  3. KENYA SEDIMENTARY BASINS National Oil Corporation of Kenya

  4. OIL EXPLORATION HISTORY • 1950’S - Oil exploration commenced • 1960 to 1984 - 16 wells drilled mainly in the Lamu and Anza basins • 1981- NOCK was incorporated in 1981 • 1984 GOK enacted new Petroleum (Exploration and Production) Act. • 1986 Petroleum (E & P) Act revised. Royalties replaced by PSC’s • 1985 to 1992 - Further 14 wells drilled • 1995 - Lamu Basin Study completed. • 2001 - Tertiary Rift Study complete • 2000+ - Award of offshore PSC’s and reinvigorated exploration National Oil Corporation of Kenya

  9. Anza Basin Anza ANZA BASIN National Oil Corporation of Kenya

  10. HYDROCABON OCCURANCES IN ANZA BASIN • Lower Cretaceous Clastics flowed gas during DST (Ndovu-1 well) • Tarry oil associated with water in Sirius-1 well • Gas shows in Lower Cretaceous sands • Oil shows/flourecence/staining in aptian sands in Ndovu-1 well • Oil shows in: • paleogene in Hothori-1 well • Miocene to Cretaceous in Chalbi-3 well National Oil Corporation of Kenya

  11. Failed Rift system Permo-Triassic to Tertiary in age Sediment thickness ~ 10km Presence of hydrocarbons supported by > 200m thick sand impregnated with biodegraded asphalt Surface Geology of the Mandera Basin MANDERA BASIN National Oil Corporation of Kenya

  12. TERTIARY RIFT BASIN(s) • Consisting of at least 9 sub-basins • Oligocene to Pliocene in age • Sediment thickness up to 3 km • Potential reservoirs: up to 40% porosity in sands (Loperot-1 well) • Presence of hydrocarbons supported by oil recovered in Loperot-1 ~ 29o API National Oil Corporation of Kenya

  14. LOPEROT-1 WELL GEOLOGICAL COLUMN • Drilled by Shell in 1992 • Encountered excellent Tertiary reservoirs • Found source rocks with up to 7% Total Organic Carbon • Tested oil ~ 29o API National Oil Corporation of Kenya

  15. LAMU BASIN • Lies both onshore & offshore. • Formed during the separation of Madagascar from Africa • Sediments range in age from Upper Carboniferous to Recent • Sediment thickness of up to 12 km • The Tertiary section contains highly prospective source and reservoir units National Oil Corporation of Kenya

  16. SIMBA-1 W E 8km Tertiary Cretaceous Jurassic Triassic REGIONAL STRUCTURAL SETTING National Oil Corporation of Kenya

  17. LAMU BASIN EXPLORATION POTENTIAL • Gas and oil shows • Multiple tectonic trends with large faulted 4-Way dip closures off shore • Oil potential includes multiple petroleum systems ranging from Tertiary to Triassic National Oil Corporation of Kenya

  18. EXPLORATION OPPORTUNITIES • Open Blocks • 1 - 33,636 sq km • 2 - 15,528 sq km • - 24,539 sq km • 9 - 27,776 sq km • 10A - 15,289 sq km • 10B - 25,512 sq km • 11 - 35,786 sq km • 12A - 18,788 sq km • 12B - 4,169 sq km • L-1 - 19,305 sq km • L-2 - 21,979 sq km • L-3 - 9,636 sq km • L-4 - 7,025 sq km • L-10 - Offshore Lamu • Relinquished Acreage National Oil Corporation of Kenya

  19. KENYA – FRONTIER INVESTMENT • Political stability with positive investment climate • Large frontier (Onshore/Offshore) acreage • Competitive commercial terms • Acceptable balance of risk/reward. • Previous exploration data readily available. • Low entry cost, no signature bonuses • Award focuses on work programme • Provides investor with growth opportunities National Oil Corporation of Kenya
