OVERVIEW OF TANZANIA HYDROCARBON POTENTIAL & EXPLORATION STATUS Presented at the : American Association of Petroleum Geologists (AAPG) International Conference & Exhibition INTERNATIONAL PAVILION HOUSTON, TEXAS 12THAPRIL 2011
Presentation Outline • Key Legislations • Sedimentary Basins of Tanzania • General Exploration Activities & PSAs Status • Discoveries • Deep sea Exploration • Gas utilisation • Opportunities
Key Legislations • Exploration of oil and gas in the United Republic of Tanzania is governed by three main key legislations; • Petroleum (Exploration and Production) Act, 1980 • Income Tax Act 2004 • National Environmental Management Act 1983 Exploration and Production of oil and gas is carried under a Production Sharing Agreement (PSA) between three parties namely; the Contractor, the Government and the National Oil Company (Tanzania Petroleum Development Corporation (TPDC).
General Exploration Activities (Ctn…) Seismic Coverage by December 2010
General Exploration Activities (Ctn…) • Wells drilled to date • ONSHORE 49 • DEEPSEA 3 • Exploration wells in year 2011 • ONSHORE 3 • DEEPSEA 2 (PETROBRAS)
General Exploration Activities • Discoveries and Reserves
Production Sharing Agreements (PSAs) status A total 19 Companies are actively engaged in Expl. & Production
Deepsea Exploration • Deep sea exploration-related activities: • Meteocean studies • Seismic operations • Establishment of Mtwara Supply Base • Drilling operations • Seabed Surface Geochemistry and Heat Flow Survey in Block 2
Meteocean Studies • Aim: To determine the behavior of the • Indian ocean in terms of wind, • currents and waves • Methodology: Installation of buoys in • deepwater which recorded • continuous readings for one year • Time: Year 2010 in the deepsea area of • Tanzania and Mozambique • Operators: Statoil, Ophir Energy, • Petrobras, Dominion, • Anardako • Benefits: Planning in fabrication, • installation of offshore structures
Seismic acquisitions in deep sea • Seismic acquisitions carried out in the deepsea include: • 2D by Lamont-Deherty Geological Observers (LDGO lines-old seismic data) (197..) • 2D by WesternGeco (1999-2000) • 2D Long offset by ION-GXT and TPDC • EastAfricaSPAN 1 - (2006) • EastAfricaSPAN 2 (2008) • EastAfricaSPAN 3 ( APRIL 2011) - Both 2D and 3D in Blocks 1,2,3,4,5,6, and 7 by respective Operators
EastAfricaSPAN (1, 2 and 3) EastAfricaSPAN 3 seismic lines are shown in RED colour
Establishment of Mtwara Port Supply Base • Refurbished Port • located in Mtwara in • south east of Tanzania • Purpose: To support oil • and gas drilling • operations in the • deepwater • Built by Ophir Energy & • Petrobras
Deepsea Drilling operations • Recent: The first three deep offshore wells were drilled between September 2010 and March 2011 • Pweza-1 • Chewa-1 • Chaza-1 • Status: All are gas discoveries • Offshore wells to be drilled in 2011 : • Block 5 (2 wells) in 2011
Seabed Surface Geochemistry and Heat Flow Survey • The objective of the survey is to identify naturally leaking hydrocarbons and to measure temperatures within the sea floor • Coring to be carried out between May and June 2011 by TDI BROOKS for STATOIL in Block 2
Opportunities • BIDDING ROUNDS: • Mini bidding round currently going on for North Lake Tanganyika block (modern rift system). Bidding will close on 7th June 2011 • 4th Offshore Bidding Round. Licensing round will be launched sometime next year (2012).
Contact Details • Data package available for North Lake Tanganyika Exploration area include: • seismic sections on paper (seismic atlas) • Various reports For any inquiries kindly contact our Booth at the International Pavilion OR consult the MANAGING DIRECTOR of TPDC at the following address:
4th Offshore bidding round • The bidding round will offer areas which include new and relinquished blocks in the deep sea in water depths (2,000m-3,000m) • Data packages will include: • 2D Speculative seismic data by WesternGeco • 2D seismic data by GX Technology (EastAfricaSPAN 1, 2 and 3) • 2D seismic data by Operators in relinquished blocks • Public domain well data • Associated interpretation reports
