Machine learning, and the variations thereof, have been around for a considerable time, perhaps as far back as the early 19th century with Bayes work on probability theory. It is then a bit of a...

Imaging the subsurface using passive data acquired with a towed streamer configuration is discussed in this paper. Instead of an active source, the acoustic wavefield generated by the seismic vessel...

Seismic images are often contaminated by migration noise. The noise attenuation process can take a lot of effort from the domain expert and, in many cases, it can be challenging to get the optimal...

Extracting the most reliable, high quality elastic and reservoir properties from seismic in an effective manner has always been the quest for every geoscientist trying to build a reservoir model or...

We introduce an inversion approach to simultaneously invert for both velocity and reflectivity. The core of the inversion workflow is a novel wave-equation that provides the full acoustic wavefield,...

We describe a series of barnacle mitigation measures applied during a five-month towed-streamer seismic survey by the Ramform Titan in the Campos Basin, Brazil. The 14 x 10000m streamer spread was an...

An ultra-wide penta source configuration was deployed in combination with a high-density multisensor streamer spread to address shallow exploration targets in the western part of the Norwegian...

The automation of model building using Full Waveform Inversion (FWI) depends on the lowest frequencies available in the data and an accurate initial model to avoid cycle skipping. To overcome the...

A large-scale three-year experiment recently quantified the impacts of exposure to a commercial seismic source on an assemblage of tropical demersal fishes targeted by commercial fisheries on the...
