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:

� Heimdal, discovered in 1972, with hydrocarbon reservoired in Palaeocene sediments as an early exploration success on the Norwegian shelf

� Peik gas condensate field, discovered in 1985, with hydrocarbon reservoired in the Jurassic Hugin Formation in the western portion of the survey

� 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.
