El peak oil no se refiere a si el petroleo se va a acabar o no, sino a que es cada vez mas difícil llegar a él y extraerlo y se relaciona con la TRE ( tasa de retorno energético): cuantos barriles de petróleo se debe invertir para extraer 1. Al comienzo de la extracción, allá por 1850, la tasa era 100 a 1, es decir para extraer 100 barriles había que invertir 1. Hoy en día esa tasa anda por el 15 a 1 o 10 a 1, no esta determinado con exactitud. EL PROBLEMA llegará cuando esa tasa sea 1 a 1 o 0,87 a 1 ( es decir para obtener 1 barril de petroleo debo invertir 103 dolares - precio de hoy del WTI)

Me quita usted un peso de encima. Estaba preocupado por las consecuencias del contraembargo petrolífero de Irán a la UE, particularmente sobre los estados más dependientes como Grecia o España, y en general por las tensiones que han llevado al precio a cerca de los 120$. Menos mal que gracias a las inagotables reservas de petróleo abiótico vietnamita y ucraniano extraido de la base cristalina precámbrica (supongo que sin posibilidad de migración desde otro terreno sedimentario próximo) saldremos adelante. Sólo falta que usted y el señor Roco39 encuentren petróleo abiótico en el subsuelo granítico de Madrid para que mi tranquilidad sea completa.

Me asombra la inteligencia de Hannover,empeñándose en que le demostremos la teoría de la formación del petróleo,cuando es él quien debiera demostrar su absurda hipótesis.

Nada,y digo nada,apunta a lo que quiere hacer creer a los más incautos.

RIO DE JANEIRO - Brazilian energy giant Petroleo Brasileiro SA, or Petrobras, announced Friday that it has found light oil in deep waters off the nation's coast in a block jointly exploited with foreign firms.

A company statement said the discovery was verified by oil sampling in tests performed in reserves located at an approximate depth of 5,250 meters.

The new well, named Cariocal Sela, is in block BM-S-9 of the so-called pre-salt oil reserves, off Brazil's southeast Atlantic coast beneath kilometers of ocean, bedrock, and hot salt-beds.

The National Petroleum Agency estimates that these huge pre-salt reserves, discovered in 2010, could hold more than 100 billion barrels of high-quality recoverable crude.

The Petrobras statement said 27 API oil--petroleum liquid above 10 on the API scale is termed light oil--was recovered at a depth of 2,149 meters in the well 270 kilometers from the coast of Sao Paulo state.

Providence Oil to Start Flowing This Week

Providence Resources saw its share price shoot up last week after announcing promising appraisal results, but it faces an even bigger week ahead with an expectation that oil will flow at its Barryroe well in the waters off Cork. This will make it the first ever commercially-viable well to flow off the Irish coast.

"It is going to be a hugely important week for us," said Providence chief executive Tony O'Reilly. "At the end of the day, while geologists and people in the industry know the facts and figures that we have already put out, the market wants to see flowing black crude."

Shares in the company jumped last week after it said the Barryroe appraisal well has so far provided better than expected results, but the coming week could be even more important for Providence, said O'Reilly.

"When it does flow in the next few days, it will be the first oil ever to flow in commercial quantities in offshore Ireland."

Early this week, Providence plans to measure the pressure, density and flow rate of the oil, allowing it to plan the number of wells needed to develop the field. O'Reilly said that a very good result for the company would be a flow rate of 1,800 barrels per day.

"We have proven the geological play. But now they are waiting to see if we can flow the oil. The reference points for Irish offshore have always been gas at Kinsale and Corrib. But now people will be able to talk about Irish oil."

O'Reilly was unwilling to predict whether the announcement of a positive flow rate will have a similar impact on the share price as last week's announcement had.

"You would like to think that the market would respond to good news in a positive way. Already last week we put out good news, but we now have to deliver the next step which is the flow rates. Barryroe is the first well in our six-well programme. We always said that any one of these wells coming in would be a game changer for us as a company and it looks like Barryroe is coming in," he said.

O'Reilly believes that success at Barryroe could also be a game changer overall for Irish offshore exploration. He predicts that Ireland, with its huge under-explored acreage, is on the cusp of an exploration boom similar to the one Cove Energy has benefited from in Mozambique.

"I think there are a lot of people watching what is going on offshore Ireland, whether it was news of a big company like Repsol coming in, positive news from the Barryroe well or the fact that Corrib is moving forward."

A big factor is also likely to be high oil prices but Providence's Celtic Sea drilling program is not dependent upon current "ultra high prices", said O'Reilly.

"We did not decide to do what we are doing because the oil price went over $100. Once we saw the oil price comfortably above $40, it really started to make sense for us to look at this whole area. I don't think any company would ever plan their business on these high oil prices. Nobody does. If you were to go to a bank to do financing for oil and gas they would probably give you $65 to $75 a barrel. Most companies would probably see that as the floor so they can consider projects with a rate of return at that level. Nobody would be planning a rate of return based on the current $125 oil price because just as quickly as it goes up it comes back down."
