ABSTRACT

Ocean bottom node (OBN) acquisitions provide the increased illumination necessary for imaging deep targets below complex overburdens. In such cases, internal multiples can also be detrimental to the image at the target level. Following the concept of "overburden/target separation" for internal multiple attenuation (IMA) introduced by van der Neut and Wapenaar (2016), we extend the formulation to be applicable to ocean bottom recordings. We demonstrate the results for up-going and down-going wavefields on a data set from the Santos Basin, offshore Brazil, where internal multiple contamination is a widely recognized imaging problem.
