Pétroles non conventionnels (tight Oil)

Message par energy_isere » 08 nov. 2011, 23:30

L' OPEP à eu une réunion a Vienne ce jour et j' ai pu trouver un papier sur le tight oil dans le monde vu par l' OPEP.

OPEC sees bright but distant future for tight oil

United States, Canada, China seen as main players


LONDON – The world will have to wait at least 10 years before seeing big supplies of tight oil similar to the U.S. shale gas revolution, OPEC said on Tuesday, but reserves of tight oil could eventually rival the conventional oil reserves of Saudi Arabia.

Global reserves of tight oil could be as high as 300 billion barrels, the oil producer group said in a report, well above current estimates of Saudi Arabia’s conventional reserves of around 265 billion barrels.

“Within a decade, it is quite possible that shale oil (tight oil) production could rise at relatively significant levels year-on-year, assuming prices remain well above $60 per barrel, and regions such as Argentina, Australia and Canada do not significantly restrict operations,” the report said.

“Despite widespread shale deposits, it is not yet clear whether the availability of economically viable shale oil is as great as that for shale gas,” OPEC said.

“At present, however, shale oil should not be viewed as anything more than a source of marginal additions,” said OPEC, which produces every third barrel in the world.

Tight oil is a form of light crude oil held in shale deep below the Earth’s surface that is extracted with hydraulic fracturing, or “fracking,” using deep horizontal wells.

Production of tight oil is already transforming the energy industry in parts of the U.S. Midwest and is opening up oil provinces elsewhere, including China.

Unconventional oil developments are dominated by oilsands in the United States and Canada with 2011 global production amounting to 2.3 million barrels per day (bpd) or equal to production of non-OPEC member Norway.

OPEC said global output of non-conventional oil would rise to 3.4 million bpd by 2015, still dominated by oilsands, to 5.8 million bpd by 2025 and to 8.4 million bpd by 2035 when tight oil would be playing a much bigger role.

Even by 2035, the United States and Canada would continue to dominate the league of unconventional oil producers with 6.6 million bpd and China would also emerge as a major player with output of 1.1 million bpd
.

OPEC’s estimates are based on a recovery rate for tight oil of just three per cent. The recovery factor for conventional oil stands above 50 per cent.

FROM TEXAS TO PARIS

Greater use of unconventional sources of energy has the potential to redraw the global energy map as developments in such technology as hydraulic fracturing boost the potential resource’s outlook.

Like shale gas, tight oil developments will also probably draw criticism from environmentalists and politicians over concerns about water poisoning and seismic activities as a result of exploration.

OPEC said known tight oil resources cover several basins including in the United States (Bakken, Eagle Ford, Niobrara, Utica, Leonard Avalon, Woodford and Monterey), Beetaloo in Australia, Exshaw and Macasty in Canada, Paris in France and Vaca Muerta in Argentina.

“To date, only the Bakken oil shale formation in North Dakota and Eagle Ford in Texas have been exploited for a sufficient period of time to have a clear understanding of actual resources and reserves,” the report said.

“A number of other deposits are being targeted, but given that many are in their infancy, data on the resources in place and the estimated recoverable reserves is generally limited, and beset with uncertainties,” it added.

“Development costs for shale oil appear to be roughly in the $30-$80 per barrel range, excluding taxes and royalties. However, as the industry develops and moves further along the learning curve, costs can be expected to come down, perhaps sharply over the medium term, before flattening out,” OPEC said.

ExxonMobil Eyes Massive Siberian Shale Reserves

June 05, 2012 rigzone

Exxon Mobil Corp. is starting work with Russia's OAO Rosneft in assessing what could be massive reserves of shale oil in Western Siberia, the U.S. giant's Chief Executive Rex Tillerson said Tuesday.

"There is huge shale potential in shale rocks in West Siberia...we just don't know what the quality is," Mr. Tillerson said in an interview with Dow Jones Newswires.

The exploration work will take years to establish if the reserves are commercially viable, and are part of a strategic agreement Exxon reached earlier this year with state-controlled Rosneft, Russia's largest oil producer.

"Rosneft wished to participate in some resource development opportunities outside of Russia and we have invited them to farm into some areas in Canada and in Texas, in tight oil," Mr. Tillerson said, adding the agreement also called for Exxon to also help evaluate similar tight resources opportunities in Western Siberia.

Tight oil is mostly, but not exclusively, oil trapped in shale rock formations that requires advanced fracturing technology to release.

"The shales are basically the source rocks for conventional production in the region and anywhere you have large existing conventional production you are going to find source rocks," he said.

Shale Play in Siberia 80X Bigger than Bakken

OilPrice.com June 05, 2012

"The Bakken shale play is one of the biggest in the U.S., but is absolutely dwarfed by a shale play in Russia. The Bazhenov is located in Western Siberia, and according to Oswals Clint, Sanford Bernstein’s lead international oil analyst, it “covers 2.3 million square kilometers or 570 million acres, which is the size of Texas and the Gulf of Mexico combined;” an area 80 times bigger than the Bakken.

News of the Bazhenov may be new to many of us, but geologists have actually been studying it for at least 20 years, however it is only in the last few years that the technology and expertise necessary to drill the oil has been developed.

ExxonMobil and Statoil have agreed to start joint venture operations in the region with the Russian, state-owned Rosneft in an attempt to secure access to the Bazhenov. Exxon made a recent statement which confirmed the agreement “to jointly develop tight oil production technologies in Western Siberia.”

Russian shale oil play could be 80 times larger than North Dakota’s Bakken, says Forbes

But as great as the Bakken is, Forbes writer Christopher Helman says the Bazhenov shale oil play in Western Siberia could be many times larger.

“According to a report last week by Sanford Bernstein’s lead international oil analyst Oswald Clint (the Bazhenov) ‘covers 2.3 million square kilometers or 570 million acres, which is the size of Texas and the Gulf of Mexico combined.’ This is 80 times bigger than the Bakken,” says Helman.

Getting access to the Bazhenov appears to be a key reason why U.S. giant ExxonMobil and Norway’s Statoil have forged joint ventures with Rosneft, Russia’s state-controlled energy giant.

“Analyst Clint figures that it won’t be hard for Big Oil to export their shale-cracking techniques to Siberia . . . If Russia can get its act together to deploy 300 drilling rigs to the play, Clint figures Bazhenov could be producing one million bpd by 2020,” says Helman.

une carte de la formation de Bazhenov :

extrait de ce pdf : http://energy.cr.usgs.gov/WEcont/region ... 117412.pdf
DESCRIPTION: This unconventional assessment unit includes fractured Bazhenov siliceous
shales, which are also source rocks for these reservoirs. The shales cover most of the basin, but
their productivity has been demonstrated mainly in the Greater Salym area. In-place resources of
oil are apparently very large, but the ability of the reservoir rocks to produce varies greatly and is
poorly understood. There is much similarity between this unit and the Bakken play of the
Williston basin.


SOURCE ROCKS: Source rocks are deep-marine siliceous and calcareous shales and siliciliths
of the Volgian-lower Berriasian Bazhenov Formation. The formation is 20 to 50 m thick and
contains 5 to 20 percent TOC. The kerogen is of Type II.
Dans un autre document pdf de l' USGS : http://pubs.usgs.gov/bul/2201/G/B2201-G.pdf
on voit en page 25 et 26 que cette formation est pas trés épaisse (une cinquantaine de métres d 'épaisseur au plus) et recoupe géographiquement avec du pétrole conventionnel en de trés nombreux endroits.

The formation feeds conventional oil fields. Those conventional oilfields have over 144 billion barrels of oil. There have been some wells drilled into the Bazhenov tight oil area and those are producing 400 barrels of oil per day, which is similar to the productivity of Bakken oil wells.

Russia has the potential to develop the Bazhenov Formation to remain and energy superpower for another 100 years.

Meet The Oil Shale Eighty Times Bigger Than The Bakken

Forbes June 04, 2012

Everyone has heard about the Bakken shale, the huge expanse of oil-bearing rock underneath North Dakota and Montana that billionaire Harold Hamm thinks could yield 24 billion barrels of oil in the decades to come. The Bakken is a huge boon, both to the economic health of the northern Plains states, but also to the petroleum balance of the United States. From just 60,000 barrels per day five years ago, the Bakken is now giving up 500,000 bpd, with 210,000 bpd of that coming on in just the past year. Given the availability of enough rigs to drill it and crews to frack it, there’s no reason why the Bakken couldn’t be producing more than 1 million bpd by the end of the decade, a level that could be maintained for halfway through the century.

But as great as the Bakken is, I learned last week about another oil shale play that dwarfs it. It’s called The Bazhenov. It’s in Western Siberia, in Russia. And while the Bakken is big, the Bazhenov — according to a report last week by Sanford Bernstein’s lead international oil analyst Oswald Clint — “covers 2.3 million square kilometers or 570 million acres, which is the size of Texas and the Gulf of Mexico combined.” This is 80 times bigger than the Bakken.

Getting access to the Bazhenov appears to be a key element in both ExxonMobil and Statoil‘s big new joint ventures with Kremlin-controlled Rosneft. Exxon’s recent statement says the two companies have agreed “to jointly develop tight oil production technologies in Western Siberia.”

No wonder. The geology of the Bazhenov looks just as good if not better. Its pay zone averages about 100 feet thick, and as Clint points out, the Bazhenov has lots of cracks and fractures that could make its oil flow more readily. The couple of test wells that he cites flowed at an average of 400 barrels per day. That’s in line with the Bakken average.

This Siberian bonanza might be news to most of us, but it’s old news to Big Oil. The conventional oil fields of Siberia have been producing millions of barrels a day for decades — oil that originated in the Bazhenov “source rock” then slowly oozed up over the millenia. From the looks of it, geologists have been looking at the Bazhenov for more than 20 years.

It’s only in the last five years that the technology and expertise has been developed that will enable drillers to harvest it. Lukoil‘s president Vagit Alekperov said a year ago that his company was also experimenting with the shale.

Analyst Clint figures that it won’t be hard for Big Oil to export their shale-cracking techniques to Siberia. They will be challenged, however by summer weather in Siberia, which softens the ground enough to prevent drilling for much of the season. If Russia can get its act together to deploy 300 drilling rigs to the play, Clint figures Bazhenov could be producing 1 million bpd by 2020.

This would, of course, have huge geopolitical implications. Russia, though it doesn’t have as many proved reserves as Saudi Arabia, had been outproducing the Saudis for years, averaging about 10 million bpd to Saudi’s 9 million bpd. This year, the Saudis are said to have surpassed Russia, leading some pundits to speculate that Russian oil supply had peaked and was set to begin spiralling down.

Developing the Bazhenov could reverse that decline. Unlike the Kremlin’s much ballyhooed plan to drill for oil in ice-packed Arctic waters, the beauty of the Bazhenov is that it is onshore and it underlies an area that is already criss-crossed with pipelines serving mature, conventional fields. No need for expensive icebreakers, cold-weather drillships and subsea pipelines.

If Harold Hamm is convinced the Bakken will give up 24 billion barrels, a play 80 times bigger like the Bazhenov would imply 1,920 billion barrels. That’s a preposterous figure, enough oil to satisfy all of current global demand for 64 years, or to do 5 million bpd for more than 1,000 years. Rosneft, says Clint, has already estimated 18 billion barrels on its Bazhenov acreage. Either way, it looks like they’ll still be working the Bazhenov long after Vladimir Putin has finally retired and the Peak Oil crowd realizes there’s more oil out there than we’ve ever imagined.

Exxon to back Rosneft's Siberian search for 'tight' oil

Fri Jun 15, 2012

* Rosneft sees unconventional output potential at 300,000 bpd

* Companies expand 'tight oil' deal to work in Siberia

* Sechin emphasises drilling in strategy speech

* Putin ally to chair oil advisory committee

By Vladimir Soldatkin and Melissa Akin

TUAPSE, Russia, June 15 (Reuters) - Rosneft advanced an alliance with U.S. major ExxonMobil on Friday that will help finance a push by Russia's top oil producer to drill in Siberia for tight oil - - oil held in non-porous rock which cannot be extracted by conventional drilling.

With ExxonMobil's chief executive on hand, the state oil company's head Igor Sechin presented a Rosneft strategy paper to President Vladimir Putin that envisaged 300,000 barrels per day of potential production from unconventional reserves in Siberia.

ExxonMobil will bear the cost of financing some exploratory drilling, to start in 2013, under an agreement signed by top executives from Rosneft and Exxon, advancing an exploration partnership centred on the promising but challenging Russian Arctic.

Their initial exploration agreement - followed by similar exploration pacts with Eni and Statoil - established Sechin as the oil industry's top dealmaker. It set him up to move to Rosneft from his previous role at deputy prime minister responsible for energy in the government Putin headed as prime minister.

His leading political role in the industry was reaffirmed on Wednesday when Putin made him the secretary general of a committee on oil industry development and the environment following an informal gathering of an "oilman's club" at Rosneft earlier this month. Putin will chair the committee himself.

Together with Sechin's appointment, Rosneft's ambitious plans signal the importance of the state oil company to the Kremlin which relies on it not only to guarantee Russia's lead in world oil output, but to make much needed investments in refining to ensure stable fuel supplies and bring in revenue.

Putin called on Sechin to boost Rosneft's dividend payout, saying it would benefit the government.

"As I understand it, this decision, if it is approved by shareholders, would help the company's market value to rise, which is only in the interests of the government," Putin told Sechin.

Unlike Saudi Arabia, its nearest rival for the title of world's top oil producer, Russia has little spare capacity and the government is struggling to balance its dependence on oil revenues with the need for tax cuts to stimulate output.

But in his final weeks as prime minister before returning to the Kremlin as president Putin announced some tax concessions to encourage drilling in tight formations, saying the boost to Russia's output could be 1-2 million barrels per day.

Rosneft says it has 1.2 billion barrels of tight reserves in its licensed territory, though not all of its licences allow it to drill to those depths.

Sechin, presenting Rosneft's strategy, said Rosneft would ramp up its drilling programme to help the company maintain and expand its position as the holder of the world's largest liquid hydrocarbon reserves.

Additional exploration could double the reserves of Vankor, one of Rosneft's prize fields, which will raise production to 500,000 barrels per day to ensure Rosneft's output continues to grow from the current level of about 2.2 million barrels per day, nearly a quarter of Russia's output.

"Vankor's recoverable reserves will be about 1.1 billion tonnes," Sechin said. Current reserves are 432 million tonnes.

It will also expand the drilling of horizontal wells with multi-stage hydraulic fractures, similar to the technology used in U.S. shale fields to tap tight rock formations after encouraging results from such wells drilled last year.

It plans to drill 100 similar wells in 2012-14, it said.

Pétrole de Schiste : les Argentins s'y mettent !

Au rythme auquel s'y convertissent les différents pays de la planète, nous allons bientôt être les seuls à refuser encore l'exploitation des gaz (et pétrole) de schistes voire même la seule expérimentation de la technique d'extraction !

Le dernier en date est l'Argentine, dont le pétrolier national, YPF, Yacimientos pétroliféros argentinos / Gisements pétrolifères argentins, vient d'annoncer un accord avec l'américain Chevron pour exploiter le pétrole de schiste de l’extrême sud de la péninsule argentine, dit le gisement de la Vaca Muerta, la Vache Morte. Un gisement dont on estime qu'il pourrait contenir 23 milliards de barils.

D'autres discussions sont en cours avec ExxonMobil et Apache pour augmenter la production d'hydrocarbures du pays de 32 % d'içi 2015. Un soucis majeur pour les autorités d'accroitre les ressources pétrolières du pays pour si possible supprimer les importations qui grèvent lourdement la balance des paiements du pays. Une contrainte si forte qu'elle a conduit le pays et sa Présidente à éjecter cavalièrement l'espagnol Repsol du capital de YPF. Ce dernier était accusé de ne pas investir suffisamment dans le pays, de même que le français Total qui, lui, a su éviter l'orage.

YPF manque néanmoins du savoir faire technique pour exploiter de tels gisements et d'argent depuis qu'il a été nationalisé pour en éjecter Repsol. D'où l'appel aux sociétés américaines qui ne se pressent pas pour autant au portillon après l'expropriation de Repsol et face au style de management cavalier pour le moins de la Présidente. EIle prévoit d'investir par moins de 37 milliards de dollars sur 5 ans dans l’extrême sud et d'y créer 10.000 postes supplémentaires.

Dernier élément de reprise en main par le pouvoir de sa compagnie nationale. La politique de dividende de YPF, autrefois généreuse à 90% des bénéfices, a été annoncée avoir été modifiée désormais à seulement 5% de ce bénéfice redistribué ! Investisseurs, faites attention, l'Argentine reste une zone de non droit.

page sur le sujet : http://vacamuertashale.com/companies.html

et aussi :
The Vaca Muerta formation located in Neuquén Province in Argentina is supposed to be one of the largest shale formations outside of North America. The discovery was made by Repsol-YPF, but with Argentina's recent move to nationalize YPF, it leaves the door open for foreign investors, possibly governments, to partner with YPF and help develop the resource.

Here's what we know about the Vaca Muerta formation so far:

The Vaca Muerta formation covers a total area of 30,000 square kilometers (km2) or 7.4 million acres.

Image

The discovery has the potential to increase Argentine hydrocarbon production by 50 percent by 2019 according to YPF estimates.
The field needs investment of up to $42 billion to increase production by 50 percent and will be split at $28 billion for oil production and $14 billion for gas production.
Initial exploration efforts suggest that there are 927 million barrels of oil equivalent in non-conventional hydrocarbons. An independent study by Ryder Scott, an oil and gas consulting firm confirmed that the Vaca Muerta oil and shale gas formation has more than 21 billion barrels of oil equivalent (BOE).
Argentina relies on natural gas to meet 51 percent of its energy needs, and natural gas was also one of the most significant facets of its energy trade deficit in 2011, according to Morgan Stanley analyst Paolo Batori. Vaca Muerta has the potential to make Argentina a net exporter of energy.

Premiers échantillons de shale Oil extraits au japon.
A Japanese drilling company says it has succeeded in extracting shale oil from underground in Japan for the first time. Shale oil is attracting attention as a new energy resource.

Oct. 3, 2012 -

The Japan Petroleum Exploration Company said on Wednesday it is extracting small amounts of shale oil mixed with acid from the Ayukawa oil and gas field in Akita Prefecture, northeastern Japan.

Black crude oil separated from the acid in a flask was shown to the media.

Shale oil is contained in hard rock layers deep underground. Recent advances in drilling technology have made development possible.

The company began Japan's first test production of shale oil on Monday.

Engineers pumped in acid to dissolve the hard bedrock about 1,800 meters below ground and began the extraction process on Tuesday.

The test will continue until Thursday. The company says it will study the amount and speed of extraction to see whether production can generate a profit.

Company officials say Akita Prefecture could produce up to 100 million barrels of shale oil. That's the equivalent of nearly 10 percent of annual crude oil consumption in Japan.

Huile de schiste Statoil achète des champs américains pour 590 millions

19 Dec 2012

La compagnie pétrolière norvégienne Statoil a annoncé mercredi l'achat de 590 millions de dollars de champs d'exploitation d'huiles de schiste aux Etats-Unis.

Statoil a indiqué dans un communiqué avoir mis la main sur 283 km2 de champs exploités dans la formation de schiste Marcellus, dans les Etats de l'Ohio (Nord) et de la Virginie Occidentale (Est), qui produisent aujourd'hui quelque 5.000 barils équivalent pétrole par jour.

Les vendeurs sont trois groupes américains spécialisés dans les actifs pétroliers: Grenadier Energy Partners, Protégé Energy II et Petroedge. La transaction, en numéraire, a été bouclée mardi.

Statoil est présent dans cette formation de schiste depuis 2008 via une coentreprise avec le gazier américain Chesapeake. "Depuis, le groupe a mené une stratégie de croissance ciblée et graduelle, pour étendre ses actifs à l'intérieur des terres aux Etats-Unis", a rappelé le norvégien.

Il a rappelé son entrée dans les champs Eagle Ford (Texas) en 2010 et Bakken (Montana et Dakota du Nord) en 2011.

L'huile de schiste, hydrocarbure dit non conventionnel, permet d'extraire dans le cas de Marcellus du gaz sous forme liquide.

Statoil a estimé entre 300 et 500 millions de barils équivalent pétrole les réserves dans les champs acquis. Il a indiqué qu'il voyait un "potentiel important de montée en puissance" de la production.

Statoil avait fait un pas important dans l'exploitation du pétrole et gaz de schiste aux Etats-Unis en annonçant en octobre 2011 le rachat de l'américain Brigham Exploration Company.

Gazprom Neft débute son premier forage de son programme de développement de pétrole non conventionnel. Localisé en Sibérie.
Gazprom Begins New Tight Oil Project

January 11, 2013 MOSCOW

OAO Gazprom Neft, the oil arm of state-controlled gas giant OAO Gazprom, has begun drilling an appraisal well as part of its program to develop unconventional and hard-to-recover oil reserves, the company said in a statement Friday.

The drilling at the Krasnoleninsky deposit in the Khanty-Mansi Autonomous District in Siberia will help Gazprom Neft "improve tight oil expertise in order to develop hydrocarbons located in the Bazhenov, Abalakskaya and Frolovskaya formations," the company said. It will examine the reults of drilling in spring this year then decide on further project development.

Oil companies in Russia – the world's top energy producer – are increasingly looking to deposits that are harder to tap as production declines at Soviet-era fields in Western Siberia.

Gazprom Neft is already working on a similar tight oil project with Royal Dutch Shell. In December, state-controlled oil giant OAO Rosneft and Exxon Mobil Corp. signed a deal for a pilot drilling program to assess tight oil reserves.

l' EIA annonce des chiffres de shale oil dans le monde. La Russie serait en téte des ''reserves'' grace au champs de Bazhenov.

Russia sits on largest reserves of shale oil
...............

he EIA estimates the total reserves of shale oil at 375 billion barrels, of which Russia accounts for 75 billion, the U.S. 58 billion and China 32 billion.
U.S. experts believe that nearly all Russia's shale oil resources are contained in the oil-bearing deposits of the Bazhenov play in Western Siberia, pointing out that they are hard to reach: The amount of recoverable reserves represent only a fraction (6 percent) of the total (1.24 trillion barrels), even ignoring the economic feasibility of producing them.
In the coming years, Lukoil, Rosneft (together with ExxonMobil), and Gazprom (together with Shell) plan to commence experimental development. In contrast, thanks to the widespread application of hydraulic fracking and horizontal drilling, shale oil in the U.S. already makes up 30 percent of total production. It is shale that helped keep oil prices in the region of $120 per barrel during the period of sanctions against Iraq.
