Abstract
BP has developed seismic acquisition technologies like DS3, ISS® and ISSN™ which have efficiently delivered azimuthally rich and dense high quality seismic data, in desert terrains originally and subsequently in marine environments, with no detrimental effect on data quality. The source de-blending processing capability was initially based on source randomization and noise attenuation techniques. Since the implementation of these technologies from 2007, the state of deblending in the market has progressed. We have recently evaluated the ISS® deblending capability in seismic processing from four different processing vendor technologies on the same pseudo-blended OBC data from an Indonesian shallow water environment. The assessment was performed using a new similarity metric NCC2D based on cross-correlation, along with the standard repeatability measurements NRMS and SDR. While there remains a range in the quality of deblending results, all contractors involved in this exercise delivered reasonable and acceptable products.
