The combined Horda, Tampen and NVG South extension BroadSeis™ – BroadSource™ surveys deliver 44,000 km2 of consistent 6-octave full-bandwidth data in the northern North Sea.
PSTM data from NE Horda with interpreted basement surface
The Horda and Tampen surveys cover mature exploration areas such as; the Northern Viking Graben, Tampen Spur, Horda Platform and the Sogn Graben. To date more than 40 BBOE have been discovered in the region, in the giant discoveries such as Statfjord, Gullfaks, Oseberg, Troll and a number of other fields. Many small to medium sized discoveries have been made the recent years, including Brasse, Duva (Cara) and Rungne
More importantly, this still represents only a small fraction of the oil believed to have been generated, and therefore huge remaining reserves are likely. This consistent, regional broadband dataset will be the baseline for further activity in the region for years to come, through all phases, from exploration through to development and production.The new NVG South extension covers the area from the Horda/Tampen survey southwards over the eastern parts of the Utsira High and the south-western part of the Stord Basin, the Patch Bank Ridge and parts of the Ling depression. The Utsira High is an area with several large discoveries such as Johan Sverdrup, Edvard Grieg, Balder and Ringhorne. The Stord Basin is an underexplored area, where presence of mature source rocks has been regarded to be a main risk. CGG’s shallow coring geochemical study from 2016 identified hydrocarbon leakages, of both gas and oil character, indicating presence of local, mature source(s). An increased industry interest resulted in four new license awards within the NVG South area in the 2018 APA round.
This unique BroadSeis - BroadSource dataset combines long offsets, a dense streamer configuration and our state-of-the-art subsurface imaging technology to provide the clearest and highest-resolution images available in this complex region.
A JumpStart integrated geoscience package can be delivered, including geological context, well data, a prospectivity review and seismic reservoir characterization, all in addition to reservoir-quality seismic data.
101 wells have been analyzed and calibrated to the Horda/Tampen seismic dataset and are available now. The Horda/Tampen PSTM and PSDM data is available now.13 additional wells in the NVG South area will be available in October 2019. NVG South fast track PSDM is available now, final PSDM will be available by December 2019.
