3 WGP Survey Ltd Company Services P-Cable Technology Development Data examples OUTLINE

4 WGP Survey Ltd was established in 2012 and is a Joint Venture company between WGP-Group and Fjorgyn AS. The purpose of the joint venture is a collaboration and union of WGPs operational experience and capability, coupled with the technology and know-how that P-Cable 3D Seismic has developed and patented. Together, the partners shall perform 3D seismic data acquisition surveys utilising the P-Cable 3D Seismic System. COMPANY

5 Thalassa Holding Ltd P-Cable 3D Seismic AS WGP Group Fjorgyn AS COMPANY STRUCTURE

6 WGP Exploration Ltd Formally part of the Westland GeoProjects Ltd group which was family founded in 1991, WGP Exploration was incorporated in 2009 and acquired by Thalassa Holdings Ltd on the 16th November It is the operational division of the Group with experience of conducting seismic survey operations in the marine environment for major E&P companies. WGP Energy Services Ltd Established to acquire marine seismic equipment, initially Portable Modular Source Systems ("PMSS"). Thalassa Holdings Ltd Listed on the Alternative Investment Market of the London Stock Exchange on 29 July 2008, with symbol "THAL".

7 Fjorgyn AS Was established as a service company in The company provide a turn-key solution for services with the P-Cable seismic system. Fjorgyn AS is the active partner in the WGP Survey Ltd Joint Venture. P-Cable 3D Seismic AS P-Cable 3D Seismic AS was established in The company is a R&D company with the main focus on developing and commercializing the P-Cable seismic system. P-Cable 3D Seismic owns all commercial rights to the P-Cable system.

8 With 10 years of experience using and acquiring data with the P-Cable 3D Seismic System + 20 years of marine survey knowledge SERVICES We provide together with partner companies a full turn-key solution for our clients.

17 Insert 2007 P-Cable survey showing auto-tracked interpretation based on the high resolution seismic. High level of structural details showing a variety of glacial features (although some acquisition imprints are visible. Notice how the GP3 gas producer (location based on conventional seismic) is located in a deep plough mark feature previously invisible. This illustrates a key benefit of using P-Cable high resolution 3D seismic in the field development. 35/2-1 N Data by Statoil P-Cable Overlying Conventional 3D | PEON D survey 2007 P-Cable
