CORNERSTONE
OBN
Cameron Grant
A step-change in CNS imaging
Developed in conjunction with Magseis Fairfield, the multi-phase multi-client Cornerstone
OBN program will deliver subsurface images of unprecedented quality in the most challenging
areas of the UK Central North Sea (CNS).
Phase I began in March 2020 and will provide approximately 2,500 sq. km of full-azimuth data
for HP-HT areas where salt diapirism creates challenges for seismic imaging using existing
long-offset streamer data.
First results are expected in Q1 2021.
The right data, in the right place, at the right time
