Multi-client seismic data specialist Spectrum has started the acquisition of a new seismic survey of areas available in the ongoing Norwegian 24th licensing round.

Spectrum said on Wednesday that the new Norsel High 3D acquisition comprises of at least 1,600 square kilometers, covering four blocks that are included in the round.

Data is being acquired by survey partner Sovcomflot (SCF) using its high capacity vessel Ivan Gubkin, formerly known as the Polarcus Amani, 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,” said Spectrum.

The company added that the program further includes 3D broadband reprocessing of 2,000 square kilometers of neighboring 3D Spectrum data that cover an additional six 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 3,600 square kilometers covering ten prospective blocks.

According to Spectrum, 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 30.

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.
