Introduction to Liberia Petroleum Exploration Program

1. Welcome to NOCAL NATIONAL OIL COMPANY OF LIBERIA PRESENTATION BY J. S. SANDIKIE B.Sc., M.E.R. V.P. for Technical Services

2. General Introduction to the Liberia Petroleum Exploration Program

3. Brief History of the Oil Exploration Program In Liberia •  Petroleum Exploration began in 1948 in Liberia and stopped in 1972 for some years. • In 1980, the Government of Liberia (GOL) reactivated the project, through a US$5.0 Million World Bank loan to finance the project, aimed at evaluating the hydrocarbon potentials of the Liberian sedimentary basins. • AMOCO Liberia Exploration Company was awarded four (4) offshore permits in 1983 for petroleum exploration. AMOCO shot an extensive seismic survey and drilled three (3) exploratory wells offshore during 1983 and 1984.

4. Oil and Gas Exploration Wells Drilled Seven (7) exploratory wells have so far been drilled on the continental shelf of Liberia. See Map next:

7. The Onshore area of Liberia consists mostly of Igneous and Metamorphic Rocks. • Information gathered from outcrop and gravity survey show that there are two Coastal Basins in Liberia known as Roberts Basin and Bassa Basin respectively. • The Sediments from these Basins range from Paleozoic (?) to Recent, and lie on the Pan-African age Basement, filled with sediments ranging from few feet to much 10,000 feet in thickness. • To date, no well has been drilled onshore and detailed sedimentary sections are not known. ONSHORE SEDIMENTARY BASINS NOCAL

9. WELL CORRELATION DIAGRAM • The next diagram shows the stratigraphy of the wells including two wells offshore Sierra Leone. The horizons of oil prone source rocks are shown by the green bars along the side of the well stratigraphy. • Similarly, Horizons with mixed oil and gas prone source rocks are indicated by the green/red bars. • The Major Lithologies are colored as follows: • Blue - limestone • Yellow - sandstone • Green - shale • Brown - volcaniclastic sediments • Red - igneous lavas/intrusions

10. WELL CORRELATION DIAGRAM NOCAL

11. SOURCE ROCK • 4 wells had Early to Middle Albian oil-prone source beds with TOC’s from 1.9% to 5% • 1 well had Aptian oil-prone source beds with TOC’s from 1.0% to 3.0%

12. TRAP TYPES • Tilted Fault Blocks • Onlap Pinchouts • Deepwater Fans • Truncation Traps • Transpressional Structures • Structural – Stratigraphic combinations

13. RESULTS OF THE STUDIES • Seismic and well data collected from Liberia’s Offshore have identified • Oil Shows, • Good Reservoirs, • Source Rocks in the wells drilled, • Abundant reservoir quality sandstones, • Adequate seals, • Varied and abundant trap types and sizes, • Maturation is estimated to be after the cessation of tectonism • Other seismic data and regional analysis show Sedimentary features and structural traps identical to those in the other West African Countries with have proven mature source rocks containing oil and/or gas. • These factors are very similar to those of adjacent Côte d’Ivoire and other producing sectors of offshore West Africa

14. NATIONAL OIL COMPANY OF LIBERIA (NOCAL) • TGS-NOPEC geophysical survey • In 2000 TGS-NOPEC conducted a 9,500 kilometres 2D geophysical survey, comprising seismic, marine gravity and marine magnetic data, in water depths ranging from 500 to 4 000 metres. All wells were tied by the survey.

15. TGS-NOPEC CONTRACTED THIS VESSEL IN 2000 FOR 2D SEISMIC FOR NOCAL • NAN HI 502 • Client: NOCAL； • Field: Offshore Liberia • Operation: 2D Seismic Acquisition • Km of Seismic Lines: 9,500km

18. THE MAJOR OFFSHORE BASINS IDENTIFIED IN LIBERIA • Two major basins identified are the Liberia Basin and the Harper Basin separated by a broad arch, known as the Liberia High. • The Offshore Liberia basin complex is bounded on the Northwest by the Sierra Leone Transform System and on the Southeast by the St. Paul Transform System. • The total thickness of the Aptian – Tertiary sedimentary section ranges from 4,500 m. to 5,000 m on the shelf, to approximately 9,000 m in the basin depocenters

20. PRODUCTION SHARING AGREEMENTS • NOCAL presently has Production Sharing Contracts with the following five (5) oil companies for eight (8) blocks: • THE FIRST SET OF PSC’S NEGOTIATED ARE: • Repsol, a company operating under the laws of Spain, was awarded block number LB-17. • Oranto Petroleum Limited, a company operating under the laws of Nigeria, was awarded block number LB-12. • THE SECOND SET BY THE BIDDING PROCESS: • Consortium of Regal Liberia Limited and European Hydrocarbon (subsidiaries of Regal Petroleum plc), a company registered under the laws of U.K Block LB-8 and Block LB-9; • Oranto, a Nigerian registered company, block LB-11;   • Broadway Hydrocarbon plc, a U.K. registered company, block LB-13; • Woodside, an Australian registered company, block LB-15; and • Repsol, a company registered under the laws of Spain, block LB-16.

22. STATUS OF THE CONTRACTS • Three of the above contracts (Oranto Blocks LB-11 & LB-12, and Broadway Block LB-13) have already been ratified by the National Legislature. The others are pending conclusion of the review process. • THE REVIEW PROCESS: • A contract review process was put in place by the GOL in compliance with the agreement between the GOL and the International Community under the GEMAP (Governance and Economic Management Assisance Program) process. The GEMAP objective is similar to that of the Extrative Industries Transparancy International (EITI) process, which Liberia has also joined, and its framework aims for all parties (both Liberia and the International Community) to turn the page and get rid of previous malpractices that led to civil wars and self destruction in Liberia.

24. MANDATE OF NOCAL • The National Oil Company of Liberia (NOCAL) was established in 2000 with the mandate: • “To exclusively handle activities leading to its exploration, discovery and production;” and • “… holding all of the rights, title and interest of the Republic of Liberia in the deposits and reserves of liquid and gaseous hydrocarbons within the territorial limits of the Republic of Liberia, whether potential, proven, or actual, with the aim of facilitating the development of the oil and gas industry in the Republic of Liberia”

25. SOME CONTRACT & FISCAL PROVISIONS IN THE LIBERIAN MODEL PSC WE HAVE: • Cost Recovery % - Negotiable • No Royalty • Production Split – Negotiable • Taxes – Paid from Contractor’s Share % • Production Bonus but No Signature Bonus • Contributions to Hydrocarbon Development Fund and Training of Liberians • Surface Rentals • Minimum Work Obligation • Financial Expenditure Obligation • Negotiate Seismic and Drilling Obligations • We Focus on “Win-Win” Agreement • Our Terms are Among the Best of Any Country

26. A NEW LICENSE ROUND WILL BE DECIDED BY THE BOARD OF DIRECTORS OF NOCAL • License round will be officially announced at an appropriate time by the Board of Directors NOCAL. • As a Pre-License Round, Oil Companies are invited to purchase the TGS-NOPEC Data for study. • We are open to receiving proposals from companies and investors.

27. CONCLUSION • The results of exploration to date indicate a very promising future for hydrocarbon exploration offshore Liberia, • And we are very optimistic that oil prone petroleum systems occur in the offshore Liberia Basins • Our Contract and Fiscal Terms provide for incentives and focus on “Win-Win” Agreements that are among the best of any country.
