  1. E+P activities in South Africa Anthony Fielies Geologist - Petroleum Agency SA AAPG ACE Houston – April 2011

  2. Contents • Who we are? • Current activity • Why South Africa? • Sedimentary Basins • Onshore • Offshore – Orange Basin, Outeniqua Basin and Zululand/Tugela Basin • Conclusion

  3. Petroleum Agency SA • Promotion and Regulation of oil and gas exploration and production in South Africa 2. Archiving all data

  4. MPRDA: First point in the list of our responsibilities: Promote onshore and offshore exploration for and production of petroleum; OUR VISIONA viable, sustainable and responsible upstream industry in South Africa. OUR MISSIONTo promote, facilitate and regulate exploration and sustainable development of oil and gas in South Africa.

  5. Current Activity

  6. Why South Africa?

  7. Cont. • Africa’s most developed economy • Good infrastructure • Stable political climate • Excellent fiscal terms • Exciting frontiers

  8. Sedimentary Basins

  9. Onshore

  10. Onshore cont. CBM Biogenic Gas Shale Gas

  11. Onshore cont.

  12. Coalbed Methane (CBM)

  13. Biogenic Gas • Virginia and Evander gas fields • Found in gold mines • Witwatersrand basin • Associated with Helium • Monitoring wells

  14. Shale Gas • Primary Target • 10-80m thick • Highly Carbonaceous • TOC up to 17% • Regionally extensive • Exploration Well • 1.84 Million scf/day • ??TCF

  15. Moratorium on Karoo acreage • Not affecting areas applied for before 1 February 2011 • Planning bid round – to be announced (Government Gazette Vol. 548 No. 33988)

  16. Offshore

  17. Offshore – Orange Basin

  18. Offshore - Western Bredasdorp Basin OPEN ACREAGE

  19. South Coast – Open Acreage

  20. Western Bredasdorp Basin

  21. Mass-flow Hauterivian structure overlying 5At1 • Stratigraphic pinch-out against Central High • P50 estimate of STOIIP = 129 MMbbl • Volumetrics based on closing contour within open acreage PROSPECT P6: RINKHALS LEAD

  22. Summary of Western Bredasdorp prospectivity • 21 prospects delineated, untested • Proven oil & wet-gas prone source rocks • Short migration routes and effective charge • Oil expulsion throughout the Tertiary • Geological risk low on all aspects except seal • Central High area affected by intrusion activity 55 million years ago • Proven reservoir rocks • Potential hydrocarbon accumulations associated with bright spots

  23. Offshore – Durban/Zululand Basin

  24. Zululand Basin Durban Basin Offshore – Durban/Zululand Basin • Jurassic to Early Cretaceous • 7000km of 2D seismic • 4 Wells, exciting under-explored frontier • ER Silverwave Energy • Various leads identified

  25. The Lion lead • Cretaceous lowstand BFF complex • Stratigraphic trap • Sand prone • Water Depth's, 75-200m

  26. Located upthrown basement block • 1000m section draped • Water depth: 860 m • Source - Shales of Late Jurassic - Early Cretaceous • Reservoir - Marine sandstones

  27. Conclusion • South Africa provides abundant HC opportunities • SA regulatory and fiscal terms are highly competitive • The Karoo basin present opportunities • unconventional oil & gas exploration • coalbed methane , biogenic gas, shale gas • There is a lot of activity expected in the short to medium term • Shallow, deep and ultra-deep seismic acquisition • Deep and shallow waterdrilling of wells • Exciting!!!

  28. THANK YOU
