The following companies are involved in the oil industry in South Sudan.

White Nile | Total | Shell/BP | Petronas | Talisman Energy Inc | Lundin Petroleum | China National Petroleum Corporation (CNPC) | Sudan National Petroleum Corporation (Sudapet) | Greater Nile Petroleum Operating Company Ltd (GNPOC) | PetroSa | Petrodar Operating Company Ltd (PDOC) | Advanced Petroleum Company (APCO) | Higleig Petroleum Services and Investment Group (HPSIG) | ONGC Videsh Limited (OVL) | Greater Nile Oil Project (GNOP)




Total, through its subsidiary Total E&P Sudan, signed an Exploration and Production Sharing Agreement (EPSA) with the Government of Sudan on blocks in southeastern Sudan in 1980 including block B, the main area for Total’s exploration activity in Sudan alongside partners:

  • Marathon Petroleum Sudan Ltd (32.5%, United States)
  • Kufpec Sudan Ltd (25%, Kuwait)
  • State-owned Sudapet (10%)

However, security issues in the region caused the suspension of exploration operations - Total were about to drill 3 oil wells - in 1985 with the agreement of the Sudanese government under a Stoppage Period provision. From 1985 to 2004 the Government of Sudan extended the Stoppage Period annually in which Total retained all of its rights on block B and kept a minimal presence on site.

In late December 2004, Total and its partners signed the Revised Exploration and Production Sharing Agreement with the Sudanese authorities to update the 1980 contract and to take account of new international industry standards, particularly in relation to corporate social responsibility, and to establish the terms and conditions for a resumption of operations in Sudan.

On 1 February 2005 Total E&P Sudan's representative was appointed in Khartoum and later in July received from International Crisis Group (ICG) an opinion on the Peace Agreements and on the White Nile issue.
However in May 2006, in accordance with Total's request, the High Court of London passed a judgement ordering White Nile to disclose documentation evidencing its alleged rights on part of block B.




Petroliam Nasional Berhad (PETRONAS) is Malaysia's national petroleum corporation incorporated in 1974 and wholly owned by the Government. The corporation is vested with the entire oil and gas resources in Malaysia and entrusted with the responsibility of developing and adding value to these resources.

Petronas has major interests in Sudan’s oil fields that include:

  • Block 1, 2, & 4 (Exploration, Development and Production)
  • Block 3 & 7 (Exploration and Development)
  • Block 5A (Exploration and Development) and 5B (Exploration)
  • Block 8 (Exploration)
  • Block 15 (Exploration)

Crude oil production in Block 5A begun in June 2006 in Thar Jath field (54km2) which is located in Muglad Basin. White Nile Operating Company Ltd currently operates the production in partnership with Petronas, ONGC Videsh Ltd of India and Sudapet of Sudan with expected initial production rate of 20,000 barrels per day (BPD).

Talisman Energy Inc

An independent upstream oil and gas company with headquarters in Calgary, Canada.

Lundin Petroleum

Talisman Energy - a Canadian independent - that included exploration assets in Sudan, formed Lundin Petroleum AB in 2001 as a result of a takeover. Lundin Petroleum holds a 24.5% interest in Block 5B that covers the southern part of the Muglad basin and is on course to strike and begin crude oil production as is being done in block 5A. Block 5B is a large block of 20,119 square kilometers and is located in the Sudd swamp. The effective date of the Block 5B Exploration Production Sharing Agreement is May 2, 2001 with a contract for up to 25 years with a 6 years exploration phase. Petronas and Sudapet jointly operate this contract.

In April 2003 Lundin Petroleum sold its 40.375% interest and operatorship in Block 5A to partner Petronas Carigali Overseas for the sum of US$ 142.5 million.

During 2007, activities have been delayed due to the slow implementation of the Comprehensive Peace Agreement which required the setting up of institutions to deal with the oil issue. This took place in 2007 when the National Petroleum Commission gave its endorsement of WNPOC and its right to conduct operations in Block 5B. Exploration drilling is expected to begin in Q1 2008.

On the ground operations began in earnest in 2006, with some 440 km of seismic data being acquired, and continued into the first half of 2007 as a further 600 km of data were recorded. Parallel studies using this and older seismic led to the identification of a series of relatively shallow structural closures analogous to those successfully drilled in neighbouring Block 5A.

China National Petroleum Corporation (CNPC)

CNPC has been present in Sudan since 1996 and now has oil and gas assets and interests in the country, while also providing oilfield services.

CNPC's oil and gas businesses in Sudan mainly include the projects of Block 1/2/4, Block 3/7, Block 6, Block 15, the Khartoum Refinery, Khartoum Chemical I Co. Ltd. and the petrochemical trade, covering oil and gas exploration, development, production, storage and transportation, refining and chemicals and sales of refined products.

On August 30, 2005, CNPC, Petronas, Nigerian Express, Sudapet and the Hi-tech Group sign a production-sharing contract with the Sudanese Government to explore and develop oil and gas in Sudan's Block 15.
Located in the northeastern part of Sudan, Block 15 covers an area of 24,377 square kilometers, most of which is located in the Red Sea. Two small-scale gas discoveries existed in the contract block. This contract was the Sudanese government's first offshore exploration and development contract, and also the first gas exploration and production sharing contract.

Sudan Block 1/2/4 is located in the Muglad basin, 700km southwest of Khartoum and covers an area of 49,000 square kilometers. Exploration of the area started in the 1980s, yielding 180 million tons of proven oil in place and 69.74 million tons of probable oil in place. CNPC won its bid for the block on December 2, 1996, and formed a joint operating group with the Sudan National Petroleum Corporation (Sudapet), Petroliam Nasional Berhad (Petronas), and Canadian STATE Petroleum Company. The block produced a total of 11.04 million tons of crude in 2001, with daily production standing at 32,900 tons as of the end of the year.

As a general contractor, CNPC has completed the construction of a range of major projects, including oilfield surface engineering of Block 1/24, Block 3/7 and Block 6, the 1,506-km long pipeline between Heglig and Sudan Port, the 716-km long pipeline between Block 6 and Khartoum Refinery, the viscosity- breaking unit for Block 6, the phase I construction and phase II upgrade of Khartoum Refinery and the polypropylene unit. The 1,506-km long pipeline from Heglig to Port Sudan, with an annual crude delivery capacity of 12.5 million tons, was completed within 11 months.
