Electromagnetic  Geoservices  ASA  (EMGS),   the  market  leader   in
electromagnetic  (EM)   imaging,  today   reported  that,   following
proceedings launched by Schlumberger, three  of its patents were  not
upheld in a first instance decision at the High Court in London. EMGS
retains over 115  patents in 32  jurisdictions and in  excess of  130
applications in 26 jurisdictions around the world.

In addition, EMGS and Warburg  Pincus LLC today jointly announce  the
appointment of Goldman  Sachs to  conduct a review  of the  strategic
options available  to EMGS  in the  future commercialisation  of  its
business.

Bjarte Bruheim, Chairman of EMGS, commented:

"Following today's decision, which is open to appeal, our IP position
still remains strong.  Although the decision is disappointing,  these
patents apply only to certain activities  in UK waters and we  retain
full patent  protection in  more than  30 other  jurisdictions.  EMGS
remains the market leader in EM and the only company that can offer a
full suite of EM products globally.

"We have also announced today the decision of the Board to  undertake
a strategic review.   This step is  part of our  ongoing strategy  to
exploit  fully  the  commercial  opportunities  created  by  our   EM
technology."

About EMGS
EMGS uses its proprietary electromagnetic (EM) technology to support
oil and gas companies in their search for offshore hydrocarbons. The
company is the EM market leader and provides Clearplay, the world's
first fully integrated EM system.

Three service offerings - Clearplay Find, Test and Evaluate - have
been designed to assist operators in the exploration and production
phase. Clearplay supports each stage in the workflow, from survey
design and data acquisition to processing and interpretation. The
services enable integration of EM data with seismic and other
geophysical and geological information to give explorationists a
clearer and more complete understanding of the subsurface. This
improves exploration efficiency, and reduces risk and finding costs
per barrel.

conducted more than 400 surveys, improving drilling success rates
across the world's mature and frontier offshore basins. The company
operates on a worldwide basis with main offices in Trondheim and
