PGS is reprocessing ca. 8 000 sq. km of 3D data West of Shetland. This region has seen major exploration successes but also challenges related to subsurface structure and stratigraphy. Fully migrated 3D data will provide an improved and consistent regional geological perspective. The results will be ready in January 2022.
The 2021 PGS MegaSurveyPlus rejuvenation project targets data covering ca 8 000 sq. km west of Shetland, including GeoStreamer multisensor data acquired in 2013 and 2015. The GeoStreamer component adds content with a very high signal-to-noise ratio and a broad bandwidth into a data mix of various vintages. PGS has an excellent track record in this type of broadband reprocessing using the latest imaging workflows.
“New broadband reprocessing of a largely conventional dataset will help to confidently risk upcoming projects West of Shetlands. Advances in processing and imaging techniques, combined with increased compute power, mean that we can extract more details from the data, improve velocity models, and deliver more reliable and detailed images that will improve sub- and post-basalt imaging in general and sub-basalt assessment in particular,” comments Christopher Schou Watts, VP Sales & Services at PGS.
