US gasoline squeezed by rising demand and changing specifications


Gasoline prices in the USA have been setting new records despite the fact that the driving season is still several weeks away.  Part of the explanation for this year’s high prices is the general growth in demand, added to which is the fact that domestic refinery capacity is hardly growing at all, while gasoline inventories are also low.  A further factor, however, is the change in gasoline specifications introduced at the start of the year.  New limits were imposed on the sulphur level in gasoline and three states banned the use of an important additive, methyl tertiary butyl ether (MTBE).  Since the USA is the world’s largest gasoline market and an importer of gasoline, these changes are having an impact well beyond the borders  of the USA, as far afield as Europe and even Asia.

Growing demand

The US Department of Energy expects domestic gasoline demand to average 9.3 mn bpd in 2004.  This represents a 4% increase over 2003 and is taking place despite this year’s record price levels.  Gasoline accounts for the largest proportion of the USA’s demand barrel (see Table A) and the US gasoline market is by far the world’s largest, accounting for nearly 40% of world gasoline demand.

       The growth in demand, combined with the low level of inventories, has propelled US gasoline prices to record highs this spring.  Gasoline futures exceeded $1.24 a gallon in April, setting new records for the New York Mercantile Exchange (Nymex).  High gasoline prices have also played a role in pushing US crude prices over $40 a barrel.

Strong US gasoline demand has driven up prices elsewhere, particularly in Europe, which is an important supplier of gasoline and gasoline components to the USA (see ‘Focus’, March 2004).  The US market has even helped to support gasoline prices in East Asia, which supplies product to the US West Coast and Gulf Coast.

       The situation in the USA has been made worse by this year’s cold winter, which delayed the switch by refiners from making heating oil to raising their output of gasoline in order to build up inventories in advance of the summer driving season.  As a result, oil industry stocks of gasoline are lower than expected.  At the end of April, stocks amounted to 200 mn bbl: 3% below year-earlier levels and 4% below the five-year average.

       Another factor in creating shortages is the slow rate at which refining capacity is increasing.  Environmental controls make it almost impossible to build refineries on greenfield sites; so all the expansion is coming from the modernization, extension and debottlenecking of existing refineries.  Such capacity increases, however, have slowed down markedly in the past two years.  There are even plans to close some refineries.

       In September this year, Shell will close its 70-year-old, 66,000 bpd refinery at Bakersfield, California.  As well as being the largest gasoline market in the USA, California is also a net importer of motor spirit.  Refiners in the state of Washington say they will increase exports to California, but there is considerable doubt over the ability of marine terminals in the Seattle-Puget Sound area to handle the extra volume.

       Elsewhere in the USA, small refineries are being marked down for closure, either because of their size or their inability to afford the investment needed to produce the new fuel specifications demanded by federal and state legislators (see below).  A survey by the Oil & Gas Journal reported the closure of two US refineries in 2003: the 30,000 bpd American International Refining plant at Lake Charles, Louisiana, and another 30,000 bpd unit in the same state, the Church Point refinery, owned by the Canal Refining Company.

Changing specs

US gasoline’s problems are as much political as they are to do with demand and supply.  Indeed, gasoline is the most political product in what is more generally a highly politicized industry: and nowhere is this more so than in California.

       The politics of gasoline are closely bound up with issues of air quality.  In the 1980s, California’s legislators began to address seriously the problem of photo-chemical smogs in the Los Angeles Basin.  Here, temperature inversions frequently trapped tailpipe emissions from motor vehicles, causing dense and often choking smogs.  A number of bodies at both the local and state level began to press for changes in the specification of motor gasoline in order to alleviate the problem, among which was the highly influential California Air Resources Board (CARB).

       The upshot of these events was a series of proposals aimed at improving the combustion properties of gasoline in order to reduce the concentration of pollutants in the atmosphere.  Similar issues were taken up by other US states until, in 1990, a comprehensive clean air act was signed into law covering the entire USA.  Among the requirements of the act were minimum levels for the oxygen content of gasoline that were designed to make combustion more efficient.  These specified a 2.0% minimum content by weight, with a higher limit of 2.7% in winter for the most polluted areas of the USA.  Such gasoline became known as ‘reformulated gasoline’ and it accounted for round about one third of the entire US gasoline market.

       The oxygen was added to the fuel in the form of compounds containing oxygen known as oxygenates.  These included methyl tertiary butyl ether (MTBE), which could be made from natural gas, and ethanol, made from corn.  Such compounds constituted about 10% of the reformulated gasoline by volume.  They were thus seen by many politicians as not only improving the air quality of many US cities, but also as reducing the volume of crude oil required to manufacture gasoline, and thereby helping to keep down US imports of crude.

The rise and fall of MTBE

MTBE proved the most popular of the various oxygenates, especially in California.  Not only did it provide the necessary oxygen content for gasoline, it also improved octane levels.  It also provided a market for methanol, a gas-based product then in oversupply, and isobutylene, a by-product from refinery and petrochemical cracking units.

       Its use spread to other parts of the world, including parts of Latin America, the Middle East and the Asia/Pacific region, becoming the fastest-growing chemical of the early 1990s.  In some European markets, MTBE was added to petrol to replace the octane lost when lead was eliminated from motor spirit.  Production capacity grew in the USA to meet both domestic demand and a growing trade with Latin America.  Capacity grew even faster outside the USA, however, as countries such as Saudi Arabia and Malaysia set themselves up as suppliers to the burgeoning US market.  By 2000, production capacity worldwide had reached 0.6 mn bpd.  Consumption by then was only 0.5 mn bpd, though many expected it to rise as other countries opted for the oxygenate.

       About this time, however, serious doubts were beginning to emerge in the USA about the role of MTBE.  California, in particular, was beginning to have second thoughts.  In some areas, such as Alaska, it was claimed that the use of MTBE actually increased levels of air pollution.  The main issue in California, however, was the contamination of some of the state’s water supplies by MTBE.

       By this time, California accounted for more than a third of US consumption of MTBE, then around 0.3 mn bpd.  Studies by the California Energy Commission and others found traces of the oxygenate in lakes and groundwater.  In the first place, the origin appeared to be power-boats and jet skis with inefficient two-stroke engines, which emitted MTBE and unburned hydrocarbons into the lake waters.  Rather than seeking to ban the water craft, however, the state’s politicians singled out MTBE as the villain of the piece.

       Other studies about the same time showed leaks from oil industry installations such as gasoline stations into aquifers that were used for the abstraction of drinking water.  California relies heavily on shallow boreholes for its water, which are often sunk into permeable alluvial deposits that are easily contaminated by leaks from installations at ground level.  Fears about MTBE contamination were hardly allayed by reports purporting to demonstrate that the oxygenate was carcinogenic. 

       Pressures for a state-wide ban on MTBE mounted and a law was passed by the state’s legislature to implement this.  One of California’s senators began to press the US Congress for federal legislation on MTBE. 

       As has happened more than a decade earlier, where California led, other states followed: New York and Connecticut opted to ban MTBE from the beginning of 2004, the same date chosen by California (see ‘The Month in Brief’, January 2004).  Another 14 announced bans of their own covering the period up to 2006.  Some states began to file law suits against manufacturers of MTBE for contamination allegedly caused by MTBE.

       As a result of the controversy surrounding MTBE over the last few years and the growing number of prohibitions on its use, US consumption has fallen sharply.  Between 1999 and 2003, demand in the whole of the USA declined by 31%, while that in California fell by more then two-thirds (see Table B).  The ban in California, New York and Connecticut will reduce the consumption of MTBE by a further 65,000 bpd in 2004.

       The fall in MTBE use has been accompanied by the announcement of MTBE plant closures, including two in Texas and a third in Wyoming, which will remove some 32,000 bpd from the USA’s total capacity of nearly 260,000 bpd.  Other plant closures are inevitable, not only in the USA but in exporting countries across the world.

Replacing MTBE

In most instances, MTBE is being replaced in gasoline by ethanol made from biomass.  The use of ethanol has been heavily promoted by political and industrial interests from the US Corn Belt states and is also supported by those wanting to increase the role of renewable energy in US consumption.  An extensive programme of ethanol plant construction is under way, principally in the corn-growing states of Iowa, Kansas, Nebraska and South Dakota.  US consumption in 2003 amounted to about 175,000 bpd, compared with a domestic production capacity of around 200,000 bpd.  A further 35,000 bpd of ethanol capacity is planned for 2004.

       Not everyone, however, agrees that ethanol is the answer to the removal of MTBE.  Ethanol’s critics charge that its manufacturing process is energy intensive, involving as it does, evaporation and drying of wet grains.  Some opponents go further and claim that the use of ethanol in gasoline leads to increased emissions of oxides of nitrogen and volatile organic compounds, compared with MTBE, citing evidence from southern California where ethanol is already in use.  Ethanol is not as easy to handle as MTBE, either.  It requires dedicated transport and storage to prevent it from coming into contact with water, since even very small amounts of water contaminate ethanol.  Others oppose the increased use of ethanol on the grounds that it requires a government subsidy.

       Some oil industry groups say the problem is not one of replacing MTBE with another oxygenate but with the whole idea of adding oxygen to gasoline in the first place.  Studies quoted by CARB show that some gasolines burn more efficiently without the addition of oxygen.  There is a growing view in some quarters that the government should set the emission standards to be met by gasoline and then leave the refinery industry to decide for itself how to meet them.

       One problem that the removal of MTBE does cause, however, is a lowering of the octane rating of the resulting gasoline blend.  One way to boost octane levels if ethanol is not to be used would be to add more aromatics, which are a common by-product of refining and petrochemical operations.  Aromatics, though, produce more pollutants in vehicle exhausts and have been identified as carcinogenic in certain concentrations.

       The other main non-oxygenate option is to use more alkylate in the manufacture of gasoline.  Alkylate is already an important component in US gasoline.  US refiners have some 1.1 mn bpd of alkylation capacity out of a world total of 1.9 mn bpd.  Apart from improving octane levels, alkylate has the further advantage of being less volatile than many gasoline components, thus keeping alkylated gasoline within federal limits for vapour pressure.  Most US alkylate is produced in the Gulf Coast region.  It is doubtful whether there is sufficient spare capacity there to replace MTBE in both California and in New York and Connecticut.  Given the logistics of supply, most of the Gulf’s spare production is likely to head north-eastwards.

Reducing sulphur

The removal and replacement of MTBE is not the only challenge facing US refiners in 2004.  Under a set of proposals known as Tier II, they are obliged to reduce the sulphur content of their gasoline from the start of this year as well.  Tier II requires refiners to limit sulphur to 120 parts per million (ppm) compared with last year’s ceiling of 500 ppm.  The same standard will apply to gasoline imports.  A few, mainly small refiners will be allowed to produce gasoline up to a limit of 300 ppm, but the overwhelming majority of US gasoline will have to meet the lower limit.

       Not all foreign suppliers will be able to meet the new sulphur specs without changes to their crude slates.  Some Latin American and European refiners may have to switch to crudes that are lower in sulphur, as may some US refiners as well.  This could mean a cut in demand for sour crudes from Canada, Mexico, Venezuela and the Persian Gulf and the corresponding rise in the premium paid for sweet crudes such as those from West Africa and the North Sea.  The same considerations apply to refinery feedstocks such as vacuum gasoil (VGO), which are cracked to produce gasoline.  Late last year, as refiners switched to making low sulphur gasoline the premium in the US Gulf for low sulphur VGO widened from around 80 cents a barrel to nearly $3.00.

       Gasoline markets themselves are bound to become fragmented as US states adopt different specifications.  This can cause problems during temporary shortages of gasoline in some areas, owing to the difficulty of finding product of the right specification from neighbouring states where different rules apply.  Futures trading is also affected.  Nymex has been obliged to introduce a new contract based on the New York and Connecticut grades containing ethanol, after trading in its standard, non-ethanol contract declined sharply.  Two other futures contracts are due to be launched in response to the change in gasoline specifications.  The New York Board of Trade announced the introduction of an ethanol contract in May, while the Chicago Board of Trade said it would have one ready by the end of the year.

 


THE MONTH IN BRIEF

This section summarizes downstream developments of the previous month.  Exploration & Production are covered in ‘Upstream Review’.

Chaos in Iraq, a curious Saudi offer and Shell still in trouble


The USA suffered its highest monthly total of casualties in Iraq during April as the security situation began to spiral out of control.  Middle Eastern worries and high US gasoline demand pushed oil prices to their highest level since shortly after Iraq’s invasion of Kuwait in August 1990, as WTI hit $40.  Insurgents targeted several oil installations in Iraq including the Basrah Oil Terminal and the nearby offshore terminal at Khor al-Amaya.  Exports to Ceyhan in Turkey resumed following damage to the pipeline, only to be suspended in late April for what were described as “technical reasons”.  The Iraqi Governing Council, the US Congress and the United Nations began investigations into the alleged bribery and corruption surrounding payments made in connexion with the UN’s ‘oil-for-food’ deal under which Saddam Hussain’s government sold its oil between 1996 and 2003.

       Saudi Arabia made a curious offer to the USA to build two new refineries there.  Planning regulations make it virtually impossible for anyone to build a new US refinery.  The Saudis’ main aim was to divert criticism for high oil prices away from OPEC and towards the USA, where gasoline prices are soaring amid a shortage of refining capacity and increasing demand (see ‘Focus’).  Saudi Arabia meanwhile has agreed to raise crude oil deliveries to East Asia in an attempt to curb price increases there.  Saudi export volumes will nevertheless be below those contracted for by Asian buyers.  Terrorists killed six people in an attack on the Saudi Aramco-ExxonMobil refinery complex at Yanbu.

       Some members want OPEC to raise its oil price target above the present $22-28 range (see ‘Looking Ahead’).  Iraq is trying to reduce the volumes of its crude sold to traders, preferring to sell directly to refiners instead.  US refiners are showing interest in a blend of Basrah Light crude and Ecuador’s Napo being made available at storage facilities in Panama.  The new blend is said to produce a high quality asphalt.  Russia’s Yukos has agreed to more than double deliveries of crude oil by rail to China this year.  Volumes have been set at 180,000 bpd.  Sinochem is to buy the bankrupt 270,000 bpd Inchon refinery in South Korea.  The Chinese oil trader says it will process its own crude there for export to China.

       Shell’s troubles have continued with the publication of an e-mail from its former head of exploration, Walter van de Vijver, saying he was “becoming sick and tired about lying about the extent of our reserves.”  The company has also announced it is to sell its retail network in Spain and Portugal.  Italy’s ENI is also to give up petroleum marketing, along with refining, in Portugal, as part of a deal enabling it to increase its role in the country’s gas business.  ENI is to take a 49% shareholding in the national utility, Gas de Portugal.  The Czech government has approved a $476 mn bid by Poland’s PKN Orlen for the 63% state-owned downstream company Unipetrol (see ‘Focus’, November 2003).  Another Polish firm, Lotos, is to take minority stakes in three Polish refineries owned by Nafta Polska.

       A subsidiary of US utility Reliant Resources has been charged with manipulating electricity prices in California by deliberately taking generating plants off-line in order to drive up power prices.  The indictment refers to events alleged to have happened in 2000 when the state was plagued by power blackouts and electricity prices soared (see ‘Gas and Power’, August 2002).  The state is claiming $9 bn in compensation from various electricity companies for what it claims was excessive overpricing.  Other companies charged include Enron.

       Qatar Petroleum, Sasol and ChevronTexaco have announced plans for 196,000 bpd of new gas-to-liquids capacity in the emirate based on the expansion of an existing project and the building of a new one (see ‘Focus’, October 2003).  The Philippines has agreed to build the country’s first LNG terminal, to be sited at Mariveles in Bataan Province, alongside a 1.2 GW power station, with completion scheduled for 2007.  Romania is planning to extend its underground gas storage network.  France’s last coal mine has closed.


 

GAS AND POWER

Low gas prices lead to shortages in Argentina


Price controls imposed by the Argentinian government on gas producers have led to widespread shortages.  Wellhead prices were frozen in January 2002 as part of a series of measures designed to deal with Argentina’s economic crisis, but the price controls have only served to boost demand for gas, creating nationwide shortages and forcing the country to import heavy fuel oil in order to keep power stations running.  The government finally agreed to a 37% increase in prices for producers from 1 May, but this is unlikely to do much to relieve the shortage of supply as Argentina goes into the peak period of winter demand.

Gas crisis

The freeze on gas prices helped to reverse a sharp fall in domestic consumption at the start of the decade.  Last year, demand rose by 10% to 3 bn cfd, and demand has continued to increase during 2004, with a further rise of 10% forecast this year.  The largest increase in gas consumption has occurred in the power sector, with a rise in gas use in electricity generation of nearly 13% between 2002 and 2003.

       The power sector is now experiencing shortages of gas as electricity demand approaches its seasonal winter peak.  This year, the situation is made worse by a shortage of hydro-electric power, following several months of low rainfall.  Many hydro-electric plants are reported operating at less than half their installed capacity.  Hydro-electricity usually provides about 40% of the country’s power.

       In an attempt to conserve gas supplies, Argentina has cut its exports to Chile from their contracted level of about 610 mn cfd to 525 mn cfd, forcing generators to import coal and oil in order to keep their stations running.  Large consumers inside Argentina have also had their supplies cut.

Power shortages

Among the large consumers experiencing supply cuts have been several Argentinian generators.  They have responded by switching fuels and reducing electricity exports, whilst the government has begun negotiations with Brazil for the import of electricity.  It has also asked Bolivia to supply 140 mn cfd of natural gas for six months from the start of May.  Bolivia formerly supplied gas from fields operated by Repsol-YPF via a pipeline across the Andes. 

       Venezuela has agreed to provide up to 4.5 mn bbl of heavy fuel oil and 1.6 mn bbl of gasoil in return for agricultural produce and steel.  The fuel oil, however, has a higher sulphur and metals’ content that that permitted by Argentina’s electricity regulator.  This has forced power companies to turn to refiners in Brazil, the Caribbean and the US Gulf for supplies that meet official specifications.  Some fuel oil cargoes have been sought from as far away as Europe.

       As a further measure to conserve gas supplies, Argentinian generators have scaled back exports of electricity to Uruguay, which relies on Argentina for nearly 20% of its supply.  Uruguay has been forced to bring mothballed oil-fired capacity back into operation and has also approached Paraguay and Brazil for emergency electricity supplies.

       Argentina is asking Brazil to supply it with electricity, using the 500 MW interconnexion linking southern Brazil with the Argentinian province of Corrientes (see ‘Gas and Power’, March 2004).  Brazil, however, may not be able to supply the full amount requested by Argentina.  Less than three years ago, Argentina was exporting electricity to Brazil.

Reviving the gas industry

Argentina’s gas production has risen steadily in recent years (see Table 5.2a), but investment has been badly hit by the freeze on wholesale prices, threatening future levels of growth.  The government has accused foreign gas producers of deliberately creating shortages in an attempt to force it to agree to higher prices.

       It is not only the producers, however, that have been suffering from low prices.  Gas distribution companies have also been unable to raise their tariffs, and several have run up large debts as a result.  The Buenos Aires distributor, Metrogas, was forced to default on a debt of more than $400 mn.  Gas tariffs were last raised in May 2002.  An application for a further rise by distributors in December of that year was blocked by the courts.

       Argentina has ambitious plans to increase gas production, as well as to raise the use of gas in power generation (see ‘Gas and Power’, September 2002).  Output is slated to rise from 5 bn cfd to 6 bn cfd between now and 2010, while consumption is forecast to increase by nearly a third to 4.5 bn cfd.  Low wellhead prices could slow down any expansion in production, but a more serious problem may well be the state of the country’s gas transmission system, which is already under strain from rising production.  Unless this is expanded within the next two years or so, Argentina will not be able to go on increasing its production of natural gas

Geopolitical complications

Argentina may well find that it has less gas available in future than currently anticipated.  Given the recent response to gas shortages, the place most likely to be affected by problems in Argentina is Chile.

       Chile has built several gas-fired power stations based on the long term import of gas from the Argentine.  More than a quarter of its generating capacity now consists of combined-cycle gas turbine stations.  Chile’s only real alternative to Argentina as a source of supply is Bolivia, but a territorial dispute dating back to a nineteenth century war prevents any deal between the two countries.  Following the war, Bolivia lost its access to the sea and the government has demanded the right of access to the Pacific Ocean via Chile before it will agree to sell gas to Chile.  It has even been reluctant to sell gas to the Argentinians for fear they will re-sell it to Chile and has written into its contract a clause prohibiting Argentina from raising its exports to Chile as long as it is importing gas from Bolivia.

       Uruguay, on the other hand, may try and replace its lost electricity imports from Argentina by building gas-fired power stations of its own and then fuelling them with gas imported from Bolivia.  Both Uruguay and Chile look like having to pay more for their gas and power in future as a result of this year’s crisis in Argentina.

 


LOOKING AHEAD

Will the world go on pricing oil in dollars?


The weakness of the US dollar has revived the discussion inside OPEC and elsewhere over whether to continue the international pricing of oil in the American currency unit or whether instead to select another unit of account.  The alternative at present is the euro which, after a shaky start in the international market has steadily increased in value against the US currency.

       The debate about changing currency units is not a recent one.  As far back as the 1970s, some OPEC members were considering a switch to a basket of currencies, such as the International Monetary Fund’s Special Drawing Rights (SDR), during an earlier period of dollar weakness.  More recently, the Iraqi president, Saddam Hussain, began to price his oil exports in euros, though this was meant as a gesture of political defiance aimed at the US government rather than as a measure designed to improve Iraq’s economic circumstances.

OPEC worries

Despite a formal proposal by OPEC in 1975 to adopt SDR as a unit of account for the pricing of crude oil, the oil producers stuck with the US dollar, though from time to time they tried to compensate for any significant decline in the purchasing power of the US currency by raising the dollar price of their exports.  In 1981, however, OPEC members became concerned principally with competing with each other  for market share in an oil market that was in sharp decline.  The purchasing power of the US dollar ceased to have much relevance when OPEC members were obliged to take whatever price the market dictated in an era of oversupply and global recession.

       This period came to an end in 1986, when OPEC ministers introduced the concept of the ‘reference price’: a target price for a basket made up of the principal OPEC crudes, expressed in US dollars.  The first such price was $18 a barrel, which was raised to $21 some four years later, before being expressed as a range of $22 to $28 a barrel in March 2000.

       At various times, individual OPEC members tried to persuade some of their customers to pay in currencies other than the dollar, notably the German mark and the Japanese yen.  There was little enthusiasm for such a move amongst importing countries, which preferred where possible to take advantage of their own currencies’ strength in order to reduce their import bills for oil.

Pricing the basket

Dollar weakness has returned since late 2000, but this time, oil prices are rising sharply.  In early May 2004, crude oil prices were at their highest level since just after Iraq’s invasion of Kuwait in August 1990.  This has nevertheless not stopped some producers from calling for oil’s link to the US dollar to be reconsidered.

       Last December, OPEC’s Secretary General, Alvaro Silva said that the organization was evaluating the use of either the euro or a basket of currencies as a way of compensating for the dollar’s decline.  The call for a fresh look at oil pricing has also come from the Russian President, Vladimir Putin, who told the German Chancellor, Gerhard Schröder, that Russia “might consider” pricing its exports in euros.  Since then, EU officials have indicated that they would not entirely be averse to such a move, and the matter has been discussed further at a meeting between the Russian Deputy Prime Minister and members of the European Commission’s Directorate-General of Energy and Transport.

       Mr Putin’s proposal appears to apply principally to Russian crude oil exported by pipeline to Western Europe, raising the spectre of oil pricing by Russia in more than one currency.  Such a step appears unlikely and in any case raises the question of whether the Russians might subsequently request a return to the dollar if the euro were to weaken against the US currency.

       Nor is OPEC likely to switch to the euro or a basket of currencies in the near future.  While Libya and Nigeria have complained that the weak dollar undervalues their exports, there has been no serious call for it to be replaced as the unit of account for oil pricing, and the issue was not formally raised at the group’s ministerial meeting at Algiers on 10 February this year.  Instead there have been calls for a straightforward raising of the target price range in US dollar terms.

       The dollar is likely to remain entrenched as the pricing unit for oil for a number of important reasons.  In the first place, the world’s exports are mainly priced in relation to a small number of non-OPEC crudes such as Brent/BFO, West Texas Intermediate, Dubai, Oman and Tapis, all of which are priced in dollars and where there are no serious proposals to alter the unit of pricing.

       Secondly, hedging of oil prices takes place in dollars in the world’s principal forward, futures and other derivative markets.  A switch to another currency would greatly increase the basis-risk for traders trying to protect their margins.  In many cases, it would make little sense for either buyers or sellers to abandon the dollar.  OPEC sales to the USA are an obvious example, but the same applies almost equally to the crude oil trade between OPEC and East Asia.  This leaves the trade between OPEC and the euro zone, but the use of a separate currency here would simply serve to fragment a more or less integrated world oil market and make oil transfers between world regions less efficient.
