OGPSS - Lower second tier oil producers - Norway, Brazil, Iraq and Algeria

This current series of posts is aimed at an overview of the top oil producing nations, seeking to establish how the ranking of the countries is changing from the original table that EIA put out in 2008, After looking at the conditions governing the top six, this was followed last week when I looked at the condition of the following three (Mexico, UAE and Kuwait) in a little detail, but, having spent four posts on Veneuela in the recent past forebore going back there again.

It is worth recapping, however, that the initial order has changed, and that, currently Russia is at the head of the League, slightly ahead of Saudi Arabia., and both producing somewhere around 10.2 mbd. I’ll go more into that detail as the posts focus in on the individual countries later. The United States production, if one includes ethanol, is around 8.2 mbd, and this is in third place,. China has moved into fourth place, slightly ahead of Iran which is followed by Canada. At present these six appear to be the only countries producing over 3 mbd.

In the next tier down I have already mentioned the United Arab Emirates, which have moved into 7th place, with a production of around 2.81 mbd, how ahead of Mexico, albeit perhaps barely (based on the addition of NGLs etc). As with the UAE Kuwait has been limiting production in line with OPEC requests, but while only producting at around 2.35 mbd at the moment, is looking to increase this to up to 3.5 mdb by 2015, which would move it into the top tier. Venezuela, although it too has some grandiose plans, based on the potential increases in production from their tar sands, is currently producing at down around 2.26 mbd. As I have mentioned Venezuela does have plans to raise production to 4 mbd by 2015. However recent commitments to China of up to 1 mbd and problems that Venezuela continues to have in meeting current obligations leaves a large question mark on those predictions.

And so we come to the lower half of the second tier.

In order to create the current ranking we have to first work out what the current levels of production are, and the future potential. So let’s start with Norway, since that country did rank 11th in 2008. Statoil has noted that their equity liquids production fell to 1.945 mbdoe in the fourth quarter of 2010. Statoil anticipate that there will be little change in production this year, but that there may be a slight rise thereafter. Statoil is not, however, Norway, being responsible for about 80% of the countries production (with properties abroad as well) but I mention it as indicative of the trends. One hopeful sign of which been the agreement with Russia that defines who owns what in the Barents Sea. However when we look at the long-term Norwegian trend is is recognizably downwards, with the Norwegian Petroleum Directorate predicting a 1.7 mbd average production in 2011. The Directorate is predicting that oil production will fall to 1.54 mbd by 2015. This does not consider other liquids and if these are included, while the overall total still lies below 2 mbd, it is currently a lot closer to that, though that is not expected to last.

Norwegian oil production in 2011 (Norwegian Petroleum Directorate)

In January this total, was made up of 1.836 mbd of crude oil, 256 kbd of NGLs and 69 kbd of condensate. Most of Norwegian production is exported, and the percentage can be seen from the EIA Country Analysis. The relatively flat domestic production is (as we have discussed with the Export Land Model) not typical.

Declining production, and thus exports of petroleum from Norway (EIA )

Natural gas production, on the other hand, is continuing to rise, though it depends on finding and developing new fields, and 95% of this is exported.


Norway produced 3.65 Tcf in 2009, with the majority of production coming from the Troll, Oman Lange and Asgard fields.

The next country down the 2008 list was Brazil, and here there is a change in order since Brazil is now rising past 2.12 mbd of crude production in December, moving ahead of Norway. Offshore production in the Tupi field, which may hold 6.5 billion barrels of oil, will be followed by that from the Jupiter field, possibly of similar size. The fields fall deep offshore in the Santos and Campos Basins, which will deserve a couple of posts on their own, down the road.

Development has now started.

The Tupi field is being developed as a pilot project in two phases. In the first phase tests will be conducted to gather information about the future production systems. This phase is expected to end in 2012.

The second phase is expected to start from 2012 and will include two parts. In the first part (2012-17) ten production units will be installed at the field with 20 producing wells and injectors expected to be drilled during this time.

In the second part of phase two (after 2017), new technologies such as dry completion units will be employed to recover oil and natural gas from the field.

Brazil plans to double crude production from the current 2 mbd to 4 mbd by 2020, reaching 3 mbd by around 2014. However overall liquids production is already at 2.7 mbd and the EIA anticipates that this will rise over 3 mbd by next year. With the cumulative liquid totals Brazil has also passed Venezuelan production and may soon be competing with Kuwait as they both move into the top tier.

Brazil also produces ethanol, mainly from sugar cane, with production at around 450 kbd However, with a growing economy, the country does not, as yet, have much of its production available for export. (The BP figures are a little more pessimistic than those of the EIA).

Brazilian oil information (Energy Export Databrowser)

Brazil continues to find oil onshore, most recently in the Amazon Basin and this bodes well for the targets that it now envisages.

Brazil gets most of its electric power from hydro-electric power plants, but is able to use the natural gas that is recovered during oil production to meet about half of the national need for gas, the rest being imported.

The next country on the original list was Iraq. And this poses a problem of prediction since we have to decide who to believe in the tales of competing numbers that have been used, among other places by BP in predicting the sources of future oil supply. The problems in this case are as much geo-political and locally ethnic and religious as they have to do with the capabilities of producing oil. At the moment Iraq has finally got back up to a production level of 2.6 mbd not that this will necessarily help Western imports that much:

The rising output will boost Iraq’s oil exports by 5 percent to 2 million barrels a day next month, Falah al-Amri, head of the country’s State Oil Marketing Organization, said today in an interview in Baghdad. The nation sells about 60 percent of supplies to India, China and other Asian countries where demand is increasing, he said

In January, OPEC reports, Iraq produced a total of 2.7 mbd, which was 300 kbd up on production in the last quarter of 2010. To put this in context in February 2003, just before the conflict began, Iraq was producing 2.8 mbd. At the moment production is centered on the North and South Ramalla fields and that of Kirkuk in the North. The problems of Iraq are not so much, in the short term those of most of the rest of the world, i.e. in finding more oil. In the immediate short term the information on fields that have been known for some time (and in some cases were previously producing) already exists. What is needed is some way of ensuring that the infrastructure is repaired and, if necessary, new pipelines laid. Those plans are now advancing although it is now going to be more difficult to foresee their short-term success, given the developing turmoil in the region. The EIA has posted a table showing the potential from the different regions.

Estimate of oil availability in Iraq

Consumption in Iraq has been fairly stable until about 2007 where it started to climb, and, given a little more stability in the country, it is reasonable to expect that it will surge as it has in much of the Middle East. On the other hand it is a little difficult for me to see production rising to the 12 mbd figures that are now discussed as being possible for Iraq by 2017.

Until recently Iraq was flaring more than 60% of the natural gas that it was producing (perhaps as much as 1 bcf/day) One option that is open is to pipeline some of the gas up to Turkey and then feed it into the Nabucco pipeline. There is a hope that this can lead to exports of up to 2.5 bcf/day but new legal hurdles are continuing to delay progress. Apart from resurrecting the pipelines there is also the possibility of installing an LNG train or two.

And when one is considering the growing instability of the region, the next country down the list is Algeria, and that has now started to be mentioned among the countries feeling the fallout from the initial protests in Tunisia. The Algerian Foreign Minister is denying the risk of a “domino” effect. Possibly this could be because, as it is reported the income from oil and gas sales can, in this case help.

Unrest in Algeria could have implications on the world economy since it is a major oil and gas exporter, but analysts say an Egypt-style revolt is unlikely because the government can use its energy wealth to placate most grievances.

There are, however, other opinions.

Algeria is a member of OPEC, which reports the January 2011 production of oil at 1.28 mbd, which has been relatively stable for some time. The EIA consider that the crude is some of the finest in the world . Production is supplemented by condensate (450 kbd in 2008) and NGL (357 kbd) for a total liquid fuels production of over 2 mbd. It is the largest oil-liquids producer in the African continent.

Algeria, which operates the oil and gas through the company Sonatrach exports most of its natural gas, through pipelines to Europe and through LNG terminals, with a new one that is to be completed in 2012. Total exports are around 2 TCF making it the fourth largest exporter. (CIA 2011 World Factbook). Gazprom has recently become involved in field development. It also provides a useful fuel for the processing of fertilizer in Morocco, as Jeff Vail noted, back in 2008. As one of the world’s largest exporters of natural gas, Algeria supplies Southern Europe.

The part of the Algerian gas in the gas balances in some European countries is significant. 86% for Portugal, 61% for Spain, 49% for Italy, 26% for Belgium, 25% for France and 21% for Turkey. Today about 97% of Algerian gas exports supply the European market next to Russia, and Norway, one of the main suppliers of the Europe. Algeria accounts for 29 percent of European Union gas imports and 15% of gas consumption

The Algerian reserves are found in the Sahara

• 67% of oil and gas reserves contained in the Oued Mya and HassiMessaoud areas, where the two giant fields Of Hassi Rmel (Gas) and Hassi Messaoud (Oil) are located. 

• The Illizi basin comes third with 14% of initial reserves;

Then come the basins of Rhourd Nouss (9%), Ahnet Timimoun (4%), and the Berkine basin.

Algeria is hoping to increase exports by 50% by 2015, using a new pipeline into Spain to help develop the European market.

But the current turmoil may make some of these plans moot.

OGPSS-When oil isn’t crude and gas isn’t gas, the Eagle Ford Shale play

There are two figures that keep cropping up when folk write about the production of oil, one number is the daily flow rate for crude oil, and while the EIA report that the peak production year to date was in 2005, when the world produced 73.72 mbd, the IEA have reported that the peak occurred in 2006. Yet just last week the IEA raised their forecast for next year’s oil demand to 88.8 mbd and there is about 15 mbd difference between the two numbers. So you might ask what causes this, where do these additional liquids come from and what is their future, relative to that of crude alone.

Part of the answer comes from what are known as refinery gains, the fact that when you crack a high-carbon crude into lower carbon products in a refinery then there is a gain in volume. In Oil 101 Morgan gives this processing gain in volume to be around 2.2 mbd. In addition there is the rising level of bio-fuel production, about 900,000 bd of ethanol in the US alone, for example. But the largest volume comes from the liquids associated with the production of natural gas.

These are collectively described as Natural Gas Liquids (NGL) and condensate. Simplistically, when natural gas comes out of the reservoir it is not always what is referred to as a dry gas, but rather can often contain a number of other constituents in the fluid flow. The NGLs are normally a combination of ethane, butane, isobutene, propane and natural gasoline and are normally combined with other light hydrocarbons that condense out of the fluid flow at the surface, when pressures and temperatures fall from those in the reservoir. These additional fluids are the ones generally called condensates, as a result. (The NGL's need a little pressure to re-liquefy). NGL total volume is about 8 mbd. Now to make life somewhat more complicated both oil and gas can come out of the same well at the same time in a admix that can include all of the above. And that requires that they be separated, but that is a topic for another day or two. Today I want to give an example of the importance of those liquids that lie between crude and natural gas.

These mixtures can be more important, depending on the relative composition of the flows that are then obtained. Consider, for example, the Eagle Ford shale, the new field that is being developed in Texas, where wells that are to be drilled into the gas shale are now touted for their liquids content, rather than for the natural gas that they are more commonly anticipated to produce. When the field was first drilled, back in 2008, the initial well flowed with natural gas production of 7.6 million cf/d and there have been some 944 permits for wells as and of last week.

Wells in the Eagle Ford Shale Texas Railroad Commission

However it is not just the surface location of the wells that has to be considered. And if those of you with more knowledge will forgive the repetition, I need to just give a short paragraph of explanation about where oil and gas originally came from. Very simplistically they come from algae that flourished in the oceans of the time, somewhere between 65 and 500 million years ago. The algae contained some lipids (an oil precursor) as do those of today. As the algae died their bodies fell to the seabed where they accumulated in layers, along with the sediment that collected with them. Over time that nascent rock was buried deeper in the Earth’s crust and as it did the pressure and heat slowly changed the lipids, initially into oil. However if the rock was carried deeper, then the oil was further cooked and became natural gas. The process has been illustrated at the oil and gas geology website where I got this illustration:

Transition from lipids to oil and then gas over time and depth of burial ( Oil and Gas Geology )

As a rough rule of thumb down to 15,000 ft the hydrocarbon is more likely to be oil, (which is thus referred to as the Oil Window) and below that it is more likely to be gas. That is only a rough rule of thumb, and one must remember that over time there has been a lot of uplifting and eroding, so that 15,000 ft isn’t necessarily what it used to be.

And the Eagle Ford shale is a fairly good example of this. If we use the EIA map of the play you can see that in the North, where the reservoir is about 6,000 ft deep the hydrocarbon is oil, while further South, where the deposit is down at around 14,000 ft then the hydrocarbon is dry gas. And in between it is what is known as a wet gas.

Eagle Ford play showing the depths to the reservoir and the nature of the hydrocarbon (EIA )

You will also see that the majority of the wells are in the wet gas/condensate section of the field. As a result, when we look at the amount of the different fluids that have come from the field in the two years of major production to date, we get the following plot. And to make it, I have made the simple assumption that 6,000 cubic ft of natural gas is equivalent to a barrel of oil (which I call the Apache number )

Fluids produced from the Eagle Ford shale (Texas Railroad Commission )

You may note that the condensate from the wells in the wet gas zone have produced around 2.3 million barrels, while there has only been about 1.6 million barrels of crude produced. It is also worth noting that while the natural gas coming from the formation has been twice the equivalent volume of oil, the market for natural gas, at the moment is still down at around $4.6 per kcf, which using the Apache conversion, would give it a price of around $27.60 a barrel of oil equivalent. On the other hand the condensate is a light high quality product, and West Texas Intermediate crude is running at the moment at around $88.30 a barrel. (EIA last Natural Gas Weekly ) You should also remember that these are not the retail price for the products – natural gas in Florida, for example, was given as $10.56 per kcf, while it is around $9.81 in New York (ibid).

The current excess of natural gas over supply, which is likely to continue through at least next year (and which I will discuss in more detail in a number of future posts) will likely keep the price of natural gas down around the $4 figure through most of next year. On the other hand the increasing demand for oil when set against the limited ability of the industry to respond, will likely mean that oil may well move over $100 a barrel.

So now you know why they are drilling in the middle of the play known as the Eagle Ford Shale.
