The most hyped IPO ever – but what will buyers actually get?

By Gregory Brew, Oilprice.com

The world’s most valuable oil company, Saudi Aramco, is approaching its first IPO in 2018, as the government of Saudi Arabia prepares to sell off portions of the company in order fill a sovereign wealth fund crucial to the country’s transition away from an oil-based economy.

Saudi Aramco is worth $2 trillion, according to Riyadh, and its five percent initial offering could yield $200 billion. This would be the largest IPO in history, blowing away the offering of China’s Alibaba in 2014.

The problem, however, is that the company itself may not be worth as much as the Saudi government claims. Recent reports and growing skepticism regarding Aramco’s actual worth have cast some doubts on whether the world’s largest IPO will be as earth-shattering as originally thought.

The original estimate offered by Saudi Arabia, which placed Saudi Aramco’s worth at around $2 trillion, was based on a valuation of Saudi Arabia’s oil proven reserves, 261 billion barrels. Multiplying at $8 per barrel, those reserves alone are worth $2.088 trillion. When Saudi Crown Prince Mohammed bin Salman made that original estimate, it garnered some skepticism: how could any company be worth such an astronomic sum?

Now, analysts at Wood Mackenzie have conducted their own study of Saudi Aramco, and came up with a completely different (and much lower) figure. WoodMac puts Aramco’s true value closer to $400 billion, eighty percent less than the Saudi estimate, and it arrived at the figure by considering future demand and the anticipated average price of oil (on which profits will depend), as well as Saudi Aramco’s status as a state-run company.

WoodMac doesn’t dispute the figure of 261 billion barrels lying under Saudi Arabia and just offshore; that figure has been confirmed by independent sources. Where things get complicated, though, is in the management and taxation of Saudi Aramco, which does not release financial statements. It is known that the company, which is the bedrock of the Saudi economy and the major foundation for state finances, pays a twenty percent royalty on revenues and an 85 percent income tax, supporting the Saudi government and providing a living for the 15,000 members of the Saudi royal family. Tax commitments of that size could have a major impact on the company’s profitability, leaving little in dividends, a factor WoodMac considered in its valuation.




There’s also the question of investors demanding discounts for investing in state companies. Bloomberg noted that Saudi Arabia, while a comparatively stable Middle Eastern nation, could encounter the kinds of problems and instabilities plaguing other resource-rich countries with large, state-run energy companies. There are questions surrounding the viability of the country’s long-term economic plan, Vision 2030, which anticipates a major shift in the Saudi economic outlook away from oil and gas and towards greater diversity.

Bloomberg also noted that the Saudi tactic of computing the company’s price according to its held proven reserves doesn’t add up: Russia’s Rosneft, by that accounting, should be worth $272 billion instead of its current value of $64 billion, while the value of ExxonMobil, the world’s most valuable private energy firm, would be fifty-three percent less.

Other commentators who spoke to Bloomberg off the record put the company’s true value somewhere between $500 billion and $1 trillion.

WoodMac has predicted prices in 2017 to remain relatively stable, if OPEC continues to abide by its production agreement, and believes the average price will be as high as $57 per barrel. But looking further ahead, the firm (and other forecasters) are uncertain how electric cars, climate change, technological improvements and changes in demand will affect prices.

This uncertainty also affects the estimates surrounding Aramco’s real worth. Massive Saudi reserves are large enough to sustain current production for another 73 years, so the forecast looks good. But while Riyadh expects peak crude oil demand to come in 2035, other forecasters are much more pessimistic: OPEC has indicated that peak demand could come in as little as a decade, while others are hinting it could come even earlier.

A major facet of the Vision 2030 plan is the surety of future world oil demand: the Saudis must hope that Saudi crude remains attractive and competitive, even as it moves its economy away from relying solely on Aramco’s business. And even if the country sells off its state-run company, Saudi interest and investment will remain closely tied to world oil, as the recent decision to invest $7 billion in an oil processing plant in Malaysia makes plain.

So, even if Saudi Arabia succeeds in selling off Saudi Aramco, perhaps for $2 trillion or perhaps for much, much less, it’s economy and the well-being of its royal family will depend on the world’s demand for oil and gas. By Gregory Brew, Oilprice.com

    Same crap buyers will get with the upcoming Snapchat IPO, I am betting, or what they got for the Alibaba IPO, or many other crap that has come to the market.

    FOMO,OPM, and finally NIRP will take care of things. And don’t forget, The Muppets.

    “Saudi Arabia’s oil proven reserves, 261 billion barrels.”

    I don’t believe that, the Saudis have declining reserves, the idea that they keep growing year by year is a scam.
    The US is in on the scam, because the US dollar price is based on Saudi oil.

      Reserves are developed and added to incrementally, they are not inventory never to be added to. Do we believe that there will be no future additions to Saudi reserves? That there will be no further exploration or development?
      This was the mistake in the late ’70s, when forecasts were presented in the media, based on data from analysts, that claimed we would run out of oil in 1987.
      An analogy would be to take an inventory in a department store, and demonstrate that by reducing inventory by annual sales, that the store would run out of goods and be out of business in x number of years.

    This report was recently distributed by HSBC to clients:

    Brace for the oil, food and financial crash of 2018

    80% of the world’s oil has peaked, and the resulting oil crunch will flatten the economy

    New scientific research suggests that the world faces an imminent oil crunch, which will trigger another financial crisis.

    A report by HSBC shows that contrary to the commonplace narrative in the industry, even amidst the glut of unconventional oil and gas, the vast bulk of the world’s oil production has already peaked and is now in decline; while European government scientists show that the value of energy produced by oil has declined by half within just the first 15 years of the 21st century.

    Last September, a few outlets were reporting the counterintuitive findings of a new HSBC research report on global oil supply. Unfortunately, the true implications of the HSBC report were largely misunderstood.

    The HSBC research note — prepared for clients of the global bank — found that contrary to concerns about too much oil supply and insufficient demand, the situation was opposite: global oil supply will in coming years be insufficient to sustain rising demand.
    Yet the full, striking import of the report, concerning the world’s permanent entry into a new age of global oil decline, was never really explained.

    The report didn’t just go against the grain that the most urgent concern is ‘peak demand’: it vindicated what is routinely lambasted by oil majors as a myth: peak oil — the concurrent peak and decline of global oil production.

    The HSBC report you need to read, now

    INSURGE intelligence obtained a copy of the report in December 2016, and for the first time we are exclusively publishing the entire report in the public interest.

    Read and/or download the full HSBC report by clicking below:

    Headquarted in London, UK, HSBC is the world’s sixth largest bank, holding assets of $2.67 trillion. So when they produce a research report for their clients, it would be wise to pay attention, and see what we can learn.

    Among the report’s most shocking findings is that “81% of the world’s total liquids production is already in decline.”

    Between 2016 and 2020, non-OPEC production will be flat due to declines in conventional oil production, even though OPEC will continue to increase production modestly. This means that by 2017, deliverable spare capacity could be as little as 1% of global oil demand.

    This heightens the risk of a major global oil supply shock around 2018 which could “significantly affect oil prices.”

    The report flatly asserts that peak demand (the idea that demand will stop growing leaving the world awash in too much supply), while certainly a relevant issue due to climate change agreements and disruptive trends in alternative technologies, is not the most imminent challenge:

    “Even in a world of slower oil demand growth, we think the biggest long-term challenge is to offset declines in production from mature fields. The scale of this issue is such that in our view rather there could well be a global supply squeeze some time before we are realistically looking at global demand peaking.”

    Under the current supply glut driven by rising unconventional production, falling oil prices have damaged industry profitability and led to dramatic cut backs in new investments in production. This, HSBC says, will exacerbate the likelihood of a global oil supply crunch from 2018 onwards.

    Four Saudi Arabias, anyone?

    The HSBC report examines two main datasets from the International Energy Agency and the University of Uppsala’s Global Energy Systems Programme in Sweden.
    The latter, it should be noted, has consistently advocated a global peak oil scenario for many years — the HSBC report confirms the accuracy of this scenario, and shows that the IEA’s data supports it.

    The rate and nature of new oil discoveries has declined dramatically over the last few decades, reaching almost negligible levels on a global scale, the report finds. Compare this to the report’s warning that just to keep production flat against increasing decline rates, the world will need to add four Saudi Arabia’s worth of production by 2040. North American production, despite remaining the most promising in terms of potential, will simply not be able to fill this gap.

    Business Insider, the Telegraph and other outlets which covered the report last year acknowledged the supply gap, but failed to properly clarify that HSBC’s devastating findings basically forecast the longterm scarcity of cheap oil due to global peak oil, from 2018 to 2040.

    The report revises the way it approaches the concept of peak oil — rather than forecasting it as a single global event, the report uses a disaggregated approach focusing on specific regions and producers. Under this analysis, 81% of the world’s oil supply has peaked in production and so now “is post-peak”.

    Using a more restrictive definition puts the quantity of global oil that has peaked at 64%. But either way, well over half the world’s global oil supply consists of mature and declining fields whose production is inexorably and irreversibly decreasing:

    “If we assumed a decline rate of 5%pa [per year] on global post-peak supply of 74mbd — which is by no means aggressive in our view — it would imply a fall in post-peak supply of c.38mbd by 2030 and c.52mbd out to 2040. In other words, the world would need to find over four times the size of Saudi Arabia just to keep supply flat, before demand growth is taken into account.”

    What’s worse is that when demand growth is taken into account — and the report notes that even the most conservative projections forecast a rise in global oil demand by 2040 of more than 8mbd above that of 2015 — then even more oil would be needed to fill the coming supply gap.

    But with new discoveries at an all time low and continuing to diminish, the implication is that oil can simply never fill this gap.

    Oil discoveries have collapsed. And even when oil was over $100 activity was weak.

      It does look like there is plenty of oil around untapped reserves exist in Saudi Arabia, Iraq, elsewhere in the Middle East and Iran in particular, Mexican Gulf, East Siberia, Kazakhstan, Alaska, Artic Sea, Venezuela and Canada. But on the other hand the conventional oil production seems to have peaked at 74 bpd and everything else will have to come from unconventional sources, off-shore, etc. These sources will require much higher prices. And despite push to renewables, electrification and gas oil demand is likely to grow just for the reason that there will probably be another billion people rising to the level of the “golden billion” and another billion to where that next golden billion is now. The decline of 5% is about 4 bpd annually that need to be replaced and 20 bpd over 5 year period. That is a lot. The problem, however, may be in the fact that the decline rates may actually become much higher with some mature fields in China, North Sea, Mexican Gulf and elsewhere being simply shut down. If this overlaps with spike in demand due to the combination of monetary stimulus, rising living standards in the developing world (Asia in particular) and some major supply disruption (as was the case with the previous spike), the scene will be set for another spike within two to fours years. The oil producers should be ready for that to benefit.

      Dr. Louis Arnoux has summed things up in the oil extraction business as:
      Oil was once, long ago, quite easy to get from shallow wells, and at very low cost; cost being defined as energy needed to acquire versus energy gained after processing.

      Today, we need to spend a lot of energy to get oil out of the ground. While the amount of energy needed to extract varies widely based on geography, this cost is steadily rising. In less than a decade, it will be an energy stalemate in the sense that the cost to extract, transport, refine and distribute will equal the energy used to get the finished product.

      There will be oil underground, but will it cost as much to get as it is worth in the end? I do not profess to have any insight on this.

    5% of 2 trillion is not 200 billion but 100 billion, a small mistake of 100 billion dollars for your attention, otherwise a very good article indeed

    Saudi’s supposed diversification away from oil requires some scrutiny. They have the huge petro chemical SABIC but it’s major feedstock is gas which it gets at subsidized prices and I have been told it would be in serious trouble if it paid market price. They are also branching into aluminium production, again made viable by a nice gas allocation. Similarly fertilisers – the ammonia ingredient from subsidized gas. Even the dairy business. The milk comes from cows reared in air cooled pens eating feed grown using water produced by desalination. The amount of water used per litre of milk produced is astronomical.

    “…proven reserves, 261 billion barrels. Multiplying at $8 per barrel, those reserves alone are worth $2.088 trillion.”

    Handsome figures, but only unmaterialized dreams. As long as that oil is beneath the ground these number are just that, handsome figures. I wouldn’t pay full value just for handsome figures, i would demand also a proof that those handsome figures do materialize above ground in barrels in some realistic time span. With only handsome figures and benevolent promises with smiles i would discount current value well below publicly offered value. And that’s the risk discount in this case.

    One can promise anything but keeping the promises is totally different thing even if one has good and honest intentions behind promises. Life is ruthless and unforgiving even for best intentions.

    I have read the 261 billion barrels of oil number for over 40 years. This was the number touted as early as 1971! Do they mean to say that the kingdom’s oil reserves are unchanged over a 45-year time frame?

    I understand that the reserves do get replenished by new drilling and expanding the basins, but to present the same number over such an extended time frame sounds ludicrous. Perhaps Wood Mackenzie should have questioned that number.

    On another note, what exactly is Saudi Arabia selling? Are they including the oil fields as part of the deal? I was informed last year that they were only selling 5% of their refining operations, since their law currently forbids selling the underground reserves, following the pattern of every other country in the Middle East; they couldn’t sell the land. In the past, they all would only lease the right to develop the oil, not the oil itself. Has this changed since last year? Not that I know.

    I dispute the Saudi Aramco Reserve numbers:

    Investigating Wikileaks Claim that Saudi Arabia Oil Reserves are Overstated

    It is well known that in 2011 Wikileaks reported that the Saudi Aramco oil reserves were overstated by as much as 40%. As reported in the Guardian, Sadad al Hussini, former Saudi Aramco exploration chief, stated that “recoverable reserves are overstated by 300 billion barrels (Bbbl)” Many other oil analysts concur with this view. Saudi Aramco disputes this statement and insists that recoverable reserves are much higher than the skeptics contend. This paper will attempt to explain, in laymen terms, the oil reserve situation in Saudi Arabia, and investigate the accuracy of the Wikileaks claim.

    Reserves Calculation
    Oil reserves are calculated by this simple equation:
    Present Reserves = Initial Reserves – Production + Discoveries.
    Initial Reserves
    The last audited, published production and reserve calculation for Saudi Aramco was done in 1980 by BP. Production and reserve figures have been secret since then. BP calculated the proven recoverable reserves to be 260 billion barrels in 1980. This will be used for the Initial Reserves. Saudi Aramco states that the current, proven, recoverable reserves are still 260 billion barrels.
    Production
    Figure 1, below, from the USEIA, lists the annual and total oil production from Saudi Arabia from 1980 to 2015. The production since 1980 totals 110 billion barrels.
    Two of the three variables in the equation are now known with reasonable certainty:
    Current Reserves = 260 – 110 + Discoveries
    Discoveries
    There has only been one significant oil discovery in Saudi Arabia since the 1960’s, the Hawtah Trend. The problem is that the primary producing formation, the “Arab D” formation, does not exist outside the immediate Gulf area.
    Hawtah Trend
    The Oil Drum reports that the only oil discovery in Saudi Arabia since the 1960’s is the Hawtah (Najd) Trend, discovered in 1988, which reportedly had an initial production rate of 400,000 barrels per day (BPD) from a group of nine small fields. Saudi Aramco added 30 billion barrels to their reserves in 1988 for the Hawtah Trend. It would take 2 centuries to produce 30 billion barrels at 400,000 BPD, and the field production had already declined by 50,000 BPD by the early 1990’s. Extrapolating this decline rate, I estimate the field had initial reserves of 5 billion barrels.
    Other Reserve Additions
    Other reported reserve additions are as follows (from World Oil Magazine):
    Shaybah: Discovered in 1968 but was not brought online until 1998 at 500,000 BOPD. Production was increased to 750,000 BOPD in 2009. Reserves are reportedly 14 billion barrels. Using typical decline curves, I estimate the field has proven recoverable reserves of 2 billion barrels.
    Khurais: The Khurais field was discovered in 1957 and shut down in 1961. The oil reservoir had little pressure and required water injection to initiate production. In 2009, water injection was initiated which increased production to 1.2 million BOPD. Aramco assigned 19.4 billion barrels of reserves to Khurais. Using a typical decline curve, I estimate the proven, recoverable reserves of this field to be 3 billion barrels.
    Manifa: Discovered in 1957 but shut down almost immediately because the oil was extra heavy and contaminated with H2S and vanadium. The field was put on line in April 2013 and was reportedly producing 900,000 BOPD in 2014. Aramco states that the production rate will increase to 1.4 million BOPD. Aramco assigned 11 billion barrels of reserves to Manifa. Using a typical decline curve, and an initial production rate of 1.4 billion BOPD, I estimate that this field has proven, recoverable reserves of 8 billion barrels.
    Technology Improvements
    In 1988, Saudi Aramco increased their reserves by 70 Billion barrels for “technology improvements”, like horizontal drilling. The reserve number is suspect and politically motivated, according to the Oil Drum. Horizontal drilling in the KSA oil fields would only increase the short term production rate, not the reserves. It is more likely that the reserve increase was politically motivated since Aramco was negotiating with OPEC for an increased share of production. I estimate the reserve additions due to technology improvements to be zero.
    All of my reserve estimates are very rough since there is very little public information available. However, I think my estimates are closer to reality than the numbers released by Aramco. Reserve additions since 1980 are therefore 5+2+3+8=18 billion barrels.
    Remaining reserves for Aramco should therefore be in the neighborhood of:
    Remaining reserves = 260 – 110 + 18 = 168 Billion barrels
    Aramco still estimates the remaining proven, recoverable reserves to be 260 billion barrels, despite producing 110 billion barrels since 1980 and having few reserve additions. My rough estimate is therefore 35% less than the stated Aramco reserves. This is close to the reserve number reported by Wikileaks, who stated that reserves were overstated by 40%.

    Production Rate
    A number that is more important than reserves is the sustainable production rate. The sustainable production rate has a problem called “Ghawar”.
    Ghawar Field
    The Ghawar field was discovered in 1948, and is by far the largest oil field in the world and is 3 times the size of the second largest oil field in the world. The field has had a water production problem since the 1970’s and is nearing the end of its’ producing life.
    The producing formation is a carbonate (limestone) called the “Arab D” formation, with a thickness of 250 feet. The formation is in the shape of an elongated dome with a length of 174 miles. Oil occupies the higher elevations of the dome. Salt water occupies the lower elevations. The field is underlain by an active aquifer which fills the lower elevations of the reservoir with water as the oil is produced from above. This helps to sustain the reservoir pressure. The Ghawar field has produced 5 million BOPD for decades and continues to produce 6% – 8% of the world’s oil production.
    The Aramco engineers employed a unique method of injecting water into the aquifer along the periphery of the field during the primary production phase. Water injection rates are 8 million BWPD in Ghawar to sustain oil production of 5 million BOPD. A total of 12 million BWPD is injected into all Saudi oil fields in this manner to sustain reservoir pressure, according to the book, “Twilight In the Desert”.
    Most Saudi oil fields were producing large volumes of water by the end of the 1970’s. The Aramco engineers began an aggressive recompletion program to reduce the water production. When a well starts producing water, the water has a tendency to “crowd out” the oil due to waters’ lower viscosity. Most of the producing wells had an “open-hole” completion, where there is no production casing across the producing formation. Aramco ran production casing into many wells and then perforated the upper levels of the oil reservoir in an effort to produce the oil without water. This resulted in water cuts being reduced only slightly, according to “Twilight in the Desert”.
    In the 1990’s, the original vertical oil wells were abandoned and replaced by new horizontal wells. The new wells were drilled horizontally in the upper elevations of the oil reservoir, to keep the wells away from the encroaching aquifer.
    Aramco engineers had published articles through the Society of Petroleum Engineers for decades, outlining the production problems and their remedies for controlling the problems. Each article in itself does not indicate a significant, country-wide problem. Matt Simmons was the first to read all the articles and piece together the puzzle of the Saudi Arabian oil fields. He realized that maintaining the oil production has been a constant struggle, over a period of decades, involving the deployment of substantial capital and the employment of state-of–the-art technology. This was covered in detail in the book “Twilight In the Desert”.
    The Oil Drum also estimated a decade ago that the aquifer was beginning to encroach into the upper levels of the reservoir. When the water level reaches the horizontal wells, the individual wells will “water out” in a short period of time. As the water level works its’ way up to the upper elevations of the reservoir, the production rate will exhibit steep declines. It is of utmost importance to know the rate of decline that is expected, and when the decline will begin.

    Ghawar Decline Rate
    One way to estimate the production decline rate for Ghawar is to examine the decline rates for other similar fields. Oil fields completed in limestone formations tend to have higher decline rates than sandstone formations. Limestone tends to have a lot of fractures, which become super highways for water.
    According to “Twilight in the Desert”, The Yibal field in neighboring Oman has the most in common with Ghawar. This carbonate reservoir also has an active aquifer, with additional water injected into the lower elevations, in the periphery of the field. When the original vertical wells began producing excessive water, the wells were abandoned and replaced with horizontal wells. Engineers were shocked at the steepness of the decline rates and had to substantially reduce the expected remaining reserves of the field. The annual decline rate from peak production is 22%.
    Zero Hedge reported that the Haradh field in Saudi Arabia declined by 60% between 2006 and 2010. This decline rate is 20% per year.
    If Ghawar declines at a rate of 22%, production declines could be similar to the table below:

    Daily
    Production
    Year BOPD
    Current 5,000,000
    1 3,900,000
    2 3,042,000
    3 2,372,760
    4 1,850,753

    In 4 years, 3.2 million BOPD of production will be lost, just from the Ghawar field. This problem will be replicated in many Saudi fields, and many others in the Arab Gulf area. There are no new oil fields in Saudi Arabia large enough to replace this production.
    When will the production rate begin to decline?
    If this were a conventional oil reservoir, this question could have been answered accurately in the 1960’s. The active aquifer complicates the reserves calculation, because the production rates and pressures have remained constant for decades. This is further complicated by the existence of the horizontal wells. If the wells were vertical, the increases in the water cuts could be extrapolated to the point where the well becomes uneconomic. When the water level reaches a horizontal well, production from that well will “water-out” completely in a short period of time. When the lower elevation horizontal wells start watering out, the water level will continue to rise and eventually water out the higher elevation wells. As the water level works its’ way up to the higher elevation wells, the field will experience steep production declines. One way to determine when this will happen is to drill observation wells to measure the water level. This data has to be input into a sophisticated computer reservoir model. Aramco has observation wells and a reservoir model that was developed in-house. Complicating the reserves calculation is the fact that field production data has been secret since 1982, as are the results of the computer model. This leaves us with having to make a guess.
    The Oil Drum reported that there are indications that the level of the aquifer is starting to encroach into the upper levels of the reservoir but it’s anyone’s guess when the production rate will begin to decline. My hunch is that it is no longer a long term problem, it is now a short term to medium term problem. If the production rate begins to decline in 10 years, the remaining reserves for Ghawar would be in the range of 25 billion barrels and not the 70 billion estimated by the IEA.

    Conclusions
    • There is ample evidence which indicates the Aramco oil reserves are significantly overstated, as reported by Wikileaks..
    • Proven, recoverable oil reserves are closer to 168 billion barrels than the 260 billion barrels claimed by Saudi Aramco.
    • The sustainable production rate will decline rapidly when the level of aquifer in the Ghawar field approaches the higher elevations of the reservoir. It is not known when this will occur, but it is reasonable to assume that this is a short term to medium term problem.
    • In order to properly price an Aramco IPO, reserves must be audited by an independent engineering firm.
