3. 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).

11. 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

12. 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

13. 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 ( )
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

15. 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

16. 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

17. 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

18. Opportunities BIDDING ROUNDS:
