oa A client’s perspective of recent learnings and improvements from a 3D survey using highly sampled 3C marine streamers

A multimeasurement streamer system was used to acquire data for generating a volume with improved resolution and signal-to-noise ratio (SNR) relative to legacy data. The initial data preconditioning flow did not result in the desired uplift in SNR in the 3D/3C receiver-deghosted, wavefield reconstructed product. We illustrate different and new types of noise observed and discuss the mitigation approach and implications for both on-board and shore-based data conditioning. We demonstrate the significant uplift observed in the 3D/3C deghosted and wavefield reconstructed product resulting from extensive testing and additional data preconditioning steps.
