           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
        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.

          São Tomé and Príncipe Seeps

• 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

  Gas escaping at Ubabudo-1

• 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.
