Spectrum, Sovcomflot start Barents seismic campaign

Written by  OE Staff Wednesday, 12 July 2017 03:43

Geoscience firm Spectrum has started the acquisition of a new seismic survey in the Barents Sea as part of the ongoing Norwegian 24th licensing round.

The new Norsel High 3D acquisition comprises a minimum of 1600sq km, covering four blocks that are included in the round.

Data is being acquired by survey partner Sovcomflot (SCF), using its modern high capacity vessel Ivan Gubkin with a triple source configuration and a Q-marine acquisition system. Utilizing these latest acquisition technologies combined with broadband processing will ensure optimal imaging of several large structural closures at the Jurassic and Triassic levels partially identified in the area from existing Spectrum data.  

The program further includes 3D broadband reprocessing of 2000sq km of neighboring 3D Spectrum data that cover an additional 6 blocks included in the  24th licensing round. Merging the newly acquired survey with the existing two datasets through a modern broadband processing sequence will result in a single contiguous, conformable dataset of 3600sq km covering 10 prospective blocks. 

A high quality Fast-track 3D volume will be created for delivery before the end of August 2017 allowing sufficient time for evaluation of the area prior to the application deadline of the round on November 30th. Further interim Pre-Stack Time Migrated data will be made available in time for application revision prior to November. Pre-Stack Depth Migration will be optional following round block award.
