8. São Tomé and Príncipe Exploration History Pre 1970 Oil seeps on the islands have attracted interest 1970 Ball & Collins licensed onshore and shallow offshore – drilled two shallow wells near seeps 1990 Island Oil drilled two deep onshore wells near seeps, including Ubabudo-1 drilled to 1501m 1998 Mobil held 18 month Technical Assistance Agreement for whole STP offshore 2001-2005 PGS acquired 10,000 km of 2D seismic in EEZ and 3000 sq km of 3D in JDZ

9. JDZ Update JDZ is a Zone established on 21 February 2001 by the Abuja Treaty, jointly controlled by the Federal Republic of Nigeria and Democratic Republic of São Tome and Principe for the purposes of the exploration for and exploitation of resources,aimed at achieving optimum commercial utilization for two countries. 2003 and 2004 JDZ Licensing Round produced 4 active production sharing contracts,for Blocks1-4. The Blocks 5-6 are yet to be concluded. The recent drilling operations for the JDZ Blocks 1-4 have encountered some very good reservoir sands, many of them charged with oil and natural gas.

10. STP 1 st Licensing Round - Summary License Round opened on the 2 nd March 2010 The License Round will close on the 15 th September 2010 The Licensing Round is based on open tender. Applicants will be assessed based on evaluation criteria The State reserves the right to participate in petroleum operations.

19. São Tomé and Príncipe Seeps Gas escaping at Ubabudo-1 Cretaceous oil is currently seeping in to this concrete emplacement of an artesian well on São Tomé. Natural oil seeps from both islands belong to separate oil families, although similar in appearance and viscosity. –São Tomé similar to Azile and Anguille Fm sourced oils in Gabon. –Seeps in Príncipe more mature. –Slicks observed offshore Príncipe

20. Reservoir Good quality sands have even been deposited as far south as Sao Tome. This slide shows some outcropping quartzose sands on the island together with a well drilled through several hundred metres of sands alternated with shales and volcanics, tentatively equivalent to the Agbada Formation.

21. Model PSC P RODUCTION S HARING C ONTRACT Applicants should take due notice that the PSC is based on an administrative law in which a specific number of fiscal elements are non- negotiable.
