ERHC Energy Inc. is a US-based public company that holds oil and gas exploration licenses in São Tomé and Príncipe, Nigeria, Kenya, and Chad. The company has a long history of exploration activities in São Tomé and Príncipe dating back to 1997 and holds exploration blocks 4 and 11 in the country's exclusive economic zone. ERHC has identified potential hydrocarbon resources in Block 11 based on seismic data interpretation showing deepwater turbidite fan deposits and a basement fault that could have trapped hydrocarbon accumulations. The company aims to further explore and appraise the hydrocarbon potential of its licenses.

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
