Brazil taps the ocean's riches tapping UNDERWATER OIL RESERVES


Τα νέα ενεργειακά αποθέματα που βρέθηκαν πρόσφατα στην Βενεζουέλα, με υπολογιζόμενα συνολικά αποθέματα που ξεπερνουν τα 100 ΔΙΣ βαρέλια, αλλά και της Βραζιλίας 50-80 ΔΙΣ βαρέλια καθιστούν την Λ Αμερική τον μεγαλύτερο μελλοντικό προμηθευτή αργου , ξεπερνώντας τα ταχεως εξαντλούμενα αποθέματα της Μ. Ανατολής.

Brazil taps the ocean's riches
BRAZIL TAKES ON THE CHALLENGE OF TAPPING ITS MASSIVE UNDERWATER OIL RESERVES

Associated Press
RIO DE JANEIRO -- BY BRADLEY BROOKS
Four miles under the ocean's surface off Brazil's lush coast lie billions of barrels of recently discovered light crude -- a treasure that could transform the country into an oil superpower.
President Luiz Inácio Lula da Silva called it ''a gift from God'' and pledged to end chronic poverty and narrow the country's broad gap between the rich and the poor.
But before rhetoric becomes reality, Brazil must first get to the underwater reserves, among the world's deepest, and then manage a massive influx of wealth -- a formidable task that has left other national economies awash in corruption and even greater gaps between the rich and poor.
Jockeying for a cut of the proceeds already has begun.
Military officials are calling for increased military spending, stressing the need for a nuclear submarine program and new fighter jet fleet to protect the oil from rivals.
The nine fields discovered in the last year are thought to hold 50 billion to 80 billion barrels of light crude -- more than four times Brazil's current proven reserves. With the find, Brazil could supply all of its own needs for nearly a century or become one of the world's top oil exporters.
Even getting to that point will test the state-run oil company Petróleo Brasileiro, which has decades of experience in deep-water drilling. The oil fields will be the most complicated and costly it has ever developed. Analysts say the project will require at least a $600 billion investment over 30 years.
The deep-water reservoirs lie some 185 miles offshore in the Atlantic, more than a mile below the ocean's surface and under another 2.5 miles of earth and corrosive salt. The salt beds can break loose and shear off piping, making it one of the toughest substances to drill through.
Given those conditions, rough ocean currents and floating rigs, the technology required to tap Brazil's so-called ''pre-salt'' oil is on par with that needed to land a man on the moon, said Eric Smith, a drilling expert at the Entergy-Tulane Energy Institute at Tulane University in New Orleans. ''If you were doing this with a drill from atop the Empire State building, about 1,000 feet up, you'd be trying to hit a target on 34th Street the size of a quarter,'' said Smith.
''Then you've got to go down an equivalent distance to reach the oil, and it might not be on 34th Street, it might be on 42nd Street,'' he said. Petrobras will use seismic imaging to map the reserves, but even that will not provide a clear view under the salt, which blurs images, said Judson Jacobs, director of upstream technology at Cambridge Energy Research Associates in Cambridge, Mass. Drilled wells must also withstand the pressure of extreme depths, Jacobs said.
But there are logistical problems beyond engineering.
The recent record prices for oil have led to global shortages of drilling equipment just when Brazil needs it most. The country will have to rent 138 drilling platforms -- or build them for as much as $1.7 billion each -- and find at least 200 ships to transport oil and gas over the next 30 years, a mid-September study by Brazil's national development bank found. The financial spillover could begin with Brazil's dormant shipping industry and create tens of thousands of jobs, Lula da Silva has said. Lula da Silva appointed a cabinet-level committee to draft plans for restructuring the oil industry to accommodate rapid growth. That committee is expected to recommend a new state-owned oil company negotiate contracts.
Petrobras will have to work with private partners, more likely through production-sharing deals than the current concession contracts it now favors, said Christopher Garman, head of Latin America research for the New York-based Eurasia Group consulting firm. Garman called fears of nationalism that once dominated Brazil's energy industry a bit ''overblown.'' Laws passed in 1997 broke the government's monopoly over Petrobras, allowing foreign investors to buy stakes in 60 percent of the company. About a million Brazilian citizens hold shares, too.
