Seismic data acquired from more than one direction are illuminating structures that standard surveys find hard to image, such as carbonate rocks or laminated sands below salt, and basalt formations. Multi-, wide-, and rich-azimuth techniques result in better signal/noise ratios and natural attenuation of some multiples. Coil Shooting single-vessel full azimuth acquisition geometries take the concept further, recording data from a wide range of directions.
An integrated acquisition and processing technique for illuminating complex structures draws on the capabilities of Q technology to improve drilling success rates and reduce exploration challenges.
- Wide-Azimuth Marine Seismic Acquisition
Seismic surveys that acquire data from more than one azimuth deliver more information about deepwater salt domes and the sediments below them. The ability to record data while turning the vessel makes nonconventional acquisition geometries possible.
- Coil Shooting
Seismic data acquired by streamers from a single vessel moving in circular patterns contain reflection information from the full range of azimuths, accurately imaging sediments beneath hard seafloors and salt, basalt, and carbonate layers.
- DISCover
DISCover deep interpolated streamer coverage is designed to efficiently deliver 3D seismic data with an enhanced bandwidth, providing both high resolution and deep penetration. The basic premise is that a sparse number of deep streamers are towed below a regular array of shallow streamers.
In the ISIS simultaneous inversion method all the available seismic data are gathered at once and inverted for angle-independent quantities. This process ultimately leads to a better model.
