A mapping of Tubaen Fm based on the ST0306 survey was reported in Hoyen (2006). A depth map of the greater
Snohyit / Albatross area is shown in Figurę 1 5, and a morę detailed map around the 7121 /4-F-2 H well is shown
in Figurę 16. mapped several intra-Tubaen reflections based on increased resolution seismic. The
Top Tubaen reflection onlaps the Intra Tubaen reflector eastwards. The thickness of Tubaen Fm increases
westwards, the thickness variations are smali in the F-segment however. Total Tubaen Fm thickness in F-segment
is 45-55 ms. An amplitudę map of the base Tubaen / top Fruholmen reflection is shown in Figurę 1 7, indicating
the variation in reflectivity at Top Fruholmen. Also the Iow amplitudę areas caused by gas in the shallower
sediments east and west of Snohvit F-2 H CO/ injector are indicated by red circles.
