PGS has recently completed deployment of the worlds first, and to this date only, full-solution deep-water PRM project in the Jubarte field in Brazil for Petrobras. The project includes a fully...

In October 2012 the Alvheim-Boa Field was surveyed as part of a North Sea acquisition campaign with the newly developed Towed Streamer EM System to provide resistivity estimates over a number of...

Conventional wave equation migration extrapolates upcoming boundary data generated from primary reflections to image the subsurface. In marine seismic data processing, sea surface related multiples...

This paper describes a new method for on-line evaluation and acceptance of seismic interference (SI). The project was split into three phases. The first phase utilized existing data with SI issues...

This paper describes how a large, 12,030 sq.km, exploration 3D seismic survey in the Great Australian Bight was designed in order to maximize the efficiency of the survey. The entire survey area was...

3D angle domain common image gathers (ADCIGs) from reverse time migration (RTM) provide accurate representation of residual moveout in complex media, especially in the presence of salt. Thus,...

Reflection tomography is non-unique and a regularization term is usually added into its objective function as an additional constraint. The anisotropic Gaussian filter has been successfully employed...

Reverse time migration (RTM) imaging can have significant artifacts which are generated by back scattered and turning waves, where the source and receiver wavefields are in phase. This paper gives a...

Viscoacoustic imaging in anisotropic media is achieved by tomographic estimation of the earth attenuation (Q model), and prestack wave equation migration. The proposed Q tomography algorithm uses...

The current approach for the quality control (QC) process of the swell noise filtering phase carries significant drawbacks. This abstract investigates the use of statistical techniques to improve the...
