The Cretaceous Play Exploration Overview
"The Cretaceous Fan/Channel Play"
PanAtlantic
Also known as the "West Africa Transform Margin Play" (WATM); consists of a series of Upper
Cretaceous deep-water slope and basin floor fans and channels within structural/stratigraphic
traps, currently being explored along the Equatorial margins of Africa and South America;
Since 2000, >100 wells have been drilled in the play*
⚫First and second commercial successes: Ghana
o Jubilee complex (2009): about 700 mmboe recoverable
o TEN complex (Tweneboa-Enyenra-Ntom me, 2013): about 360 mmboe recoverable.
• Next commercial successes: Ghana - Tullow/Kosmos/Anadarko MTA (Mahogany-Teak-Akasa)
and ENI (Sankofa/Gye-Nyame); Hess (Pecan et. al) still pending Pre-Dev work; Nigeria? - Yinka
Folawiyu (Aje), Afren (Ogo) unclear
•
Play contains hydrocarbons in:
o Africa: Ghana, Guinea, Sierra Leone, Liberia, Côte d'Ivoire, Benin, Nigeria (far NW offshore), Equatorial
Guinea
o South America: Brazil, French Guiana, Guyana, Trinidad
• Critical technical risks
o Access to charge/charge focus and volume
○ Trap definition - where are the potential leak points?
o Reservoir presence and deliverability
o Hydrocarbon phase - spotty success with AVO and attributes
• Critical commercial risks: Gas utilization and commercialization; F&D costs; Contractor take, etc.
