ABSTRACT

This paper presents acquisition and processing results from a 3D streamer acquisition trial of triple-source apparition data, with an emphasis on processing.

We show that, after apparition de-blending, initial migration results did not show resolution improvements over a reference unblended dual-source dataset. However, attentive 3D processing of the same de-blended data gave substantial improvements to image resolution.

Time slices from the fully processed apparition data show higher resolution than the corresponding reference data.
