Tech Talk - Here we go again, again

A couple of posts or so ago I mentioned that there are three major problems sitting relatively un-noticed as we head into the mess of Peak Oil. Of these, perhaps the one that gets the least attention is the steady decline in production from existing wells. We are just about at the point where the Alaskan Pipeline will tip over into feeding less than half-a-million barrels a day down from the North Slope. (It sent 501 kbd down the pipe in June with a 98.6% reliability factor). At the same time those in control of the oilfields in the Russia are reporting that Russian exports have fallen to the lowest level in 6 years. This brings back the relatively unrecognized reality of the Export Land Model which Jeffrey Brown first introduced on The Oil Drum back in 2007.

It is worth resurrecting that thinking (which time has proven to be only too true) as we look at the continued declines in production from the UK, as an example. It is not easily discernable from the official Department of Energy and Climate Change, which plots oil production on a monthly basis (with different months having a variety of days):

Figure 1. Monthly production of oil from the fields of the UK continental shelf (DECC ).

Euan Mearns has, however, done the necessary arithmetic and clearly shows the reality of the situation once one converts it back to barrels per day:

Figure 2. UK production of oil and natural gas over the past decade (Euan Mearns)

The steady decline has also been noted by the EIA who commented that UK production fell by 9% from 2012 to 2013. There was a time, back in the days of The Oil Drum, where we debated whether an estimate of 5% for field decline rates was or was not too high. Obviously those days are now behind us, and reality is starting to show numbers that far exceed the rates that, at the time, some thought rather pessimistic. To continue the UK numbers, as OPEC recently anticipated, the decline this year will take the total down to 800 kbd with an 8% decline expected for this year.

The Export Land Model, in its simplest form, can be illustrated with the following plot:

Figure 3. A simplified illustration of the changing production, internal use and exports for an oil producing country, once it reaches a peak in production (Sam Foucher )

The argument that produces the above plot goes along the lines that, as an oil producer (think for a moment of Russia for eg) produces larger volumes of oil, so the economy of that country starts to grow. As that growth continues it demands an increasing amount of energy to sustain the increased internal demand (the green line). However, once production stabilizes or starts to decline (the blue line above) so the amount available for export becomes reduced (the red line).

The three top producers of petroleum products in the world are the United States, Russia and the Kingdom of Saudi Arabia. The United States consumes far more than it produces, and thus is already a net importer of petroleum products, although in the short term, as I noted earlier production gains from the Bakken and Eagle Ford are hiding the problems of decline rate. It is increasingly unlikely that any significant volume of US oil will make it onto the world market.

Saudi Arabia has, for years, controlled the amount of oil that it puts on the market, based on the anticipated global demand, and the supply available from the rest of the world - so that the global price remains at a level to sustain OPEC economies. That has been illustrated over the past couple of years by the increase in production from the KSA to cover the decline from Libya as about a million barrels a day disappeared from the global market. The gains in production from the US helped in meeting global demand and the strain in supply was thus relatively easily hidden. But the KSA has an imminent problem that has largely disappeared from public view now that the eyes of The Oil Drum correspondents have lost that focus.

The major oilfields of the Kingdom are old, and to sustain production perimeter wells were located around the oilfields that injected millions of barrels of seawater a day, to drive the oil towards the center of the fields, where it could be relatively easily recovered from Maximum Reservoir Contact wells drilled along the very top of the reservoirs. But as folk such as JoulesBurn have noted, those wells slowly change in nature, over time, as the oil migration continues, and water injection must move inwards to ensure continued production.

Figure 4. Layout of initial wells at the Haradh III development in the Ghawar oilfield in Saudi Arabia (JoulesBurn at The Oil Drum)

He noted, in the original post, that Aramco had to drill some 52 wells, rather than the estimated 32, to get the production they needed, and that was back in 2010. Since then Ghawar has continued to produce for the Kingdom, but with daily levels of up around 10 mbd, the volumes in the crests of the anticlines along which the oil wells sit within the Ghawar field have been steadily contracting, and although they have carried out some of the most advanced oilwell engineering to sustain production from the attic oil in the older parts of the fields, there are only so many ways you can squeeze a rock before you get out all the oil that you will – and those days are approaching fast.

At the same time (relating back to the ELM) while Saudi production has remained at just under 10 mbd for the past few years, internal demand has been rising at a steadily more rapid rate.

Figure 5. Internal consumption of oil in Saudi Arabia (Index Mundi ).

Hoping to transition some of the current internal demands to natural gas, the KSA has been looking for internal resources to allow it to move away from oil. However the search has not been as successful as hoped, particularly with the search for natural gas, Shell having backed out of the program as a result of the poor results to date.

With internal consumption continuing to rise at more than twice the rate anticipated by the ELM shown in Figure 3, and, at best, stable production, global exports from the Kingdom are of increasing concern.

Which brings us back to Russia, where the new fields that must be exploited to sustain production are in remote parts of Eastern Siberia and the Yamal Peninsula – if not offshore in the Arctic.

Russian oil production has been peaking for some time (falling from 3.4% growth in 2012 to 1.3% in 2013) and is now reported to likely fall by 6.3% over the next two years. Since this implies that Russia is now at peak, the decline in overall production initially will fall below that of Figure 3, though likely only for a year or so, before the rate will be, at minimum, that shown. (The reason for this conclusion comes from the lack of enough investment in the fields where growth can be expected). At the same time internal demand is rising at around 100 kbd or 3% pa slightly above the value assumed for Figure 3.

If none of the three largest producers can even sustain exports, and the ELM explains why they can’t, and world demand continues to rise at the rates projected, then, in even the short-term, something is going to have to give. The logical weakest link is price, with the consequence, that invalidates a lot of the other arguments, of a significant impact on global economic health. As we have seen before, significant increases in price lowers the demand for oil, and thus demand from the various nations will become even more skewed.

The only problem, with this next iteration, is that there isn’t another Bakken or Eagle Ford conveniently sitting waiting to be tapped.

Tech Talk - Optimism is becoming harder to sustain

For some time the nations of OPEC have been suggesting that demand for their oil will remain relatively stable in the near future, as increased production from the non-OPEC nations is expected to more than meet demand increases. Thus, for example, in the May Monthly Oil Market Report OPEC anticipates that global oil demand will increase by 1.14 mbd this year, while non-OPEC production will increase by 1.38 mbd, allowing a slight reduction in the volumes OPEC market, which continues to fluctuate around 30 mbd. In the longer term, however, as previous annual oil company prognostications of future supply have emphasized, the MENA countries are going to be pulling an increased weight in supply. For example ExxonMobil has noted:

The Middle East is expected to have the largest absolute growth in liquids production over the Outlook period — an increase of more than 35 percent. This increase will be due to conventional oil developments in Iraq, as well as growth in NGLs and rising production of tight oil toward the latter half of the Outlook period.

At the same time BP pointed out that in just a couple of years demand for OPEC oil is likely to start to steadily increase.

Figure 1. BP view of the increased demands to be made on OPEC oil with time. (BP Energy Outlook 2035)

A large part of that increase has been expected to come from Iraq. With the end of the Iraq war, and the government encouraging development there were some claims that production might eventually rise to over 13 mbd (ahead of both Russia and Saudi Arabia). But those optimistic views had to be measured against the reality that the country has taken a long time to recover back to the 3 mbd levels of exports that it had achieved before conflict.

Figure 2. The fall and recovery of Iraq’s oil production. (EIA)

At present OPEC reports that Iraq was producing at 3.298 mbd in April, making it second only to Saudi Arabia (at 9.579 mbd) among the OPEC nations. There still seemed to be some chance that the country might be able to reach some lower target figures, such as those suggested in the OGJ.

Figure 3. Anticipated Iraqi exports and their market region (OGJ)

Regrettably violence is now significantly increasing in the country, with Mosul being over-run by Sunni militants. This puts them in charge of the main pipeline to Turkey, as well as giving them potential control of some of the adjacent oilfields.

Figure 3. Known Iraqi oilfields in 2010.

Euan Mearns has written of the potential for oil from the Kurdish regions and Turkey has just allowed a second tanker to sail from Ceyhan carrying oil from that region to the market, without Bagdad’s permission. The oil is being delivered through a new pipeline capable of carrying 100 kbd from Kurdistan into Turkey. The main pipeline (shown in Figure 3) can carry as much as 600 kbd and runs from Kirkuk and perilously close to Mosul. The new pipeline runs through Kurdish territory until it reaches Turkey.

The declining influence of the central government over the northern territories of Iraq does not bode well for future production gains. Conflicts are getting worse, and the country is approaching the point where it could well be partitioned, since the government forces seem unwilling to take on the insurgency. Violence has already spread to the Al-Bayji refinery some 130 miles north of the capital. This is the largest refinery in the country, and currently produces below its 300 kbd capacity, all of which is used for domestic consumption.

The problems that this reveals are unlikely to be resolved soon, it is much more likely that they will continue to escalate over the next months, if not years. The impact on Iraqi oil production should not be underestimated. While the oil in the Kurdish region can make its way through the smaller pipeline that is under Kurdish control, the greater flow rates needed to sustain future growth in supply cannot be met by that pipe.

In the South developments in the Mesopotamian region around Basra from the fields of Rumaila and Majnoon will likely continue, with production being shipped out from the new facility offshore, although this is already quite significantly behind schedule.

Figure 4. Oil fields of Southern Iraq (IEA )

One has only to look at the degrading situation in Libya, where production has fallen from 1.6 mbd to a current level of less than 200 kbd, with no path forward now evident for production levels to be restored. Those familiar with the region doubt that there will be much improvement in the situation this year, and if the country follows the Iraqi path (figure 1) then it is unlikely that the world will see significant Libyan production for this decade.

That loss of a million barrels a day is likely to become increasingly evident as world demand continues to grow at greater than that level each year. When this is combined with the increasingly inability of Iraq to increase production as it moves back into more vicious internal strife, then one has to ask from where can future gains in oil production be anticipated?

The major oil companies have urged complacency having bet on Iraq and OPEC coming through (and in the process assumed that Saudi Arabia would also increase production significantly above 10 mbd, something that they have consistently declined to commit to doing). As Libya and Iraq remove that surplus from the table then the question becomes where else can it come from?

It is increasingly unlikely that US increases in production can be sustained for long, given the very short high-level life of the new wells completed in shale, and as the sweet spots in the current fields are consumed. Thus within a couple of years we are now likely to see an increasingly desperate search for new reserves. But those reserves take years to find and develop (as well as large amounts of money), and if the crisis comes at a faster pace than most now expect, then $100 a barrel oil may seem an absurdly cheap price to have had to pay. It may even have an effect on the next Presidential election.

Tech Talk - A Dickensian Situation revisited

Back in March 2005 I posted my first offering to the new site that Kyle and I had agreed to call “The Oil Drum.” Now, some eight years later, this will be my final Tech Talk to appear on that site, and it is perhaps appropriate to go back to that first post, and make a couple of comments on how it panned out. It read as follows:

When I was young I was fascinated by a small china statuette that my Grandparents had of Mr Micawber. He is a character, and a sympathetic one, in Charles Dickens's book "David Copperfield", in the course of which he goes into debt, His explanation of his financial condition can be compared to the coming world experience as we now live through Hubbert's Peak. You might, in today's phraseology, call this the Money quote:

'My other piece of advice, Copperfield,' said Mr. Micawber, 'you know. Annual income twenty pounds, annual expenditure nineteen nineteen and six, result happiness. Annual income twenty pounds, annual expenditure twenty pounds ought and six, result misery. The blossom is blighted, the leaf is withered, the god of day goes down upon the dreary scene, and - and in short you are for ever floored. As I am!'.

In this case consider that our expenses, i.e. the world use of oil, went up last year to around 83 million barrels every day (mbd). (A barrel is 42 gallons). Now as long as our supplies (income) can match this outlay then we are in happiness. This was, in relative terms, where we ended last year.

However this year our expenses are going to go up. It is a little difficult to predict exactly how much but current predictions are for this to be around 2 mbd. Let us equate this to the old English sixpence (which was back then worth about a dime. Twenty pounds being worth about $100).

If we follow the Micawber example if our income, world oil supply is equal to or greater than our expenses then we can stay happy. But here is the rub.

When world oil production is just about as high as it can be (non-OPEC countries are now producing just about as fast as they can) and OPEC spare capacity is down to around an additional 1.3 mbd. then our income this year will likely not be much above 85 mbd, if it gets there. (In a later post I will explain why it probably won't).

So we are at the point where within the next few months income and expenditures will be in balance (Micawber's twenty pounds). Except that the industry being a big one there are always things going wrong. In the latter part of last year for example we had:
• the hurricanes in the Gulf that closed down about 0.5 mbd of production for several months,
• oil production in Iraq, which should be around 3 mbd, but because of pipeline bombings etc dropped below 2 mbd,
• there were frequent threatened strikes on the oil platforms in Nigeria,
• and Russian production declined more drastically than had been anticipated.

Some of these are still with us, some have been resolved. And other problems, such as the complete employment of the world tanker fleet, have yet to make an impact. But any one can drop supply.

Yet while our supply (income) is about at a peak (twenty pounds), our expenses (demand) are still going up by this sixpence a year. So that some time this year expenses will have gone from twenty pounds to twenty pounds and sixpence. A number of economists had been predicting that there would be a reduction in the rise in demand to keep us below that figure, but it is already clear that they do not adequately recognize the considerable needs in China and India that drive this increase (and they only have to read the papers to see it).

The big question is when will we reach the point that we cross over the balance point. Right now with the Saudi Arabian government saying that they can increase production by up to 1.5 mbd one might think we could get through to just about the end of this year. Unfortunately some of us are a little cynical about that number, and I'll explain why in another post.

One final gloomy thought - production in other countries (such as the UK) is falling, and the countries that used that supply must find another source. And if we are now at the peak of production, then our income cannot increase above twenty pounds and and may indeed fall back below twenty pounds, while our expenses will continue to increase to twenty pounds and sixpence. It is not the absolute size of the market that will now drive, but the relatively small fluctuations that take us out of balance.

The result is misery, and we are for ever floored.

Looking around it is reasonable to note that we don’t see the level of misery that, from reading that post, one might have expected to happen. We have gone through a major recession, yet demand has, overall, increased and production has risen to meet that demand. Yet looking at how this has been met is instructive.

Figure 1. Changes in liquid supply sources from 2000 to 2040 as anticipated by Exxon Mobil, with lines added to show 2005 and 2013. (The Outlook for Energy: A view to 2040)

I have added lines to show the situation in 2005, when the piece was written, and for this year. It is worth noting that, using the definitions that Exxon Mobil give, conventional crude and condensate production has, indeed, declined since I wrote those words. And if one includes Oil Sand and Deepwater then production has remained fairly stable at the levels back in 2005, and will (according to EM) likely stay so into the projected future.

The three sources that I had underestimated, in terms of production growth were in Biofuels (which is now at around 2 mbd), the growth in Natural Gas Liquids (which for OPEC alone is now projected to reach 6 mbd by next year up from around 3 mbd in 2005, and the growth in tight oil. This latter development, particularly with the use of long horizontal wells that are artificially fractured and injected with a slick-water suspension of a proppant, has been very successful in developing resources which were otherwise at best marginally economic. However the relative contribution that this is expected to make in overall supply is not that great, and I expect that, because of the high decline rates in individual wells, that this will only contribute on the margin of the problem.

When I began writing at The Oil Drum I was concerned that there was a lack of understanding of the impact that reservoir decline rates would have on long-term supply. As larger fields are depleted, so the world turns to smaller fields and these drain more rapidly, so that more and more are needed. (The Red Queen situation that Rune Likvern and others have so aptly described.

Deepwater resources have proven to be more difficult to bring on line than originally estimated and thus, for example, in the case of Brazil OPEC now anticipates that the production from the Lula field (originally Tupi) will only offset declines from wells in the rest of the country, with perhaps only a gain of 10 kbd overall from the addition of the 100 kbd expected from wells now coming on line. And thus, while this is a resource getting more attention (there are expected to be 60 Deepwater rigs in the Gulf of Mexico by 2015) the slow pace of development may not fill the increasing gap left as conventional oil production continues to fall, as Exxon Mobil suggest.

In retrospect, therefore, I was wrong in anticipating a relatively immediate impact from an anticipated imbalance between oil supply and demand. But, within the time frame the price of oil has risen, and the future looks no happier than it did back in 2005. The threats have changed – we seem to be in a quiescent period for major Gulf Hurricanes, for e.g. – but the threat of growing and spreading turmoil in MENA makes it less certain that we can count on much increase in production from Iraq, among others. Russian production rebounded more than I expected, but whether that can be sustained is still in doubt. The hope, at the beginning, was that the threat would spur increased looks into alternate sources of liquid fuel. But while there was a flurry of activity into biofuels (and I myself saw algal work that held a great potential, - though funding has now disappeared for that effort) there is less of a feeling of urgency in the air. Wind and solar sources have reached a point where they are no longer novel, and there is not much else in the near term that holds much potential.

Oil production takes money and resources, but most critically it takes time. Without that investment, particularly in viable alternatives, the oil “income” (supply) will likely soon start to fall short of the oil “expenses” (demand) and as Mr. Micawber so aptly said “we are forever floored.”

When these posts began, technical blogs, such as TOD, posed the potential for mass education in a way that had not been seen before. Readers have been kind in regard to the quality of the posts themselves. But the contributions from those interested, and those in industry who took the time to comment and debate ended up making this much stronger than the initial words in any post. Expertise came in many forms and informed me as well as the rest of the readers in what turned into a wonderful opportunity for many people to understand some of the complexities of supplying the world with hydrocarbon energy. I was thus able to help bring a little understanding of the energy business to vastly more folk than I had in the entirety of my academic career.

I will always be grateful to Kyle for giving me the opportunity to make this contribution, and to his efforts which led to its great success. I can illustrate that with some numbers – as an academic I took persuasion to allow my class size to rise much above 20, and at Bit Tooth Energy I see about 300 readers on a typical good day – Kyle had us above that number in a very few months, and at its peak TOD was handling 200 times that number. The site would not have continued too long as it grew in size without the indefatigable SuperG, who kept the site up under wide ranging pressures, and took care of the technical side of the house. Leanan brought and kept us readers, and provided many of the topics that we needed to create the posts on site, and Gail kept me going with encouragement and support in more difficult times. Nate orchestrated the closing posts and that was not easy.

The folks Kyle brought in to build an international forum were formidable and highly productive, and so to them, and to all of the gentle readership I say again a heartfelt “Thank You!”

(Heading Out – Dave Summers in the mundane world – will continue to write Tech Talks at Bit Tooth Energy, though he writes on a wider range of topics at that site).

P54. Pick Points

So here it is the weekend, and I would usually be putting up Saturday Pick Points, and the Saturday post, with Sunday’s Tech Talk in the wings. However, since I am still wandering around Europe (tonight I am in London, but leave early in the morning for Dumfries and Burns Country) I am, instead going to take a quick peak around and do sort of an abbreviated Pick Points, looking at some half-a-dozen or so stories that are worth a quick look.

Getting around as I do involves a fair bit of travel by plane, and I’ve noticed that the planes seem to be getting smaller, and thus fuller, as the economy spins away. Of course the increased traffic might be because some travelers, can’t have a new jet of their own, though I doubt it. China is now providing its suppliers with increasing quantities of jet fuel, perhaps suggesting that while the rest of the world is cutting back , they continue to grow. Cutting back is almost the universal cry, and certainly the restaurant business has to be hurting. And I have eaten in a number of places recently where I was one of only few customers. Of course sometimes it is because, when I go to places like the Fem Sma Hus in Stockholm I show up at American dinner times not European (most of my meal I was alone in the cellar, but just before I left it became crowded). This lack of demand hurts chef employment, in NYC the restaurant trade lost more than 10,000 employees in the three months over the end of the year, nationally the drop has been more than 100,000. And with reduced waitstaff, in more popular places this can catch management out when there is an evening surge in demand. Which may “earn” you a free glass of wine as it did for me tonight in London. Sadly, however, sales of alcohol often pick up in troubled times, as they are now in Russia, while the harsher economic environment means that the smaller firms are pushed out of the trade.

Robert Rapier has noted that this is a good time to pick up alcohol – though he is talking of the ethanol variety in his most recent column at R-Squared Energy Blog: Valero Now in the Ethanol Business. As he notes VeraSun, the nations second largest ethanol manufacturer, filed for Chapter 11 at the end of October. The corporate assets are now on the block, and Valero Energy stand to pick up the seven ethanol refineries, at a quarter of the construction costs. Other ethanol companies have already filed for bankruptcy protection, and it appears Aventine may soon be in similar straits. Yet even as these sales start, the scale of the volume that ethanol will contribute, relative to the coming need is small, and while it provides, as Robert notes, an easy way to pick up a fuel that is being mandated as part of future supply, for small change to the oil companies, it is not going to be more than a contributory part to the answer. Yet, at the moment, despite that mandate, farmers are planting a greater fraction of the crop in soy beans this year, anticipating a bust in corn prices (which prophecy might be self-defeating). On the other hand if the import tariffs are reduced, as some in the Senate suggest, we may be able to import all we need. (But wasn’t there this slogan about freeing ourselves from imported fuel dependency?) Even the Wall Street Journal has weighed in against ethanol, though that also gives me the chance to make a small technical note. Unless I am doing something stupidly wrong (not unlikely) American Kindles can’t yet pick up magazines and papers in Europe (neither Sweden nor the UK). So much for my plan to save weight in my carry-on baggage by just loading the papers to it – Rabbits! Though I guess they may have other bigger troubles.

Solar panel advocates can no doubt breathe a sigh (though they said it was rather a shout) as the final Space Station panels were successfully installed. The station now has enough power to allow double the crew. Down on Earth the Administration is making its first Federal loan guarantee for alternative energy. The guarantee is for $535 million and will help construct a PV facility that can generate panels to produce up to 500 MW per year. The panels are designed for use on rooftops. The world’s solar PV installations are stated to have reached a combined total of almost 6 GW by the end of last year with Europe getting 82% of the business to date. (The ranking by country is Spain, Germany, USA, Korea, Italy and Japan). Sales are thus on a positive upward trend, with DuPont estimating a trebling of sales by 2012. First Solar have also just announced that they have now produced 1 GW of their solar modules, so with manufacture gearing up, all we need now is the market growth.

The other major renewable, wind power, is also gaining market, with a new effort to put turbines into South Africa. The country, as you may remember, has had problems with suppling power, not only for its own needs, but that of its neighbors. The first 30 MW farm is not scheduled until 2011, which won’t help the intervening shortages. It will, however, quadruple capacity. Eskom – the main SA power provider needs a rate increase, but is having trouble getting its act together, and having a power failure at a rally to improve their public posture sure doesn’t help. It is frustrating enough to Botswana, who got most of their power from SA, that they have started seeing pink elephants. (Would I lie to you ?). Of course it’s not just the South Africans that can run into infighting over turf relative to wind power, though the new Interior Secretary promises to get it stopped.

And finally (as the clock kicks over here in London) it is 4 years ago that Kyle Saunders and I first posted our collaborative effort that was, and is, The Oil Drum. I have posted a short history of the site, over there, and repeat the very best wishes that I have for the site. It has filled a valuable need, and that will not diminish in the months and years ahead, and so my wish that the site “Live long, and Prosper.”
