French seismic firm CGG has launched a western extension of the Horda BroadSeisTM-BroadSourceTM 3D multi-client program it began acquiring in the Northern North Sea offshore Norway in 2014.
The extension, known as Tampen, is in the Northern Viking Graben offshore Norway and the UK and is expected to be completed in 2016. It will add a further 17,000sq km of data to the initial 18,000sq km Horda survey that CGG will complete this season to provide a total of 35,000sq km of contiguous and uniform broadband seismic data coverage.
The Tampen survey will cover a mature, high-potential area encompassing fields such as Statfjord, Gullfaks, Snorre and Osberg in Norway in addition to several fields in the UK.
"The overall Horda multi-client program will offer an integrated geoscience package to support exploration and development activities," says CGG. "It will include geological context and a prospectivity review, potential fields data, satellite hydrocarbon seep imagery, a high-quality well database, biostratigraphy, sedimentology and geochemistry data, and seismic reservoir characterization products supported by reservoir-quality seismic data."
Both the fast-track and full imaging of the Horda program is being undertaken in Norway with CGG’s latest broadband subsurface imaging technologies. Fast-track data from the 2014 8500sq km section of the initial Horda survey was delivered in Autumn 2014, only 10 weeks after completion of the acquisition.
The final data for this area as well as fast-track data for both the full 18,000sq km Horda survey and this season’s section of the Tampen survey will be available in Q4 2015.
Jean-Georges Malcor, CEO, CGG, said: “Our first Horda survey received such strong industry support from key industry players in the Northern North Sea, we decided to expand the model to the Tampen area. We believe the overall program represents the future of multi-client seismic surveys in Norway and offers clients an extensive, detailed, integrated and cost-effective dataset in a very prospective oil province offshore Norway. The Horda and Tampen surveys will allow them to calibrate and compare the seismic response from existing discoveries and new prospects and leads. This will reduce the risk of drilling structures adjacent to old discoveries and develop new play models in the region."
