... geometry, meant that the area was covered four times by the source carpet, which helped improve the signal-to-noise ratio. Aggressive noise attenuation was still required to attenuate the high-energy near-field source direct arrival in the active NFHs, which could only be used for the very shallow imaging...

In this paper we detail recent advances to this workflow, leading to enhanced imaging results from offshore Abu Dhabi. Amundsen (2001) showed that deconvolving the up-going wavefield by the down-going...

... noise attenuation have been key to provide the desired level of Signal-to-Noise ratio and achieve high vertical resolution. The project is also part of a broader work that aims to cover the Abu Dhabi Emirate with high-density surface seismic. Hence, the survey was designed and processed to deliver...

... alone, as PZ summation does not remove the free surface multiples. Subsequently, 1D deconvolution was applied in the vintage processing to attenuate receiver-side pegleg multiples. The pairing of the PZ summation with de-pegleg reduced receiver-side multiples in the data. Nevertheless, the overburden...
