NORTH VIKING GRABEN - LOCATION MAP
INTRODUCTION
TGS, in partnership with Petroleum Geo-Services (PGS), has recently
completed its third year of acquisition in the Viking Graben. The total
area acquired over this period is in excess of 7,300 km2
of 3D data in
this prolific hydrocarbon area. This allows for a regional overview of
prospectivity and new exploration opportunities.
The principal advantage of Geostreamer®
is the ability to deliver
broader bandwidth and improved signal to noise ratio without
compromise. The unique co-location of pressure and particle velocity
sensors enables the separation of the upcoming and downgoing
wavefields. The sea-surface reflection is removed along with the
effects of the undesirable notches it produces in the signal bandwidth.
Geostreamer®
is therefore towed deeper, in an operationally
more efficient and quieter environment, improving low frequency
penetration and without compromising bandwidth.
GEOLOGY
The exploration history within the NVG surveys spans early
discoveries through to recent exploration success. Examples include:
ƒƒ Heimdal, discovered in 1972, with hydrocarbon reservoired in
Palaeocene sediments as an early exploration success on the
Norwegian shelf
ƒƒ Peik gas condensate field, discovered in 1985, with hydrocarbon
reservoired in the Jurassic Hugin Formation in the western portion
of the survey
ƒƒ Alvheim a Palaeocene Heimdal formation oil field, discovered in
1998 and covered by the NVG survey
Considerable exploration potential remains at numerous stratigraphic
levels within the greater NVG survey areas, a conclusion supported by
recent exploration drilling success.
