Tech Talk - of Alaska, Libya and the belated bleat of awareness of a problem

I have written in earlier posts about the problems that the Trans-Alaskan Pipeline System (TAPS) will face, as production declines below 500,000 bd. The conclusions from that post are pictorially summarized in a graph in the recent edition of the Oil and Gas Journal.

Figure 1. Declining throughput through TAPS showing the points of concern (OGJ)

Looking at current figures, in September the pipeline had an average throughput of 524,181 bpd against the year-to-date average of 528,092 bpd. It has just passed below the upper limit at which operational difficulties can be anticipated, due in part to the flow being too slow to keep the temperature high enough to prevent wax from separating from the fluid, and starting to block valves and critical infrastructure. Because of the long lead times, and high capital requirements for the development of new fields in the Arctic, and the likely probability that these will not yield significant production until at least 2025, the article is pessimistic about both the fate of the pipeline, and future Alaskan production.

Despite those declines OPEC remains optimistic, in their October Monthly Oil Market Report that the world producers can continue to meet global demand as they foresee it rising to an average of 89.7 mbd this year, and then going up to 90.8 mbd on average next year. They foresee, for example, that non-OPEC supply will increase this year by 1.1 mbd (to 54.1 mbd) led by production gains from the USA, Brazil, Kazakhstan, South Sudan and Sudan. Next year they see an additional non-OPEC growth of 1.2 mbd with Canada replacing Kazakhstan among the five countries that will make up this additional production. In contrast OPEC itself is reducing production, with overall production reported to be down 390 kbd in September.

The gain in crude oil production seen in the US, which has risen from 5 mbd to an average of 7.3 mbd in the first seven months of this year has had a significant impact on these projections, though the change in the mix of product now available to the Gulf refineries will continue to have some impact on the overall import picture. This is because, as the EIA note, some of the heavier crude refineries along the Gulf are tied to foreign producers including Pemex of Mexico, PDVSA of Venezuela, and Saudi Refining (for a combined total of just under 2 mbd).

Yet it remains difficult to sustain the optimism that OPEC project. Libyan exports, at one time running up around 1.25 mbd remain down at some 90 kbd, due to tribal disruptions and internal political disputes that show little sign of resolution.

Figure 2. Recent Libyan oil production (Energy Policy Info)

Certainly the physical ability to return to around pre-disruption levels has been demonstrated, but the weakness of the central government does not indicate that the political problems will be resolved in the near future. And until they are there is the best part of 1 mbd being with-held from the market. This drain from global supply is not yet disruptive since it has, to date, been largely picked up by the Kingdom of Saudi Arabia (KSA).

The picture from the combination of Sudan and South Sudan following the division of the one country into two has not been promising, however it appears that the overall total decline has now been halted, and recent reports have raised production to somewhere between 190 kbd and 240 kbd.

Figure 3. Change in oil production from Sudan and South Sudan following the division of one country into two. (Council on Foreign Relations )

The IEA is not optimistic that the return to production will be as smooth as others think:

“Industry sources have been quoted as saying that restarting oil production could take six months or even longer, since the lines have been filled with water and because some wells were not closed properly.”

The OPEC projection that overall Sudanese production has returned to the 240 kbd level may, therefore, be still an optimistic estimate. The increase to 175 kbd following the repair to the pipelines from the Majnoon field in Iraq is encouraging (although the high level of violence that continues in that country does not give high confidence that the pipeline might not be struck again.)

The increased production from the Kashagan field in Kazakhstan – anticipated to rise to 75 kbd - has again been hit following system leaks so that this increased production that OPEC had anticipated has, again, been postponed.

And while production has now started from the Espirito Santo in the pre-salt fields off Brazil, it is not clear whether the production gains will offset the declines that have occurred in Brazilian production in recent months.

Figure 4. The Espirito Santo floating production storage and offloading (FPSO) vessel (Shell )

Just as there is a perception that the United States is heading toward independence in energy needs (a fallacy I have written about several times in the past), so there is a perception that OPEC is becoming a less critical supplier. This is far from the case. KSA has been producing over 10 mbd for the last months, in order to offset the loss in Libyan oil to the market, and the combined production of KSA, UAE, Kuwait and Qatar now supplies 18% of global demand. This is only the second time that this number has been that high in the past 30 years. It comes at a time when the Middle East is supplying 25% of Chinese oil demand, as that country passes the United States to become the largest importer of oil.

Figure 5. OPEC oil production (numbers compiled from secondary sources (OPEC MOMR October )

This comes at a time when the world still wonders about the actual oil balance as it flows in and out of China.

Unfortunately the picture that is emerging continues to show that OPEC is tending to be overly optimistic in its forecasts for production, which does not bode well for future supplies of fossil fuel.

Given that a group of environmental scientists have just released a letter calling for increased investment in nuclear power since, to quote James Hansen:

Hansen, who’s now at Columbia University, said it’s not enough for environmentalists to simply oppose fossil fuels and promote renewable energy.

“They’re cheating themselves if they keep believing this fiction that all we need” is renewable energy such as wind and solar, Hansen told the AP.

This comes a bit late, since as I noted recently, it takes over a decade to build a new nuclear power plant, and with the current schedule for existing plant closures moving inexorably along their timetable, this may presage a decade of power shortages. We shall see!! But in the meanwhile we had better hope that those folk concerned over the possible shut down of the Trans Alaskan Pipeline because of inadequate flow are being just a tad pessimistic.

Tech Talk - Where to look for more oil this year.

The news that Saudi Arabia is planning to employ 200 drilling rigs next year (up from 20 back in 2005) suggests that there is a recognition that future reserves may not measure up to the planned volumes needed. Plans now include exploration of the shale deposits in the country, looking primarily for natural gas. There are estimates that this resource could run as high as 600 trillion cubic ft. Current plans are to drill seven exploratory wells in the Red Sea, off Tabuk.

Figure 1. Location of Tabuk in the Kingdom of Saudi Arabia (WikiMedia )

This is across the country from the major oil fields currently in use, which lie more along the Persian Gulf coast, centered perhaps around Damman. It therefore suggests that they are looking for extensions of the Israeli and Egyptian fields into northern KSA. (Minister Al-Naimi said that they still “had to find them.”)

In discussing the venture Saudi Minister of Petroleum and Mineral Resources Ali Al-Naimi also noted that, choosing to look for – and presumably finding - natural gas, would take the pressure off the country to maintain its oil reserve.

Al-Naimi said that prospects for global production of shale gas and oil – including in China, Ukraine, Poland and Saudi Arabia – were so promising that the Kingdom might not need to continue with its decades-long policy of maintaining an oil-output cushion for use in global supply disruptions.
“It is not a question whether Saudi Arabia has spare (oil) capacity. It is a question of whether we need to spend billions maintaining it at all,” Al-Naimi said.

Now over the years KSA has lowered the volume it has projected that it can produce from 12.5 mbd to 12 mbd, and this is, perhaps, an early indication that they intend (whether by policy or natural reserve availability) to lower that maximum further.

This has to be of at least a little concern, since the number of places with significant flexibility to increase production are getting closer to zero every year. The gains in global production that are foreseen by OPEC in the next year, for example come in dribs and drabs.

OPEC notes that in May the 8,915 producing wells in North Dakota collectively produced over 800 kbd. (The Department of Mineral Resources reports 821 kbd in June, over the 811 kbd in May with well numbers of 8,932 in May and 9,071 in June. Production per well is thus running an average of 90 barrels a day, with a well cost of $9 million.) There are 187 rigs plus/minus working and this is still enough to keep production rising at a rate of 1.3% per month. One of the maps I find interesting is this, from the Department.

Figure 3. Location and production values for wells in North Dakota (Department of Mineral Resources )

It is this illustration of the relatively heavy drilling already in the “sweet spots” and the poorer performance in the less well drilled regions that gives me concern for the longer term prospects for the formations. And as an aside note that crude from Alaska is declining, July output was 498 kbd against the year-to-date average of 542 kbd. The EIA is noting that, since there aren’t any major oil pipelines running into California from the East, that there is an increase in rail traffic to make up the difference. The EIA is suggesting that the traffic is already at a level of around 100 kbd.

And this in happening in the most promising region to increase production (though it includes Canada, for which OPEC projects a growth over the year of around 40 kbd, which is set against Mexican production, for which OPEC sees a decline of around 60 kbd).

Malaysia is projected to increase production by 50 kbd, from the Gumusut field. This is a Deepwater project, and one can get some estimate of the shape of the field from the well pattern. The production gain is viewed by OPEC as likely being the highest in the region.

Figure 4. Planned Well pattern for the GUMUSUT KAKAP project in Malaysia (Rawingbadi)

In Latin America Colombia is expected to increase production by 80 kbd, though the country is having some issues with pipe damage from terrorism. There have been more than 30 attacks this year. OPEC also looks for an increase in Brazilian production of 10 kbd over the year, this gain coming after some 14 months of decline, which drop hopefully will be recovered before the end of the year.

Oman will grow production by 20 kbd, but it is in Sudan and Southern Sudan that OPEC anticipates the greatest growth, of 90 kbd. However the two countries are not the best of friends, with oil from Southern Sudan having to ship by pipeline to Sudan, for shipment onwards. At present oil, at an average rate of 75 kbd is continuing to flow up the pipe, but Sudan continues to threaten to halt shipments, leading Southern Sudan, in turn, to plan to shut-in the wells. The OPEC projection seems to be best defined therefore as “iffy.”

OPEC expect Russia to increase production by 80 kbd in 2013, yet there is some caution in that estimate, with other numbers suggesting that Russia is reaching a modern peak in production. Kazakhstan is projected to increase production by 50 kbd (coming from the startup of Kashagan, now expected at the end of September). The 100 kbd production will more than offset declines in the rest of the country. And China may increase production over the year by 60 kbd.

I have listed the countries that OPEC anticipates will grow production by more than 10 kbd, and have not listed the many countries that will see production decline by more than that amount. It is remarkable that listing the increases in production outside of OPEC can be done with just a few paragraphs. And it is a little disturbing that the threats to pipeline security throw questions over the reliability of some of the numbers. And yet this only addresses the possible growth in production, declining producers would require a much longer list. Combined it becomes a little more difficult, as turmoil in MENA continues to grow, to remain optimistic over the OPEC projections.

The Sundering of Sudan - it may increase oil production

The disruption that began in Tunisia is continuing in Egypt, with changes also starting in countries such as Jordan and Yemen. And in the midst of this turmoil, the (finally) democratically dictated separation of Sudan into two separate countries is moving towards the July 9th separation date. At that time Southern Sudan will divide from the North. Sudan has only been selling its oil on the world market since 1999 and the transition will impact those exports.

With the hopeful end to the conflicts in the country, there is also now an increasing possibility that the oil and natural gas resources of the two new nations will be developed. Until recently China has been the most active player in the region, but as the results of the vote have become apparent, Russia too is indicating an interest.

Like other players in the world oil market, Russia would like to promote its energy interests in that region. Moreover, it is capable of becoming a serious competitor for both Western and Chinese companies in oil production and power supply. Russia’s clear competitive advantages are its technological experience in developing oil fields in many regions of the world, its investment potential and the absence of any political conditions for energy cooperation. The latter is important both for Khartoum and Juba, the current administrative centre of South Sudan, because after the referendum both sides will have to reconsider the criteria of their independence.

The EIA notes that in 2009 oil was the major revenue generator for the country, bringing in more than 90% of foreign earnings. Within the country the primary energy source is that of combustible renewables and waste, reflecting the rural, non-electrified population of much of the country. And although BP (as reported by Energy Export Databrowser) suggests that virtually all the oil it produces is exported:

Oil statistics from Export Data Browser, based on the BP review.

The EIA find that there is a significant, and growing, domestic market, that uses a significant percentage of production. Various estimates of the size of the export market (for reasons given below) hover around the FT estimate of around 500,000 bd.

EIA statistics on Sudanese oil production.

The EIA note, as is shown on the graph above, that production and exports developed after a pipeline was run 1,000 miles from the oil fields up to Port Sudan. And it should be noted that while about 75% of the oil reserve (perhaps 6.5 billion barrels) is mainly in the South, that port (map above) is in the North. And as European nations in particular, but also those of the FSU, know from the past, those who control the pipeline can often remain in a position of power. The previous arrangements and actual distribution of funds have been viewed with some suspicion.

Much of this is due to the opacity with which Khartoum's captured state machinery operates, siphoning as much as 40% of total oil revenue through various forms of mispricing. Meanwhile, though the Comprehensive Peace Agreement (CPA) of 2005 established that 50% of revenues must be remitted to the Government of South Sudan (GOSS), this share is determined not by volume but sales. Khartoum markets the oil nearly exclusively and determines price as well as volumes exported, with little or no independent monitoring. According to U.K. watchdog Global Witness, major discrepancies of between 9% and 26% have been documented, underpaying the GOSS by as much as $700 million. Little is known of the $7 billion in oil revenues remitted to the South as accountability mechanisms were never factored into the CPA.

That initial agreement is set to expire this July. The pipeline supplies oil to two refineries (at El Obied and Khartoum) that supply the domestic market.

Current pipeline and bid blocks in Sudan (USAID )

One thing that may change this is the construction of s second pipeline, running from the South to Mombasa in Kenya. This would also feed a new refinery proposed for Lamu, which is near Mombasa. However the pipeline would be 870 miles long and have to go uphill to get into the Kenyan highlands, making it quite expensive. An extension of a railway line has been suggested as an alternative. But it now appears that the rail link will go through Uganda, rather than directly to Lamu.

Possible oil routes South from the new capital at Juba.

North Sudan is currently producing about 100 – 110,000 bd of Sudanese total production, but it hopes, by increasing production from the Balila oilfield in South Kordofan from 60 kbd to over 100 kbd, among other gains, to raise this level to 195 kbd by 2012. It has also been exploring for oil offshore in the Red Sea.

Meanwhile exploration in the South is expected to increase, and there are hopes that production might increase to 2 mbd by 2015, from their current estimated production of 450 kbd.

Conditions in the South however are not currently ideal for oil production, even for the Chinese

He said trucks bringing in fuel vital to operations were stopped at 12 illegal checkpoints on one 200km stretch of road alone, each time being charged $300. Waste oil has been set ablaze and workers kidnapped, he added.

These conditions may make China less likely to invest at the scale required for the new transport network. On the other hand China is but one of several partners in production.

For while China has a 40% interest, Malaysia has a 30% interest, and India in 3rd place with 25% in the current production company. And with the Russians expressing interest, who knows what may transpire.
