LAS VEGAS – CGGVeritas chose the 2012 annual meeting of the Society of Exploration Geophysicists to reveal the preliminary examples of data from its IBALT multi-client Gulf of Mexico full-azimuth StagSeis seismic survey.
StagSeis is a new system that uses staggered multi-vessel acquisition to get long offsets to 20 km (12 mi) and full-azimuth coverage to 10 km (6 mi).
This approach results in improved illumination, multiple attenuation, signal-to-noise ratio, and velocity modeling, said CGGVeritas, to get better results subsalt and sub-basalt.
The system uses not only the novel acquisition design, but also benefits from BroadSeis streamer depth control and CGGVeritas’ processing programs.
The IBALT program is ongoing and should be completed late this year or early 2013.
