PGS : Acquisition Complete on GeoStreamer X Viking Graben 2020

The GeoStreamer X Viking Graben 2020 extension project once again applied PGS's latest technology innovations for advanced offset- and azimuth-rich data. The project builds on the successful 2019 GeoStreamer X pilot project in the same area.

'The Ramform Vanguard managed its dense streamer spread in combination with record-wide sources, acquiring a survey that will deliver a dataset of excellent quality, with high resolution, optimal near-offset distribution for shallow imaging, improved demultiple, and AVO. The Norwegian exploration industry needs improved data quality in this area, to address a number of challenges. PGS has addressed this with a novel and efficient multi-azimuth towed-streamer solution and bespoke imaging workflow,' says Gunhild Myhr, VP New Ventures at PGS.

GeoStreamer X solves known illumination challenges on the Viking Graben associated with sand injectites, such as injectites cemented with anomalously high velocities (so-called 'v-brights'), and injectites with reservoir potential that definitely require better illumination.

On this year's Viking Graben survey the ultra-near offsets were achieved with the wide-tow sources yet, achieving a record of 250 m between outer sources. This efficient solution is the widest ever towed from a single vessel.

The dense streamer spread included several long streamer tails that will provide the needed offset for optimal FWI at depth. Early-out data will be ready in Q4 and final depth imaging data will be available Q2 2021.
