PGS in partnership with Agncia Nacional de Petruleo, Gas e Biocobustive is (ANPG) has recently acquired 8,304 sq. km of new multisensor GeoStreamer data over the Kwanza Shelf, 30 km off the central...

Held in Amsterdam on October 17-22, the annual EAGE conference provided a particularly interesting industry forum as the world moves into a lower carbon future. Carbon Capture and Storage (CCS)...

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,...
