The simultaneous firing of marine sources can provide a significant uplift in terms of acquisition efficiency and data quality enhancement. However, the seismic interference resulting from one or more ‘other’ sources needs to be well understood a

The launch of the dual-sensor towed streamer technology in 2007 is seen by many in the industry as the most important milestone in marine seismic technology in the last decade. The introduction of the technology triggered a significant interest and d

SUMMARY In practice, acquisition and processing solutions to poor seismic illumination begin with an effort to compensate for gross holes in the density of target illumination using conventional Narrow-Azimuth streamer acquisition. As the complexity

In seismic exploration, there is continuous drive towards more dense data sampling to better image complex geological structures. Recent advances in acquisition such as Wide-Azimuth, Multi-Azimuth or Rich-Azimuth acquisition can deliver a more divers

The use of collocated pressure and motion sensors allows the separation of the up- and down-going waves and thereby removal of the receiver ghost. Having access to the up- and down-going wavefields yields significant benefits for seismic data process

Abstract High quality sub-salt imaging has remained a challenge for the seismic industry over the last two decades. Recent modeling and case histories have demonstrated that increased cross-line offset improves the image quality significantly: illumi

Summary Dual sensor streamer effectively removes the receiver ghost from seismic data through dual sensor summation. By doing so, one achieves preservation of a broader seismic bandwidth. In particular, low frequencies are significantly enhanced whic

In 2009, two dual-sensor streamer 2D seismic surveys were conducted offshore China under a common geological research project. The first survey was in Nanhuanghai (South Yellow Sea, Figure 1) with water depth varying between 60 and 80 meters. The sec

This paper discusses a simultaneous source wide azimuth acquisition experiment which was performed in the Gulf of Mexico. Out of a total of 4 sources, two of them were fired simultaneously, with all firing times being randomized within a small window
