As a result of recent discoveries in its deep and ultradeep waters, Angola is poised to jump its oil production to 2 million b/d by 2007, said analysts at Merrill Lynch & Co. Inc.

Deepwater projects currently under development, coupled with others "to be tendered in the near future," could "more than double" Angola's production capacity to 2 million b/d by 2007-08, up from about 900,000 b/d today. "Given the recent ultradeepwater successes and [drilling] success rate to date in this area, we believe that there could be potential for Angola to exceed 2.5 million b/d by 2010," Merrill Lynch analysts reported recently.

Conservation policy

Recent ultradeepwater discoveries off Angola could "ease government fears that it has an insufficient reserve base to support expanded production," the analysts noted. Last year, the Angolan government through national oil company Sonangol EP established a conservation policy of phasing development of its natural resources.

"The basis for Angola's conservation policy is that it believes there are insufficient proven and probable reserves to justify a large production base," said analysts. "Projects currently under development or those slated for development before 2007 will not be affected. However, the risk of delay could impact the pace of development of additional projects, particularly the potentially giant new discoveries in the ultradeep water."

Angola's proven and probable reserves currently are estimated at 11 billion bbl, not including recent ultradeepwater discoveries. "Without the addition of more reserves beyond what has already been discovered and once production rises to the estimated 2 million b/d mark in 2007, Angola will have a reserve-production ratio of just 9 years," analysts said. By comparison, they said, Nigeria, with its current reserves and projected 2007 production, has a ratio in excess of 30 years.

Last year, the Centre for Global Energy Studies reported that international oil companies' development plans for deepwater projects off Angola indicated that country's oil production "will overtake that of Libya by 2006." Angola now is the third largest African oil producer behind Nigeria and Libya, having surpassed Egypt and Algeria after production began from Girassol field (OGJ Online, Mar. 27, 2002).

Government transparency

An emerging governance issue in Angola is that of "transparency in terms of the accountability of oil revenues from the country's rising oil production base," said Merrill Lynch analysts.

"Human rights groups, the International Monetary Fund, and even the UK government have recently been highly critical about the lack of democracy and accountability in the country. BP (PLC) has come under pressure in the past for not disclosing bonus payments to the government," they said. "This lack of transparency is potentially a destabilizing risk, which, if interpreted by US President George Bush's recent trip to Angola, is receiving increasing international attention."

Still, they noted that US Department of Energy officials are expecting West African oil to account for 20% of total US oil imports beyond 2005, "of which a large portion is expected to come from Angola."

International companies

In 2001, three international oil companies accounted for almost 60% of Angola's total oil production. These included ChevronTexaco Corp. 28%, Total SA 21%, and ENI SPA 9%. Sonangol made up the bulk of the remaining production at 29%.

However, the Merrill Lynch analysts said, "As the new deepwater projects come on stream, we expect Sonangol's share of total production to fall to around 14% by 2007, with a number of new players contributing production for the first time." Among those companies expected to have Angola production are BP, the Royal Dutch/Shell Group, ExxonMobil Corp., Statoil ASA, and Norsk Hydro ASA.

"We expect the new entrants to deploy on average around 10% of [their] total upstream [capital expenditures] to Angola over the 2003-07 period (with the exception of Shell that is investing less than 2% of total group capex on our estimates)," said the analysts. "Statoil has the highest capital exposure to total capital spending with around 14% of capex [$1 billion] dedicated to Angola."

In terms of total spending, however, they said, "ExxonMobil leads with $4 billion of planned investment. BP has the second highest capex exposure over the period with approximately $3.7 billion slated for its developments in Blocks 15, 17, and 18. Total's capex exposure is a more modest $2.3 billion and reflects the fact that the company has already made a heavy investment in the Girassol field, brought on stream in late 2001."

Angola represents "a material source" for potential growth for all of the participating integrated majors, "except for Shell," analysts said. "Statoil has the greatest contribution to total growth from Angola, followed closely by ENI. It is also worth noting the importance of Angola to the medium-term capacity prospects for ExxonMobil, with close to 30% of growth expected to come from this source."

Discoveries

Drilling activity off Angola is booming, with eight wells drilled this year, resulting in three discoveries in ultradeepwater Blocks 31 (BP operated), 32 (Total operated), and 33 (ExxonMobil operated) this year, said Merrill Lynch analysts.

"In addition, three discoveries have been made in deep water, two in Block 17, [Total operator], where oil is already being produced from the Girassol field, and most recently one [on] Block 15 [ExxonMobil operated]," they said.

Other finds include "Hortensia and Acaccia in the Total-operated Block 17 [where 14 discoveries have now been made] and most recently the Clochas discovery by ExxonMobil in Block 15," the analysts reported (see related story, p. 38).

The Clochas-1 discovery, 240 miles northwest of Luanda, encountered an oil-bearing reservoir that flowed 1,764 b/d on test. It was drilled in 4,250 ft of water to 10,300 ft TD. Partner Statoil ASA said Esso estimates Clochas-1 to be capable of flowing slightly more than 5,000 b/d. Statoil and Sonangol are partners in that discovery (OGJ Online, Aug. 4, 2003).

They reported an additional five projects are under development, including ExxonMobil's Kizomba A, Kizomba B, and Xikomba, all in Block 15; and Total's Jasmin and Dalia projects in Block 17. "These five projects have the capacity to add 730,000 boe/d by the end of 2006 and will require around $12 billion to develop 4 billion bbl of estimated reserves," said analysts. "The two additional projects likely to be tendered before the end of the year are Rosa/Liro [Block 17] and Greater Plutonio [BP, Block 18] with capacity to add another 330,000 b/d by 2007-08," they said.

The larger Kizomba A and B developments are designed to recover 1 billion bbl of oil each. First production is anticipated from Kizomba A in 2004 and Kizomba B, which has been approved, in early 2006. Development planning for Kizomba C also is under way (OGJ Online, Aug. 4, 2003).

First oil is expected late this year from Xikomba field, which will use an early production system to recover about 100 million bbl of oil.

Earlier this year, Sonangol gave Total a green light to develop Dalia field, requiring an investment pegged at $3.4 billion. Jasmin is a satellite field due to start producing in the second half of this year through a tie-back to Girassol, which came on stream in 2001 (OGJ Online, May 6, 2003).

In January, BP awarded a contract for classification and verification of its planned Plutonio floating production, storage, and offloading vessel to Paris-based Bureau Veritas. The proposed FPSO, with a 2 million bbl storage capacity, is designed to serve six fields on Block 18 off Angola in 3,863 ft of water. Slated to be on stream in 2007, it will be anchored in deep water in Plutonio field with subsea tie-backs to Platina, Paladio, Galio, Cromio, and Cobalto fields within the block (OGJ Online, Jan. 7, 2003). BP operates Block 18 on behalf of itself and 50:50 partner Royal Dutch/Shell.

Development of deepwater projects off Angola is expected to require investments of some $26 billion in 2003-07, the analysts said.

"The giant signature bonuses [totaling $1 billion] paid [by the participating international oil companies] in 1999 to access acreage in the Angolan ultradeep water now appear to be bearing fruit after some initial disappointment," said Merrill Lynch analysts. They cited BP's recent announcement of its successful test of the Saturno discovery well in Block 31. Saturno-1 was drilled to 4,707 m TD in 1,804 m of water some 170 km off Angola. On test, it flowed 5,000 b/d of oil (OGJ Online, July 28, 2003). It was the third exploration well BP drilled on the block and the second successful find, following the discovery of Plutão field in the third quarter 2002.

In May, Total announced its Gindungo discovery in Block 32.

Three discoveries out of eight wells drilled puts the drilling success ratio at 38% in Angola's ultradeep waters—"fairly impressive for a new frontier province with significant challenges and no previous exploration history," analysts said. "While further appraisal work will be required on all three ultradeep discoveries, initial estimates have pegged [them] at up to 1 billion bbl each."
