GATWICK, UK –WesternGeco has introduced ObliQ sliding-notch broadband acquisition and imaging technique to enhance low frequencies in marine seismic data without compromising high-frequency data.
Optimized seismic bandwidth is achieved by combining variable streamer depth acquisition with a proprietary deghosting method and a new broadband seismic source. This proprietary processing is applied early in the sequence, making the data suitable for both time- and depth-domain analysis.
Enabled by the Q-Marine point receiver marine seismic system, ObliQ can also be used with other WesternGeco technologies such as Coil Shooting and Dual-Coil Shooting full-azimuth acquisition to combine broad bandwidth with full-azimuth, long-offset acquisition. This combination is particularly important for imaging below complex structures such as subsalt and sub-basalt, said WesternGeco.
