Watch TechByte Webinars on 4D Seismic

May 4, 2021

TechByte webinars explain imaging and operations topics in simple terms in ca. 15 minutes. The latest series of webinars by PGS Chief Geoscientist Andrew Long addresses 4D seismic issues of repeatability, detectability, and managing uncertainty.

The material is available via our webinar library.

  • How repeatable is towed-streamer 4D seismic? Part one addresses the geometry of how we acquire 4D surveys, and how well the source and receiver positions can be repeated.
  • What is 4D detectability? In part two, Andrew Long reviews goals and challenges to our ability to detect subtle 4D signals.
  • How can we manage 4D reservoir property uncertainty? Finally, given the uncertainty in the 4D signals, how we might interpret the results?
