PGS and TGS Ramp Up 3D Activity Offshore Eastern Canada

May 23, 2017: OSLO, NORWAY- Petroleum Geo-Services ASA ("PGS" or "the Company")
and TGS announce two new MultiClient 3D seismic projects offshore Eastern
Canada. Following on from the recently announced 2017 2D seismic campaign and
the Cape Broyle 3D, the joint venture is now ramping up its 3D seismic
acquisition in Newfoundland Labrador with these additional projects, reflecting
high customer interest in this region.


East Flemish Pass 3D Phase II is a 1,950 square kilometers extension of a 3D
survey that was acquired by the joint venture in 2016 in the Eastern
Newfoundland region.  The survey will extend eastwards into block EL1150, which
is expected to see drilling activity in the future.

Harbour Deep 3D will comprise a minimum of 2,700 square kilometers of 3D
GeoStreamer data in the Eastern Newfoundland region covering a mix of held and
open acreage to be included in the November 2018 licensing round under
Newfoundland Labrador's Scheduled Land Tenure system.

Following completion of these surveys the jointly-owned library will have more
than 175,000 line kilometers of 2D GeoStreamer data and 19,400 square kilometers
of 3D GeoStreamer data. An expansive well log library is also available in the
region, along with advanced MultiClient interpretation products that will
improve play, trend and prospect delineation.

"Our growing MultiClient data library benefits the oil companies exploring this
high potential area, and makes us well positioned for upcoming license rounds.
This will be our most active season in the Newfoundland Labrador region to date,
reflecting high customer interest," says Jon Erik Reinhardsen, President & CEO
of PGS.

"Newfoundland Labrador continues to attract high interest from E&P companies.
We have built significant geological and operational experience in this region
over many years which, combined with the leading multi-client data library,
positions us well to support E&P companies in their drilling and exploration
activities," commented Kristian Johansen, CEO of TGS.


These projects are supported by industry funding.
