from the below topics for your hands-on training sessions.


Topic 1: Overview of PreStack Pro functionality and quick, interactive AVO techniques

  • Visualization of seismic data
  • Data quality assurance (QA)
  • Offset-to angle conversion
  • Amplitude, intercept, gradient maps
  • Surgical cross-plotting
  • Chi scans
  • On-the-fly spectral decomposition
  • Running workflows

Topic 2: Data enhancement for QI

  • Residual multiples
  • Coherent and random noise
  • Event misalignment

Topic 3: Geophysical inversion to geology – asking geological questions to drive exploration and discovery

  • Relative AI and Vp/Vs inversion
  • Investigate simple Litho-Fluid Class (LFC) prior models
  • Infer reservoir horizons from inversion

Topic 4: Multi-azimuth seismic analysis

  • Visualizing multi-azimuth data
  • Create 5D attribute extractions
  • Extend post-stack horizons to 5D pre-stack horizons
  • Perform selective stacking, Amplitude vs. Azimuth (AVAz) analysis, and more

Topic 5: Efficient 4D seismic data analysis

  • Model effects of different fluids in the reservoir
  • Make use of multi-vintage data object and on-the-fly difference-in-viewer tools
