Find out how PGS can solve your 4D challenges and provide tailor-made solutions to enable you to extract more, optimize your assets and enhance production. (PGS 2021)

How repeatable is towed-streamer 4D seismic? In the first of three webinars on 4D, Andrew Long addresses the geometry of how we acquire 4D surveys, and how well the source and receiver positions can be repeated. (PGS 2021)

What is 4D detectability? In the second of a three-part series on towed-streamer 4D seismic, Andrew Long reviews the goals and some key challenges to our ability to detect subtle 4D seismic signals. (PGS 2021)

How can we manage 4D reservoir property uncertainty? In the third of a three-part series on 4D seismic, Andrew Long acknowledges the uncertainty in the 4D signals and explores how we might interpret the results. (PGS 2021)
