We present an iterative non-linear inversion method to simultaneously estimate both velocity and reflectivity. The core of the inversion workflow is a full acoustic wavefield modeling relation...

Depth imaging in complex geology requires an accurate background model. In this case study, over the Clair field, we make use of high density node data set and Full Waveform Inversion (FWI) with...

Reliable seismic amplitudes are crucial for the estimation of rock properties. In conventional depth imaging, amplitudes and resolution will be influenced by propagation effects in the imaging model....

The Sleipner natural gas field situated in the Norwegian sector of the North Sea is the worlds longest-running industrial-scale CO2 storage project. The CO2 injection commenced in 1996, inserting...

In this paper, we will demonstrate how a novel marine multi-azimuth acquisition solution enabled better illumination below and within complex velocity structures like sand injectites, chalk and...

The acoustic wavefield originating from the seismic vessel itself is generally not treated as acoustic signals in the imaging of marine seismic data, and is typically categorized as ambient noise. If...

The abstract describes a methodology to compute time-varying, depth-dependent water column interval velocity profiles from Ocean bottom seismic data. The objective is to use these profiles to correct...

The ability to estimate a mixed phase wavelet is a useful tool for processing and quality control in seismic imaging. The wavelet is estimated using higher order statistics of the data. In practice,...

This paper presents a case study of a 3D marine streamer seismic acquisition using an ultra-wide-tow penta source set-up to improve trace density and near offset coverage without compromising...

Overcoming cycle-skipping in Full Waveform Inversion (FWI) is a significant step toward enabling automation in velocity model building. This reduces the demand of acquiring very low-frequency data...

This paper will focus on the reservoir characterization / quantitative seismic interpretation of a recently acquired and processed multi-azimuth multi-sensor survey in the prolific South Viking...

The SEG Advances in Marine Seismic Data Acquisition Workshop was held virtually on September 7-9, attracting about 80 registered participants. 24 presentations were spread over three half-day...

The authors look at the reservoir characterization of a recently acquired and processed multi-azimuth multisensor survey in the prolific South Viking Graben, offshore Norway.
