Workshop 16
Marine Vibrators: Good, good, good – Good vibrations? Monday June 10th | Room 4
Convenors
- Peter Hanssen (Equinor)
- Thomas Elboth (Shearwater)
- Rune Tenghamn (Akitemos Solution)
- Enrico Zamboni (TotalEnergies)
Description
In recent years, several projects have developed towed marine vibrators (MV) to meet increased environmental requirements and to secure a license to operate. This first workshop on MVs will look at the history of seismic sources, their technical challenges, and future applications. Recent results from offshore tests and environmental studies will be presented and we will discuss new acquisition designs, signal and pre-processing methods.
Sub-Topics that will be covered in the workshop:
- Marine Vibrator history & outlook
- Marine Vibrator hardware
- Marine Vibrator signal and pre-processing
- Environmental studies
- Acquisition design
- Offshore 3D test results
Participant Profile
Geophysicists interested in seismic acquisition, including instrumentation, signal processing, automation, low frequencies, and efficiency. Engineers who want to learn about different approaches to constructing an offshore vibratory source. Environmentalists, regulators, and managers who want to learn about reduced HSE, impact on fauna, and source parameters beyond SPL and SEL.
