Kuwait Shell Sheds Light on the Importance of Enhanced Oil Recovery
During the conference, Kuwait Shell, represented by Dr. Zara Khatib, Technology Manager in Shell Upstream International, Middle East Region, facilitated an informative workshop that highlighted the role of EOR, an important technique to increase the amount of oil that is recovered from an oil reservoir.
Shell has been at the forefront of EOR development since the early 1930s, when it first applied steam recovery in California. World wide, Shell applies EOR technology by using three primary techniques: injecting steam to heat reservoirs which makes the oil less viscous and improves it ability to flow; injecting gas which also reduces viscosity, or injecting chemicals that free trapped oil. Chemicals are sometimes used to help lower the surface tension that can prevent oil droplets from moving through a reservoir. All three of these innovative EOR techniques are currently being developed at full field projects in Oman.
Kuwait Shell Chairman, Mr. Ahmed Mouti said: “Energy across the world is being consumed daily at incredible rates. World energy demand is expected to double by 2050 as people strive to improve their living standards. Getting more from existing fields will be a key part of meeting the world’s growing demand for energy. Applying Improved and Enhanced Oil Recovery techniques to extract the oil that would otherwise be left behind is an important part to meet that need. Shell’s technologies help extend the lives of oil fields and maximise our existing resources.
“When an oil field reaches the end of its normal life a great deal of oil is still left in the ground because it is too difficult or too expensive to get out. It is estimated that improving the recovery rate by just 1% extra throughout the world would equate to 20-30 billion barrels of oil. That’s why Shell’s technology is focused on producing extra barrels through the use of enhanced oil recovery.”
Mouti further pointed out that the oil and gas markets of the 21st century are fast-changing and global. In addition to acquired technologies that help maximise natural resources, there must be vital cooperation and value driven partnerships between international and national oil companies to help secure future world energy supply. Partnerships created for the long term that retains their unity in difficult times, enhancing stability and generating economic value for nations and companies alike.
The conference, organised by Kuwait University and the Society of Petroleum Engineers (SPE), covered topics that include economic growth, energy demand, reservoir characterisation, modeling and management, heavy oil tight gas and has condensates, drilling and well completion.
