We introduce a 3D inversion methodology for towed streamer EM data that takes into account anisotropy and includes a moving sensitivity domain. Our implementation is based on 3D IE method for...

An innovative 3D towed streamer project in offshore Gabon used a dual-vessel continuous long offset streamer configuration to acquire 0-12 km offsets with ten dual-sensor streamers. Streamer control...

Lundin Malaysia BV completed the first-ever application of separated wavefield PSDM imaging to 3D dual-sensor streamer seismic data as a test to improve shallow geological interpretation. The...

The seismic industry is constantly seeking ways of improving the contribution of seismic data to the upstream E&P workflow from seismic acquisition to reservoir modeling. We review recent...

Sea surface reflection coefficient estimates are obtained from imaged sea surfaces by applying an imaging technique that is based on decomposed wavefields acquired by dual-sensor towed streamers. The...

This paper considers data acquired with the newly developed Towed Streamer EM System over The Troll West Oil Province in October 2012. We study how the uncertainties within the data propagate into...

Reverse-time migration applied to shot gathers, has typically outputs stacked images. This does not allow for the use of the multi-dimensionality of the data after imaging. For todays wide- and...

In this paper, a method is presented to compute 3D surface-related multiples using multi-component sensor data that have been acquired with streamers at variable depth. An equivalent for single...

We apply 3D vertical transversely isotropic (VTI) full-waveform inversion (FWI) to a towed-streamer dataset acquired in shallow water in the North Sea, offshore of Norway. We show that FWI yields a...

The first regionally extensive long offset 2D seismic program has been acquired in the slope and deepwater regions of the Labrador Sea, offshore Canada. The survey was planned integrating well ties...
