Petrobras begins extended well tests of the Tiro & Sidon accumulations in the Santos Basin



Petrobras has announced the beginning of the Extended Well Test (EWT) for the Tiro and Sidon areas, in the Santos Basin, by means of the installation of the semi-submersible SS-11 Atlantic Zephyr platform, which has a capacity to produce 20,000 barrels of oil per day (bpd) and to treat 475,720 cubic meters of gas per day.
The Tiro and Sídon deposits were discovered in July and September 2009, respectively, and are located in exploratory block BM-S-40 (100% Petrobras), in the south area of the Santos Basin, about 210 kms off the coast. The deposits are located in shallow waters, in the post-salt region, at a depth of 2100 meters and at some 250 meters from the water line.

The volume of recoverable oil has been estimated at 150 million barrels of oil equivalent. Early results indicate the presence of good quality oil (34 API). The production of the EWT, estimated at 10,000 bpd, will be stored initially in FSO Avaré and then transported to the mainland on shuttle tankers.

The Tiro and Sídon EWT will be carried out in two stages: (i) production in well 1-SPS-56, in the Tiro accumulation, for a period of 12 months; (ii) testing at well 1-SPS-57, in the Sídon area, for an equal period.

Exploratory activities in the region still includes the drilling of the well SCS-13, located east of Tiro and Sidon, at block BM-S-12, over the second quarter of 2010. Drilling activity already performed in this well indicated the presence of hydrocarbons and potential in the pre-salt area, which is the objective of this new drilling. The results are expected for the second half.
Regarding the EWT of Tiro and Sidon, the results of the test, added to the evaluation of nearby fields, such as Cavalo Marinho, Caravela, and Estrela do Mar, will be important to define both the future development of the discoveries made in the Southern Pole of the Santos Basin and the feasibility of installing an integrated production system in the region.

Petrobras to start pilot production at the Tupi oil field in October

* Pilot production originally set for December
* Move will boost Petrobras output earlier in the year
* Fourth well in Tupi area shows strong flow rates
* Offshore well could produce 30,000 bpd

RIO DE JANEIRO, March 23 (Reuters) - Brazil's state-run oil company Petrobras will move forward the start of a pilot production run at the massive Tupi field to October from December, Exploration and Production Director Guilherme Estrella said on Tuesday.
The move will bring 100,000 barrels per day (bpd) of new output online -- the first major production from the vast offshore subsalt region -- and help Petrobras boost 2010 output after slightly missing last year's production target.
"Without a doubt we will declare commerciality to begin the pilot program in October," Estrella said.
Tupi, which is believed to hold 5 billion to 8 billion barrels, is currently producing 18,000 bpd as part of an extended well test. Petrobras must declare commerciality to move to the next phase of development.

Estrella also said Petrobras will start drilling into the subsalt layer in the southern part of the Santos basin in May, Estrella said. Until now, most of the massive subsalt discoveries have occurred further north in the Santos basin.
He added the company will boost local content requirements for equipment and services that it procures to around 75 percent from 65 percent.
"It was set at 65 percent in Brazil in 2003, when the (services) industry was not developed. But today a lot more equipment is being made here ... which is why we can increase domestic content to more than 70 percent," he said.

Et Total n'est pas absent et cherches des opportunités.
Total, Europe’s third-biggest oil company, is seeking 'various opportunities' to buy stakes in oil projects in Brazil, country manager Patrick Pluen said. The company currently owns a minority stake in one offshore block in Brazil’s Campos Basin, Pluen said in an interview on the sidelines of a conference in Rio de Janeiro.

Japan’s Inpex Corp. and BP have bought stakes in Brazilian oil blocks this year as discoveries in the country’s pre-salt offshore region lure investments. Petrobras, Brazil’s state-controlled producer, raised its five-year investment plan to $200 to $220 billion as it taps deepwater deposits, including Tupi, the biggest find in the Americas since Mexico’s Cantarell in 1976.

Petrobras and Total will continue appraising the deepwater Xerelete discovery in the offshore Campos Basin to decide when to begin commercial production, Pluen said. The companies will explore deeper in the reservoir below the so-called pre-salt layer before setting a production schedule, he said. Petrobras operates the block. Total filed a declaration of commercial discovery with the Brazilian authorities for the ultra-deep offshore Xerelete (formerly Curió) discovery in September 2007. Discovered in 2001 by Total, then operator, the field extends over two blocks, Blocks BC-2 & BMC-14. Located in the prolific Campos Basin, 250 kms offshore Rio de Janeiro, Xerelete contains relatively heavy oil (17° to 20° API) and lies in 2,400 metres of water.

Le norvégien statoil espère débuter la production du champ Peregrino début 2011 avec une production au terme de la 1ere phase de 100 000 b/j.
Norway's Statoil Peregrino Field To Start Production In 2011

CARTAGENA, Colombia (Dow Jones)--Norway's state-run oil company Statoil (STO) expects its Peregrino oil field off the coast of Brazil to start production at the start of 2011, with production eventually reaching about 100,000 barrels of oil equivalent per day in its first phase of development, a top company executive said.

"We have two well-head platforms in place in Brazil, and we are constructing an FPSO (floating production storage and offloading vessel) in Singapore," said Thore Kristiansen, Senior Vice President of International Exploration and Production, told Dow Jones Newswires at the World Economic Forum on Latin America.
The field has the potential for further development, though this will require additional exploration in the area, said Kristiansen, who is responsible for Latin America and Sub-Saharan Africa for the company.
Statoil has seven exploration licenses in Brazil, and hopes to expand its portfolio in the country, the executive said.

Un article sur les presalt au Brésil, dans JPT (Journal of Petroleum Technology) :
http://www.spe.org/jpt/print/archives/2 ... Brazil.pdf
FINANCIAL INVESTMENT AND ECONOMICS
To develop the presalt will require estimated investment of a massive
USD 400 billion in the next decade alone, according to Haroldo Lima,
president of the Brazilian National Petroleum Agency. However, based
upon Petrobras’ evaluation of reservoir potential, its technology
path, master plan, and critical resources strategy, the company has
determined presalt development to be economically viable in a
price range of USD 35–45/bbl, depending upon the reservoir.
This is an enormous advantage that gives strong probability to
Petrobras’ forecast of its presalt production: attainment of 1 million
B/D of new production by 2017. Formigli places this in perspective.

“To reach 1 million B/D of oil production took Petrobras 45 years
from its founding [1954], and for the presalt we are planning to reach
this production in 12 years since the discovery,” he said. “But comparing
development that included significant onshore acreage to a
highly prolific offshore area like the presalt perhaps seems unfair. So
if you looked, instead, at just our offshore Campos Basin activity, it
took us 27 years to reach 1 million B/D of production—or 22 years if
you look at deep water alone.

To be able to add 1 million B/D in only 12 years, as we project
in the presalt, represents a tremendous acceleration of
development compared with anything in the past.”

Brésil : Technip remporte un contrat sur le champ Tupi

Technip annonce avoir remporté en avril auprès de Petrobras un contrat d'une valeur non divulguée et concernant des conduites flexibles du système pilote du champ Tupi.

Le contrat inclut l'ingénierie, la fourniture des équipements, la fabrication et l'approvisionnement de 90 kilomètres de risers(1) et de flowlines(2) pour l'injection d'eau, la production de pétrole, le gas lift et la réinjection de gaz carbonique (CO2).

Les challenges clés de ce projet sont dus à la grande profondeur d'eau et à la forte teneur en CO2 et en sulfure d'hydrogène (H2S) des fluides produits.

Les découvertes se succèdent puisque vendredi le brésil a annoncé qu'un nouveau puits ( Libra ) déteindrait sans doute plus de pétrole que franco annoncé récemment toujours dans le Bassin Santos.
Brazil announces Libra Prospect as major pre-salt oil discovery

16 May 2010

Brazil on Friday unveiled a second major offshore oil discovery in a week, bolstering the reputation of the South American nation's deep water fields as a major energy frontier. Brazilian regulators said preliminary estimates suggest the Libra Prospect may hold even more oil than the nearby 4.5 billion-barrel Franco find, though they are still waiting to finish drilling a well there to have a reliable estimate of potential volumes.
Brazil's subsalt may be vaster than previously imagined, with the latest discovery at Libra.
Both areas are in the pre-salt region, a vast geological formation about 200 km wide and over 800 km long off Brazil's southern coast. The area has reservoirs very deep below a salt layer on the ocean floor that has proven to hold enormous volumes of light oil - estimated at between 50 billion and 100 billion barrels of recoverable crude.

Magda Chambriard, director of Brazil's ANP energy regulator, said Libra had better prospects than Franco. Franco, in turn, was the world's biggest oil find since 2007, when Petrobras unveiled the biggest ultra-deep find in history with its 5 billion to 8 billion barrel Tupi field. 'I expect that (Libra) is very large, at first appearance it could be bigger than Franco,' Chambriard said.

The Franco discovery has boosted industry confidence in the area's potential, though details on the Libra discovery are still preliminary, said Ruaraidh Montgomery, senior analyst in Latin America Upstream Research at Wood Mackenzie. 'This is helping confirm what people have been hoping about the pre-salt,' said Montgomery. 'This all points to the continuing de-risking of the pre-salt play, because we once again have indications of large volumes and we have good progress in the other pre-salt projects.'

Libra will take another five months to complete drilling and Chambriard's statements were made based on preliminary seismic data. Petrobras is drilling Libra on behalf of the ANP and is 19 miles (30 km) from the Franco well that the ANP said on Wednesday had 4.5 billion barrels of oil. Chambriard added that in drilling the Franco field Petrobras encountered geological formations that suggest Brazil's subsalt may be vaster than previously imagined. But she declined to give further details.
Oil from those fields may be used in a government-backed oil-for-shares capitalization plan for state-run Petrobras that would provide it with billions of dollars in new cash needed for its 2010 exploration investments. The rights to the federally controlled oil will help Petrobras leverage it into capital to develop Brazil's vast subsalt oil reserves and expand Latin America's mining and farm commodities-rich export profile into hydrocarbons.
The ANP added that the oil field tapped by the Franco well is not linked to the 3 billion to 4 billion barrel Iara field that is controlled by Petrobras and its partners Portugal's Galp and Britain's BG.

50 à 100 milliards de barrils? Si il s'agit vraiment du brut, sans le gaz naturel ajouté dedans, on est en présence d'une nouvelle mer du nord.

La mer du nord a un ultime pétrolier (brut, condensats, LGN) de l'ordre de 65 Gb (milliards de barils)
* Norvège : 20 Gb déjà produits, peut être 10 restant (optimiste)
* UK : environ 24 Gb déjà produit, moins 5 restant
* Danemark : 3 Gb produit, 2 restants
(chiffres approx)


Note : Il s'agit de la mer du nord au sens strict, c'est à dire grosso modo bornée au nord et à l'ouest par les Shetlands.
La Norvège possède aussi du pétrole dans la mer de Norvège, environ 3 Gb déjà extraits et 2-3 restants. La Grande-Bretagne a aussi du pétrole dans l'Atlantic margin (à l'ouest des shetlands), ou environ 1Gb a été extrait et il en reste sans doute un autre.

On pourrait donc avoir au large du Brésil une nouvelle mer du nord. Avec des différences.

Si lors de son exploration dans les années 60-70 la mer du nord était considérée comme une région à couts élevés (par rapport au Moyen-Orient, au Texas, à l'Afrique du Nord, au Venezuela etc), elle ressemble aujourd'hui à une région low-cost comparée au Brésil ! La profondeur (à la fois prodondeur d'eau est profondeur sous le plancher océanique) extrême pose des difficultés énormes. Et des risques, comme les Américains viennent d'en faire l'expériance.

Le bassin de Santos est plus petit que la mer du nord, plus concentré, avec un petit nombre de gros gisement.

Et bien sur, il n'y a ici qu'un seul pays !

La production de la Mer du Nord a pîqué à 6 Mb/j en 2000, soit 35 après le début de l'exploration.
La tendance générale est d'exploiter les réserves de plus en plus vite, le bassin de santos devrait donc piquer plus et plus haut. Le rythme infernal auquel l'exploration est menée va dans ce sens.
Toujours moins.

Justement, suite à la marée noire de BP, est-ce que les assurances ne vont pas augmenter leurs prix renchérissant encore le coût de ces forages?

China, Brazil signs oil deal

26 May 2010

China Petroleum and Chemical Corporation (Sinopec) will import crude oil from Petroleo Brasileiro (Petrobras) with loans provided by China Development Bank (CDB) for 10 years in exchange for 10 billion U.S. dollars, Sinopec announced yesterday.

According to the agreement, 200,000 barrels crude oil will be provided to Sinopec each day.

Sinopec also signed a memorandum of understanding with Petrobras on exploration, equipment and service delivery.

Sergio Gabrielli, CEO of Petrobras said the 30 billion U.S. dollars loan from CDB and other banks will be used to exploit offshore oil off the coast of Brazil, which is to continue five years with 174 billion U.S. dollars investment.

According to data from China customs, Brazil exported 21 million tons of crude oil to China in April with 31 percent year-on-year growth. Brazil ranks tenth in China’s top 10 crude oil import countries.

Petrobras Uncorks Oil Offshore Brazil

June 04, 2010

Petrobras announced the discovery of a new accumulation of light oil (29o API) in the pre-salt layer in the Campos Basin, in water depths of 648 meters in the Marlim field Production Concession. The discovery was the result of the drilling of the exploratory prospect known as Brava, performed by means of well 6-MRL-199D-RJS, located 170 km away from the city of Macaé (state of Rio de Janeiro).

The accumulation discovered in pre-salt carbonatic reservoirs of the Aptian age, is nestled at a depth of 4,460 meters. Drilling was made to a total depth of about 5,000 meters to reach the reservoir, of which 1,000 meters of salt. Preliminary estimates indicate potential recoverable volumes at about 380 million barrels of oil equivalent there. Tests will be made to assess the productivity of these reservoirs.

The discovery is located in the area near the installed infrastructure in the Marlim and Voador fields, and the discovery well is located 4.5 km from the platform P-27, a fact that should not only facilitate field development, but also can reduce investments.

This accumulation will be the object of an Assessment Plan to be submitted to the National Petroleum Agency (ANP) soon.

Brazil announces new oil reserves

Sep 15, 2010

Brazil has confirmed discovery of another giant offshore oilfield, known as Libra, making it possibly the second-largest crude discovery of the last 20 years.

The oilfield that may be even bigger than the Tupi field in the Santos basin contains approximately 8 billion barrels of oil, vastly boosting a previous estimate of 5.5 billion barrels, a Press TV correspondent said on Monday.

Petrobras (Petroleo Brasileiro S.A.) is expected to raise as much as $130 billion, with almost $50 billion in new shares going to the Brazilian government in return for five billion barrels of its deepwater reserves.

The remaining cash -- approximately $80 billion -- will come from private investors; it is believed that this will meet the company's cash flow needs for extracting deepwater crude over the next few years.

Petrobras oil production could reach 6 million barrels per day by 2020.

The numbers involved are very high. Since Brazil's oil output to date has not been of global importance, it is therefore likely that politics will come into play.

How the country will manage the huge oil resources and income is yet to be seen. The Brazilian government maintains stock control over Petrobras, publicly held shares of which are likely to rise in value now.

Shell finds oil in Brazil deep-water subsalt block

Tue Sep 28, 2010

RIO DE JANEIRO, Sept 28 (Reuters)

Royal Dutch Shell told Brazil's oil and gas regulator ANP on Tuesday that it found oil in its subsalt concession block BM-S-54 in the Santos Basin.

Shell is 80 percent stake holder in the concession, with Total of France as partner. The block lies 200 kilometers (125 miles) off the coast of Rio de Janeiro state and the well is being drilled 2 kilometers (1.25 mile) below the ocean surface.

The company said it would continue drilling to 6 kilometers (3.7 miles), after which it will conduct an analysis of the flow and seismic data from the well.
