Dolphin Geophysical started mobilization for two new multi-client 3D projects in the Barents Sea off Norway using the newly launched, high-capacity 3D seismic vessel, Sanco Sword.
The Gohta North and Maud Basin South 3D surveys, covering about 6200sq km, will be acquired using SHarp Broadband acquisition and processing techniques.
The SHarp Broadband technique also allows high-end, fast-track data volumes to be delivered within four weeks of finishing acquisition.
“These data volumes are crucial for these Barents Sea projects as it will allow early participating companies to rapidly screen and technically evaluate the prospectivity of the acreage in the 23rd and APA 2014 Rounds,” says Dolphin.
The Sanco Sword will be deploying as many as 12 streamers, with 75m separation and 7km offsets, depending on varying geological targets within the respective survey areas, ranging from Jurassic to Permian carbonate plays.
The vessel is on an initial 5-year time-charter agreement from Norwegian vessel owner Sanco Shipping.
The Sanco Sword is the sister vessel of the Sanco Swift and both were delivered from the Kleven Myklebust yard, on Norway’s west coast. Both vessels are 96m-long and capable of towing record spreads of up to 16 streamers at 100m separation.
