Twilight in the Desert: The Coming Saudi Oil Shock and the World Economy

This is a well written and well researched book by Mathew Simmons, an expert on the oil business including Middle East oil supplies. The book is a bit technical and is mostly solid information on oil extraction, the oil fields of Saudi Arabia, along with a number of projections. The best comparison that I can make is with a university reference book, but not a text book: it is a well written reference book with a very short introduction of Saudi history. The book is a little over 400 pages in medium font, and has many maps showing the locations of the oil, schematics showing how the crude oil is actually processed, photographs, and a number of tables. There are about a dozen large oil fields in Saudi Arabia. These fields are discussed, and comparisons are made with other large active oil fields around the world, including the North Sea oil fields started in the early 1970s. The core idea of the book is that we are about to face the reality of limited oil production in Saudi Arabia and in the rest of the Middle East: the situation is not good and projected inventories and extraction rates are too optimistic. The era of growing sources seems to be over, regardless of the political situation in the Middle East. The sources cannot keep up with the demand for oil that is expected to continue to grow. The book is divided into four sections and then has a very short appendix. The first section is just 69 pages and details the political and historical development of Saudi Arabia as a country, and the introduction of foreign oil companies. Section two is short, just 50 pages, and covers the subject of how the oil is extracted from the ground, and what has to be done to separate the crude from water, methane, and various other contaminants to get "pure oil". This includes photographs and a number of process schematics. It goes step by step through from the discovery of a field to how the oil is actually extracted and processed, and this can differ for different stages in the life of an oil field. Section three is the heart of the book. It is a long inventory and description of about a dozen Saudi oil fields with maps and comments. This is one of the biggest sections and takes up 110 pages. He goes through the inventory field by field explaining the size, location, problems, yields, lifetimes, etc. This is a relatively complete description of the Saudi oil situation and oil around the Middle East, in more general terms for the latter and a bit less detailed. The last section is about 100 pages and he describes the life cycles of various oil fields to show how the oil extraction rate varies with time. Each field goes through a life cycle, sometimes lasting decades, but each has a finite cycle length and each follows a similar production trajectory, i.e.; a slow rise in output at first to a maximum rate, then a peaking, then a drop off. The author has a lot of detailed information on many oil fields from around the world, along with their production hist

Matt Simmons has bad news about Saudi oil, very bad. Who is Matt Simmons? He's a Houston investment banker who specializes in oil. He's a member of the National Petroleum Council and the Council on Foreign Relations. Not a radical environmentalist, in other words, quite the opposite. What Simmons has done in TWILIGHT IN THE DESERT: THE COMING OIL SHOCK AND THE WORLD ECONOMY is to analyze the technical papers of the Society of Petroleum Engineers (SPE) on Saudi oil, shining a light behind the veil of secrecy that has shrouded it since OPEC stopped reporting oil production data in 1982. In short, what the SPE reports reveal is that the official Saudi claims for reserves and production capacity are vastly overstated. Further, tragically, it seems that the fields have been mismanaged, making it unlikely that all the oil will ever be recovered. Now someone with a suspicious mind might suspect that Simmons, a banker, has an interest in leading the market to believe that oil is scarce, because that will put upward pressure on the price, and the oil companies and he, their banker, will benefit. I do have a suspicious mind, but I am convinced by Simmons's meticulous presentation of the SPE data. It is probably the single most important piece of evidence that the world is entering the Hubbert's peak for oil ("peak oil" as it is colloquially and ungrammatically known). He systematically presents the data on every single big Saudi oilfield, from the biggest of all, Ghawar, which as of 1994 still produced 63% of all Saudi oil, through Abqaiq, Safnaya, Berri, Zulaf, Marjan, Shaybah, and smaller fields. Are there vast untapped reserves in Saudi Arabia? According to the SPE data, the answer is no. No giant fields have been discovered since 1968, despite intensive exploration. Here is a list of crisp facts about world oil, according to Simmons (p. 331): 1) Only a handful of super-giant oilfields have ever been discovered in Saudi Arabia and the Middle East -- they represent a very significant portion of all ME oil, and they are all very mature. 2) All mature giant oilfields peak and decline (production profiles showing the peaks are shown for 8 fields in Texas, Alaska, the North Sea, and Russia). Implication: sophisticated new technology will not prevent or forestall this from happening. 3) There do not seem to be many giant oilfields left to be discovered in Saudi Arabia or the ME. 4) Non-OPEC oil, excluding the FSU (former Soviet Union) seems to be peaking, or has already peaked. The consequences of all this, needless to say, are grim. It's been increasingly clear in recent years that oil had peaked everywhere else, but there was still supposed to be a vast reserve under the Saudi sands. Apparently this was a mirage. What this means is that we have to make the development of new energy sources the top priority! Of course, in the middle to long-term, it will have to be renewable energy, and the faster we move to solar, wi

Simmons' thesis is that Saudi Arabia's reserves and ability to produce current volumes may be on the point of collapse and as a result potentially the world economy. This is a very important book. The world depends upon Saudi oil to power the world economy, but the reserves and production potential that everyone assumes exist, may not. There are 600 million cars in the world and 6.5 billion people-so, 5.9 billion people want a car. World oil market is 82.5 million BOPD with 30 million BOPD from OPEC. IEA estimates 4Q05 oil demand at 86.4 million BOPD or an estimated increase of nearly 4 million BOPD by year end 2005. How will this increase in demand be satisfied? Saudi Arabia is the largest oil producer in the world with current estimated monthly production of 9.2 million BOPD. The world has looked to Saudi Arabia to be the "swing" producer for several decades. The Saudis have invested capital to drill wells and install production infrastructure for which they receive no immediate return to maintain their "swing" producer status. The conventional wisdom is that the Saudi's currently have peak capacity of 10.5 million BOPD. The Saudi government stopped providing production volumes by field in 1982 so it is impossible for outside observers to estimate Saudi production potential or production capacity. If the Saudi's increase their daily production volumes by 1.3 million BOPD, where will the remaining 2.7 million BOPD come from to meet year end 2005 demand? In 1979 Saudi Arabia announced total reserves of 150 billion BO. Also in 1979 they stopped reporting remaining reserves by producing field. By 1988 the Saudi's announced their reserves had increased to 260 billion BO with no significant announced field discoveries. Since 1988 they have produced about 46 billion BO, but still maintain they have remaining reserves of 260 billion BO. It's very difficult to believe that after producing 46 billion BO the remaining reserves have stayed the same-especially since there have been no known major field discoveries. This is where Simmons comes into the debate.

The basis of this book is fear, not unwanted fear spread by the author, but it is the emotion you start to feel as you move through the book page by page. For good or bad the U.S. and the world have become reliant on one natural resource that is controlled by a very few countries and people. This fact alone should have most of us concerned, 60% of the oil we use each day is controlled by a bunch of countries that are primarily dictatorships surrounded by people that would sooner burn the oil in mass dumping grounds instead of selling it to us regardless of the price. We have become backed into a corner and it appears that our only response so far as been to flex our power. What will happen if the oil fields in Saudi can not keep up with demand? What if the production facilities are almost overmatched at this point and further facilities are difficult to put in place? All of these and more questions are covered in this book. The author also talks about the populations and political situation in Saudi and the picture he presents is another difficult and concerning one at that. One can only hope that the production in Iraq gets up and running or that better technology is hurried into production. The footnotes and documented sources detailed in the book give it the appearance of a very well documented and accurate study. The details on the production process in Saudi is worth the price of the book alone. It is a rather back handed slight at our news media that the very real issues presented in this book have not yet made it to the talking heads at 6 pm. Overall I enjoyed the book a great detail. It is well written and put together. The reader is never lost in the detail no matter how little previous knowledge the reader has about the oil business. What I found was that the good was a very fast read given that it is difficult to put it down. It is a book that we all need to read.
