Petrobras Signs Deal To Explore Shale Oil In Morocco--Sorry, no linky disponible.

RIO DE JANEIRO (Dow Jones)--State-controlled oil firm Petroleo Brasileiro SA (PBR), or Petrobras, has signed a deal to study the extraction of oil from shale rock in Morocco, local newspaper O Globo reported Thursday.

Petrobras and Morocco's Office National des Hydrocarbures et des Mines will sign the cooperation agreement in June when Brazil's president Luiz Inacio Lula da Silva visits Morocco, the newspaper said.

Petrobras already produces about 4,000 barrels a day of oil from shale in the Brazilian southern state of Parana, and has signed a similar agreement with Jordan, O Globo said.

"They have the (shale) rock and we have the technology. It remains to be seen whether it's viable to use it," Bassim Djahjah, Petrobra's manager of new projects in Europe, is quoted as saying.

According to O Globo, Morocco has reserves of 90 billion tons of shale.

Just another way of throwing good money after bad. Oh well, maybe some Morrocans will get good paying jobs out of the deal whuile it lasts.

huge Petrobras deepwater find ?

Unread postby jc4patents » Tue 15 Apr 2008, 13:46:28

what does anyone know about the reported huge deepwater
find reported by Petrobras ? e.g., see initial report at

http://news.yahoo.com/s/ap/20080415/ap_ ... brazil_oil

some estimates say it could be world's 3rd largest reserve

Petrobras also says it could take 5 years to develop the field

There is already a thread here about this.
As an update Petrobras has indicated that although a discovery well was drilled in late 2007 they are not sure of the ultimate size. They spudded a subsequent appraisal well in late March and are still drilling, they have not made it to the reservoir section.
As a consequence the announcement by the Brazil regulatory agency is speculative based on 1. the fact they had a certain amount of reservoir pay in the discovery well that produced hydrocarbon and 2. they have seismic maps that show the areal extent. Without subsequent appraisal drilling they have no idea how extensive the actual reservoir section is. It may not be present over the entire structure or it might thin out in certain areas. Petrobras has also not indicated whether they found an oil/water contact which also is needed to properly assess the potential resources.
An example of a government beaurocrat speaking out of turn.

Hi Rockdoc,

Let's assume they find lots of oil down there. Can you give us some idea on the following:

(1) In an optimistic world, when would they begin producing? I always hear there is about a six year time lag between discovery and production;

(2) From what I've read, the reservoir is about 4k feet deep? I've read under 2k feet of water, 1k feet of salt and another 1k feet of rock. How difficult is this reported reservoir to drill and produce in?

That's a tough question as it depends on a lot of things including rig availability. It looks like it is taking them >60 days to drill and complete but theoretically they could still get most of the field appraised in a rough manner this year. It will likely take 6 months to a year to put together a field development plan and get it approved by the regulatory body although Petrobras would have more clout than others. So that is already 2 years out. Subsea developments in 2 km of water aren't trivial so good comparisons would be the Gulf of Mexico. It looks like from approval of the FDP through to project startup you are looking at least 2-3 years. Given you will likely drill most of your producers before bringing the thing onstream I would be very, very surprised to see anything short of a 2015 - 2016 first oil, assuming the reservoir doesn't turn out to be complex. So my guess it is one of those things that will extend the peak but not actually affect it.
The reservoir actually shouldn't be too problematic assuming the salt is continuous without interbeds of shales and clastics (creates overpressured zones that are hugely problematic in places like the southern Gulf of Suez). The good think about having a salt top seal is it is perfectly impearmeable, whatever oil was migrated into the structure would likely stay there and the formation would hence be filled to spill point. Without knowing much of the specifics of the actual reservoir it is hard to say how difficult it might be to produce as that depends on continuity, quality etc. The presence of significant gas in the reservoir will have a bearing on recovery factor unless there is a strong bottom water drive involved. As you start to produce the oil more and more gas will bubble out as pressure drops. Basically they would need to inject water and/or gas in order to maintain reservoir pressure and keep recoveries high. That would mean more wells and hence further time to development.

I saw two articles about this find today.

One on Yahoo news said this was the big one. Third largest in the world. Yahoo article

$this->bbcode_second_pass_quote('', 'S')AO PAULO, Brazil - 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, a top energy official said Monday.



A few minutes later, I surf over to PO.com, and on the front page is posted an article linked from xinhua.net saying that Petrobas denies the above claim, and they had not finished drilling through the salt layer.
What the f?


$this->bbcode_second_pass_quote('', 'B')razil's Petrobras denies giant oil field discovery


RIO DE JANEIRO, April 14 (Xinhua) -- Brazil's state-owned oil company Petrobras denied Monday an earlier announcement of the discovery of a gigantic oil and gas field in southeastern Brazil.

The salt layer of the second well drilled in block BMS-9 of the announced oil field has not even been reached yet, and the huge field, if it does exist, lies below the salt layer, the company said in a statement.



I know xinhua.net may not be considered to be the most reputable source, but this is strange.

I'll have a side of obfuscation with that!

Yes, they are even throwing a lot of cold water on this 'great' discovery today, "There's nothing concrete in those estimates".

$this->bbcode_second_pass_quote('', 'P')etrobras To Comment On New Oil Find After More Data

DOW JONES NEWSWIRES
April 15, 2008 5:22 p.m.

RIO DE JANEIRO (Dow Jones)--State-run oil company Petroleo Brasileiro SA (PBR), or Petrobras, won't comment further on a new oil find in Brazil's offshore Santos basin until it obtains more concrete data, Jorge Zelada, Petrobras' international director, said Tuesday.

"The first well drilled showed oil, but we need to drill other wells," he said.

Zelada said Petrobras is currently drilling a second well in the area, but it is too early to tell whether that well struck oil.

"We are assessing what needs to be done to evaluate the find," he said.

"There's nothing concrete in those estimates," Petrobras Exploration Director Guilherme Estrella Tuesday told a Senate commission in Brasilia later Tuesday, according to the Estado newswire. "Petrobras works with technical data and concrete estimates."

Credit Suisse, however, cautioned that drilling in the Sugar Loaf area "has been very limited to date," and said that therefore markets may have overreacted to Lima's comments.

Maybe Petrobras doesn't want to count their chickens before they hatch so to speak. They are a publicly traded company and perhaps it would open them up to legal issues of they were trumping a giant oil/gas find when it eventually might not materialize. None the less it should work out to be a sizable discovery even if its only a fraction of the 33 billion barrels possible. Too bad well probably be on the down slope past peak oil once the oil comes online. Even still it would only produce at best what? a few million barrels a day assuming they get plenty of top dollar deep water rigs in there. On a positive note it does appear that the potential for deep water oil discoveries is looking pretty good so far.

There is an article about it in todays Guardian newspaper in the UK. Entitled "Hopes that surprise Brazilian oil discovery could confound the doom-mongers" with an "Explainer: Peak Oil Theory" which does not explain peak oil...

Endless optimism characterises the end of the industrial revolution.

Nevermind:

$this->bbcode_second_pass_quote('', 'B')razil Field Smaller Than Claimed, Credit Suisse Says (Update3)

By Joe Carroll

April 16 (Bloomberg) -- Brazil's Carioca prospect may have 98 percent less crude than a figure cited by the country's oil agency, Credit Suisse Group said, challenging claims that the field is the biggest-ever discovery outside the Middle East.

Haroldo Lima, director of Brazil's National Oil Agency, sent shares of Petroleo Brasileiro SA and other Carioca stakeholders higher when he said April 14 that the offshore field may hold 33 billion barrels of oil. That figure is ``way off the mark,'' Mark Flannery, a Credit Suisse analyst in New York, said today on a conference call with clients.

An estimate of about 600 million barrels ``sounds reasonable,'' Flannery said, adding that the firm isn't yet giving an official assessment of its own. The estimate cited by Lima was probably intended for the entire subsea geological formation known as Sugar Loaf, which encompasses multiple fields, Credit Suisse said.

``A lot of exploration and delineation is going to need to take place,'' Emerson Leite, a Credit Suisse analyst who's been following Petroleo Brasileiro for a decade, said on the conference call. ``We are very early in the process here.''

They're saying Caricoa just by itself might only have 600 million barrels. However, the 33 billion barrel figure cited by Lima was intended for the entire subsea structure known as Sugar Loaf.

In other words, Credit Suisse isn't saying there isn't 33 billion barrels in this formation, they're just saying that the particular sub-structure called "Carioca" isn't the thing that contains 33 billion barrels. The larger meta-structure called "Sugar Loaf" *could* contain that much and is what Lima was referring to.

And BTW, you didn't give the full link.

[...]

"We believe Lima was saying that the whole Sugar Loaf structure might contain 33 billion barrels. That's something we certainly think is possible," he said, explaining that part of the confusion was in the name Carioca, sometimes applied just to the BMS-9 find, and at times to the whole Sugar Loaf area.

Oilfinder,

When do you believe oil production will start in this new area?

What do you believe the recoverable reserves will be in this area?

What do you believe will be the maximum rate of production and when?

Without this find, when do you believe the world will hit peak oil?

With this find, when do you believe the world will hit "peak oil"?
