Caspian Oil – A Sunday Special

Oil & gas in the Caspian has a long history – indeed it is one of the earliest oil production regions in the world, with Baku a major oil center in the second half of the 19th century and beyond. What makes the situation today interesting is the simultaneuous appearence of three things: (i) new reserves disovered offshore, (ii) the fact that, with the break up of the Soviet Union, the oil is located in (new) countries that  are keen to have foreign investment and (iii) these countries have no direct access to the world markets.

“Caspian energy” actually covers 3 different things:

It is this new sector that has created the hype around the Caspian and its new reserves, because it is one of the few areas in the world where big fields have been discovered in recent years. The excitement in big oil companies is real, because the province is probably the size on the North Sea AND it is accessible to them. Being the size of the North Sea only, it will not change the oil balance of the world either – it will account at most for 3-5% of world production at its peak, in 5 to 10 years.

I have some good news: Caspian oil is actually fairly simple to understand because there are only 5 hydrocarbon fields worth noting, and a couple of pipelines. So here they are:

(table from EIA, same link as above)

(1) ACG (formerly, AIOC)
That’s the big oil field just offshore of Baku in the Azerbaijan sector of the Caspain Sea. It is currently the only field in Azerbaijan with proven oil reserves, despite massive exploration campaigns in the past 10 years. It is currently being developed by a Western consortium led by BP (which includes Unocal, Devon, Amerada-Hess and ExxonMobil of the USA as well as a number of other companies ), under a contract signed in 1994 (and which is public, you can download it here, along with a ton of other documents on the project). It has an estimated 5 to 7 billion barrels of recoverable oil  (slightly less than what is hoped to be found in ANWR, to give you an idea). It has been producing small volumes, about 100 to 150,000 b/d,  since 1998, which are exported by a small pipeline going to Georgia, the Baku Supsa. (They also have the right to use the Baku-Novorossisk pipeline going through Russia).
Big investment is underway to bring production to between 800 and 1,000,000 b/d in the next couple of years. Whan I say big investment, I mean big: about 12 billion dollars will  have been spent by 2010. Most of that oil will use a new pipeline, the BTC (see below) which is currently being built.

(2) Shah-Deniz. It’s a big mostly gas field offshore Azerbaijan. It is actually the only significant discovery of hydrocarbons in the Azeri sector, but it is gas, which was not the best of news for the oil companies, as the markets are very, very far away. The consortium is also led by BP (with Total, Statoil of Norway, TPAO of Turkey and OIEC of Iran) and it has managed to go ahead with the development of the project by signing a contract for the gas with Turkey (although there are doubts about Turkey’s need for that gas). BP has agreed to build a gas pipeline in parallel to the BTC oil pipeline to bring the gas to Turkey, and they are now hoping to build new pipelines form Turkey to centrla Europe to be able to give more value to that gas (that project is still in its early phase, you can find more details by clicking on this link which refers to its codename: Nabucco (pdf, 280 kb), which includes this map:).

(3) Tengiz
A big onshore oil field in Kazakhstan – one of the biggest in the world, developped by a consortium led by ChevronTexaco (and including ExxonMobil, Lukoil and ENI of Italy), with about 9 billion barrels of recoverable reserves (another ANWR). Although Chevron came in in 1993, they have had a really hard time with that field, as they had no way to export the oil anywhare. They have used amazing ingenuity to sell their oil (including owning most of the railcars of the former Soviet Union – about 9,000, to sell their crude by rail, or sending barges all the way to Finland by the canals of Russia) but this has seriously limited the production of the field. Now that the CPC pipeline has finally been built (see below), they are finally ramping up production, which is expected to reach  700,000 b/d in a fews years.

(4)Kashagan
The biggest oil field to be discovered in the past 30 years, it is in the North of the Caspian Sea, in the Kazakh sector (see a detailed map here), and it is being developped by a consortium including all the big majors (ExxonMobil, Shell, Total, ConocoPhillips, ENI, BG and Inpex, with ENI, the Italian group, as the operator (Exxon did not want Shell, Shell did not want Exxon, and ENI was smarter than Total to be voted in…). With 9-15 billion barrels of reserves (exploration is not totally complete), it is yet another ANWR fully in control of BigOil, but it is very challenging technically (very high pressures, located in an areas which is at times seawater, ice, mud or any combination in between, and far away from any transport infrastructure in an area with a very tough climate) and it will need to find export routes for its production (a combination of CPC and BTC is likely to start with)

(See here for a larger version with full explanations)

(5)Karachaganak
A big, mostly gas field in North Kazakhstan near the border with Russia, it is being developped by ENI, BG, ChevronTexaco and Lukoil. As a gas field, it is heavily dependent on Russian gas monopoly Gazprom (the gas is currently being processed at the nearby Orenburg Gazprom plant), but the consortium is strong enough to negotiate decent terms and to buld its own infrasturcture. As the field contains both gas and liquids (i.e. good quality oil) which have to be produced together, the consortium has focused on selling the oil on the world markets and selling the gas at a low price to Gazprom. The oil will go into the CPC pipeline.

So this bring us to the pipelines. There are a number of existing ones, most of which go through Russia and are thus considered  by the oil majors – with reason – as unreliable. They have thus made a lot of efforts to find new routes.
A simple solution would have been to ship oil to Northern Iran (where Iran’s refineries are) and swap it for Iranian oil produced in the south of the country. This made good sense for Iran, which would not have needed to ship its own oil for the production in the South to its refineries in the North, but it is not possible under the current US sanctions regime (ILSA). This solution would be partial anyway as the capacity of the Iranian refineries is no more than 800,000 b/d and they would have needed significant investment to ba able to use the Caspian crude qualities.
So with Russia and Iran out, this left only the Western (and at a later point Easter to China) routes. An additional problem is that of the Bosphorus, which already sees a significant volume of oil tanker traffic, which the Turkish authorities were keen to not see increase. Bringing in an additional million barrel per day or two into the Black Sea (on the coast of Georgia for instance) would have created a real danger for Istanbul and this was thus stronly opposed.

Thus came to birth the BTC, which goes West from Azerbaijan, through Georgia, and then South through Turkey to the Mediterranean. It is being built by a consortium led, again,  by BP (which, interestingly, is different from either the ACG consortium and the Shah-Deniz consortium)

You can find a massive quantity of information on the project starting from here, but the main thing to know is that it will have a capacity of 1,000,000 b/d, a good chunk of which will be used by ACG oil to start with, and all the liquids Shah-Deniz can produce. It is currently being built and is expected to come into service by the end of this year. It has cost 3-3.5 billion dollars to build, more than half of which was financed by international banks with the participation of the World Bank and the EBRD.

You’ve probably heard nasty things about the project because it has been used as a target by a number of NGOs that absolutely want the World Bank to stop financing the energy sector, and they tried to show that such projects were tremendously damaging to the environment and to the local populations. They’ve put pressure on the World Bank, on the commercial banks and on the oil companies, thankfully to no avail (this is not the topic here, but I do intend to write more about this and explain that “thankfully”. In the meantime, you can go see the envirionmental reports on the BTC site linked to above, and otherwise google “Extractive Industries Review” or “Equator Principles”)

The other big pipeline in the region is the CPC (Caspian Pipeline Consortium) which, as you can see on the maps above, does go through Russia and does bring oil into the Black Sea. It nevertheless has the particularity of being the only privately owned pipeline on the territory of Russia (something that they really don’t like and are trying to undermine at every turn, especially these days as an extension is being discussed). It was built (and paid for) by a consortium led by ChevronTexaco, and currently has a capacity of 450,000 b/d, due to be increased to 1,300,000 b/d. It is used for oil from Tengiz and soon from Karachaganak.

So, what can be learnt from that?

Again:

There is a lot more to write on the topic; I am not avoiding any topic and would be pleased to provide more info in the comments at your request.
