An Abstrat

By Dr Mamdouh G. Salameh*

Overview

In a paper entitled: ”Saudi Arabia’s Proven Crude Oil Reserves & Production Capacity: The Myth & the Reality” I gave at the 28th Annual IAEE International Conference on June 3-6, 2005 in Taipei and also in my latest book entitled: ”Over a Barrel” published in the UK on June 2004, I questioned the size of Saudi Arabia’s claimed proven oil reserves and production capacity. My research then showed that Saudi proven reserves are no more than 181 billion barrels (bb) of oil and not the 264 bb claimed by the Saudis and parroted by the BP Statistical Review of World Energy and the Oil & Gas Journal (OGJ) year after year.

In this new paper, I revisit the topic of Saudi reserves in view of the new outlandish claims that the Saudis have been making about their proven oil reserves, their oil recovery factor (RF) and the amount of oil they initially have in place (OIIP).

Saudi Arabia has effectively used propaganda methods for at least the last fifteen years to convince many governments, corporations and individuals to believe that their remaining proven oil reserves amount to 264 bb of oil, that they have an oil recovery factor of 52% and that their OIIP was 700 bb.

Saudi Aramco claimed that they still have 264 bb remaining recoverable oil reserves as of January 2008. This is unbelievable and has probably been created by artificially increasing their OIIP every year by an amount to exactly offset production. Saudi Aramco claims that the constant remaining recoverable reserves since 1993 has been due to increased discoveries and improved technology. However, oil discoveries since 1993 have been minimal, at most adding about 10 bb to OIIP.

Only one significant discovery has been made since 1975, the Hawtah Trend, a collection of about six fields in 1989-91 with about 2 bb reserves and 6 bb addition to OIIP. However, between 1982 and 2004 there was a total addition of 110 bb to Saudi OIIP, which leaves a very large unaccounted 104 bb. A 2005 Association of Peak Oil (ASPO) presentation showed an increase in discovered reserves of about 5 bb from 1982 to 2004, representing about 15 bb addition to OIIP, which still leaves an unaccounted 95 bb.

Saudi Aramco has kept remaining recoverable crude oil reserves constant simply by artificially increasing the OIIP each year since 1982, accompanied by an unrealistically high average recovery factor of 52% since 1988.

Aramco may have some high recovery factor fields such as Abqaiq and Shaybah, but an average recovery factor of 52% could be easily discounted, given that 90% of Saudi oil production comes from four giant oilfields (Ghawar, Safaniya, Hanifa and Khafji), all of which are more than 50 years old and are being kept flowing by a huge injection of water. Oil recovery rate from these four oilfields ranges between 25% and 30%. Moreover, the trend of the recovery factor for Saudi Aramco indicates that there has been no effect on the recovery factor by recent technological advances in producing wells.

Recovery factors vary according to each field and each part of a field. A recovery factor is defined as the ratio of recoverable oil to the volume of oil initially in place (OIIP). According to ASPO, the average global recovery factor is about 30-35%”. This is based on data from the IHS Energy database on 9,000 fields worldwide containing 1,400 bb of reserves.

The International Exploration company, Schlumberger, discusses recovery factors in their brochure called Carbonate Reservoirs – Meeting unique challenges to maximize recovery. This brochure states that “the average recovery factor is about 35%. However, it is recognized that recovery factors are higher for sandstone reservoirs than for carbonates”. Given that the majority of Saudi Arabia’s key reservoirs are carbonate, it would seem appropriate that 35% is assumed as a reasonable upper limit for the average recovery factor of all fields based on Schlumberger’s statements.

An answer can now be offered to the question: What is Aramco’s purpose of showing a continuous and gradual increase in OIIP without supporting evidence? All oil companies, including state-owned companies such as Saudi Aramco, are under great pressure by their owners to demonstrate replacement of reserves depleted by production. Aramco wanted to continue replacing annual production with new reserves, while assuming a constant RF. In the absence of sufficient real oil discoveries to increase OIIP enough to create new reserves, Aramco decided to artificially increase the OIIP each year to offset annual production. Aramco’s behaviour is evidenced by an unusually high correlation coefficient of 0.99 between cumulative production and the OIIP from 1982 to 2007.

Applying the previously assumed lower and upper global RF limits of 30% to 35% to the more realistic estimate of 580 bb Saudi OIIP gives a range of 174 bb to 203 bb of recoverable reserves. Given that Aramco has cumulative production of 116 bb to the year end 2007, this gives a range of remaining recoverable crude oil reserves from 58 bb to 87 bb not Aramco’s propaganda claim of 264 bb. Even if we accept the Saudi OIIP figure of 700 bb, we come to estimated reserves of 94 bb-129 bb.

Methods

The author will use his own research and collate it with research from other credible sources such as the International exploration company, Schlumberger, and the Association of Peak Oil (ASPO) to present a well-balanced analysis of the Saudi claims and come up with more realistic estimates.

Results

This paper will discuss Saudi claims that their remaining proven oil reserves amount to 264 bb of oil, that they have an oil recovery factor of 52% and that the oil initially in place (OIIP) they have amount to 700 bb. It will argue that far from having 264 bb of recoverable remaining reserves, Saudi reserves are actually less than 100 bb. The paper will prove that Saudi Arabia’s oil recovery factor could not be 52% when the average global recovery factor ranges from 30%- 35% according to the most authoritative sources in the field. It will contend that Saudi OIIP should be realistically estimated at 580 bb and not 700 bb as the Saudis claim.

Conclusions

The paper will conclude that Saudi Arabia has effectively used propaganda methods for at least the last fifteen years to convince many governments, corporations and individuals to accept their repeated claims about proven reserves, oil recovery factor and OIIP and also that they are the world’s leading oil producer. This paper will also conclude that it is high time for the Saudis to come clean about their oil reserves to enable the world to take precautions against an impending global oil disaster before it is too late.
