Petroleum Geo-Services ASA : Settlement of patent disputes between PGS and EMGS

April 13, 2016: Oslo, Norway, Petroleum Geo-Services ASA ('PGS' or the

'Company') announces that PGS and Electromagnetic Geoservices ("EMGS") have

entered into a Settlement Agreement settling their patent disputes.

On December 16, 2013 EMGS filed a complaint in the United Kingdom against PGS in

the High Court of Justice, Chancery Division, Patents Court. The complaint

alleges that the PGS Defendants had infringed EMGS's European patent EP 1256019

("Refracted Wave Patent"). EMGS also initiated a parallel proceeding before Oslo

City Court in Norway on April 4, 2014 relating to PGS' Towed Streamer EM

technology for infringement of EMGS's parallel Norwegian patent, NO 324 454 (the

"EMGS Patent").

On March 5, 2015, PGS EM Limited filed a complaint in the U.S. District Court

for the District of Delaware against EMGS. This complaint alleges that the EMGS

Defendants have, at least by their survey activities in the Gulf of Mexico and

on the U.S. outer continental shelf and by their interactions with U.S.

customers and their importation of certain data products into the U.S.,

infringed PGS-owned U.S. patent 6,914,433, titled "Detection of Subsurface

Resistivity Contrasts with Application to Location of Fluids".

The above disputes have all been settled by the Settlement Agreement. The

Settlement Agreement grants PGS a license to the EMGS patent for operation of

its Towed Streamer EM system. EMGS is similarly granted a license to the PGS

patent. Both licenses are royalty free and valid world-wide for the validity

period of the relevant patent.

The Settlement Agreement also opens up for joint EM and seismic surveys in the

future.

Both EMGS and PGS support the validity of both the EMGS Patent and the PGS

Patent.

Both companies will cover their own legal costs.
