SWNR13M 3D

Enhanced data in the Hammerfest Basin
Website Map for Survey MC3D-SWNR13M
The reprocessed conventional dataset covers the Hammerfest Basin and the southern flank of the Loppa High highlighting structures and reservoirs more accurately for better evaluation of the area.
The data provide coverage over the northeastern part of the Snøhvit Field and the Beta discovery. Exploration in the Hammerfest Basin has proven several petroleum systems and plays with the presence of multiple source rocks of mainly Jurassic and Triassic age.
Reprocessing included comprehensive de-noise and de-multiple flow including 3D SRME. The survey is available in both time and depth.
