  3. Mozambique 2nd License Round – Rovuma Basin The Rovuma Basin is about 400 km long and 160 km wide (250 by 100 miles). The Rovuma Basin extends from the port of Nacala in to Southern Tanzania. The basin is located both onshore and offshore and within Mozambique covers over 30,000 sq.km (12,000 sq. miles). For the purposes of the bidding round the Rovuma basin has been divided into seven areas, one area onshore and six areas offshore

  4. Over 30,000 sq km Under explored Water depths from 0 to >2,500m Deep water never licensed Mozambique 2nd License Round – Rovuma Basin

  5. Rovuma Basin • Well Data • Old Offshore Seismic Data • Onshore Seismic Data • Modern Offshore Seismic Data • Gravity / Aero-magnetic Data • Satellite Data

  6. Rovuma Technical Data All Technical Data available for the bidding round: • Data Rooms • Landmark Project • SMT Kingdom Project • Data Package to include: • Information CD (Petroleum Law & Prospectivity Posters) • Country Overview Report • Digital Well Data • Digital Seismic Data • Field Work / Field Visits

  9. Well Ties • Mocimboa 1 - Esso / Shell

  10. Well Ties • Mnazi Bay 1- Agip DST 4 Flowed Gas at 393,800 m3/day

  11. Onshore Seismic Data

  12. Reprocessed – Onshore Seismic Data

  13. Lonropet Seismic Program • Acquired in 1998 • 3,600 Km 2D Seismic Data • Data shot and processed for Lonropet by Western Geophysical

  14. Field Work Program • Review of previous work • Seismic to surface geology ties • Seek possible source rocks • Seek possible reservoir rocks • Seek hydrocarbon seeps

  15. Review of previous work - Flores circa 1960 • Field Work, 1960 • Old Field Maps • Old Reports • Help to locate samples • Seep on Montipuez River ? 2000 - Florence 1960 - Mtwara Tar Sands

  16. Seismic to Surface Geology Ties

  17. Rovuma - Outcrops

  18. Field Work Summary • Sampled potential source rocks within the Cretaceous. • Sampled good quality reservoir rocks with high porosity • Sampled several oil seeps • Sampled gas seeps • Discovered Jurassic sediments within the Rovuma

  19. Structural Elements • Northern Area • Rovuma Delta • Southern Area • Ibo High • Palma Embayment

  20. Interpretation Overview • Tertiary Delta • Cabo Delgado • Ibo High • Pemba • Ibo North • Ibo Central • Ibo South

  21. Play Types: Ibo High Area

  22. Ibo North Prospect • GRV of 133 billion m3 assuming a thickness of 400m of Karroo sediments • Net to Gross of 20% • Porosity of 18% • Water saturation of 30% • Water depths of 500 - 700m • Depth to crest, 2300m • Four way dip closure (418km2) with 1100m of vertical relief • Triassic to early Jurassic fluvio-deltaic channel and sheet sands

  23. Interpretation Overview • Tertiary Delta • Cabo Delgado • Ibo High • Pemba • Ibo North • Ibo Central • Ibo South

  24. Play Types: Tertiary Delta Area

  25. Play Types: Tertiary Delta Area

  26. Play Types: Tertiary Delta Area

  27. Play Types: Tertiary Delta Area

  28. Rovuma Delta Reservoirs and seals Tertiary deltaic sands Seals Tertiary marine shales Source Jurassic and Cretaceous shale Play Fairways • Ibo High • Reservoirs • Karroo, Jurassic & Cretaceous • Seals • Karroo intraformation shale • Transgressive Jurassic and Cretaceous shales • Source • Karroo shale • Middle to Upper Jurassic Palma • Embayment and Rovuma Basin shale

  29. Leads & DHI Map Exploration Potential • Tertiary Delta Sector • Cabo Delgado, sub marine fan sand • Sub Thrust Play • Backwall Anticline • Fore-thrust Compressional Lead • Imbriacte Structures • Vanizi Lead • Ibo High Sector • Eastern Flank, Turbidite Fan Sands • Aptian Lead • Reactivation Features • Cretaceous Reefs • Southern Sector • Half Graben Lead

  30. Technical Summary • Initial exploration of the Rovuma Basin has shown it to be a multi-play and multiple prospect area with direct HCI’s • Exploration in the Rovuma is high risk but high reward • The most outstanding features identified are the “Tertiary Delta” in the north and the “Ibo High” horst trend in the south • Source and Reservoir rocks have now been sampled and identified within the Rovuma Basin • The Rovuma Basin has the potential to contain a world-class hydrocarbon accumulation

  31. Legal Framework

  32. Framework conditions • Core Elements of new regulatory structure: • Petroleum Law 3/2001 • Petroleum Regulations 2004 • New Model Exploration and Production Concession Contract Legend Administrative law Contract law INP_ Instituto Nacional de Petróleos

  33. Framework conditions System approach moving from traditional contract based system to a modernized EPCC system regulating relationship between State and commercial entities: Contract Law Admin Law Risk Service Contract Concession/ Licensing Production Sharing Contract Exploration Production Concession Contract Contract Increased reliance in new EPCC based system on legislation rather than contract clauses INP_ Instituto Nacional de Petróleos

  34. INP Organisational structure Petroleum law the legal foundation for the governance structure of petroleum activities clarifying roles and interests: Regulator Resource owner Commercial Interest

  35. FINAL REMARKS • Mozambique offers good exploration opportunities: • Good prospective acreage available • Favourable legal, regulatory and fiscal framework • Adequate infrastructure for natural gas transmission; • Political stability • Licensing Round to be announced, 15th of July 2005.
