6. Historical Milestones
• 1997: Exclusive Agreement with STP
– 25 year term
– Over 50% of net revenues from all STP oil production in return for
• Mapping STP maritime boundaries and delineating Exclusive Economic Zone
• Developing STP oil industry, including establishing national oil company and licensing oil rights
• One-time payment of $5million
• 1997-1999: ERHC does the following:
– Pays $5 million
– Maps maritime boundaries and delineates EEZ
– Establishes national oil company (JV with government)
– Contracts for seismic acquisition
• 1999-2003: ERHC and STP renegotiate Agreement until:
– ERHC gives up all previous rights and entitlements in return for preferential minority rights in
• 6 offshore blocks in the Nigeria-STP Joint Development Zone (JDZ)
• 4 offshore blocks in the STP EEZ
• 2004: ERHC exercises preferential minority rights in the JDZ
• 2005-2006: ERHC teams up with International Operators to acquire additional rights (by
competitive bidding) in JDZ Blocks 2, 3 and 4

São Tomé and Príncipe
Exclusive Economic Zone
• Virtually surrounded by proven hydrocarbon
systems
• ERHC has a 100 percent working interest in Blocks 4
and 11
• Free of signature bonuses
• Additional rights to acquire up to a 15 percent paid
working interest in two additional blocks
• Cretaceous Turbidite fan deposits from offshore
Gabon may have formed traps in Blocks 4 and 11
• Similar fan plays led to the Jubilee Field discovery

EEZ Hydrocarbon
Resource Potential
• Evidence of a working hydrocarbon
system
– ExxonMobil: Extension of the North Gabon
petroleum system
– Oil seeps on the island of São Tomé
– Satellite-derived data : seeps in the offshore area
– A Lower Cretaceous succession increases the
likelihood that viable source rocks equivalent to
those in Gabon extend into the EEZ
• Prospective targets:
– Tilted block highs associated with the half-graben
development
– Draping of sandstone reservoirs over the underlying
tilted block of the distal equivalent of turbidite
fans that extend into the EEZ from Gabon and
Equatorial Guinea

11. 11
EEZ Hydrocarbon
Resource Potential
• Main reservoir horizons:
– Deep water Paleogene and
Cretaceous submarine fan sands
derived from the east
– Potential pre-rift and syn-rift
reservoirs in Cretaceous tilted fault
blocks and associated graben
• Large structural closures
within the Cretaceous section
apparently resulted from the
presence of large faults
associated with the major NE-
trending fracture zones

Conclusions
• There is evidence of a high quantity of hydrocarbon
resources in EEZ Block 11
– A linear fault trend extends from the NE corner of the block toward
SW, possibly merging into the São Tomé volcanic uplift
• This feature coincides with the Kirby Fracture Trend that runs exactly at the
same trend and direction
• This basin irregularity seems to have the largest displacement in the center of
Block 11, creating a mini-basin formation
• This allowed the accumulation of the oncoming sediments into the Block more
than the surrounding area
– The paleo-topography of Block 11 provided a favorable setting for
deposition of deep water turbidite fans during the late Cretaceous to
Early Tertiary period
– The fan system could be identified on the seismic on either side of the
basement fault trend (an area of approximately 3,500 sq km)

26. Summary
• Small Independent
• Sao Tome & Principe is important part of
ERHC’s heritage
• Formed JDZ exploration team that drilled in
JDZ Blocks 2, 3 and 4
• A positive force in building interest in STP’s
oil zones
