Peak Oil Saudi Arabia 2005?
Tuesday, March 3rd, 2009
The Oil Drum — Saudi Arabia’s historical crude oil production indicates a peak of 9.6 million barrels/day in 2005. In 2008, crude production was 9.3 mbd. In 2009 it is forecast to be 8.1 mbd followed by an increase in 2010 to 8.5 mbd. Unfortunately, after 2010 a steady decline is forecast.
The forecast production profile assumes that Saudi Arabia’s ultimate recoverable crude oil reserves (URR) are 185 billion barrels (Gb). …
A critical forecasting assumption is that the ultimate recoverable crude reserves (URR) for KSA, including half of the Neutral Zone, are 185 billion barrels (Gb) relating to producing fields. KSA may have an additional 25 Gb reserves from future discoveries and from the 65 static (discovered undeveloped) fields in the chart below giving a higher URR of 210 Gb. As oil production from these additional reserves would not start until at least 2015, the decline rate should decrease but the 2005 peak would not be exceeded. The production from these additional 25 Gb of reserves would have only a very small impact on future world crude production. …
Many readers will question the validity of my URR estimates, shown in Figure 1, thinking that the true KSA URR must be higher. A perceived high URR is in the national interest of KSA because it needs its customers to continue their demand for oil leading to sustainable high oil prices for KSA. If customers thought that KSA had less than 100 Gb of oil left then conservation and switching to alternatives would increase. KSA has been creating this perception of overabundant oil reserves for at least sixteen years because it believes that this will maximize the price of its remaining oil.
Mr. Naimi, pictured above right, has said on many occasions that the KSA can add another 200 Gb of reserves. In December 2004, Naimi said that reserves could be bolstered by another 200 Gb. In an April 2008 speech, Naimi was still talking about adding the same 200 Gb to increase remaining recoverable reserves to 464 Gb. In April 2008, cumulative crude oil production of KSA was 114 Gb which means that the his total potential crude URR is about 578 Gb which represents an impossible recovery factor of 96% based on Zagar’s estimate of oil initially in place of 600 Gb (Fig 4).
It is time for Mr. Naimi to tell the truth about remaining KSA reserves. As the true remaining reserves are probably much lower than Naimi’s claimed 260 Gb, a full disclosure of KSA reserves, by field, would not only allow more effective future oil production and consumption planning but might also help increase short term oil prices which would be favourable to all OPEC members.
