Petroleum Geo-Services ASA: PGS and TGS Joint Venture MultiClient Project in the Barents Sea





May 29, 2018; Oslo, Norway, PGS will in late May 2018, start acquisition of a
large 3D GeoStreamer® survey in the Barents Sea in partnership with TGS. The
project will cover ~6,100 sq. km in an active APA area of the Hammerfest Basin
and is due to be completed in September 2018. Fast-track data will be available
in Q1 2019 with final data in Q4.


This project is designed to improve the imaging of the known fields and
discoveries, and allow identification and development of new targets in both
mature and new plays. The survey area contains shallow targets on the basin
flanks and platforms, with deeper exploration potential elsewhere in the basin.

The Hammerfest Basin dataset further expands PGS' MultiClient GeoStreamer
coverage in the Barents Sea, applying true broadband technology to reveal the
full potential of the area. The Hammerfest Basin is already producing
hydrocarbons and is highly relevant for further exploration in the current and
upcoming APA rounds.

The project configuration employs an intelligent towing scheme to maximize
resolution.  Ramform Atlas will deploy an ultra-high-density 3D configuration
with a 16 x 56.25 m x 7000 m setup with a hyperbolic front end. Three of the
streamers are towed with 10 km offsets for optimized performance of full
waveform inversion (FWI). This is combined with a triple source.

The acquisition design is tailored to fully utilize the potential of an advanced
Pre-Stack Depth Migration (PSDM) and FWI processing workflow. Reliable
GeoStreamer data attributes also offer significant advantages for quantitative
inversion (QI).

"In addition to providing an excellent basis for exploration decisions, this new
Hammerfest dataset can be used as a baseline survey for future 4D comparisons,
making this a cost-effective solution for exploration, evaluation, field
development and production monitoring," said Rune O. Pedersen, President & CEO
of PGS.

This is PGS' tenth consecutive year of safe and reliable GeoStreamer acquisition
in Northern Europe.
