Abstract
P33 NJORD MULTI AZIMUTH MULTI VINTAGE STACK DEPTH MIGRATION FOR IMPROVED IMAGE OF STRUCTURE AND RESERVOIR – A CASE HISTORY FROM OFFSHORE NORWAY Summary 1 A multi azimuth and multi vintage pre-stack depth migration (PreSDM) study conducted in the NJORD field offshore Norway significantly improved the image quality in the area of the reservoir over the existing post- and pre-stack time and depth migrations. In this case history we present: ● A description of the existing data sets with different azimuths and vintages in the project area and simulation of a full (multi azimuth) seismic data volume combining limited azimuth
