On March 1, a presentation on "A Robust Broadband Deghosting Procedure for High Resolution Outcomes" will be available online as part of the 2016 Virtual Lecture Series. This presentation by Gaby Yelin, Application Geoscientist at Paradigm, will present the Paradigm Deghosting solution, explain the methodology, and compare the results to different acquisition techniques. The presentation is approximately 19 minutes long.
Whenever a source and receiver are positioned below a strong velocity contrast, ghost reflections are generated. This is manifested as notches in the frequency domain and loss of low frequencies.
The reflection ghost problem has been known since the early days of marine acquisition. In spite of many advances in technology and acquisition configurations aimed at improving the frequency spectrum which deteriorates due to the presence of ghost reflections, the low resolution component of the spectrum is still missing. In recent years this topic has become of major interest due to FWI, where recovering low frequencies is crucial.
We encourage you and your colleagues to register today!
Upcoming 2016 Virtual Lecture Series sessions in March include:
- March 15: Interpretation Validation
- March 29: Comprehensive Seismic Analysis and Interpretation with Prestack Data
