Tertiary recovery techniques are being seriously considered by Middle East oil producers with heavy investment earmarked for the technology

Upstream spending in the Middle East is increasingly being directed towards enhanced oil recovery (EOR) projects to boost the performance of long-serving mature fields, rather than exploring new discoveries.

Oman was the first in the region to adopt EOR techniques and successfully arrested the decline in its output from 2007. Now, other countries are also looking to the technology to get more from their ageing workhorses. Kuwait and the UAE are already executing schemes and international oil companies in Iraq are studying how EOR may benefit its oil sector.

The biggest future market, however, is Saudi Arabia, which is home to both the world’s largest onshore oil field and biggest offshore asset.

Long-running maintenance programmes have proved effective so far in sustaining production levels in the kingdom, but the time is approaching when all Aramco’s mature fields will require extensive EOR techniques.

These projects will be crucial to ensuring Saudi Aramco is able to continue in its role as the world’s swing oil producer. It is this that gives Riyadh its powerful position in the global economy and makes US and Western governments court its political allegiances. For that reason, Aramco is already preparing the groundwork and expanding its Maintain Potential Programme.
