Among the various types of converted waves, those involving conversion at both the top and base of the salt—such as PSPP and PPSP modes—are especially problematic due to their strong amplitudes and...

In the last few years, there has been an increased interest for multi-parameter Full Waveform Inversion (MP-FWI) within the seismic industry. This paper revisits the motivation for this approach and...

The integration of sparse OBN acquisition with Elastic Full-Waveform Inversion (EFWI) markedly improves subsalt imaging in the Gulf of Mexico. This combined approach offers accurate salt geometry...

The low-frequency sources developed in the last two decades such as Wolfspar® (Dellinger et al., 2016) and the Tuned Pulse Source (TPS) (Ronen and Chelminski, 2017), have been designed to provide...

The recent Nefertari gas discovery in the Western Mediterranean offshore Egypt, has proved the potentiality of the area for hydrocarbon exploration; however, exploration remains challenging due to...

This abstract covers the application of 4D full waveform inversion (FWI) on an Ultra High Density Ocean Bottom Node dataset. The node count was over 25,000 for the project, which is an incredibly...

How Technical Asset Management Platforms Are Enabling the Hybrid Transition As hybrid solar and battery projects become the new standard, operators are facing rising complexity and tighter margins....
