Plentiful New Oil



Excellent article at Seeking Alpha by Jason Schwarz: The 'Peak Oil' Myth: New Oil Is Plentiful

The data is becoming conclusive that peak oil is a myth. High oil prices (USO) (OIL) are doing their job as oil exploration is flush with new finds:

1. An offshore find by Brazilian state oil company Petrobras (PBR) in partnership with BG Group (BRGYY.PK) and Repsol-YPF may be the world's biggest discovery in 30 years, the head of the National Petroleum Agency said. A deep-water exploration area could contain as much as 33 billion barrels of oil, an amount that would nearly triple Brazil's reserves and make the offshore bloc the world's third-largest known oil reserve. "This would lay to rest some of the peak oil pronouncements that we were out of oil, that we weren't going to find any more and that we have to change our way of life," said Roger Read, an energy analyst and managing director at New York-based investment bank Natixis Bleichroeder Inc.

2. A trio of oil companies led by Chevron Corp. (CVX) has tapped a petroleum pool deep beneath the Gulf of Mexico that could boost U.S. reserves by more than 50 percent. A test well indicates it could be the biggest new domestic oil discovery since Alaska's Prudhoe Bay a generation ago. Chevron estimated the 300-square-mile region where its test well sits could hold up to 15 billion barrels of oil and natural gas

3. Kosmos Energy says its oil field at West Cape Three Points is the largest discovery in deep water West Africa and potentially the largest single field discovery in the region.

4. A new oil discovery has been made by Statoil (STO) in the Ragnarrock prospect near the Sleipner area in the North Sea. "It is encouraging that Statoil has made an oil discovery in a little-explored exploration model that is close to our North Sea infrastructure," says Frode Fasteland, acting exploration manager for the North Sea.

5. Shell (RDS.A) is currently analyzing and evaluating the well data of their own find in the Gulf of mexico to determine next steps. This find is rumored to be capable of producing 100 billion barrels. Operating in ultra-deep waters of the Gulf of Mexico, the Perdido spar will float on the surface in nearly 8,000 ft of water and is capable of producing as much as 130,000 barrels of oil equivalent per day.

...

The peak oil theory is a money making scam put out by the speculators looking for high commodity returns in a challenging market environment. Most of the above mentioned finds have occurred in the last two years alone. I didn't even mention the untapped Alaskan oil fields or the recent Danish and Australian finds. In the long term, crude prices will find stability at historic norms because there is no supply problem. How much longer will investors ignore these new oil finds?

Technological Barriers To Carioca Field

Brazil Oil Trapped by 500-Degree Heat, Salt Barrier

Brazil's oil will be harder to develop than the Gulf of Mexico, where the deepest wells are now in production, Cline said. Exxon Mobil Corp. and Chevron Corp., the two biggest U.S. oil companies, saw diamond-crusted drill bits disintegrate and steel pipes crumple when they attempted to tap deposits beneath the Gulf's seafloor two years ago.

Uncharted Depth

Pumping oil from the Brazilian finds, parts of which are 32,000 feet (10,000 meters) below the ocean's surface, will require boring almost twice as far down as the world's deepest producing offshore well.

The obstacles will discourage development unless crude prices stay high, said Tina Vital, an analyst at Standard & Poor's in New York. U.S. oil futures, which reached a record at $119.93 a barrel in after-hours electronic trading yesterday, have jumped 81 percent in the past year.

Engineers will have to overcome temperatures that range from near freezing above the ocean floor to temperatures that can melt bismuth, used for transporting uranium rods and for shotgun shells. Layers of salt will also increase the challenge because the crystals absorb seismic waves used to pinpoint oil deposits.

Seismic Issue

``The seismic issue is important because if you don't identify the location of the oil properly, you're going to waste a lot of money when you drill the hole in the wrong spot,'' said Vital, a former Exxon engineer.

Brazil pumped 2.13 million barrels of oil a day in the last three months of 2007, more than OPEC members Angola, Libya and Algeria.

Tupi, 155 miles (250 kilometers) off Brazil's coast, may begin production by 2012, according to consulting firm Strategic Forecasting in Austin, Texas. The field may have 8 billion barrels of recoverable oil.

No start date has been set for Carioca, which Petroleo Brasileiro said will take at least three months to evaluate. A Brazilian regulator said this month the reservoir may have 33 billion barrels.

If confirmed by further drilling, the reserves will be triple the size of Alaska's Prudhoe Bay, the largest U.S. field.

Record Depth

The ocean-depth record for production was set last year by Anadarko Petroleum Corp. The company is extracting natural gas from beneath 8,960 feet of water in the Gulf of Mexico, where pressure measures 3,069 pounds per square inch, squeezing joints and tearing at seals.

``What we do at that water depth in the ocean is similar to NASA's space program, but they get to do it without any pressure trying to attack them,'' Kevin Renfro, production engineering manager at Woodlands, Texas-based Anadarko, said in a November interview.

Petrobras hasn't said how much it spent to sink wells at Tupi and Carioca. Similar drilling by Exxon and Chevron Corp. in the Gulf of Mexico cost $180 million to $200 million for each well.
